A scientist from Centre of the Region Haná for Biotechnological and Agricultural Research involved in paper published by prestigious journal Nature
Prestigious journal Nature published in April 2012 a paper “A novel putative auxin carrier family regulates intracellular auxin homeostasis in plants”. In preparation of this paper was also involved dr. Pěnčík from Centre of the Region Haná for Biotechnological and Agricultural Research, department of growth regulators in cooperation with other colleagues from the Palacký University and other institutions.
Auxin is a key hormone regulating plant growth and development. Directed transport of auxin between cells is mediated by auxin-efflux carriers called PINs. Authors identified a previously unknown auxin-transporter family called PIN-LIKES (PILS). These transporters, located in the endoplasmic reticulum, regulate intracellular auxin accumulation and metabolism and maintain cellular auxin homeostasis. These findings suggest that compartmentalization of auxin is important for developmental processes.
Dr. Pěnčík performed analysis of auxin content in Arabidopsis thaliana and discussed the data.
