The SWEET (sugars will eventually be exported transporters) proteins are sugar efflux transporters containing the MtN3_saliva domain, which affects plant development as well as responses to biotic and abiotic stresses. These proteins have not been functionally characterized in the tetraploid cotton, Gossypium hirsutum, which is a widely cultivated cotton species. In this study, we comprehensive...

Cotton is one of the major world oil crops. Cottonseed oil meets the increasing demand of fried food, ruminant feed, and renewable bio-fuels. MADS intervening keratin-like and C-terminal (MIKC)-type MADS-box genes encode transcription factors that have crucial roles in various plant developmental processes. Nevertheless, this gene family has not been characterized, nor its functions investigate...

The red leaf coloration of Empire Red Leaf Cotton (ERLC) (Gossypium hirsutum L.), resulted from anthocyanin accumulation in light, is a well known dominant agricultural trait. However, the underpin molecular mechanism remains elusive. To explore this, we compared the molecular biological basis of anthocyanin accumulation in both ERLC and the green leaf cotton variety CCRI 24 (Gossypium hirsutum...

Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...

Yield variability in cotton (Gossypium hirsutum L.) from year to year in different environments (geographical locations) is a major production problem for farmers (Oosterhuis, 00 ). Higher yields have been recorded in the drier environment of California, compared to the more humid environment of Arkansas. However, the effect of environmental factors, such as temperature, relative humidity, and ...

Transgenic cotton (Gossypium hirsutum L.) with Bacillus thuringiensis Berliner δ-endotoxin genes has been widely adopted for suppression of lepidopteran pests. To account for inconsistency of the endotoxin gene expression, we developed a polymerase chain reaction (PCR) for checking the purity of transgenic cotton plants. A total of eight cry1Ac genes were aligned for the PCR primer design. A DN...

The unpredictability of cotton yields is a great concern to the cotton industry. High temperatures are considered to be one of the main environmental factors contributing to variable yields in cotton (Gossypium hirsutum L.). This has been attributed to a negative effect on respiration and carbohydrate accumulation, but the evidence for this is lacking. In this study it was hypothesized that hig...

BACKGROUND Upland cotton, Gossypium hirsutum L., is one of the world's most important economic crops. In the absence of the entire genomic sequence, a large number of expressed sequence tag (EST) resources of upland cotton have been generated and used in several studies. However, information about the flower development of this species is rare. METHODOLOGY/PRINCIPAL FINDINGS To clarify the mo...

Green cotton (Gossypium hirsutum L.) fibers were shown by electron microscopy to have numerous thin concentric rings around the lumen of the cell. These rings possessed a lamellar fine structure characteristic of suberin. LiA1D(4) depolymerization and gas chromatography-mass spectrometry analysis showed the presence of a suberin polymer in the green cotton with the major aliphatic monomers bein...
