Plants have a clever chemical called salicylic acid that acts like an alarm system when attackers arrive. In the common lab plant Arabidopsis, scientists first mapped out how this alarm works: a special route called the isochorismate pathway makes salicylic acid, proteins named NPR bind to it, an
Plants have a clever way to fight off viruses. They use a system called SAR, which stands for systemic acquired resistance. SAR acts like a plant's immune system, helping it remember past infections and protect itself better in the future. Salicylic acid (SA) and its friends, like MeSA and AzA, are
Plants have their own ways of staying healthy. Two key players in this defense system are ATG6 and NPR1. ATG6 is a gene linked to a process called autophagy, which helps plants break down and recycle their own components. NPR1, on the other hand, is a master regulator that coordinates the plant's im
Grapevines, especially the wild ones, are tough cookies. They can handle diseases and stress better than most plants. This is partly because of tiny molecules called microRNAs, or miRNAs, which help control how the plant grows, develops, and fights off invaders. One such miRNA, miR3398, has a specia
Imagine you're a plant facing an invading pathogen. Just like we have an immune system, plants have their own defenders – NLR proteins. When they sense trouble, these proteins gather together to form higher-order structures called resistosomes. These resistosomes are crucial in fighting off intruder
