Respiration and Protein Synthesis in Dormant and After-ripened Seeds of Avena fatua.
Dormant seeds of Avena fatua, which do not germinate when allowed to imbibe water, have a respiration rate only about 20% less than that of imbibed nondormant (after-ripened) seeds in the period before actual germination and are capable of synthesizing protein at a rate comparable to that of the nondormant seeds. An increase of protein synthesis is observed in nondormant seeds at the beginning ...
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...
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 کاملMitochondrial Proteome Studies in Seeds during Germination.
Seed germination is considered to be one of the most critical phases in the plant life cycle, establishing the next generation of a plant species. It is an energy-demanding process that requires functioning mitochondria. One of the earliest events of seed germination is progressive development of structurally simple and metabolically quiescent promitochondria into fully active and cristae-conta...
متن کاملChanges in the Metabolism of Lipids and Carbohydrates during Germination of Sesame (sesamum Indicum L.) Seeds
The levels of lipids, carbohydrates and enzymes concerned with their breakdown were determined in sesame (Sesamum indicum L.) seeds during an 8-days period of germination. Alkaline lipase and isocitrate lyase activities were at peak level when the lipid mobilization was highest. The content of total soluble carbohydrates, reducing and nonreducing sugars, increased during the initial 5-days peri...
