Seed germination is a critical developmental switch that depends not only on stored mRNA but also on the selective translation of these transcripts. In this study, Wang et al. explored how translational control of some genes can fine-tune the timing of germination.  Using translation inhibitors and…

Salt stress can severely affect cotton (Gossypium hirsutum) productivity, especially during early growth. Cao et al. identified a molecular switch in cotton that fine-tunes responses to salt stress and the hormone abscisic acid (ABA), based on the reversible phosphorylation of the ABA signaling phosphatase…

Special Science Issue: Plants and Heat The June 12 issue of Science has a focus on plants and heat that includes several excellent review and research articles. In a very interesting review, Singh Yadav et al. discuss the complex and fascinating question of how plants sense temperature, emphasizing…

This year marks the 25th anniversary of the publication of the first genome sequence of a plant, Arabidopsis thaliana, (see https://doi.org/10.1038/35048692). As this review by Bevan et al. observes, this exciting accomplishment was met with some skepticism by those who felt that it was not likely to…

Most food crops are relatively intolerant to soil salinity, yet globally soils are becoming increasingly salinized. This excellent review by Raza et al. pulls together the myriad approaches that are being used to develop salinity-smart crops. It starts with an overview of how soil salinity affects crops…

Receptor-like kinases (RLKs) constitute a large family of membrane-bound proteins in plants. The Arabidopsis genome encodes over 600 RLKs, while the rice genome contains more than 1,000. RLKs are best known for their role in perceiving environmental stimuli and triggering downstream signaling pathways…

Mycorrhizal symbiosis is widespread in nature, occurring in approximately 90% of terrestrial plant species, and played a crucial role in enabling plant colonization of land over 450 million years ago. The majority (>80%) of these associations are formed by endomycorrhizae, in which fungi from the…

Plant metabolism varies substantially between developmental stages, cell types, and intracellular environments. Similarly, biochemical responses to abiotic stress often deviate between neighboring cell types, but discerning what is changing where becomes more challenging in smaller and more fragile sub-compartments. …
