Microtubules Dynamics Regulates Mesocotyl Elongation in Rice

Abstract:

Mesocotyl elongation in rice is essential for seedling emergence. Our previous screening identified weedy rice accessions (Oryza sativa f. spontanea L.) (WR04-6) with unusual long mesocotyl. In this study, using rice cultivar Akihikari (Oryza sativa, subspecies japonica) as control, we observed that weedy rice accessions display more extensive microtubules (MTs) depolymerization in the early stage of mesocotyl elongation. At the end of mesocotyl elongation, the predominant MTs in weedy rice are transversely oriented, while, Akihikari has oblique MTs arrays.
