The aflatoxins content of 140 cotton seed samples were determined using high-performance liquid chromatography. Samples were obtained from wholesalers in Iran between May 2010 and June 2011. Aflatoxin B₁ gave the highest incidence of contamination and was found in 129 of the 139 samples. The highest concentration of aflatoxin was 14.4 ng g⁻¹. Thirteen cotton seed samples (9.35%) were above one of the regulatory limits of the European Union (5 ng g⁻¹), but no sample was above the highest EU limit and the safety limit recommended by the FDA (20 ng g⁻¹) and regulatory limits of Iran (50 ng g⁻¹) for total aflatoxin.

This study presents a sustainable and low-cost approach to biodiesel production using non-edible cottonseed oil and a novel nickel-doped chicken eggshell-derived catalyst. The catalyst was synthesized via nickel impregnation followed by calcination at 900 °C to facilitate the decomposition of CaCO₃ into catalytically active CaO and promote nickel oxide formation for enhanced surface reactivity. Process optimization using Response Surface Methodology (RSM) resulted in a maximum fatty acid methyl ester (FAME) yield of 98.

Transposable elements (TEs) serve as important drivers mediating polyploidization events and phenotypic diversification in plant genomes. However, the dynamic changes in various TE subclasses post-polyploidization and their mechanisms of influencing phenotypic variation require further investigation. The allopolyploid species, originating from two diploid progenitors, provide an ideal model for studying TE dynamics following polyploidization.

Cottonseeds, rich in high-quality protein and fatty acids, represent a vital plant-derived feedstuff and edible oil resource. To systematically investigate genetic variation patterns in nutritional quality and screen superior germplasm, this study analyzed 26 nutritional quality traits and 8 fiber traits across 259 upland cotton ( L.) accessions using multivariate statistical approaches.

Background: L. is one of the main economic crops worldwide, and increasing the size/weight of its seeds is a potential strategy to improve its seed-related yield. AINTEGUMENTA (ANT) is an organogenesis transcription factor mediating cell proliferation and expansion in , but little is known about its candidate function in upland cotton seed.

The B3-domain transcription factor ABI3 (ABSCISIC ACID INSENSITIVE 3) is a critical regulator of seed maturation, stress adaptation, and hormonal signaling in plants. However, its evolutionary dynamics and functional roles in cotton ( spp.) remain poorly characterized.
