Structure and function of tomato leaf chloroplasts during ammonium toxicity.
Ammonium toxicity resulted in morphological modifications of tomato leaf chloroplasts. The chloroplasts, which are normally flattened around the protoplast periphery, became ellipsoidally rounded and dispersed through the protoplasm. The first apparent effect of plastid degradation was development of many vesicles from the fretwork. Later the grana lamellae swelled, and some disappeared. Eventu...
متن کاملStress - induced Ethylene Production in the Ethylene - requiring Tomato Mutant
Ethylene synthesis in vegetative tisues is thought to be controlled by indoleacetic acid (IAA). However, ethylene synthesis in the diageotropka (dgt) mutant of tomato (Ly mkoaesc MIlL) was much less sensitive to IAA than In the norml variety (VFNS). Yet, mehanial wounding stimuted ethyne production by the mutant. The dgt tomato provides an opportunity to study the regulation of stress ethylene ...
متن کاملAmmonium Toxicity and Potassium Limitation in Yeast
DNA microarray analysis of gene expression in steady-state chemostat cultures limited for potassium revealed a surprising connection between potassium and ammonium: potassium limits growth only when ammonium is the nitrogen source. Under potassium limitation, ammonium appears to be toxic for Saccharomyces cerevisiae. This ammonium toxicity, which appears to occur by leakage of ammonium through ...
