Enhancement of Nitrate Reductase Activity by Benzyladenine in Agrostemma githago.
Nitrate reductase activity in excised embryos of Agrostemma githago increases in response to both NO(3) (-) and cytokinins. We asked the question whether cytokinins affected nitrate reductase activity directly or through NO(3) (-), either by amplifying the effect of low endogenous NO(3) (-) levels, or by making NO(3) (-) available for induction from a metabolically inactive compartment. Nitrate...
متن کاملProtein Synthesis in Embryos of Dormant and Germinating Agrostemma githago L. seeds.
The time course of protein synthesis in embryos of dormant and afterripened Agrostemma githago seeds was studied. In embryos of afterripened geminating seeds, protein synthesis increased in three successive stages: (a) concurrent with swelling; (b) during the lag phase between the completion of water uptake and the onset of growth; and (c) immediately after protrusion through the seed coat. Emb...

متن کاملEnvironmental conditions during early life determine the consequences of inbreeding in Agrostemma githago (Caryophyllaceae).
In an inbred population, selection may reduce the frequency of deleterious recessive alleles through a process known as purging. Empirical studies suggest, however, that the efficacy of purging in natural populations is highly variable. This variation may be due, in part, to variation in the expression of inbreeding depression available for selection to act on. This experiment investigates the ...
متن کاملAssembly of Agrostemma githago (corn-cockle) storage proteins and their precursor proteins into oligomers.
The major fraction of seed storage proteins of Agrostemma githago (corn-cockle), a non-leguminous dicot, occurs as material with S20,w values of approximately 11S and approximately 2S, and a minor fraction as oligomers with S20,w values of approximately 6.5S. The 11S proteins are of the legumin type and consist of disulphide-linked alpha- and beta-subunits of Mr approximately 39 000 and approxi...
