Increasing salinity led to substantially higher ratios of mesophyll surface area to leaf area (A(mes)/A) for Phaseolus vulgaris and Gossypium hirsutum and a smaller increase for Atriplex patula, a salt-tolerant species. The increase in internal surface for CO(2) absorption did not lead to higher CO(2) uptake rates, since the CO(2) resistance expressed on the basis of mesophyll cell wall area (r...

3-Hydroxy-a-calacorene was identified in extracts from cold-shocked seedlings of cotton (Gossypium hirsutum L.) and kenaf (Hibiscus cannabinus L.), both of which are members of the Malvaceae family. ( )-3-Hydroxy-a-calacorene was isolated from Heterotheca inuloides Cass. (Asteraceae). HPLC on a chiral stationary phase column showed that the 3-hydroxy-acalacorene from cotton and kenaf had the sa...

This document provides a comprehensive review of the information and data relevant to the environmental risk assessment of Cry1F, a family of proteins encoded by genes isolated from Bacillus thuringiensis (Bt), and it presents a summary statement about the environmental safety of these proteins when produced in genetically engineered (GE) cotton (Gossypium hirsutum) and maize (Zea mays) plants....

The temperature at which cotton seeds (Gossypium hirsutum L.) germinated influenced the fatty acid composition of the polar lipids of developing root tips. Seeds were germinated at 15, 20, 25, and 30 C. As the temperature decreased the linolemic acid content of the polar lipid fraction increased. Sandoz 9785[4-chloro-5-(dimethylamino)-2-phenyl-3(2H)-pyridazinone] reduced the low temperature-ind...

Background and Rationale The scientific infrastructure in support of cotton research and improvement took a ‘giant leap forward’ with the release of the first ‘gold-standard’ cotton reference genome sequence on 5 January 2012. Later in 2012, two independent publications (Paterson et al. 2012; Wang et al. 2012) provided initial descriptions of the basic genome of cotton, with one of these also r...

The cotton plant (Gossypium hirsutum L.) has a very dynamic response to management and changes in the environment that often results in variable and unpredictable yields. Temperature plays a major role in the development of cotton yield. However, limited data are available describing the relationship between high temperature and cotton yield. In this study, it was hypothesized that there are nu...
