Callose deposition during pollen development

Madeleine Seale University of Oxford maddy.seale@plants.ox.ac.uk Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new paper investigating pollen formation in cotton (Gossypium hirsutum), we now know that a pollen-specific protein…

Zones of Defense? SA Receptors Have it Under Control

The constant evolutionary arms race with pathogens has equipped plants with a layered immune system. As the first line of defense, membrane-localized pattern recognition receptors perceive microbe-associated molecular patterns and activate pattern-triggered immunity (PTI). In parallel, R proteins –…

Plant Physiology welcomes 16 new Assistant Features Editors

At the beginning of 2018, Plant Physiology initiated a program to introduce several promising early-career scientists to the editorial board and engage their expertise in assessing and writing about research published in the journal. Over the past three years, these scientists brought their passion for…

Hi @anavalladares @CPFreed @LauraMejia92 @rah107 @CPFreed@Humberto_Herrera, thank you so much for making up the fantastic infographics for FOPD! I am making up this post to compile them and what the social media text will look like. I will make up an article with all of them in Open Forum…

An evolutionary perspective on LysM receptors reveals conserved mechanisms for microbial signal perception

Lena Maria Müller Boyce Thompson Institute Lena.Mueller@miami.edu Plants are in constant contact with millions of microbes, which can be pathogenic or establish mutualistic interactions with the plant. One well-studied mutualistic interaction is the nodulation symbiosis of legumes with nitrogen-fixing…
