Article Synopsis
  • High-light stress negatively impacts agricultural productivity in subtropical and tropical regions due to damage and reduced growth.
  • Research shows that the beneficial microbe Enterobacter sp. SA187 can help Arabidopsis thaliana thrive under high-light stress by lowering harmful reactive oxygen species and supporting photosynthesis.
  • SA187 activates key genes related to iron metabolism and redox regulation, improving the plant's antioxidative systems, with ethylene signaling playing a crucial role in enhancing these benefits.

Land plants have to face an oxidizing, heterogeneous, and fast changing environment. Redox-dependent post-translational modifications emerge as a critical component of plant responses to stresses. Among the thiol oxidoreductase superfamily, class III CC-type glutaredoxins (called ROXYs) are land plant specific, and their evolutionary history is highly dynamic.

Developmental and environmental constraints influence genome expression through complex networks of regulatory mechanisms. Epigenetic modifications and remodelling of chromatin are some of the major actors regulating the dynamic of gene expression. Unravelling the factors relaying environmental signals that induce gene expression reprogramming under stress conditions is an important and fundamental question.

Soil calcium carbonate (CaCO) impacts plant mineral nutrition far beyond Fe metabolism, imposing constraints for crop growth and quality in calcareous agrosystems. Our knowledge on plant strategies to tolerate CaCO effects mainly refers to Fe acquisition. This review provides an update on plant cellular and molecular mechanisms recently described to counteract the negative effects of CaCO in soils, as well as recent efforts to identify genetic bases involved in CaCO tolerance from natural populations, that could be exploited to breed CaCO-tolerant crops.

Article Synopsis
  • Pearl millet is highly resilient to heat and drought, making it a key food source in the sub-Saharan Sahel region where its root traits help with establishment in tough conditions.
  • Research shows that the plant's fast-growing primary root is crucial for early drought tolerance, which is vital for agricultural success in the Sahel.
  • Genetic studies identified a specific glutaredoxin gene linked to root growth and stress resilience, indicating that this gene plays a significant role in helping pearl millet adapt to its harsh environment.
