Summary: Light quality, specifically red and blue lights, have different effects on the biosynthesis and accumulation of anthocyanins in plants. Various genes related to pathways such as circadian rhythm and anthocyanin biosynthesis are differentially expressed under different light conditions. Red light induces the up-regulation of genes related to proanthocyanidin biosynthesis more significantly compared to blue light, leading to lower accumulation of anthocyanins under red light.

Summary: In this study, three carbon-chain extension genes associated with fatty acid synthesis in upland cotton were cloned and characterized. These genes play important roles in oil accumulation in cotton seeds and fiber elongation. The expression patterns of these genes varied during different stages of seed development, and their overexpression resulted in increased oil content.

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.

Summary: The diameter of cotton fiber is set early by cell-specific processes involving the regulation of microtubules, impacting traits like length, strength, and diameter. Microtubule antagonists can affect fiber morphology, with variations seen between different fiber types. The study demonstrates cell-specific mechanisms in regulating fiber expansion near the apex, with microtubules playing a role in this process.

Summary: Research on the effects of mutations in the secondary wall CesA gene AtcesA7 on the null mutant showed a gradient of rescue effects by different variants, suggesting a specific cellulose content threshold for certain developmental processes. Tissue-specific analysis using vibrational sum frequency generation microscopy revealed subtle differences between genotypes that correlated with the extent of rescue of collapsing xylem phenotype.

Summary: Postharvest fungal pathogen Botrytis cinerea actively induces ripening in tomato fruit to facilitate infection, depending on the presence of two fungal polygalacturonases. It accelerates external coloration, ethylene production, and softening in unripe fruit while upregulating host genes involved in ripening processes. Glycomic analysis also showed similar changes in cell wall polysaccharides between infected unripe fruit and ripe healthy fruit. The failure to accelerate ripening severely inhibits fungal survival on unripe fruit.

Summary: Upon wetting, chia nutlets produce a gel-like capsule of mucilage, which is a significant part of their dietary fibre content. The composition and structure of chia nutlet mucilage are complex and contain several types of polymers. The fermentation of chia nutlet mucilage is poor, with only oligosaccharides being fermentable substrates. Grinding chia nutlets improves the fermentation and bioaccessibility of key nutrients, including dietary fibre.

Summary: The annual temperate grass Brachypodium distachyon is used as a model system for monocot biomass crops and lignocellulosic recalcitrance study. Its cell walls differ from dicot plants and closely resemble those of other grasses. Antibodies against glycan epitopes were used to investigate glycan distribution in Brachypodium's root and leaf tissues. The differences in epitope presence between tissues and cell types provide insights into monocot biomass.
