(Submitter supplied) We show that trm5 plants have less m1G in tRNAs, a slower leaf initiation rate, delayed flowering, and reduced primary root length. Late flowering correlates with reduced transcription of floral activators CO, FT, SOC1 and AP1. We also show that TRM5 methylates tRNA position 37 of several nucleus-encoded tRNA species, trm5 plants have reduced m1G and TRM5 is localized to the nucleus. Our findings highlight the importance of the post-transcriptional tRNA modification m1G37 in plant growth and development.

(Submitter supplied) We characterized the biological and molecular functions of AtC3H17, a unique Arabidopsis gene encoding a non-tandem CCCH zinc finger protein, in plant development. To investigate the downstream regulatory mechanisms of AtC3H17, whole genome microarray expression profiling was carried out. The experiment was designed to identify differentially expressed genes between WT and AtC3H17-overexpressing transgenic plants (AtC3H17 OXs) grown for 14 days under SD growth conditions. more...

(Submitter supplied) The functions of miRNAs and their target mRNAs in Arabidopsis development have been widely documented, however, roles of stress responsive miRNAs and their targets are not as well understood. Using small RNA deep sequencing and ATH1 microarrays to profile mRNAs, we identified IAR3 (IAA-Ala Resistant 3) as a novel target of miR167a.

(Submitter supplied) N6-methyladenosine (m6A) is the most abundant internal modification in the messenger RNA (mRNA) of all higher eukaryotes. This modification has been shown to be reversible in mammals; it is installed by a methyltransferase heterodimer complex of METTL3 and METTL14 bound with WTAP, and reversed by iron(II)- and α-ketoglutarate-dependent demethylases FTO and ALKBH5. This modification exhibits significant functional roles in various biological processes. more...
