Screening of historical and current Upland and Pima cotton germplasm for resistance to Rhizoctonia solani

open access: yesBMC Research Notes
Objective The fungus Rhizoctonia solani is an important seedling pathogen to many plant hosts including cotton (Gossypium). For multiple annual crops there have been relatively few screenings of germplasm conducted to identify potential sources of ...

SBP‐Box Transcription Factor JcSPL9 Regulates Both Seed Yield and Oil Content in the Biofuel Plant Jatropha curcas

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Jatropha curcas is a promising feedstock for biodiesel and bio‐jet fuels production; however, its seed yield is constrained by limited inflorescences. SPL9 is a member of the SBP‐box gene family that promotes the juvenile‐to‐adult phase transition.

Abundant Small Genetic Alterations after Upland Cotton Domestication

open access: yesBioMed Research International, 2018
Domestication has long been recognized as the most direct and effective way to intentionally influence morphological and physiological phenotypes in plants and animals. Consequently, understanding how small genetic alterations contribute to domestication is of considerable importance.

A Natural LTR Retrotransposon Insertion in the Promoter of GhNAC140‐Dt Boosts Cotton Lint Yield

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Transposable elements (TEs) are fundamental drivers of crop evolution and domestication. Whereas the underlying mechanisms of TE‐mediated gene activation remain poorly understood. Lint percentage is an important yield component in cotton. Here, we report a retrotransposon insertion in the promoter of GhNAC140‐Dt, a secondary wall NAC encoding ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

International genetic, cytogenetic and germplasm resources for cotton genomics and genetic improvement [PDF]

open access: yes, 2008
A general understanding of the nature, uses and need of cotton germplasm collections is important to maintaining support for them and their utilization. Such support is vital to addressing the future challenges and needs of cotton, which will be many and

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

open access: yesJournal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.
