Euglena gracilis is a eukaryotic single-celled and photosynthetic organism grouped under the kingdom Protista. This phytoflagellate can accumulate the carbon photoassimilate as a linear β-1,3-glucan chain called paramylon. This storage polysaccharid

CURLY LEAF (CLF) encodes the methyl-transferase sub-unit of the PolycombRepressor Complex 2 (PRC2), which regulates the expression of target genesthrough H3K27 tri-methylation. We isolated a new CLF mutant allele (clf-78)using a genetic screening des

Roots are the anchorage organs of plants, responsible for water and nutrient uptake, exhibiting high plasticity. Root architecture is driven by the interactions of biomolecules, including transcription factors and hormones that are crucial players re

HASTY, the plant ortholog of human exportin 5, was proposed to export miRNAs from the nucleus to the cytoplasm, whereas this has long been disputed. This study shows that HASTY, rather than acting as a miRNA cargo protein, promotes miRNA biogenesis b

The shift of dark-grown seedlings into light causes enormous transcriptome changes followed by a dramatic developmental transition. Here, we show that miRNA biogenesis also undergoes regulatory changes during de-etiolation. Etiolated seedlings mainta
