“…Field experiments were conducted at Jiangsu Academy of Agricultural Sciences in 2009, and at the Pailou experimental station in 2010 and 2011, Nanjing (118°50 0 E, 32°02 0 N), Jiangsu, China, using two cotton cultivars, Kemian 1 (cool temperature-tolerate) and Sumian 15 (cool temperature-sensitive) (Liu et al 2013;Shu et al 2009), which are widely cultivated in the Yangtze River Valley, China. The soil at the experimental site was clay, mixed, thermic, Typic Udalfs, Alfisols with 18.3 and 18.5 g kg -1 organic matter, 1.1 and 1.0 g kg -1 total N, 65 and 81 mg kg -1 mineral N (NH 4 ?…”

To investigate the photosynthetic characteristics in the subtending leaf of cotton (Gossypium hirsutum L.) boll (LSCB), and their relationships with lint yield and fiber quality under cool temperature due to late planting, field experiments during 2009 to 2011 were conducted using two different cool temperature-tolerant cultivars, Kemian 1 (temperature-tolerate) and Sumian 15 (temperature-sensitive), at three planting date (25 April, 25 May and 10 June) in Nanjing (118°50 0 E, 4 32°02 0 N), China. First, the chlorophyll components in LSCB decreased with days post-anthesis, as well as soluble sugar content, amino acid content and C/N ratio. In addition, Pn, U PS II and F v / F m significantly decreased, indicating that Pn depression in LSCB was due to non-stomata closure. Second, under cool temperature due to late planting (from 25 April to 25 May and/or 10 June), Pn depression was due to stomata closure. Compared to Sumian 15, Kemian 1 demonstrated superior photosynthetic capacity. Furthermore, under cool temperature, lint biomass and seed biomass significantly decreased in parallel with the lint distribution rate, seed distribution rate and lint/seed ratio, whereas carpel distribution rate increased. These changes under cool temperature led to low lint yield and fiber strength. According to CVs and variance among three planting dates, Sumian 15 was more sensitive to cool temperature than Kemian 1.

“…The enzymology of fibre elongation and cellulose synthesis metabolism were conducted in plants using only a single factor of cool temperature or low light (Martin and Haigler 2004;Bian et al 2008;Shu et al 2009); there is limited research about the response of key enzymes in cotton fibre elongation to the combined effects. This research was designed to study the interaction of late planting and low light on related enzyme activities and gene expressions of expansin, b-1,3-Gluc, b-1,3-glucS, SuSy and VIN in fibre elongation and sucrose metabolism.…”

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.

“…As one of the main outcomes of plant photosynthesis, sucrose is influenced by activities of metabolism-related enzymes (Artuso et al 2000;Shu et al 2009). A previous study reported that the inhibition of SPS activity decreased the rate of sucrose synthesis in plants following exposure to chilling temperature (Van Heerden et al 2004).…”

Introduction: Understanding how mangroves respond to rare cold events has implications for both restoration and conservation under climate change scenarios. This study investigated the responses of photosynthesis and activities of key enzymes involving carbon and nitrogen metabolism at different ages of Kandelia obovata to a rare cold event in the winter of 2010. Methods: This study took place on Ximen Island, Zhejiang Province, China. We measured the physiological recovery of 2-3-, 5-6-, 9-10-and 54-55-year-old K. obovata trees after freezing injury in February and March in 2011 and 2012, respectively. Results: Chilling injury index and electrolyte leakage of K. obovata increased with increasing tree age in the winter of 2010, and electrolyte leakage in K. obovata at different ages in the winter of 2010 was far higher than that in the winter of 2011. The rare cold events significantly changed the recoveries of the leaf net photosynthetic rate (Pn) and stomatal conductance (Gs); ratios of chlorophyll a/chlorophyll b (Chl a/Chl b); contents of total soluble sugar (TSS), sucrose, free amino acid (FAA), and soluble protein; and activities of sucrose phosphate synthase (SPS), endopeptidase, and carboxypeptidase in K. obovata at different ages. These effects were mainly due to changes in the physiological mechanism in the 2-year-old trees. A clear decrease in Pn of the 2-year-old trees was observed in February 2011, as exemplified by reductions in ratios of Chl a/Chl b and chlorophyll/carotenoid (Chl/Car), as well as inhibition of the levels of TSS and FAA (osmotic substances). During recovery in 2011 and 2012, the activities of SPS and sucrose synthase (SS) were responsible for sucrose synthesis after the rare cold events in 2011, but only SPS activity was one of the main factors contributing to the metabolism of stachyose to sucrose without cold damage in 2012. Carboxypeptidase played a more important role than endopeptidase during protein hydrolysis after the rare cold events.
