The peroxidase (POD) family shows functional diversity. Luo et al. demonstrate that Brachypodium distachyon ecotypes have distinct specific POD isozymes.
Two POD genes are closely associated with whole-plant response to drought, which may lead to natural variations of drought tolerance. The role of specific POD genes in differentiating Brachypodium accessions with contrasting drought tolerance could be associated with the general fitness of Brachypodium distachyon during evolution.
Most plants acquire nitrogen from the soil in the form of nitrate (NO3−) or ammonium (NH4+). Ammonium-based nutrition is gaining interest because it helps to avoid environmental concerns associated with nitrate...
Some polyploid species show enhanced physiological tolerance to drought compared with their progenitors. However, very few studies have examined the consistency of physiological drought response between genetically...
Cold treatment accelerates the transition from the vegetative to the reproductive phase in seven Brachypodium distachyon accessions.
