“…Producing longer and stronger fiber with a suitable micronaire is important to market preference (Mishra et al, 2001), however, declining temperature and low light caused by cloudy, overcast and rainy weather during cotton flowering and boll formation in the Yangtze River Valley can have an adverse affect on fiber quality, and the genotype fiber quality potential is not fully realized (Bradow and Davidonis, 2010). In this study, fiber length, strength and Micronaire values were significantly affected by cultivar, planting date and/or shading treatment (P < 0.05, Table 5), which were identical with the trends of fiber biomass and cellulose accumulation ( Figs.…”

“…Fibre development is restricted by declining temperature or low light in many cotton-grown areas (Dong et al 2006;Wang et al 2005Wang et al , 2006Yeates et al 2010), and the two climatic conditions often appear as a combined factor during the periods of flowering and boll development of cotton, e.g., in the Yangtze River Valley, cotton often suffers from rainy and overcast weather during the early stages of flowering and boll formation, and is also affected by the declining temperatures accompanying the cloudy and overcast weather at the later stages. The sub-optimal environmental conditions during the fibre elongation phase may decrease the rate of elongation per day or shorten the duration of the elongation period, so that the genotype fibre length potential is not fully realised (Hearn 1976;Bradow and Davidonis 2010;Zhao et al 2012). Therefore, it is important to understand the mechanisms of the interactive effects of declining temperature and low light on cotton fibre elongation.…”

Declining temperature and low light often appear together to affect cotton (Gossypium hirsutum L.) growth and development. To investigate the interaction on fibre elongation, two cultivars were grown in fields in 2010 and 2011 and in pots in 2011 under three shading levels for three planting dates, and the differences of environmental conditions between different planting dates were primarily on temperature. Fibre length in the late planting date 25 May was the longest instead of the normal planting date. Late planting prolonged fibre elongation period and the effect of late planting on fibre length formation was greater than low light. In the normal planting date, shading increased fibre length through delaying the peak of b-1,3-glucanase gene expression and bringing the peak of b-1,3-glucan synthase gene expression forward, leading to a longer duration of plasmodesmata(PD) closure to increase fibre length, instead of changing sucrose contents or relate enzyme activities. However, in the late planting dates, the difference of the duration of PD closure between shading treatments was not obvious, but low light had a negative impact on sucrose contents, sucrose synthase (SuSy) and vacuolar invertase(VIN) activities during fibre rapid elongation period, leading to the decline of fibre length. Due to late planting and low light, the decreased extent of fibre length of Sumian 15 was larger than Kemian 1. Under the combined condition, Sumian 15 had a shorter gene expression of Expansin, and more sensitive sucrose content, VIN and SuSy activity during fibre rapid elongation period. This resulted in the length formation of Sumian 15 which was more sensitive than Kemian 1, when the cotton suffered the combined effects.

“…However, as water deficit stress progressively continues, development and reproduction of cotton is severely affected, and the quality and yield of cotton fiber production is significantly reduced [25,26]. Therefore, for successful cotton fiber production, it is essential to understand proper management strategies between water demand, irrigation, and plant responses that are seasonally variable [27].…”

BackgroundCotton is the world’s primary fiber crop and is a major agricultural commodity in over 30 countries. Like many other global commodities, sustainable cotton production is challenged by restricted natural resources. In response to the anticipated increase of agricultural water demand, a major research direction involves developing crops that use less water or that use water more efficiently. In this study, our objective was to identify differentially expressed genes in response to water deficit stress in cotton. A global expression analysis using cDNA-Amplified Fragment Length Polymorphism was conducted to compare root and leaf gene expression profiles from a putative drought resistant cotton cultivar grown under water deficit stressed and well watered field conditions.ResultsWe identified a total of 519 differentially expressed transcript derived fragments. Of these, 147 transcript derived fragment sequences were functionally annotated according to their gene ontology. Nearly 70 percent of transcript derived fragments belonged to four major categories: 1) unclassified, 2) stress/defense, 3) metabolism, and 4) gene regulation. We found heat shock protein-related and reactive oxygen species-related transcript derived fragments to be among the major parts of functional pathways induced by water deficit stress. Also, twelve novel transcripts were identified as both water deficit responsive and cotton specific. A subset of differentially expressed transcript derived fragments was verified using reverse transcription-polymerase chain reaction. Differential expression analysis also identified five pairs of duplicated transcript derived fragments in which four pairs responded differentially between each of their two homologues under water deficit stress.ConclusionsIn this study, we detected differentially expressed transcript derived fragments from water deficit stressed root and leaf tissues in tetraploid cotton and provided their gene ontology, functional/biological distribution, and possible roles of gene duplication. This discovery demonstrates complex mechanisms involved with polyploid cotton’s transcriptome response to naturally occurring field water deficit stress. The genes identified in this study will provide candidate targets to manipulate the water use characteristics of cotton at the molecular level.
