Taxon: rice ✕

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Title

Identification and Gene Cloning of a Brittle Culm Mutant (bc22) in Rice

Xiying Cao; Tao Zhou; Yue Sun; et al. Agriculture 2024. doi:10.3390/agriculture14020235

Other claims from this paper (10)

Observation bc22 culms were more fragile and mechanically weaker than LR005.
Observation bc22 had shorter plants and panicles and smaller grains.
Observation bc22 lacked glume hairs.
Observation bc22 culm hemicellulose content increased significantly.
Observation bc22 culm lignin content was reduced.
Observation A single recessive gene governed the brittle culm trait.
Observation LOC_Os02g25230 was identified as the bc22 candidate gene.
Mechanism Complementation confirmed that the proline to leucine substitution in LOC_Os02g25230 caused the bc22 phenotype.
Observation BC22 expression was higher in culms, leaves and spikelets than roots.
Mechanism BC22 may influence culm brittleness through cell wall biosynthesis.
