Review: Plant evolution driven by interactions with symbiotic and pathogenic microbes (Science)

One of the great questions in plant science has been, “How do plants recognize friend from foe?” Like most great questions, this one benefits from a historical perspective. In their new review, Delaux and Schornack look at plant evolution through the lens of plant interactions with symbiotic and pathogenic microbes. The first part of this […]

CO2 diffusion in tobacco: a link between mesophyll conductance and leaf anatomy (Interface Focus)

Three key factors affect a plant’s ability to fix carbon: enzymatic activity of Rubisco, stomatal conductance, and the journey from sub-stomatal cavity to Rubisco, also known as mesophyll conductance (gm). This latter is the focus of this new work by Clarke et al. They delightfully compare this journey to that of Princess Leia from Star […]

Review: Time to wake up: Epigenetic and small-RNA-mediated regulation during seed germination Seed germination is a crucial step in plants’ life cycle and has critical implications in ecological and agronomic contexts. Therefore, there has been an increasing interest in understanding the mechanisms that prevent or trigger this process. Here, Luján-Soto and Dinkova provide a thorough […]

Review: On tree longevity (New Phytol)

Everyone enjoys hearing about ancient trees that have been alive since various events in human history, but did you ever stop to wonder why some trees live for millennia and others don’t? If so, you’ll want to read this Tansley Review by Piovesan and Biondi. One of their first observations is that in principle, trees […]

Three-dimensional reconstructions of haustoria in two parasitic plant species in the Orobanchaceae (Plant Physiol)

Parasitic plants form haustoria, which are specialized multicellular structures that penetrate into their host’s vasculature and act as conduits for nutrients.  The molecular and genetic contributors to haustorium development and function are well described. Here, Masumoto et al. have provided new insights into haustorium formation and structure through 3D reconstruction of serial thin (1 micron) […]
