Organelle variation Often we assume that genes responsible for phenotypic variation resides in the nuclear genome. Now a group of international researchers show in PNAS that also genes located in organelles are contributing to phenotypic variation. Organelles like mitochondria and chloroplasts contain genetic material, remnants of ancient symbiotic ancestors. Genes essential for function of theContinue reading “Organelle variation”

Pressurised division
Pressurised division How a cell divides influences how a plant looks. A new study in Developmental Cell shows how the orientation of microtubules influences were the orientation of the dividing wall in the dividing cell. Due to their cell wall plant cells are connected to each other. In this way the orientation of a cellContinue reading “Pressurised division”
Skewing roots
Skewing roots Sometimes a study takes a different route than expected. Like the just in New Phytologist published study about phosphate and root skewing, that started as study towards tropism. Tropism is the actively growing towards or away from a source. The clearest you see this for plants in relation to gravity. Place them onContinue reading “Skewing roots”
Secret code
Secret code Sometimes old findings appear to be not completely correct. That was what a team of international researchers led by Christian Hardtke found out when they studied the brassinosteriods receptors more closely. Brassinosteroids are one of the plant hormones that have a hand in about everything that has to do with growth and development.Continue reading “Secret code”
