From friend to threat: the mutualist-pathogen transition of plant-fungal interaction is determined by a small gene cluster
Plant Science Research WeeklyThe infection modes of microbes in hosts can be reversible and can range from pathogenic to mutualistic, depending on the environmental conditions. The plant-associated fungus Colletotrichum tofieldiae (Ct) has been shown to promote primary root growth and increase shoot fresh weight of Arabidopsis in…
A large effect genetic trade-off is caused by a single mutation in CBF2
Plant Science Research WeeklyUnderstanding the genetic basis of local adaptation of a species is an important but thorny problem. Now that whole genomes are readily characterized, it’s not hard to see lots of differences between populations, but pulling meaning and demonstrating functional consequences out of those differences…

WWR Full PostReview: Rapid auxin signaling: Unknowns old and new
You 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…
Putting conservation gardening on the map
Plant Science Research WeeklyWe’re living in a time of increasing awareness of environmental degradation, but this awareness is often not accompanied by opportunities for direct actions. Here, Munschek et al. describe conservation gardening (growing endangered native plants) as a strategy by which people can support local biodiversity.…
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.

NAC-CYP Mediates Soybean Nodule Senescence
The Plant Cell: In a NutshellYu et al. show that activation of the expression of cysteine protease genes by GmNAC039 and GmNAC018 is required for soybean nodule senescence The Plant Cell (2023).
