Interdisciplinary Team Addresses Cotton Leafroll Dwarf Virus in Alabama

Abstract

A multi-state and interdisciplinary team was formed to address the Extension and research needs of CLRDV, an emerging cotton disease with high potential impact for U.S. cotton production. In 2017, CLRDV was identified in AL and Auburn University immediately formed an interdisciplinary working group composed of plant breeders, plant pathologists, entomologists, and agronomists. Since then, scientists from ten other states have joined the CLRDV group. Thus, allowing research to be coordinated efficiently and best deploy limited resources to attend the stakeholder’s needs. The CLRDV group produces and shares new and relevant information with the scientific community and cotton producers alike.

A newly isolated cotton-infecting Polerovirus with cryptic pathogenicity encodes a weak suppressor of RNA silencing

“…major pests affecting the yield (Ziegler-Graff, 2020; Tarazi and Vaslin, 2022). Cotton leafroll dwarf virus (CLRDV) is the second most damaging virus to commercial cotton worldwide, reported in all cotton-growing continents (Distefano et al, 2010;Agrofoglio et al, 2019;Conner et al, 2021). CLRDV is a member of the genus Polerovirus (family Solemoviridae) and the causal agent for the cotton blue disease (Parkash et al, 2021;Sõmera et al, 2021).…”
