Nascent pri-miRNAs and HYL1 act as a scaffold to recruit transcriptional regulators to miRNA loci
The Plant Cell: In a NutshellPark et al. reveal how a microprocessor component and a histone deacetylase act in microRNA biogenesis under stress.
Background: MicroRNAs (miRNAs) are small noncoding RNAs with a length of 21–24 nucleotides that play critical roles in mRNA silencing and translational suppression. In plants, miRNAs…
Sending out an SOS: Interplay between salt stress and light signaling
The Plant Cell: In a NutshellMa, Han, et al. explore the molecular mechanism underlying the interplay between light and salt stress pathways.
Background: The Salt Overly Sensitive (SOS) pathway is evolutionarily conserved and essential for plant adaptation to salt stress. The protein kinase SOS2 functions as a network hub in…
