Gene construction kit crack2/2/2023 ![]() ![]() These genes were co-localized to the major QTL region. Both genes encode proteins involved in calcium binding, ion transport, and Ca 2+ signal transduction, which are important for regulating plant development and adaptations to the environment. We subsequently identified two candidate genes, RsANNAT and RsCDPK. The QTL ‘ RCr1’ was responsible for 4.47–18.11% of variance in the root cracking phenotype. ![]() Ten QTLs were distributed in six linkage groups, among these QTLs, ‘ RCr1’ in LG1 was detected over 3 consecutive years and was considered to be a major QTL for root cracking. In this study, quantitative trait loci (QTLs) putatively associated with radish root cracking were mapped. The genetic and physiological mechanisms underlying this root cracking disorder have not been characterized. Root cracking is a severe physiological disorder that significantly decreases the yield and commercial value of radish. A major QTL conferring tolerance to radish ( Raphanus sativus) root cracking was mapped for the first time and two calcium regulatory genes were identified that positively associated with the cracking phenomenon. ![]()
