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: By integrating a large number of samples and time points, this study reveals the genetic basis of fiber quality differences between Gossypium hirsutum and Gossypium barbadense. Key genes involved in fiber development were identified, providing a theoretical basis for breeding high-quality cotton and gene function analysis.

Summary: Cotton breeding programs need to select for tolerance to high temperature extremes to prevent environment-induced yield loss. Methods that combine chlorophyll fluorescence induction measurements with temperature response experiments can be used to identify genotypic variation in photosynthetic thermotolerance. Cotton genotypes differ significantly in photosynthetic thermotolerance, and different photosynthetic processes have varying sensitivities to high temperature, with intersystem electron transport being the most heat sensitive.

Summary: Transgenic insect-resistant cotton has a dominant position in cotton cultivation in Pakistan, accounting for over 90% of the cotton fields. A two-year field study found that transgenic cotton did not affect the yield of winter crops (wheat, Egyptian clover, and canola) and the overall productivity of the cropping system.

Summary: Enhancing pollinator communities and the services they provide within agricultural landscapes is a global priority. Despite the advantages of floral strips or hedgerows as part of pollinator habitat enhancement efforts, opportunity costs incurred by removing land from agricultural production can outweigh the benefits of enhanced pollination to remaining crops. Conservation tillage is a practice that has the potential to improve habitat while maintaining agricultural productivity.

Summary: This study assessed the dispersal pattern of boll weevil in cotton fields during dry and wet seasons. The results showed that adult weevils and infested reproductive structures exhibited an aggregated distribution in both seasons. Infestations started at field borders and monitoring should focus on total infested reproductive structures.

Summary: The study identified that ghr-miR397 and GhLAC4 play important roles in lignin biosynthesis and defense-induced lignin biosynthesis. Knockdown of ghr-miR397 increased lignin accumulation and enhanced plant resistance, while knockdown of GhLAC4 and overexpression of ghr-miR397 reduced lignin content and made plants more susceptible to fungal infection. Additionally, lignin was found to protect plant cell walls from degradation by cellulase or fungal secretions.
