The study of desiccation tolerance of lichens, and of their chlorobionts in particular, has frequently focused on the anti-oxidant system that protects the cell against photo-oxidative stress during dehydration/rehydration cycles. In this study, we used proteomic and transcript analyses to assess the changes associated with desiccation in the isolated phycobiont Aste-rochloris erici. Algae were dried either slowly (5?6 h) or rapidly (<60 min), and rehydrated after 24 h in the desiccated state. To identify proteins that accumulated during the drying or rehydration processes, we employed two-dimensional (2D) difference gel electrophoresis (DIGE) coupled with individual protein identi?cation using trypsin digestion and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Proteomic analyses revealed that desiccation caused an increase in relative abundance of only 11?13 proteins, regard-less of drying rate, involved in glycolysis, cellular protection, cytoskeleton, cell cycle, and targeting and degradation. Tran-scripts of ?ve Hsp90 and two b-tubulin genes accumulated primarily at the end of the dehydration process. In addition, transmission electron microscopy (TEM) images indicate that ultrastructural cell injuries, perhaps resulting from physical or mechanical stress rather than metabolic damage, were more intense after rapid dehydration. This occurred with no major change in the proteome. These results suggest that desiccation tolerance of A. erici is achieved by constitu-tive mechanisms.

Lichens and their algal partners are desiccation-tolerant organisms and as such survive after the complete loss of water. This trait is the consequence of several physiological, biochemical and structural features, including specific mechanisms dissipating excess light to avoid photooxidative stress. The maximum quantum yield of photosystem II (PSII; Fv/Fm) is widely used as a sensitive indicator of photosynthetic performance and is calculated after complete relaxation in darkness of the fluorescence quenching associated with active light energy dissipation mechanisms. Unexpectedly, we observed that lichens and isolated chlorobionts (chlorophyte symbionts in lichen) maintained in darkness for several hours showed a strong decrease in the ratio Fv/Fm, which was reversible after re-illumination. We analyzed this dark-induced Fv/Fm decay in the chlorobiont Asterochloris erici through steady-state and fast-induction kinetics of chlorophyll a fluorescence and simultaneous P700 oxidation measurements. We found that the gradual decay of Fv/Fm in darkness was caused by reversible dark-induced inactivation of some PSII reaction centers that was accompanied by a decrease in the flux of electrons to PSI. Darkness induced the plastoquinone-reductase activity associated with chlororespiration and the phosphorylation of light harvesting complex (LHC). We propose that upon phosphorylation the LHC detaches from PSII, resulting in a decrease of exciton-trapping by PSII reaction centers and, consequently, an increased dissipation of light energy. This mechanism probably serves an ecophysiological function in lichens to prevent the damage at dawn or under strong fluctuating light conditions when lichens are in a hydrated state.

Background: Cheiloscopy is a comparatively recent counterpart to the long established dactyloscopic studies. Ethnic variability of these lip groove patterns has not yet been explored. Aim: This study was a collaborative effort aimed at establishing cheiloscopic variations amongst modern human populations from four geographically and culturally far removed nations: India, Saudi Arabia, Spain and Nigeria. Subjects and methods: Lip prints from a total of 754 subjects were collected and each was divided into four equal quadrants. The patterns were classified into six regular types (A?F), while some patterns which could not be fitted into the regular ones were segregated into G groups (G-0, G-1, G-2). Furthermore, co-dominance of more than one pattern type in a single quadrant forced us to identify the combination (COM, G-COM) patterns. Results and conclusion: The remarkable feature noted after compilation of the data included pattern C (a bifurcate/branched prototype extending the entire height of the lip) being a frequent feature of the lips of all the populations studied, save for the Nigerian population in which it was completely absent and which showed a tendency for pattern A (a vertical linear groove) and a significantly higher susceptibility for combination (COM) patterns. Chi-square test and correspondence analysis applied to the frequency of patterns appearing in the defined topographical areas indicated a significant variation for the populations studied.

