Hydrogen peroxide (H2O2) is an important signal involved in diverse stress responses both intracellularly and extracellularly, but until now it hasn’t been clear how the plant recognizes it. Wu et al. used a genetic screen to search for plants that fail to produce a calcium influx response in the presence…

For many years, the Arabidopsis transgenic allele ice1-1 was used to demonstrate the role of the transcription factor ICE1 in freezing and cold tolerance. This gene was first identified in a screening strategy using a luciferase reporter for DREB1A expression, another TF involved in downstream signaling.…

Many trees emit isoprene (C5H8, a small volatile carbon compound) during hot weather, and isoprenes have been shown to help trees tolerate short bursts of high temperatures (heat flecks). Isoprenes are not themselves harmful, but are reactive and can lead to the production of high levels of ground-level…

Plant Science Research Weekly: February 14 February 14, 2020/in Blog, WWR Full Post /by Mary Williams Review: Deep learning for plant genomics and crop improvement One of the goals of plant science is to use the molecular phenotype (genome, transcriptome, proteome) to predict the…

Plants have strategies to cool themselves when the temperature is hot. These include increasing their rate of transpirational cooling through stomatal opening and raising their leaves, which can enhance air flow. Previous studies have shown a role for the heat shock proteins (HSPs) and their cochaperone…

Urban gardens are a great way to introduce people to plant science, to bring fresh food into areas underserved by grocery stores (“food deserts”), and can promote a sense of community. But as Cooper et al. observe, many potential sites can be contaminated with heavy metals (lead, cadmium) and metalloids…

Water and nutrient availability are a major limiting factors for plant productivity. Plant have evolved a series of complex adaptive features that help them to survive in the hostile environment. Upregulation of lignin biosynthetic genes in roots under salt and water stress have been reported in some…
