From: Genome-wide response to selection and genetic basis of cold tolerance in rice (Oryza sativaL.)
Putative genetic networks underlying rice seedling cold tolerance (CT) detected in 30 cold-tolerant introgression lines (ILs) from four BC 2 populations. (A) Genetic network consisting of five functional genetic units (FGUs) and their graphic genotypes in six cold-tolerant ILs from the C418/Zihui100 population. (B) Genetic network consisting of six FGUs and their graphic genotypes in six cold-tolerant ILs from the C418/Bg300 population. (C) Genetic network comprising 15 FGUs detected in 13 cold-tolerant ILs from the C418/Cisanggarung population. (D) Genetic network consisting of three FGUs and their graphic genotypes in five cold-tolerant ILs from the C418/Manawthukha population. In graphical genotypes of each network, unfilled and fully colored cells represent the recipient homozygote and donor functional genotypes (donor homozygote plus the heterozygote), respectively. Numbers in cells of graphic genotypes are the number of loci included in the FGU (1 represents a single locus, while ≥ 2 represents an association group, AG). Here, an AG represents a group of unlinked but perfectly associated loci as shown in Table 3.
