Review. Mycorrhizal symbiosis: Genomics, ecology, and agricultural application

This outstanding Tansley review by Martin and van der Heijden spans the scale of research on mycorrhizal symbiosis from molecules to ecosystems, and spans time from the earliest encroachment of plants and fungi onto land to the future applications of our understanding. This very comprehensive review is a great resource to anyone with an interest […]

Seasonal flowering and seasonal growth measure light duration differently

One of the first lessons a plant biologist learns is that many plants coordinate their seasonal flowering through measuring daylength, and that this process involves both photoreceptors and the biological clock that functions inside of cells. Of course, daylength also affects plant metabolism, in part by changing the amount of light received for photosynthesis, but […]

Review: Integrating cellular electron microscopy with multimodal data to explore biology across space and time Fifty years ago (1974), Albert Claude, Christian de Duve, and George Palade were awarded the Nobel Prize for their discoveries on the structural and functional organization of the cell, which Claude eloquently framed by writing, “We have entered the cell, […]

Review. Autophagy: A key player in the recovery of plants from heat stress

Plants have a remarkable ability to adapt to stress. For many stresses, plants respond to short-term mild exposure by becoming more tolerant to subsequent harsher stresses that would otherwise be lethal; this effect is known as priming. Priming occurs through several mechanisms that can include changes to metabolism, accumulation of transcription factors or miRNAs, and […]

Receptor-associated kinases control lipid provisioning in plant–fungal symbiosis

Most plants benefit from symbiotic associations with fungi, in which the fungi aid in nutrient update particularly of phosphate, and the plant returns the favor by supplying the fungi with lipids. Several but not all of the molecular players required for these important pathways have been identified. Here Ivanov and Harrison have uncovered additional components, […]

Convergent evolution in pitcher plant traps reveals a mechanism for composite trait evolution

It’s easy for most of us to grasp how an enzyme evolves new functions or substrate specificities, but envisioning how something incredibly complex like the human eye can be quite challenging (even Darwin was stumped). In this fascinating paper, Chomicki et al. asked how two geographically separated carnivorous pitcher plants evolved the same complex trap […]

Review: A century of studying plant secondary metabolism—From “what?” to “where, how, and why?”  Phytochemicals, also known as plant secondary metabolites, play primary roles in plant development, structure, and response to the environment. Their metabolism has been studied for over a century. In a new review, Dixon and Dickinson discuss past and recent advances in […]

Review: Stem cells for crop improvement

Plants, like animals, have small populations of stem cells capable of differentiating into other tissues, but in plants these stem cell populations are even more long-lived and versatile. Stem cells in plants include the meristems (shoot and root apical meristems, inflorescence and axillary meristems) as well as the vascular cambium. Collectively, they produce all the […]

Review. Milestones in understanding phosphorus uptake, transport, sensing, use, and signaling Phosphorus (P) is an essential nutrient and critical component of nucleic acids, phospholipids, and other molecules. Yang et al. provide a historical (since 1996) overview of the processes controlling its uptake and use. Plants take up P from the rhizosphere primarily in the form […]
