Abstract
A mutation site of an ideal brittle culm mutant ibc in rice, a controlling gene IBC, and use thereof are provided. The controlling gene IBC has: (1) a nucleotide sequence shown in SEQ ID NO: 1 or SEQ ID NO: 2; or (2) a nucleotide sequence of a mutant, an allele, or a derivative generated by adding, substituting, inserting or deleting one or more nucleotides. The present disclosure further provides an encoded protein of the controlling gene IBC, a recombinant construct, a recombinant host cell, a method for embrittling culms in a rice ripening stage by using the controlling gene IBC, and use thereof. In a mutant with allelic variation in the gene IBC and loss of gene editing function, culms exhibit a brittle culm phenotype at the late ripening stage, leaves are not brittle, yield traits are excellent, and other agronomic traits are not obviously changed.
