Gene expression analysis during the fruit development in dehiscent and indehiscent Bixa orellana L. accessions.

ABSTRACT: Fruit morphology and dehiscence-related genes were analyzed in dehiscent N4P and dehiscent P12 Bixa orellana accessions. Fruit architecture (exocarp and pericarp cells, trichomes, vascular bundles, vesicles, and bixin cells) documented by Scanning electron microscopy (SEM) morphology, blue toluidine stain, and phloroglucinol and hydrochloric acid (PHCL) stain was similar in both accessions. Although, the dehiscent zone (DZ) was higher in the indehiscent P12 B. orellana accession, lignification values, obtained by phloroglucinol and hydrochloric acid stain, within the DZ remain was similar in both variants being lower at 34 days after floral anthesis in the dehiscent N4P B. orellana accession. Dehiscence-related genes APETALA (AP2), SHATTERPROOF (
