Autophagy controls insect development and can be targeted for pest control in agriculture. In the present study, starvation‐induced autophagy is investigated in the insect species Spodoptera frugiperda. Bioinformatics analysis and a search of the EST database (http://bioweb.ensam.inra.fr/spodobase) identifies a putative ATG8 gene of S. frugiperda. To generate a biomarker of autophagosome, the DNA...
Apoptosis and autophagy play crucial roles during Bombyx mori metamorphosis and in response to various adverse conditions, including starvation. Recently, calpain, one of the major intracellular proteases, has been reported to be involved in apoptosis and autophagy in mammals. BmATG5 and BmATG6 have been identified to mediate apoptosis following autophagy induced by 20‐hydroxyecdysone and starvation...
Atg9 is a conserved multipass transmembrane protein with an essential role in autophagy. In Saccharomyces cerevisiae, it travels through the secretory pathway to a unique compartment, the Atg9 peripheral structures. These structures are then targeted to the phagophore assembly site (PAS), where they are proposed to help deliver membrane to the forming autophagosome. We used ‘in vivo reconstitution’...
Although several features of apoptosis and autophagy have been reported in the larval organs of Lepidoptera during metamorphosis, solid experimental evidence for autophagy is still lacking. Moreover, the role of the two processes and the nature of their relationship are still cryptic. In this study, we perform a cellular, biochemical and molecular analysis of the degeneration process that occurs in...
