Summary: This study proposes a framework for modeling the spectral response of cotton plants under fall armyworm attacks using machine learning algorithms. Through organizing spectral wavelengths, the Random Forest algorithm was found to be the most suitable model. The best spectral regions range from 650 to 1350 nm and 1570 to 1640 nm.

Summary: The study found that the three partiti-like viruses were harmful to the new host, causing increased mortality. The viruses did not affect host fecundity or susceptibility to other pathogens. Transcriptome analysis indicated that the viruses could impact host gene-expression profiles.

Summary: This research found that applying insecticides 48 hours after pollination is the optimal time for controlling corn earworm and fall armyworm. Emamectin benzoate and chlorantraniliprole showed good efficacy in controlling the larvae of these pests. Chlorantraniliprole and spinetoram should be sprayed when infestations of larvae in earlier instars are observed, while emamectin benzoate should be applied to larvae in later instars.

Summary: Novel structural variations were identified in cotton chloroplast tRNAs, and gene loss events were more prominent than duplications in chloroplast tRNAs. Analysis of 27 Gossypium species' chloroplast tRNAs revealed new tRNA structural variations in cotton plants.

Summary: Nitrogen plays a crucial role in cotton growth and yield. This study found that moderate to high levels of nitrogen improved the growth, photosynthesis, and yield of CCRI-69 cotton. These levels also increased the enzymatic activities involved in carbon and nitrogen metabolism in the subtending leaves. There was a strong correlation between the nitrogen concentration in subtending leaves and various physiological parameters and yield. These findings highlight the importance of nitrogen concentration in subtending leaves for improving cotton yield and could be used in breeding nitrogen-efficient cotton genotypes.

Summary: Cotton is an important cash crop worldwide, and distinctness determination is challenging in cotton testing. This study characterized 1,242 cotton varieties using 42 SSR markers and found a mean genetic similarity of 46.7% and 58.5% for conventional and hybrid varieties, respectively. A GAIA distance was formulated for cotton varieties for the first time, and a scheme of selecting similar varieties using genetic and phenotypic distances was suggested. This approach can reduce the number of similar varieties required for testing.

Summary: The reaction parameters of K in-situ catalytic pyrolysis of cotton stalks at 600 degrees C were examined using the horizontal fixed bed pyrolysis method. The influence of K on the pyrolysis conversion mechanism of cotton stalks was investigated through various analyses. The addition of K2CO3 accelerated the breakdown of oxygen-containing rings, promoted the conversion of furan structure, and prevented the transformation of furan into long-chain alkanes.

Summary: This study investigated the degradation of cotton and wood celluloses treated with hydrogen chloride in different media for different durations. The use of alcohols increased the cellulosic sugar content in the hydrolysate compared to water, but resulted in lower cellulose recovery rates. The crystallinity indices of celluloses changed slightly after degradation, and the weight-average degree of polymerization plateaued after a certain treatment time.

Summary: This study evaluated the effect of cryogrinding, a relatively new, cost-effective, and sustainable mechanical treatment method, on the physicochemical properties of different types of cellulose fibers. The results showed that cryogrinding can improve the properties of cellulose, particularly by reducing its degree of polymerization, indicating the potential of this technique in cellulose processing.

Summary: The study identified a novel stem pigment gland-forming gene, GoSPGF, responsible for glandless trait on the stem in cotton. Loss of GoSPGF significantly affects gossypol biosynthesis and alters the expression of related genes. This discovery provides insights into the regulation of glandular structure differentiation and formation in cotton, with potential implications for other plants with special gland structures.

Summary: China has achieved significant achievements in cotton production since the founding of the People's Republic of China in 1949. It has maintained its position as the world's largest cotton producer for 33 years, with average annual increases of 3.5% and 3.9% in unit yield and total output, respectively. Cotton production has played a crucial role in the development of the national economy and improvement of living standards. Despite a reduction in cotton planting area, the continuous increase in unit yield has resulted in relatively stable total output. China's dominant position in global cotton production is attributed to the progress and development of cotton cultivation technology.
