Autophagy is a pathway in eukaryotes by which nutrient remobilization occurs through bulk protein and organelle turnover. Autophagy not only aides cells in coping with harsh environments but also plays a key role in many physiological processes that include pollen germination and tube growth. Most autophagic components are conserved among eukaryotes, but phylum-specific molecular components also exist. We show here that Arabidopsis thaliana PTEN, a protein and lipid dual phosphatase homologous… CONTINUE READING
