CHM — Brassica juncea

Summary

BJUA07G07060S (CHM, BjCHM) encodes a protein with domains characteristic of DNA mismatch repair, including a P-loop NTPase and mispair-binding activity, and is annotated for ATP-dependent DNA damage sensor activity and double-stranded DNA binding. In Indian mustard (Brassica juncea) on chromosome A07, this gene is associated with mitochondrial DNA recombination and metabolism, homologous chromosome segregation, chiasma assembly, meiotic recombination, anther development, and response to heat. It localizes to the mitochondrion, plastid, thylakoid membrane, nucleus, and MSH2/MSH6 complex. The gene is associated with cytoplasmic male sterility, leaf variegation, plastid genome stability, stress tolerance (including heat, cold, salt, and abiotic stress), flowering time, stomatal density, shoot branching, and growth rate. Related genes in other species are linked to mitochondrial genome stability, DNA repair, and phenotypic plasticity.
