Abstract:
... Mining of an EST sequence collection representing genes expressed during seed development in Physaria fendleri identified abundant sequences encoding apparent homologues of the Arabidopsis oleate 12-desaturase (AtFAD2 At3g12120). Of the 62 sequenced clones, 59 were identified as encoding the previously characterized bifunctional oleate 12-hydroxylase/desaturase (LFAH12/PfFAH12). The remaining 3 cl ...

Abstract:
... The non-specific lipid transfer proteins (nsLTPs) are characterized by a compact structure with a central hydrophobic cavity very suitable for binding hydrophobic ligands, such as lipids. The nsLTPs are encoded by large gene families in all land plant lineages, but seem to be absent from green algae. The nsLTPs are classified to different types based on molecular weight, sequence similarity, intro ...

Abstract:
... The unicellular green alga Chlamydomonas reinhardtii has long served as model organism for studies on the circadian clock. This clock is present in all eukaryotes and some prokaryotes allowing them to anticipate and take advantage of the daily oscillations in the environment. Although much is known about the circadian clock in C. reinhardtii, the photoreceptors mediating entrainment of the clock t ...

Drought can activate several stress responses in plants, such as stomatal closure, accumulation of cuticular wax and ascorbic acid (AsA), which have been correlated with improvement of drought tolerance. In this study, a novel MYB gene, designed as EsWAX1, was isolated and characterized from Eutrema salsugineum. EsWAX1 contained a full-length open reading frame (ORF) of 1068 bp, which encoding 355 ...

Abstract:
... In plants, glutathione serves as a versatile redox buffer and cellular protective compound against a range of biotic and abiotic stresses. Glutathione production involves glutamate-cysteine ligase (GCL), the redox-regulated limiting enzyme of the pathway, and glutathione synthetase (GS). Because the sub-cellular and sub-organellar localization of these enzymes will have an impact on metabolism, he ...

Abstract:
... RALF is a small (5 kDa) and ubiquitous plant peptide signal. It was first isolated from tobacco leaf protein extracts owing to its capacity to alkalinize the extracellular media of cell suspensions. RALFs inhibit root growth and hypocotyl elongation, and a role for RALFs in cell expansion has also been proposed. Arabidopsis has 37 RALF isoforms (AtRALF), but only a small group of nine has high pri ...

Abstract:
... Arbuscular mycorrhizal (AM) fungi play a key role in the nutrition of many land plants. AM roots have two pathways for nutrient uptake, directly through the root epidermis and root hairs and via AM fungal hyphae into root cortical cells, where arbuscules or hyphal coils provide symbiotic interfaces. Recent studies demonstrated that the AM symbiosis modifies the expression of plant transporter gene ...
