Hormonal Regulation of alpha-Amylase Gene Transcription in Wild Oat (Avena fatua L.) Aleurone Protoplasts.
The time of appearance and relative amounts of alpha-amylase mRNA in wild oat (Avena fatua L.) aleurone protoplasts incubated with 1 micromolar gibberellin A(4) (GA(4)) were closely correlated with the amounts of alpha-amylase enzyme secreted by the protoplasts. In the absence of GA(4), or when protoplasts were incubated with 25 micromolar abscisic acid (ABA) together with 1 micromolar GA(4) no...
متن کاملPlant growth and phenolic compounds in the rhizosphere soil of wild oat (Avena fatua L.)
The objectives of this study were to determine the pattern of dry matter (DM) accumulation and the evolution of phenolic compounds in the rhizosphere soil from tillering to the ripe seed stages of wild oat (Avena fatua L.), a widespread annual grassy weed. Plants were grown under controlled conditions and harvested 13 times during the growing season. At each harvest, shoot and root DM and pheno...
متن کاملCharacterisation of Avena fatua populations with resistance to multiple herbicides
Avena fatua (wild oat) populations with resistance (R) to one or more herbicides have been described in numerous cropping systems worldwide. We previously reported that the R3 and R4 wild oat populations from Montana, USA, were resistant to four herbicides representing three different modes of action: tralkoxydim [acetyl-CoA carboxylase (ACCase] inhibitor), imazamethabenz and flucarbazone [acet...
متن کاملImpact of Biotic and Abiotic Stresses on the Competitive Ability of Multiple Herbicide Resistant Wild Oat (Avena fatua)
Ecological theory predicts that fitness costs of herbicide resistance should lead to the reduced relative abundance of resistant populations upon the cessation of herbicide use. This greenhouse research investigated the potential fitness costs of two multiple herbicide resistant (MHR) wild oat (Avena fatua) populations, an economically important weed that affects cereal and pulse crop productio...
متن کاملEarly Actions of Gibberellic Acid on the Embryo and on the Endosperm of Avena fatua Seeds.
Gibberellic acid at 0.1 mum stimulates amylase synthesis in dormant Avena fatua seeds without inducing germination; at 0.5 mm it enhances biosynthesis of proteins and RNA in both the embryo and the endosperm and utilization of the endosperm sugars by the embryo. These events occur in early hours (0-14th hour) and prior to germination, which begins 24 hours after gibberellic acid application. Th...
