Kiwifruit [Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson, cv. "Hayward"] is classified as climacteric fruit and the initiation of endogenous ethylene production following harvest is induced by exogenous ethylene or chilling exposure. To understand the biological basis of this "dilemma," kiwifruit ripening responses were characterized at 20°C following treatments with exogenous ethy...

Ethylene production by locule gel tissue excised from immature tomato fruit was inhibited by exposure to 4.5 mmol l C2H4, and 1-aminocyclopropane-1-carboxylic acid (ACC) content was reduced. In contrast, CO2 production, ethylene forming capacity (EFC), red colour development, tissue liquefaction and seed maturation as measured by subsequent germination rate were stimulated by C2H4, and, in imma...

Ethylene is one of the classical plant hormones with a diverse function in plant growth and development. Root elongation is sensitive to ethylene such that treatments with ethylene and the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) inhibit root growth. MicroRNA as one type of endogenous, non-coding small RNAs, plays an important role in regulation of plant growth, developmen...

HCN is the putative product of C-1 and amino moieties of 1-aminocyclopropane-1-carboxylic acid (ACC) during its conversion to ethylene. In apple (Malus sylvestrus Mill.) slices or auxin-treated mungbean (Vigna radiata L.) hypocotyls, which produced ethylene at high rates, the steady state concentration of HCN was found to be no higher than 0.2 micromolar, which was too low to inhibit respiratio...

The effect of light and CO(2) on both the endogenous and 1-aminocyclopropane-1-carboxylic acid (ACC)-dependent ethylene evolution from metabolically active detached leaves and leaf discs of Gomphrena globosa L. is reported. Treatment with varying concentrations of ACC did not appear to inhibit photosynthesis, respiration, or stomatal behavior. In all treatments, more ethylene was released into ...

Abstract Chickpea ( Cicer arietinum ), one of the major pulse crops in India, endured extreme reduction production due to various abiotic and biotic stresses. Endophytic bacteria residing nodules roots chickpea plants enable host combating these Twenty endophytic isolated from were screened for multiple plant growth promoting traits like ammonia, organic acid, siderophore, hydrogen cyanide (HCN...

The ripening of many fruits is controlled by an increase in ethylene hormone concentration. E8 is a fruit ripening protein that is related to the enzyme that catalyzes the last step in the ethylene biosynthesis pathway, 1-aminocyclopropane-1-carboxylic (ACC) oxidase. To determine the function of E8, we have transformed tomato plants with an E8 antisense gene. We show here that the antisense gen...
