Gene duplication and aneuploidy trigger rapid evolution of herbicide resistance in common waterhemp

Plant Physiol. Herbicide resistance is a serious problem in contemporary agriculture. One of the most widely used herbicides, glyphosate, interferes with the activity of EPSPS (5-enolpyruvylshikimate-3-phosphate synthase). Koo et al. previously showed that glyphosate-resistant waterhemp (Amaranthus tuberculatus, a common weed in agricultural fields) has an increased copy number of the EPSPS gene and an extra […]

Maize adaptation to higher latitudes has been facilitated by transposon activities.

Proc. Natl. Acad. Sci. USA. Flowering is a major determinant of crop adaptation to new environments. Starting from its tropical origins and requirement for short-day conditions to flower, natural selection and breeding have allowed maize to adapt to long-day environments and thus be grown over a wider range of latitudes, from Canada to Chile. Nevertheless, […]

Ten simple rules for biologists learning to program

PLOS Comp. Biol. Plant biologists need basic programming skills (see Friesner et al. for a discussion of why this is true and how to achieve it).  As part of the “Ten Simple Rules” series in PLOS Computational Biology, Carey and Papin describe Ten simple rules for biologists learning to program. This article seeks to encourage […]

Review: Declining oxygen in the global ocean and coastal waters ($)

Science. Oxygen levels have been declining in oceans since the middle of the 20th century, largely because of global warming phenomena and human-driven nutrient enrichment of coastal regions. These effects have enhanced microbial oxygen intake, altering the cycles of nutrients and carbon, and lowering oxygen solubility and rates of oxygen atmospheric resupply in some areas. […]

Focus Issue: Cellular Dynamics

Plant Physiology has released a focus issue on the topic of Cellular Dynamics, which includes Updates on topics ranging from Actin Dynamics to Wall Growth. The Editorial by Szymanski, Bassham, Munnik, and Sakamoto provides an excellent overview of the current state our understanding of plant cell dynamics. As they observe, “Discovering and unraveling the complexity […]
