Nearly 200 plant genomes have been sequenced over the last two years, and new functions of microRNAs (miRNAs) revealed. Therefore, timely update miRNA databases by incorporating miRNAs from newly species functional information is required to provide useful resources for advancing research. Here we report PmiREN2.0 (https://pmiren.com/) with an addition 19 363 entries 91 plants, doubling amount data in original version. Meanwhile, abundant regulatory centred on was added, including predicted...
Abstract The conserved microRNA (miRNA) miR408 enhances photosynthesis and compromises stress tolerance in multiple plants, but the cellular mechanism underlying its function remains largely unclear. Here, we show that Arabidopsis (Arabidopsis thaliana), transcript encoding blue copper protein PLANTACYANIN (PCY) is primary target for vegetative tissues. PCY preferentially expressed guard cells, associated with endomembrane surrounding individual chloroplasts. We found MIR408 promoter...
As a globally popular leafy vegetable and representative plant of the Asteraceae family, lettuce has great economic academic significance. In last decade, high-throughput sequencing, phenotyping, other multi-omics data in have accumulated on large scale, thus increasing demand for an integrative database. Here, we report establishment comprehensive database, LettuceGDB (https://www.lettucegdb.com/). omics hub, current includes two reference genomes with detailed annotations; re-sequencing...
MicroRNAs (miRNAs) are fast evolving endogenous small RNAs that regulate organism function and behavior in both animals plants. Although models for de novo miRNA biogenesis have been proposed, the genomic mechanisms driving swift diversification of repertoires plants remain elusive. Here, by comprehensively analyzing 21 phylogenetically representative plant species, ranging from green algae to angiosperms, we systematically identified events associated with 8,649 loci. We found 399 (4.6%),...
Abstract MicroRNAs (miRNAs) are rapidly evolving endogenous small RNAs programing organism function and behavior. Although models for miRNA origination have been proposed based on sporadic cases, the genomic mechanisms driving swift diversification of repertoires in plants remain elusive. Here, by comprehensively analyzing 20 phylogenetically representative plant species, we identified miniature inverted-repeat transposable elements (MITEs) as predominant sources de novo miRNAs angiosperms....
