Silencing of <i>GhSHP1</i> hindered flowering and boll cracking in upland cotton.

ABSTRACT: The opening of cotton bolls is an important characteristic that influences the precocity of cotton. In the field, farmers often use chemical defoliants to induce cotton leaves to fall off earlier, thus accelerating the cracking of cotton bolls. However, the molecular mechanism of cotton boll cracking remains unclear. We identified ten AGAMOUS subfamily genes in upland cotton. Three pairs of Gossypium hirsutum AG subfamily genes (GhAGs) were amplified via tandem duplication. The promoters of the GhAGs contained a diverse array of cis-acting regulatory elements related to light responses, abiotic stress, phytohormones and plant growth and development. Transcriptomic analyses revealed that the expression levels of GhAG subfamily genes were lower in ve
