LTR retrotransposons (LTR-RTNs) are widespread constituents of eukaryote genomes, particularly plant genomes. Although LTR-RTNs from plants were thought to be transcriptionally silent in somatic tissues, evidences of activity under certain conditions are available for some of them. In order to

Oleocellosis, a physiological rind disorder of citrus fruit, is an unattractive surface blemish caused by phytotoxic effects of released rind oils. The development of oleocellosis in Washington navel orange (Citrus sinensis L. Osbeck) was examined by following a time sequence of surface symptoms and

Flowering and flower formation are defining features of angiosperms and the control of these developmental processes involves a common repertoire of genes which are shared among different species of flowering plants. These genes were first identified using various homeotic and flowering time mutants

Flavonoid and limonoid glycosides influence taste properties as well as marketability of Citrus fruit and products, particularly grapefruit. In this work, nine grapefruit putative natural product glucosyltransferases (PGTs) were resolved by either using degenerate primers against the semiconserved

Citrus fruit is prone to develop peel pitting during development and storage, which greatly decreases its fresh market value because of the deterioration of the peel. In the present study, we have examined the effect of different temperatures (15 degrees C and 4 degrees C), waxing and mechanical

A study was conducted to standardize the technology for the removal of amino acids (one of the browning reaction substrates) from sweet orange cv. Malta Common juice to reduce colour and quality deterioration in single strength juice and during subsequent concentration. Juice of sweet orange (Citrus

Pectin methyl esterase (PME) from orange (Citrus sinensis L.) fruit peels has been purified by ammonium sulphate precipitation, and ion-exchange and gel-filtration chromatography. Characterization of the enzyme revealed a 36-kDa protein with an isoelectric point > 9, a pH optimum at 7 and

We report on the isolation, functional expression and characterization of a cDNA encoding chlorophyllase, the enzyme catalyzing the first step in the chlorophyll breakdown pathway. The Chlase1 cDNA from Valencia Orange (Citrus sinensis cv. Valencia) was obtained by RT-PCR using degenerate primers

The role of photosynthesis in plant defense is a fundamental question awaiting further molecular and physiological elucidation. To this end we investigated host responses to infection with the bacterial pathogen Xanthomonas axonopodis pv. citri, the pathogen responsible for citrus canker. This

Naturally, resistant crop germplasms are important resources for managing the issues of agricultural product safety and environment deterioration. We found a spontaneous mutant of 'Newhall' navel orange (Citrus sinensis Osbeck) (MT) with broad-spectrum protections against fungal pathogens in the
