Genomic regions associated with flag leaf and panicle architecture in rice (Oryza sativa L.).

Background: Flag leaf (FL) and panicle architecture (PA) are critical for increasing rice grain yield as well as production. A genome-wide association study (GWAS) can better understand the genetic pathways behind complex traits like FL and PA.

Results: In this study, 208 diverse rice germplasms were grown in the field at the Texas A&M AgriLife Research Center at Beaumont, TX, during 2022 and 2023 following Augmented Randomized Complete Block Design.

Reference-Guided De Novo Genome Assembly to Dissect a QTL Region for Submergence Tolerance Derived from Ciherang-Sub1.

Global climate change has increased the number of severe flooding events that affect agriculture, including rice production in the U.S. and internationally.
