When we speak about rice, we’re often referring to one of two domesticated species, Oryza japonica or Oryza indica. However, there are an additional 25 species in the genus Oryza. These so-called wild relatives harbor substantial genetic diversity that holds promise for crop improvement. Here, Prakash…

As the hottest year on record, 2023 has truly been a global annus horribilis during which humans, other animals, and domesticated and wild plants have faced unprecedented environmental challenges. In the past month alone, torrential rainfalls have wreaked havoc in Asia, the Middle East, and many parts…

Salt is a massive problem for most land plants. At the macroscopic level, excess soil salinity can cause stunting or death. At the molecular / cellular level, salinity causes both osmotic and ionic challenges that affect membrane homeostasis, molecular interactions, and protein stability. A new review…

Meet the newest member of the Teaching Tools in Plant Biology family, The Floral Transition and Adaptation to a Changing Environment: from Model Species to Cereal Crops, by Michela Osnato. Freely available in the November 2022 issue of The Plant Cell. You can download the resources here, from the supplemental…

Biodiversity contributes to thriving, healthy ecosystems that are essential for climate tolerance, improving water quality and habitat structure. As time goes on, there is increasing pressure to address climate change concerns worldwide, with one possible climate change mitigation approach being reforestation…

To better understand plant responses to different environments, Lou et al. compared Arabidopsis thaliana accessions derived from Sichuan (high precipitation/regular flooding) and Tibet (arid) to isolate genetic adaptations towards flooding stress. The two accessions showed divergent phenotypes: the Sichuan…
