Inhibition by fusicoccin of germination of pea seeds.
Fusicoccin inhibits the germination of pea (Pisum sativum L. cv Progress 9) seeds by decreasing the growth of the embryonal axis and by stimulating the fresh weight increase of the cotyledons. The growth of isolated embryonal axes in the presence of sucrose and KCl is stimulated by fusicoccin. The effect of fusicoccin on the seeds is not counteracted by sucrose and KCl. Fusicoccin promotes pref...
متن کاملSALICYLIC ACID INHIBITION OF GERMINATION, ETHYLENE PRODUCTION AND RESPIRATION IN COCKLEBUR SEEDS
Salicylic acid (SA) inhibited germination of cocklebur (Xanthium pennsylvanicum Wlr), lower seeds, which are completely after-ripened and nondormant. SA also inhibited ethylene production during a pre-germination period of the seeds. Exogenous ethylene overcame the inhibtion of the seed germination by SA. Moreover, SA reduced respiration in pre-germinating whole seeds as well as excised axial...

متن کاملHexokinase II of Pea Seeds.
A second hexokinase (EC 2.7.1.1) was obtained from pea seed (Pisum sativum L. var. Progress No. 9) extracts. The enzyme, termed hexokinase II, had a high affinity (K(m), 48 micromolar) for glucose and a relatively low affinity (K(m), 10 millimolar) for fructose. The K(m) for MgATP was 86 micromolar. Mg(2+) was required for activity, but excess Mg(2+) was inhibitory. MgADP inhibited hexokinase I...
