Genomic analysis of a lichen photobiont alga

Lichens are complex assemblies that are composed of at least two organisms, a fungus (the mycobiont) and a photosynthetic partner, the photobiont. Lichen lifestyles have emerged several times, and the photobiont can be either prokaryotic cyanobacteria or eukaryotic algae. Recently, Tagirdzhanova et al. carried out a genomic analysis of the photobiont isolated from the widespread […]

New tools to study an old mycorrhiza

I love learning about the many molecular adaptations that allowed plants to adapt to life on land, and particularly have enjoyed sharing the iconic micrograph from Remy et al (1994) that shows a 400 year old arbuscular mycorrhiza of the fungus Glomeromycotina  inside a cell of Aglaophyton major. Now, in a new study, Strullu-Derrien et […]

Review: A complete guide to metabolomics This review by Rai et al., part of a focus collection on metabolism, comprehensively covers the role of metabolomics in plant biology: its history, its tools and techniques, and its impact. As the authors point out, metabolomics bridge the gap between genotype and phenotype by providing a direct readout […]

How parasitic plants avoid being parasitized

It’s not too difficult to envision how a plant recognizes something very different from itself, like a bacterium, oomycete, or fungus. It’s a bit less obvious how a plant recognizes another plant as different from itself. This self-recognition is important when you think about parasitic plants, which break into their hosts through structures called haustoria […]

Review.When the sun becomes too hot: Non-photochemical quenching in plants Plant photosynthetic machinery can easily be overwhelmed by strong sunlight. Therefore, plants developed a set of processes called Non-Photochemical Quenching, a safety valve that dissipates excess light energy as heat. In a recent review, van Amerongen and Croce synthesize decades of often contradictory research to […]

A vision for plant science education

The urgent need to support and sustain plant research is indisputable, but sometimes plant education, the foundation upon which research rests, doesn’t get the same support. In January 2025, a group of dedicated educators (mostly higher education and outreach) spent two days together to strategize a vision for a secure, sustainable, and effective educational landscape.
