We recognize the hard work that goes into scientific discovery, and the significant challenges faced by those at the beginning of their research career: low pay, long hours, and job insecurity. And yet, without graduate students and postdocs, science would grind to a virtual halt. As publisher and a professional society, ASPB is actively seeking […]

By Amna Mhamdi and Scott Hayes They say you can get too much of a good thing, and for plants that is certainly true. Light is essential for growth, but excessive light causes an overloading of the plant’s photosynthetic machinery. This excess energy can spill out and, through formation of reactive oxygen species (ROS), damage […]
Plants use diverse strategies for salt tolerance, including regulated transport of several different ions and production of compatible organic solutes. In April 2018, a workshop was held to discuss strategies for breeding salt tolerance in plants, with a focus on the energy requirements of various strategies. Some specific approaches for improving salinity tolerance in crops […]
We often think about how the soil environment influences plants, but two new papers focus on how plants influence the soil environment (through abiotic and biotic effects), in turn affecting other plants. These plant-soil feedbacks (PSFs) can be negative (resource depletion, natural enemy accumulation) or positive (resource deposition, mutualist accumulation). Bennett et al. summarize these […]
Plant cells have polarity, with the distribution of the auxin transporter protein PIN2 being a well-described example. Glanc et al. investigated how polarity is re-established following cell division. The authors showed that during cytokinesis, protein trafficking is directed towards the central cell plate (site of the new cell wall), but afterwards PIN2 relocalizes to its […]
Vegetative shade affects the ratio of red (R) and far-red (FR) light; relative to sunlight, the R/FR ratio is decreased due to absorbance of photosynthetically-active R light by other leaves. Low R/FR ratios cause increased elongation of shaded plant stems and petioles, as the plants strive to raise their photosynthetic tissues above those of their […]
This paper is kind of fun because it explores plant leaf and petal shape from an engineering perspective, identifying “fundamental mechanistic insights into how nature invokes mechanics in the evolution of commonly found shapes in plant organs by differential growth.” For each organ, the authors empirically determine growth strain profiles and the parameters β and […]
