GhMAC3e is involved in plant growth and defense response to Verticillium dahliae.

GhMAC3e expression was induced by various stresses and hormones. GhMAC3e may regulate plant growth by influencing auxin distribution, and play important roles in Verticillium wilt resistance via mediating SA signaling. The MOS4-Associated Complex (MAC) is a highly conserved protein complex involved in pre-mRNA splicing and spliceosome assembly, which plays a vital role in plant immunity.

Combining QTL-seq and linkage mapping to fine map a candidate gene in qCTS6 for cold tolerance at the seedling stage in rice.

Background: Cold stress caused by low temperatures is an important factor restricting rice production. Identification of cold-tolerance genes that can stably express in cold environments is crucial for molecular rice breeding.

Results: In this study, we employed high-throughput quantitative trait locus sequencing (QTL-seq) analyses in a 460-individual F mapping population to identify major QTL genomic regions governing cold tolerance at the seedling stage in rice.
