Induction of Rhizophagy by yeast Saccharomyces cerevisiae in roots of lettuce Lactuca sativa

Abstract

Abstract This work is part of a scientific project that aims to study the effect of adding yeast (Saccharomyces cerevisiae) on growth, productivity and nutritional value of two varieties of lettuce (Lactuca sativa), planted in a hydroponic system. Here we extend experimental approaches to detect the Rhizophagy process induced by added S.cerevisiae to hydroponic nutritive solution. An Laboratory anatomical study was conducted to detect and investigate the occurrence of Rhizophagy phenomenon induced by yeast cells. Results showed that the yeast cells aggregate around the root cells of lettuce, and then enter the cells, followed by digestion and disappearance.
