  2. Genetic network regulating variation in vegetative phase change in maize

    Zhang, WeiUniversity of Illinois at Urbana-Champaign2011

    … Also, continuous variation of leaf identity traits in diverse genetic mapping populations indicates the feasibility to use quantitative trait locus (QTL) analyses to find underlying genes. I demonstrate here that Glossy15 (Gl15) is the most important gene controlling leaf identity traits in …
