	1	Arab/c/opste N^(6)-methyladenosine reader CPSF30-L recognizes FUE signals to control polyadenylation site choice in liquid-like nuclear bodies显示文摘The biological functions of the epitranscriptomic modification N^(6)-methyladenosine(m^(6)A)in plants are not fully understood.CPSF30-L is a predominant isoform of the polyadenylation factor CPSF30 and consists of CPSF30-S and an m^(6)A-binding YTH domain.Little is known about the biological roles of CPSF30-L and the molecular mechanism underlying its m^(6)A-binding function in alternative polyadenylation.Here,we charac-terized CPSF30-L as an Arabidopsis m^(6)A reader whose m^(6)A-binding function is required for the floral tran-sition and abscisic acid(ABA)response.We found that the m^(6)A-binding activity of CPSF30-L enhances the formation of liquid-like nuclear bodies,where CPSF30-L mainly recognizes m*A-modified far-upstream elements to control polyadenylation site choice.Deficiency of CPSF30-L lengthens the 3'untranslated region of three phenotypes-related transcripts,thereby accelerating their mRNA degradation and leading to late flowering and ABA hypersensitivity.Collectively,this study uncovers a new molecular mechanism for m^(6)A-driven phase separation and polyadenylation in plants.
