Update: The SnRK1 kinase as central mediator of energy signalling between different organelles

/in , , , , /by

By Bernhard Wurzinger, Ella Nukarinen, Thomas Nägele, Wolfram Weckwerth, Markus Teige Abstract The evolutionary conserved SnRK1 kinase complex is a key regulator in adjusting cellular metabolism during starvation, stress conditions and growth promoting conditions. Over the last two decades extensive genetic evidence for a widespread SnRK1 signalling network has accumulated. It is now well established […]

Self Reflection: A Leadership and Management series by early-career plant scientists

/in , , , , , /by

Science is a rewarding career, but challenges those who pursue it because the road to a permanent position is long and fragmented. Not surprisingly, many of the early-career researchers we’ve spoken to say they’d like to see more advice and resources to help them navigate their career path. With this in mind, we’ve started a […]

Focus Issue: Cellular Dynamics

/in , , , , , /by

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 […]

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

/in , , , /by

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 […]

MutS-Homolog2 silencing generates tetraploid meiocytes in tomato (Solanum lycopersicum)

/in , , , /by

Plant Direct. DNA repair occurs by several independent mechanisms, one of which is the mismatch repair (MMR) pathway. In prokayotes, MutS is a component of the mismatch repair pathway; homologous proteins in eukaryotes are known as MSH (MutS homologs). Sarma et al. set out to develop a hypermutable tomato strain (for genetic screening) by silencing […]