Two intervarietal hybrids of common wheat, Triticum aestivum L., are meiotically analyzed using the C-banding staining method. The C-banding pattern of nine meiotic chromosomes (4A, 7A, and the seven of the B genome) permitted their unequivocal recognition at first metaphase plates. The pairing frequency of each B-genome chromosome arm was scored. Data on the pairing frequency of the arms, separately considered, are applied to calculate expected pairing of whole chromosomes and whole genomes. The application of mathematical models to predict the genome pairing using either equal or different frequencies per chromosome arm is discussed.Key words: meiotic analysis, Triticum aestivum L., C-banding.

An investigation of chromosome structure was made in the following lines of
hexaploid wheat: '113', '114' and '119' (derived by selling from [(T. aestivum L.
•cv 'H-53' x S. cereale L.) x T. aestivum L. cv. 'H-SS']) and '6801', '6805' and '6829'
(derived by selfing from the hybrid Triticale-6x cv. 'Cachirulo' x T. aestivum L.
•cv. 'Marfed ERT-l'). The chromosome structure of all varieties differ from the
•primitive chromosome structure of 'Chinese Spring' by one ('119'), two ('US',
"6801', '6805' and '6829') or three translocations (114'). Analyzing the meiosis of
.crosses between monosomic lines of 'Chinese Spring' with '114', '6801',
'6805' and '6829', it was found that two main reciprocal translocations involving
•chromosomes 1A and 4D on one hand, and chromosome 3D and other no iden

''OSOS', '6829' and 'Marfed ERT-l' is presumed to have in common one important
itranslocation involving1 the chromosomes ID and 4D relative to 'Chinese Spring'.

Lichens are poikilohydric symbiotic organisms that can survive in the absence of water. Photosynthesis must be highly regulated in these organisms, which live under continuous desiccation-rehydration cycles, to avoid photooxidative damage. Analysis of chlorophyll a fluorescence induction curves in the lichen microalgae of the Trebouxiophyceae Asterochloris erici and in Trebouxia jamesii (TR1) and Trebouxia sp. (TR9) phycobionts, isolated from the lichen Ramalina farinacea, shows differences with higher plants. In the presence of the photosynthetic electron transport inhibitor DCMU, the kinetics of Q(A) reduction is related to variable fluorescence by a sigmoidal function that approaches a horizontal asymptote. An excellent fit to these curves was obtained by applying a model based on the following assumptions: (1) after closure, the reaction centers (RCs) can be converted into "energy sink" centers (sRCs); (2) the probability of energy leaving the sRCs is very low or zero and (3) energy is not transferred from the antenna of PSII units with sRCs to other PSII units. The formation of sRCs units is also induced by repetitive light saturating pulses or at the transition from dark to light and probably requires the accumulation of reduced Q(A), as well as structural changes in the reaction centers of PSII. This type of energy sink would provide a very efficient way to protect symbiotic microalgae against abrupt changes in light intensity.

Galactolipids (GLs) are the main lipids in chloroplast membranes and by default are also the most abundant polar lipids on earth. GLs with one or two galactose residues, monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG), are ubiquitous and essential for photosynthesis. GLs with a headgroup formed by three to five galactoses, the so-called oligogalactolipids (OGLs), are only detected in some taxa, organs and environmental conditions. OGLs can be synthesized by two metabolic pathways: successive galactosylation by DGDG synthase (DGD) or transgalactosylation from MGDG by the GL:GL galactosyltransferase (GGGT/SFR2). While the first route appeared early in the evolution (cyanobacteria), the second evolved associated to the process of terrestrialization in the streptophytes. Both routes also differ on the anomeric type of glycosidic linkages formed: ?-type in DGD and ?-type in GGGT/SFR2. Despite functional differences between both configurations, the anomeric analysis of OGLs allows tracking their biosynthetic origin. While ?-OGLs are constitutive and present in some algae and non-vegetative organs of vascular plants, ?-OGLs are typically stressinducible in photosynthetic tissues. Land colonization by plants involved new challenges, such as the risk of dehydration, which required developing biochemical and physiological strategies to stabilize chloroplast membranes and safeguard their functioning. Based on the integrated assessment of data available we propose that the appearance of OGLs was one of those adaptations that simultaneously could have provided advantages against other environmental constraints such as freezing

