MTA | mRNA adenosine methylase | Arabidopsis (Arabidopsis thaliana) | form m6A methylation complex | nucleus | • mta, mtb, fip37 and vir are embryo-lethal • mature mta, mtb, fip37 and vir plants show alerted vascular development, gravitropic response, roots growth and flowering timing • mta mutants are characterized by small, bushy rosettes and alerted flower and trichome architecture • hakai-1 and hakai-2 mutants resembled wild type plants [23,24,25,26,27], |
