L. plants are sensitive to water stress conditions throughout their life cycle from seed germination to seed setting. This study aims at identifying quantitative trait loci (QTL) linked to tolerance to water stress mimicked by applications of 10% polyethylene glycol-6000 (PEG-6000).

Over-expression of BnPgb2 elevated the amount of oil, which showed a positive relationship with the level of BnPgb2, without altering the oil nutritional value, as evidenced by the lack of major changes in composition of fatty acids (FA), and key agronomic traits.

Water stress, mimicked by applications of 10 % polyethylene glycol (PEG), elevates nitric oxide (NO) in root cells after a few hours, contributing to degradation of the root apical meristems (RAMs), the function of which relies on auxin and brassinosteroids (BRs). Phytoglobins (Pgbs) are effective NO scavengers induced by this stress.

Breeding of resistant cultivars containing race-specific resistance genes is provably effective to combat this disease. While two allelic resistance genes and recognizing avirulence genes and at plant apoplastic space have been cloned in , the downstream gene expression network underlying the resistance remains elusive.

() microspore-derived embryogenesis has become a model system to study basic aspects of plant development. Recognized transcription factors governing embryogenesis include: (), a member of the plant-specific B3-domain family, and (), a member of the HAP3 subunit of the CCAAT binding factor family. The effects of altered expression of both genes were investigated during microspore-derived embryogenesis in established lines over-expressing or down-regulating , as well as in tilling lines where was mutated.

Canola (Brassica napus L.) oil is extensively utilized for human consumption and industrial applications. Among the genes regulating seed development and participating in oil accumulation is FUSCA3 (FUS3), a member of the plant-specific B3-domain family of transcription factors.
