Evolution of organelles
WebEndosymbiosis is universally accepted to have played a major role in the evolution of eukaryotes (most obviously, in the origin of cellular organelles such as mitochondria and plastids), but genomic analyses have given rise to the hypothesis that the origin event itself was a symbiotic merger of two (or more) cells. WebSep 13, 2024 · Cadmium is a well-known elicitor of melatonin synthesis in plants, including rice. However, the mechanisms by which cadmium induces melatonin induction remain elusive. To investigate whether cadmium influences physical integrities in subcellular organelles, we treated tobacco leaves with either CdCl2 or AlCl3 and monitored the …
