Targeting of plasmodesmal proteins requires unconventional signals
The Plant Cell: In a NutshellGabriel Robles Luna, Jung-Youn Lee and colleagues discover that proteins carry targeting signals that send them to plasmodesmata, but these signals show no sequence conservation.

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…
SOS and SAS: The interaction of shade avoidance and salt tolerance responses
The Plant Cell: In a NutshellHan, Ma, et al. reveal the mechanistic connection between shade avoidance responses and salt-induced responses.
https://doi.org/10.1093/plcell/koad119
Background: Sun-loving plants compete with their neighbors for sunlight by initiating shade avoidance syndrome (SAS). Phytochromes are plant photoreceptors…
CYCLOIDEA-like genes control multiple floral traits
The Plant Cell: In a NutshellYang, Wang, Liu, et al. reveal that CYCLOIDEA-like genes control the genetic correlation of floral symmetry, floral orientation, and nectar guide patterns.
