Expression of the sesame MYB transcription factor SiMYB305 boosts tolerance to drought and salt stress in Arabidopsis

Improving crop tolerance to environmental stresses is of paramount importance to global food security. To protect themselves from abiotic stress, plants translate...

The SAUR41 subfamily of genes is involved in cell expansion and salt tolerance

The SAUR41 genes are ABA inducible and active during seedling establishment.

Strigolactones interact with other plant hormones in many situations

Strigolactones are interesting phytohormones in their own right, but Luke Omoarelojie and colleagues say we should be looking at cross-talk with other hormones too.

Potential involvement of root auxins in drought tolerance by modulating nocturnal and daytime water use in wheat

The ability of wheat genotypes to save water by reducing their transpiration rate (TR) at times of the day with high vapour pressure deficit...

Abscisic acid (ABA) and low temperatures increase cold-hardiness in grapevine dormant buds

It has been reported that low temperatures and the plant hormone abscisic acid (ABA) induce the expression of CBF/DREB1 transcription factors in vegetative tissues...

Responses of Eucalyptus globulus to eleven levels of continuous water availability

Foliar concentrations of plant secondary metabolites (PSMs) are influenced by soil water availability. However, concentrations of individual compounds in previously published studies have been...

Aquaporin function and exogenous application of abscisic acid (ABA) to barley roots

Using an immunochemical approach to reveal the link between changes in abscisic acid (ABA) levels, aquaporin function and changes in root cell hydraulic conductivity...

Within-species responses to water deficit vary more with traits than provenance

Plants manage water stress through various mechanisms, including increasing concentrations of compounds such as abscisic acid (ABA) to signal stomatal closure and reduce water...

Abscisic acid and seed development in a lady’s slipper orchid

Abscisic acid concentration and distribution during seed development of Cypripedium formosanum serves as the key inhibitor of germination.

Arabidopsis Mob1 gene regulates organ development

Mob1 proteins are kinase regulators that are conserved among eukaryotes and which play a significant role in restraining tumor development. Pinosa et al. study...

Plasticity to drought and ecotypic differentiation in populations of a crop wild relative

Plant functional traits often vary across space, particularly when species encounter contrasting environmental conditions throughout their range. Such phenotypic variation is determined...

Botanists Pull Apart the Genes of Bananas to See How They Came Together

Banana genes reveal how they may have passed through other hybrid stages.

Sympatric moss populations can form true hybrid zones

Hybridization between species has not been considered an important factor in the evolution of mosses. The moss life cycle has led many...

A key protein may help trigger germination in Arabidopsis seeds

Seed germination is a critical step in the life cycle of flowering plants. Since seeds contain limited reserves, seed germination has to...
