Acid phosphatase activity in plastids (plastolysomes) of senescing embryo-suspensor cells.

abstract：:To study the interdependence of sucrose accumulation and its hydrolyzing enzyme, soluble acid invertase (AI; EC 3.2.1.26), in fructan-accumulating temperate grasses and cereals, experiments were performed in which sucrose synthesis was abolished in leaves of Lolium temulentum by four independent inhibitory factors, ea...
