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) ...

Lowering 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...

Gossypol biosynthesis in cotton revealed through

21 Gossypol plays an important role in defense mechanism of Gossypium species and the 22 presence of gossypol also limits the utilization of cottonseeds. However, little is 23 known about the metabolism of gossypol in cotton plant. Here, Detection on the 24 dynamic tendency of gossypol content illustrated that at the germination stage, the 25 main source of gossypol was cotyledon, and at the la...

Transformation of Gossypium hirsutum and Gossypium barbadense by Rhizobium rhizogenes: Hairy root induction and gossypol production

Responses of Three Successive Generations of Beet Armyworm, Spodoptera exigua, Fed Exclusively on Different Levels of Gossypol in Cotton Leaves

The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is an important pest of numerous crops, and it causes economic damage in China. Use of secondary metabolic compounds in plants is an important method used to control this insect as a part of integrated pest management. In this study the growth, development, and food utilization of three successive generations of S. exigua f...
