New. Phytol. Ustilago maydis causes corn smut disease on maize which is characterized by plant cancerous symptoms forming tumours on all aerial parts of host. The fungus deploys organ-specific effector proteins to re-program organ primordia to enormous tumours, however the cellular dissection of these…

Plant Physiol. Extracellular ATP induces plant defense responses but the mechanisms involved are largely unknown. The paper by Tripathi et al. shows how extracellular ATP serves as a danger signal in plant defense and its interaction with the signalling pathways of other stress hormones, e.g. jasmonate…

Nature. Cuscuta sp. commonly known as dodder, is an obligate parasitic plant that colonizes a broad range of host plants and obtain water and nutrients by specialized feeding structure called haustorium.  Literature suggests that this specialized structure is involved in bidirectional movement of viruses,…

Science. As our ecosystems are changing rapidly, more studies are needed to document them. One of these important events is “coral bleaching”, a phenomenon that occurs due to environmental stress and when coral hosts lose their algal symbionts or zooxanthellae (Symbiodinium spp.), showing the white…

PLOS Biol. Guard cell size is, in general, inversely related to stomatal density. It is advantageous for plants to maximize their photosynthetic capabilities by generating higher rates of gas exchange, thereby incorporating more CO2 to help drive this pathway. However, the number of cells that can occupy…

Guest Editor: Dr. Amey Redkar Amey is a postdoc at The Sainsbury Laboratory, Norwich, UK and has been a Plantae Fellow since September 2017. He is working to understand the interaction of plants and pathogens during disease development. His current research which is funded by EMBO Long Term Fellowship…

Dinoflagellates in the genus Symbiodinium have the ability to enter into endosymbiotic associations with corals, providing the metabolic basis for the highly productive and biologically diverse coral-reef ecosystems, as well as with other cnidarians, including sea anemones and jellyfish. The Symbiodinium-coral…

Boron (B) is an essential micronutrient for plant growth and development. Its major physiological function is to maintain the structure of the cell wall by crosslinking pectic polysaccharides through borate-diol bonding of two rhamnogalacturonan II molecules. B is immobile in most plant species. Therefore,…
