Objectives: (1) Obtain complete genomic clones plus promoter regions of apple peel genes encoding HMGR isozymes HMG2 and HMG3 and determine whether expression of these genes is regulated by ethylene; (2) Demonstrate function of the gene product and obtain a genomic clone of the ethyleneresponsive promoter of the putative apple α-Farnesene Synthase gene; (3) Determine correlation among ethylene-...

The coffee berry borer, Hypothenemus hampei (Ferrari), continues to pose a formidable challenge to coffee growers worldwide. Because of the cryptic life habit of the insect inside coffee berries, effective pest management strategies have been difficult to develop. A sesquiterpene, (E,E)-α-farnesene, produced by infested coffee berries has been identified as a potential repellent against the cof...

Fresh jasmine flowers have been used to make jasmine teas in China, but there has been no complete information about volatile organic compound emissions in relation to flower developmental stages and no science-based knowledge about which floral stage should be used for the infusion. This study monitored volatile organic compounds emitted from living flowers of Jasminum sambac (L.) Ait. 'Bifoli...

Superfi cial scald of apples and pears, which manifests as brown or black patches on the fruit skin, results from necrosis of the hypodermal cortical tissue (Bain and Mercer, 1963) and is thought to be induced by oxidation products of the sesquiterpene (E,E)-α-farnesene (Anet, 1972a; Huelin and Coggiola, 1970a, 1970b; Huelin and Murray, 1966). Synthesis of sesquiterpenes in plant tissues occurs...

background: it was found that, climatic conditions and fruit ripeness are important factor for the occurrence and intensity of superficial scald. 1-mcp is an inhibitor of ethylene action in plants and inhibits many ripening related processes along with the production of ethylene and volatiles. objective: apples are often held for several months at low temperature either in air (ra) or in contro...
