TranscriptomicsOsJMJ703, a Histone H3K4 Demethylase, Controls Transposon Activity in Rice
Retrotransposons are classified into long terminal repeat (LTR) or non-LTR retrotransoposons, and both types can mobilize in a “copy and paste” manner. Rice genome contains >40% of repetitive sequences or transposable elements (TEs) that scattered throughout the genome. TE activities are tightly reg...

TranscriptomicsIntegrative genome-wide analysis reveals HLP1, a novel RNA-binding protein? regulates plant flowering by targeted alternative polyadenylation
Alternative polyadenylation (APA) is a widespread mechanism for gene regulation and has been implicated in flowering, but the molecular basis governing the choice of a specific poly(A) site during the vegetative-to-reproductive growth transition remains unclear. Here we characterize HLP1, an hnRNP A...

TranscriptomicsControl of agricultural traits by hc-siRNA associated MITEs in rice
Transposable elements (TEs) and repetitive sequences comprise over 40% of rice genome. Different TEs are tightly regulated by distinct epigenetic mechanisms. For example, the activities of LTR retrotransposon Tos17 and non-LTR retrotransposon LINE element Karma are uniquely regulated by histone H3K9...

TranscriptomicsNOT2 proteins promote Pol II-dependent transcription and interact with multiple miRNA biogenesis factors in Arabidopsis
MicroRNAs (miRNAs) play key regulatory roles in numerous developmental and physiological processes in animals and plants. The elaborate mechanism of miRNA biogenesis involves transcription and multiple processing steps. Here, we report the identification of a pair of evolutionarily conserved NOT2_3_...

TranscriptomicsDifferential gene expression in ref6-1
We demonstrate that REF6/JMJ12 (RELATIVE OF EARLY FLOWERING 6/Jumonji domain-containing protein 12) is an H3K27me3 and H3K27me2 demethylase. Plants overexpressing REF6/JMJ12 resemble mutants defective in H3K27me3-mediated gene silencing. Genetic interaction tests indicate that REF6/JMJ12 acts downst...

GenomicsGenome-wide comparison of H3K27me3 difference between ref6-1 and wild type Col
We demonstrate that REF6/JMJ12 (RELATIVE OF EARLY FLOWERING 6/Jumonji domain-containing protein 12) could demethylate H3K27me3. Loss of REF6/JMJ12 leads to ectopic and increased H3K27me3 of a large spectrum of genes involved in development and responses to stimuli. Examination of differences in H3K2...

TranscriptomicsRNase ZS1-mediated UbL40 mRNA decay controls thermo-sensitive genic male sterility in rice.
Male sterility is an important trait in hybrid crop breeding. Thermo-sensitive genic male sterility (TGMS) lines, which are male-sterile at restrictive (high) temperatures but convert to male-fertile at permissive (low) temperatures, have been widely utilized in two-line hybrid rice breeding3. Howev...

TranscriptomicsRoles of RDR701 and DCLs in Rice PhasiRNA biogenesis
In this study, we analyzed function of the rice RDR701 and various DCLs proteins in small RNA processing. small RNA deep sequencing analyses revealed that RDR701 and OsDCL4 is involved in tasiRNAs and 21- and 24-nt phasiRNAs biogenesis. Further analyses indicate RDR701 coupling with OsDCL4 and OsDCL...

TranscriptomicsProtein arginine methyltransferase AtPRMT5 is involved in pre-mRNA splicing in Arabidopsis thaliana
In this study, we analyzed the Arabidopsis homologue of PRMT5, AtPRMT5M-bM-^@M-^Ys function in RNA processing. RNA-seq analyses revealed that AtPRMT5 is involved in a subset of pre-mRNA splicing. Several RNA processing factors involved in regulating flowering time were validated that the correspondi...
