Gene Details:
- Gene ID: TRIAE_CS42_4DS_TGACv1_361189_AA1163110
- Gene Symbol: Ms2
- Gene Name: male-sterile
- Genome: Chinese_Spring1.0
- Species: Triticum aestivum
Functional Descriptions:
- The male-sterile Ms2 mutant has been known for 40 years and has become extremely important in the commercial production of wheat.
- Ms2 mutant plants produce abnormal anthers with no pollen. The male sterility phenotype is conferred by a single dominant gene Ms2, which was found to be located on the short arm of chromosome 4D by cytogenetic analysis7.
- Use of the Ms2 mutant thus obviated the need for the labour-intensive emasculation step in the production of hybrid wheat seed and, more importantly, accelerated the recurrent selection process in wheat.
- This TRIM element is responsible for the anther-specific Ms2 activation that confers male sterility.
- TRIM-induced expression of the intact Ms2 reveals a potential mechanism of gene activation in plants.
- Fertility recovery of wheat male sterility controlled by Ms2 using CRISPR/Cas9.
