This work investigated the importance of the ability of leaf mesophyll cells to control K⁺ flux across the plasma membrane as a trait conferring tissue tolerance mechanism in plants grown under saline conditions. Four wheat (Triticum aestivum and Triticum turgidum) and four barley (Hordeum vulgare) genotypes contrasting in their salinity tolerance were grown under glasshouse conditions. Seven to 1 ...

Abstract:
... Alternative oxidase (AOX) constitutes a nonenergy conserving branch of the mitochondrial electron transport chain. AOX activity may be important to avoid reactive oxygen species (ROS) generation by the chain, particularly during abiotic stress. We compared leaf AOX1a transcript and AOX protein amounts in wild‐type (WT) Nicotiana tabacum plants experiencing mild to severe drought. Mild to moderate ...

Abstract:
... Endocarp developmental timing in drupe‐type fruits, involving tissue expansion and sclerification processes, is increasingly used as marker for biological studies and crop management. In spite of its wide application, however, little is known regarding how these morphogenetic processes unfold or the factors that modify it. This study evaluates endocarp expansion and sclerification of olive (Olea e ...

Abstract:
... Elevations of carbon dioxide, temperature and ultraviolet‐B (UBV) radiation in the growth environment may have a high impact on the accumulation of carbon in plants, and the different factors may work in opposite directions or induce additive effects. To detect the changes in the growth and phytochemistry of silver birch (Betula pendula) seedlings, six genotypes were exposed to combinations of amb ...

To date, almost no information is available in roots and shoots of the model plant Arabidopsis thaliana about the hierarchic relationship between metal accumulation, phytohormone levels, and glutathione/phytochelatin content, and how this relation affects root development. For this purpose, specific concentrations of cadmium, copper and zinc, alone or in triple combination, were supplied for 12 da ...

Abstract:
... Plants in the field are commonly exposed to fluctuating light intensity, caused by variable cloud cover, self‐shading of leaves in the canopy and/or leaf movement due to turbulence. In contrast to C₃plant species, only little is known about the effects of dynamic light (DL) on photosynthesis and growth in C₄plants. Two C₄and two C₃monocot and eudicot species were grown under steady light or DL con ...

Abstract:
... Light is the energy source for photosynthetic organisms but, if absorbed in excess, it can drive to the formation of reactive oxygen species and photoinhibition. One major mechanism to avoid oxidative damage in plants and algae is the dissipation of excess excitation energy as heat, called non‐photochemical quenching (NPQ). Eukaryotic algae and plants, however, rely on two different proteins for N ...

Abstract:
... Maximum photosynthesis rates in ferns are generally lower than those of seed plants, but little is known about the limiting factors, which are crucial to understand the evolution of photosynthesis in land plants. To address this issue, a gas exchange/chlorophyll fluorescence analysis was performed in three fern species spanning high phylogenetic range within Polypodiopsida (Osmunda regalis, Blechn ...

Abstract:
... The aspartate‐derived amino acid pathway in plants is an intensively studied metabolic pathway, because of the biosynthesis of the four essential amino acids lysine, threonine, isoleucine and methionine. The pathway is mainly controlled by the key regulatory enzymes aspartate kinase (AK; EC 2.7.2.4), homoserine dehydrogenase (HSDH; EC 1.1.1.3) and 4‐hydroxy‐tetrahydrodipicolinate synthase (EC 4.3. ...

To elucidate the functions of microRNA (miRNAs) and endogenous small‐interfering RNAs (siRNAs) in tomato fruit ripening process, the deep sequencing and bioinformatics methods were combined to parse the small RNAs landscape in three fruit‐ripening stages (mature gr ...

Abstract:
... Plant physiological and biochemical processes are significantly affected by gamma irradiation stress. In addition, gamma‐ray (GA) differentially affects gene expression across the whole genome. In this study, we identified radio marker genes (RMGs) responding only to GA stress compared with six abiotic stresses (chilling, cold, anoxia, heat, drought and salt) in rice. To analyze the expression pat ...

Abstract:
... NAC (NAM‐ATAF1, 2‐CUC2) family members play important roles in various environmental responses. Here, we cloned a full‐length NAC gene (954 bp) from Solanum lycopersicum (SlNAC1). This gene belonged to ATAF subfamily which included ATAF1 and ATAF2 of Arabidopsis thaliana. SlNAC1 expression was induced by chilling stress (4°C), heat stress (40°C), high salinity, osmotic stress and mechanical woundi ...
