Extra protection To prevent that everything and everyone can just entre plant roots have an extra lignin layer to protect their vascular tissue. But lots of plants have in addition to this protecting ring another barrier. Now a group of international researchers show in Nature Plants how plants are regulating this barrier. Plant roots containContinue reading “Extra protection”

Shredding dead cells for protection
Shredding dead cells for protection Interestingly microbes are not colonising the root tip. Now researchers show in eLife that is because the tip protecting root cap is actively shredding death cells. Microbes are actively colonising plant roots. Except the growth centre containing tip of the root, which stays free of microbes. The root tip isContinue reading “Shredding dead cells for protection”
Loaded defence
Loaded defence Using an electric current to prevent infections. It sounds strange, but that it works show researchers from England in Scientific Reports. There is not much that works against infections of Phytophthora palmivora, an oomycete pathogen. But so discovered the researchers, when exposed to an electric field the oomycete swim towards the positive electrodeContinue reading “Loaded defence”
Deciphering stress reactions
Deciphering stress reactions At first glance a plants reaction to many stressors appear to be identical. Still each stressor elicit a specific response. Now German researchers show in Nature using light-gated calcium and anion channels that the difference is in the tiniest detail of the reaction. In studies with animal cells, researchers are using themContinue reading “Deciphering stress reactions”
