Cadmium is a toxic metal in our environment. Bruno et al. explored cadmium-mediated root-growth inhibition using the model plant Arabidopsis thaliana. Cadmium affects root growth longitudinally by reducing root meristem cell number and radially by controlling the number and width of stele cells. The…

Fungal invasion exploits plant cell membrane trafficking components. For instance, plant immunity against fungi such as Vlumeria graminis f.sp. hordei (Bgh) is defined through two stages: pre- and post-invasive immunity. Nielsen et al. found that Vacuolar Protein Sorting 9a (VPS9a) acts as a guanine…

ARMADILLO-REPEAT KINESIN 1 (ARK1) promotes microtubule disassembly and NIMA-RELATED KINASE 6 (NEK6) organizes microtubule arrays. Previous studies showed that NEK6 interacts with ARK1 through Armadillo-repeat (ARM) cargo domain. Eng et al. looked at two constructs: one which lacks ARM (ARK1▲ARM-GFP)…

Chickpea is a highly cultivated member of the legume family, mostly in India, Australia, Pakistan, Turkey, Burma, Iran, Canada and the US. The detrimental threat for chickpea is the invasion of Ascochyta blight, which is caused by the fungal pathogen Ascochyta rabiei (formerly known as Phoma rabiei).  The…

Nuclear accidents in recent years such as the Fukushima incident during the tsunami in 2011 revealed the detrimental effects of leaked radioactive cesium (Cs) in environmental soil and water. Due to Cs's chemical similarity with potassium, an essential macronutrient for plants, cesium is taken up by…

DNA sequencing was slow before the development of high throughput sequencing. Portable DNA sequencing, which would make sequencing on-site a reality, was impossible until recently. Parker et al. report on the on-site use of MinION from Oxford Nanopore Technologies for DNA barcoding, which yields data…

Tardieu et al. have written a comprehensive and very readable overview of the current state and future challenges of plant phenomics, which they define as “the development and application of the suite of tools and methods used for three major goals — (1) capturing information on structure, function…

A diet consisting of a wide range of plant matter is optimal for human heath, but due to various historical and social factors (including the relatively high cost of fresh fruit and vegetables), many people don’t get the nutrients they need. Biofortification of staple foods like rice through breeding…
