متن کاملDifferential expression and internal feedback regulation of 1-aminocyclopropane-1-carboxylate synthase, 1-aminocyclopropane-1-carboxylate oxidase, and ethylene receptor genes in tomato fruit during development and ripening.
We investigated the feedback regulation of ethylene biosynthesis in tomato (Lycopersicon esculentum) fruit with respect to the transition from system 1 to system 2 ethylene production. The abundance of LE-ACS2, LE-ACS4, and NR mRNAs increased in the ripening fruit concomitant with a burst in ethylene production. These increases in mRNAs with ripening were prevented to a large extent by treatmen...
متن کاملEffect of 1-Methylcyclopropene on Antioxidant Activity and Gene Expression of Acc-Synthase and Acc-Oxidase in Cotton Flowers
Cotton yields in the Mid-south are well below the theoretical potential (Baker and Hesketh, 1969). Low and variable cotton yields have been associated with environmental stress, of which temperature and drought appear to play the major role. When plants are stressed they produce ethylene, a plant growth regulator known to cause various plant physiological responses, including control fruit absc...
متن کاملCharacterization of 1-aminocyclopropane-1-carboxylate (ACC) oxidase in broccoli florets and from Escherichia coli cells transformed with cDNA of broccoli ACC oxidase
During senescence of broccoli (Brassica oleracea L. var. italica) florets (flower buds), the rate of ethylene production increased, almost paralleling the rapid increase in 1-aminocyclopropane-1-carboxylate (ACC) oxidase activity. The increase in ACC oxidase activity was strongly suppressed by the administration of cycloheximide, suggesting that it may have resulted from the de novo synthesis o...
متن کاملDifferentiation of 1-aminocyclopropane-1-carboxylate (ACC) deaminase from its homologs is the key for identifying bacteria containing ACC deaminase.
1-Aminocyclopropane-1-carboxylate (ACC) deaminase-mediated reduction of ethylene generation in plants under abiotic stresses is a key mechanism by which bacteria can promote plant growth. Misidentification of ACC deaminase and the ACC deaminase structure gene (acdS) can lead to overestimation of the number of bacteria containing ACC deaminase and their function in ecosystems. Previous non-speci...
