Stressing the translatome: It is about time

Bonnot and Nagel explore how heat stress affects the circadian-regulated translatome at different times of day. Titouan Bonnot1 and Dawn H. Nagel1 1Department of Botany and Plant Sciences, University of California, Riverside, Riverside, California, USA Background: The plant circadian clock synchronizes…

Misexpression of a MADS-box gene results in longer glumes and grains in wheat

Adamski et al. reveal that the expression of a MADS-box transcription factor is the basis for a grain phenotype observed in Polish wheat. Plant Cell https://doi.org/10.1093/plcell/koab119 By Cristobal Uauy and Nikolai M Adamski John Innes Centre, Norwich NR4 7UH, United Kingdom Background:…

KARRIKIN INSENSITIVE2-dependent signaling in the liverwort Marchantia polymorpha

Mizuno et al. show that genes in the KARRIKIN INSENSITIVE2-dependent signaling pathway are conserved in the liverwort Marchantia polymorpha and control early development of the thallus. Yohei Mizuno and Junko Kyozuka Background: Plants hormones play crucial roles in growth and development. Karrikins…

Keeping an “i-on” chloroplast gene expression

DeTar et al. examined whether disruption of ion homeostasis affects plastid gene expression and chloroplast development. Rachael Ann DeTar and Hans-Henning Kunz both at School of Biological Sciences at Washington State University & Plant Biochemistry at LMU Munich Background: Proteins that…

Sde1A enables axillary meristem formation at the leaf axil boundary

By Hernán López and Klaus Theres, Max Planck institute for Plant Breeding Research.  López and colleagues identify the gene mutated in the tomato super determinant (sde) mutant, which affects vegetative shoot branching, but not seed set. Background: The degree of shoot branching is an important…

NF-YCs mediate plant growth during the dark-to-light transition

Zhang et al. uncover the roles of NF-YC transcription factors in repressing brassinosteroid biosynthesis and signaling to mediate photomorphogenesis in Arabidopsis. Background: Seedlings, which germinate in the soil, generally undergo rapid hypocotyl elongation to seek light for growth and development.…
