Spodoptera exigua modulates gossypol biosynthesis in cotton Gossypium hirsutum
Cotton plants induce high levels of gossypol in response to herbivore damage. However, little is known about the mechanisms by which insect herbivory modulates gossypol biosynthesis in cotton plants. Here, we report the mechanism by which herbivore damage or insect-originated elicitors modulate the biosynthesis of gossypol and jasmonic acid (JA) in plants. Spodoptera exigua larval-damaged (HD) ...
متن کاملLowering seed gossypol content in glanded cotton (Gossypium hirsutum L.) lines
Cottonseed is a rich source of high quality protein, but its value as an animal feed is limited by gossypol, a toxic polyphenolic compound contained in glands located throughout the plant. This compound helps protect the plant from pests. Totally glandless varieties have been developed, but not adopted as these plants are left vulnerable to pests. This study describes a breeding strategy to dec...
متن کاملBreeding and genetics Modifying gossypol in cotton (Gossypium hirsutum L.): a cost effective Method for small seed samples
cotton (Gossypium hirsutum L.) and related species all contain gossypol, a polyphenolic compound that is an integral part of the cotton plant’s self-defense system against insect pests and possibly some diseases. gossypol also has been reported to have antitumor activity, medicinal effects, and contraceptive properties. However, the compound can be toxic to animals, which limits the usefulness ...
متن کاملIn vitro Plant Regeneration from the Callus of Shoot Tips in Cotton (Gossypium hirsutum L. cv. SVPR 2)
A high efficiency shoot organogenesis from callus cultures and plant establishment protocol has been developed for cotton (Gossypium hirsutum L. cv SVPR-2) through shoot tip. After 6 weeks of culture, green-compact-nodular organogenic callus induction was observed on the medium fortified with (MS) basal salts, B5 vitamins, 2.0 mgl-1 of benzylaminopurine (BAP), 1.0 mgl-1 kinetin (KN), 30 gl-1 gl...
متن کاملInfraspecific DNA methylation polymorphism in cotton (Gossypium hirsutum L.).
Cytosine methylation is important in the epigenetic regulation of gene expression and development in plants and has been implicated in silencing duplicate genes after polyploid formation in several plant groups. Relatively little information exists, however, on levels and patterns of methylation polymorphism (MP) at homologous loci within species. Here we explored the levels and patterns of met...