Phospholipase D (PLD) and its cleavage product phosphatidic acid (PA) are crucial in plant stress-signalling. Although some targets of PLD and PA have been identified, the signalling pathway is still enigmatic. This study demonstrates that the phosphoprotein At5g39570, now called PLD-regulated protein1 (PLDrp1), from Arabidopsis thaliana is directly regulated by PLDa1. The protein PLDrp1 can be divided into two regions with distinct properties. The conserved N-terminal region specifically binds PA, while the repeat-rich C-terminal domain suggests interactions with RNAs. The expression of PLDrp1 depends on PLDa1 and the plant water status. Water stress triggers a plda1-like phenotype in PLDrp1 mutants and induces the expression of PLDrp1 in plda1 mutants. The regulation of PLDrp1 by PLDa1 and environmental stressors contributes to the understanding of the complex PLD regulatory network and presents a new member of the PA-signalling chain in plants.

Se ha estudiado durante seis años consecutivos el número y la localización de los esporocarpos de Amanita ponderosa
Malençon & R. Heim en una parcela de 3 ha ubicada en un encinar adehesado localizado en el Parque Natural
«Sierra de Aracena y Picos de Aroche» (Huelva). Los datos indican que las áreas productoras de setas presentan un
tamaño y una forma similares año tras año, aunque algunas zonas específicas muestran variaciones que sugieren la
existencia de cierta alternancia o vecería. Esta especie fructifica solamente en primavera durante seis a ocho semanas,
desde mediados de febrero hasta abril, cuando comienza a ascender la temperatura media tras el invierno. Las diferencias
observadas en la duración del periodo de fructificación y la producción total de setas dependen fundamentalmente
de las lluvias y la temperatura. Los resultados sugieren que las lluvias tempranas a finales de verano o
principios de otoño son cruciales para la fructificación de la primavera siguiente, y que las lluvias caídas durante el
periodo de fructificación tienen una menor influencia. Durante el periodo de fructificación, la producción es muy dependiente
de la temperatura del suelo.

Cordyceps sinensis (Berk.) Sacc. es un hongo ascomiceto perteneciente a la familia Clavicipitaceae del orden Hypocreales, parásito de artrópodos, que ha sido altamente valorado en la medicina tradicional china durante siglos. Según el Diccionario de Hongos [9], hay 100 especies conocidas de Cordyceps, y la base de datos del Index Fungorum del CABI tiene 506 entradas para este género. En China se conoce con los nombres de Hia tsao tong tchong o Dong Chong Xia Cao (chongcao) y en inglés como cordyceps mushroom o caterpillar fungus. No tiene nombre conocido en español al ser un hongo que no se encuentra en nuestro país y ser prácticamente desconocido. Desde 1980, cerca de 2.000 artículos científicos se han publicado acerca de Cordyceps sinensis (1.500 de ellos en chino) [6]. En este trabajo se hace un resumen de lo publicado con anterioridad en relación con este hongo: su hábitat, historia, comercialización y consumo, nomenclatura, composición farmacológica, cultivo y aplicaciones médicas.

Fern spores are unicellular structures produced by the sporophyte generation that give rise to the haploid gametophyte. When released from the sporangium, spores are desiccation tolerant (DT) in the royal fern (Osmunda regalis) and contain fully developed chloroplasts. As a consequence, this type of spores is called chlorophyllous spores (CS). Upon transfer to germination conditions, CS initiate a process of imbibition that suppresses DT in 72h, before the germination starts. In parallel to such change in DT, thylakoids undergo a profound remodelling in composition and function. Firstly, sustained quenching of chlorophyll fluorescence is relaxed, giving rise to photochemically active CS, while lipid composition shifts from that of a resting structure to a metabolically active cell. Basically trigalactolipids decreased in favour of monogalactolipids, with a parallel desaturation of fatty acids. Storage lipids such as triacylglycerol were quickly depleted. These results highlight the importance of the structure of thylakoids lipid as a key to protect membrane integrity during desiccation, together with the saturation of fatty acids and the constitutive chlorophyll quenching to prevent oxidative damage. The CS used here, in which the same cell shifts from DT to sensitive strategy in 72h, reveal their potential as unicellular models for future studies on DT.
