Global climate change affects weather patterns, and excess soil salinity harms plant growth. Previous studies have shown interaction between the circadian clock and salt responses. In normal conditions, the core circadian clock oscillator GIGANTEA (GI) sequesters the SOS2 kinase, part of the salt-overly…

Nitrogen (N) is vital for plant growth, with plants typically absorbing inorganic N compounds like nitrate (NO3−) and ammonium (NH4+) from the soil. Yet plants can also utilize organic N sources, including amino acids like glutamine (Gln). Gln, as the first organic N compound assimilated within plant…

Plants have a remarkable ability to reprogram and regenerate as needed following wounding. This trait is invaluable not only to gardeners but also to regenerate plants following genome editing. Here, Wang, Zhai, Wu, and Deng have identified key steps in tissue regeneration. Through characterization of…

Many animals such as corals and sea slugs host photosynthetic symbionts. Several studies have investigated how the host and symbiont coordinate their activities. This new study by Sarfati et al. explores how symbiotic green algae and their animal host, the flattened-worm Convolutriloba longifissura,…

Plants recruit beneficial microbiomes in the rhizosphere in response to aboveground pathogen infections, a mechanism known as “cry for help.” Zhang and Liu et al. investigated this effect to test whether pathogenicity is necessary for assembling a disease-suppressive rhizomicrobiome. By using nonpathogenic…

Most readers recognize the photograph of the amazing nitrogen-fixing maize, with its red, slimy aerial roots that nurture nitrogen-fixing bacteria. But I suspect few of us have thought about how this landrace came to the attention of the mainstream media, who owns the rights to it, and how it would be…

Review: Strategies to improve photosynthesis Photosynthesis is the process by which plants assimilate carbon by using light energy. However, with the solar energy conversion efficiency of many crop plants less than 1%, it is inefficient. Therefore, there is interest in manipulating photosynthesis…
