[Methods] The karst core regions of southwest China, specifically Guizhou, Guangxi, and Yunnan, were investigated for the first time to analyze the species diversity characteristics of wood-decaying fungi in this area. This analysis was conducted through a comprehensive 5-year field investigation and systematic identification process. [Results] The wood-decaying fungi exhibited a distinctive species composition and distribution pattern within karst habitats, encompassing significant groups such as Polyporaceae and Hymenochaetaceae. Furthermore, these fungi demonstrated varying functional characteristics across the two ecological types of standing tree decay and wood decay. It was observed that wood-decaying fungi had a significant impact on the material cycle within karst ecosystems by degrading lignin and cellulose. Furthermore, the distribution of species diversity was closely associated with the characteristics of karst geomorphology and the types of vegetation. [Conclusions] This study not only addresses the lack of background data regarding wood-decaying fungi resources in karst regions, but also elucidates the maintenance mechanisms of fragile ecosystems from the perspective of decomposers. It provides a scientific foundation for biodiversity conservation, the prevention and control of forest diseases, and sustainable ecological management in karst regions.展开更多

文摘Antimony(Sb)contamination in paddy fields can lead to its accumulation in rice grains,posing a threat to food safety.To address this issue,the combined use of zero-valent iron(ZVI)and biochar(BC)were applied to decrease the uptake of Sb in Sb-polluted soils,and their effects on Sb uptake from soil to rice grains were investigated.Our results showed that the combination treatment of 0.05%ZVI and 0.095%BC resulted in a significant decrease(42.8%)in Sb accumulation in rice grains that was comparably more efficient than that by 0.05%ZVI(decrease of 15.8%Sb accumulation)or 0.095%BC(decrease of 12.7%Sb accumulation)alone,demonstrating the synergistic effect of ZVI and BC on mitigating Sb uptake by rice plants.ZVI presence resulted in the formation of iron oxides in the soil and on root surfaces,and the S^(2-)/S_(2)^(2-)ascent also increased by 58.7%on day 75 compared with that of the control,facilitating the reduction of Sb(Ⅴ)to less mobile Sb(Ⅲ),thereby decreasing Sb accumulation in rice plants.BC initially increased themobility of Sb owing to its alkaline nature,whereas the electron shuttle properties of BC contributed to a decrease in Sbmobility.The abundance of the arsenite-reducing gene arrA ultimately increased by 203.2% on day 120 compared with the initial phase on day 5,and BC caused a remarkable increase in arrA gene abundance.This study revealed the synergistic mechanisms by combining ZVI and BC to mitigate Sb uptake by rice,which may be useful for the sustainable remediation of contaminated rice paddies.

文摘[Objectives] To investigate the species diversity of wood-decaying fungi in karst regions of southwest China. [Methods] The karst core regions of southwest China, specifically Guizhou, Guangxi, and Yunnan, were investigated for the first time to analyze the species diversity characteristics of wood-decaying fungi in this area. This analysis was conducted through a comprehensive 5-year field investigation and systematic identification process. [Results] The wood-decaying fungi exhibited a distinctive species composition and distribution pattern within karst habitats, encompassing significant groups such as Polyporaceae and Hymenochaetaceae. Furthermore, these fungi demonstrated varying functional characteristics across the two ecological types of standing tree decay and wood decay. It was observed that wood-decaying fungi had a significant impact on the material cycle within karst ecosystems by degrading lignin and cellulose. Furthermore, the distribution of species diversity was closely associated with the characteristics of karst geomorphology and the types of vegetation. [Conclusions] This study not only addresses the lack of background data regarding wood-decaying fungi resources in karst regions, but also elucidates the maintenance mechanisms of fragile ecosystems from the perspective of decomposers. It provides a scientific foundation for biodiversity conservation, the prevention and control of forest diseases, and sustainable ecological management in karst regions.
文摘This study compared the control effect of 110 g/L etoxazole SC,15%abamectin·etoxazole SC,30%cyetpyrafen SC,43%bifenazate SC and 1.8%abamectin EC five acaricides sprayed by unmanned aerial vehicle(UAV)on Panonychus citri,aiming to screen out the appropriate acaricide for the control of this pest by UAV spraying.The results showed that 15%abamectin·etoxazole SC and 30%cyetpyrafen SC had the highest control efficacy,which remained above 90%14 d after application.Secondary performance was observed in 43%bifenazate SC and 110 g/L etoxazole SC,which demonstrated enhancing control effect.However,1.8%abamectin EC showed slower effect.Considering the control effect and population reduction rate of P.citri,15%abamectin·etoxazole SC and 30%cyetpyrafen SC were suggested as the effective acaricides for the control of this pest.

文摘Fruit cracking is a persistent challenge for table grape growing.To investigate the mechanism of this disorder,a comprehensive two-year investigation was conducted to assess the fruit cracking percentage of 15 table grape(Vitis vinifera L.)varieties.Based on the findings,the cracking-susceptible variety‘Xiangfei'and the cracking-resistant variety‘Zuijinxiang'were selected for further study.Fruit growth curves for‘Zuijinxiang'and‘Xiangfei'were plotted based on fruit diameter and total soluble solids content,revealing that both varieties exhibited typical double-sigmoidal patterns that were highly similar.The period between 48 and 53 days after full bloom(DAFB)was identified as the critical phase for fruit cracking incidence.Furthermore,during the fruit cracking period,‘Xiangfei'fruit exhibited significantly higher water content and mesocarp cell area compared with those of‘Zuijinxiang'.Applying aquaporin inhibitors(nano-silver)to‘Xiangfei'berries reduced fruit water uptake and cracking percentage,whereas applying aquaporin activators(forskolin)to‘Zuijinxiang'berries increased fruit water uptake and cracking percentage.Additionally,expression analysis of six genes associated with plasma membrane intrinsic proteins(PIPs)synthesis(VvPIP1;1,VvPIP1;2,VvPIP1;3,VvPIP2;1,VvPIP2;2,and VvPIP2;3)revealed that only the expression level of VvPIP1;1 was higher in‘Zuijinxiang'than in‘Xiangfei'during the fruit cracking period,whereas the expression levels of the other genes exhibited no significant difference between the two varieties.Transgenic overexpression of VvPIP1;1 in tomato resulted in increased fruit water content,enlarged mesocarp cell size,and enhanced fruit cracking percentage.These findings indicate that VvPIP1;1 plays a pivotal role in controlling grape berry cracking.
