Characterization and Localization of a Phenoloxidase in Mung Bean Hypocotyl Cell Walls.

abstract：:A decline in growth, flowering, and boll (fruit) retention is referred to as cutout in cotton (Gossypium hirsutum L.). Fruit load affects cutout, possibly through hormonal effects. Experiments were conducted to test the hypothesis that fruits are a source of abscisic acid (ABA) that moves into fruiting branches and gr...
