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…
Review: Rapid auxin signaling: Unknowns old and new
Plant Science Research WeeklyYou might think you’ve read enough about auxin, but I recommend you take this opportunity to read one more article, this very interesting and enjoyable review by Fielder and Friml. Auxin has figured prominently in both the classical and molecular eras of plant biology. However, the exciting findings…
Review: Genome evolution in plants and the origins of innovation
Plant Science Research WeeklyLand plants have enormous diversity; however we do not fully understand how this has arisen. In this review article James Clark discusses how genome dynamics and gene loss contribute to genome evolution and the generation of diversity and complexity. He explains how genome evolution is non-homogenous…
