Latest Endosymbiont Stories
MOFFETT FIELD, Calif., Aug.
A NASA-funded study suggests humans might not exist today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes. Biologist James Lake of the UCLA Center for Astrobiology compared proteins present in more than 3,000 different prokaryotes -- a type of single-celled organism without a nucleus -- and discovered two major classes of relatively simple microbes fused together more than 2.5 billion years ago. That endosymbiosis, or merging of two cells, he said,...
Humans might not be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes, NASA-funded research has found.
For pea aphids, the ability to go forth and multiply can depend on a single gene, according to new research.
The smallest collection of genes ever found for a cellular organism comes from tiny symbiotic bacteria that live inside special cells inside a small insect.
WASHINGTON (Reuters) - A one-celled creature found on a sandy beach may be in the process of kidnapping and incorporating an even tinier plant to use as a living energy source, Japanese researchers reported on Thursday.
Aphids or greenfly, plant lice (superfamily Aphidoidea) are small plant-feeding insects (1 to 10 mm). Of the 4,000 species of known aphids (distributed in 10 families), around 250 are serious pests for agriculture and forestry as well as an annoyance for gardeners. Natural predators include ladybirds, hoverfly larvae and lacewings. Aphids have two compound eyes and two ocular tubercles made up of 3 lenses, each of which is located behind and above the compound eyes. They have 2 tarsal...
