“…It has been documented that SuSy, AI, and SPS are the critical enzymes involved in sucrose metabolism [50] [51] . In our study, we observed that these enzymes were affected by the FP effect, which might be the reason why sucrose transformation and cellulose synthesis in cotton fiber were restrained on distal FPs (e.g.…”

Cotton (Gossypium hirsutum L.) boll positions on a fruiting branch vary in their contribution to yield and fiber quality. Fiber properties are dependent on deposition of cellulose in the fiber cell wall, but information about the enzymatic differences in sucrose metabolism between these fruiting positions is lacking. Therefore, two cotton cultivars with different sensitivities to low temperature were tested in 2010 and 2011 to quantify the effect of fruit positions (FPs) on fiber quality in relation to sucrose content, enzymatic activities and sucrose metabolism. The indices including sucrose content, sucrose transformation rate, cellulose content, and the activities of the key enzymes, sucrose phosphate synthase (SPS), acid invertase (AI) and sucrose synthase (SuSy) which inhibit cellulose synthesis and eventually affect fiber quality traits in cotton fiber, were determined. Results showed that as compared with those of FP1, cellulose content, sucrose content, and sucrose transformation rate of FP3 were all decreased, and the variations of cellulose content and sucrose transformation rate caused by FPs in Sumian 15 were larger than those in Kemian 1. Under FP effect, activities of SPS and AI in sucrose regulation were decreased, while SuSy activity in sucrose degradation was increased. The changes in activities of SuSy and SPS in response to FP effect displayed different and large change ranges between the two cultivars. These results indicate that restrained cellulose synthesis and sucrose metabolism in distal FPs are mainly attributed to the changes in the activities of these enzymes. The difference in fiber quality, cellulose synthesis and sucrose metabolism in response to FPs in fiber cells for the two cotton cultivars was mainly determined by the activities of both SuSy and SPS.

“…During this process, SS is the key enzyme that regulates cellulose synthesis, affecting the cumulative rate and the amount of cellulose produced (Amor et al, 1995; Fujii et al, 2010). Wang et al (2009) thought that the SS activity contributes to the synthetic strength of cellulose in the fiber. We observed the reduced ability of colored cotton to transfer, utilize, and offload carbohydrates in all stages (Tables 3, 5, and 6).…”

Physiological Characteristics Associated with Fiber Development in Two Naturally Colored Cotton Cultivars

Core Ideas The dynamics of cellulose accumulation in colored cotton fiber increased in an S‐shaped curve, which was not asymmetric and could be simulated with Richards’ model (R2 > 0.999). Chlorophyll concentrations (estimated by SPAD values) for colored cotton were lower, compared to white cotton, and the degradation rate was relatively faster. This resulted in lower contents of soluble sugar in the boll shell and the subtending leaf. In the boll shell and the fiber, colored cotton had lower ATPase, sucrose invertase, and UDPG‐PPase activities. At 40 DPA, the SS activity for colored cotton was lower than for white cotton. Naturally colored cotton (Gossypium hirsutum L.) fibers are commercially valuable, but low fiber quality limits their use. This study investigates changes in enzymes’ activities and substance contents involved in carbohydrate synthesis to provide a theoretical basis for improving colored cotton fiber quality. Brown cotton Xiangcaimian 2, green cotton Wanmian 39, and white cotton Sumian 9 (control) were used. Fiber cellulose accumulation for Xiangcaimian 2 and Wanmian 39 were lower than the control. Cellulose content was simulated by Richards’ equation (R2 > 0.999) and follows an “S” pattern—initial slow accumulation 0–10 d post anthesis (DPA), then rapid 10–40 DPA, then slow 40–50 DPA. Maximum accumulation, the cumulative rate parameter, and maximum cumulative rate for cellulose of colored cotton were all lower for control. Further analysis showed SPAD chlorophyll meter readings, soluble sugar content, leaf sucrose invertase activity, adenosine triphosphatase, sucrose synthase, and uridine diphosphate glucose pyrophosphorylase (UDPG‐PPase) activities in colored fiber were lower than control. Results suggest insufficient nutrients for boll and fiber development, resulting in lower fiber quality and boll dry weight in colored cotton. Sucrose synthase and UDPG‐PPase activities in colored fiber were significantly correlated with fiber maturation (r = 0.884*, r = 0.914*) and fiber strength (r = 0.895*, r = 0.935*), indicating lower metabolite and enzyme activities in colored cotton reduced fiber quality. Therefore, it appears improving colored cotton fiber quality may require selection efforts to increase photosynthetic capacity in leaves and transportation capacity of carbohydrates in the boll to supply more nutrient during fiber development.

“…Zeolite loaded Ag + inorganic antimicrobial is the most deeply-researched and widely-used one by far, which is safe and highly efficient [1,2] . However, strong photosensitization of silver salts makes them discolor quite easily on light and long-term storage, and influences the colors of antimicrobial and its products, furthermore restricts the application of zeolite loaded Ag + inorganic antimicrobial seriously [3] .…”

Ag+-Zn2+-zeolite antimicrobial (AZZA) with high antibacterial efficiency and good color stability was prepared by ion-exchange method in water phase, followed by surface modification. Taking the modified AZZA as raw material, antibacterial polyethylene (PE) master batch was prepared and applied in PE plastic. In this paper, the technological parameters to prepare AZZA were optimized, and the effect of antimicrobial addition on the mechanical property and antibacterial property of PE plastic was studied as well. As shown in SEM analysis, AZZA particles were distributed homogeneously in PE plastic, and was compatible with the PE matrix well. The mechanical property of PE sample was not influenced notably when the adding amount of modified AZZA was less than 6%.
