Nitrogen fixing bacteria anabaena are found in which plant
Answers
Anabaena is a genus of filamentous cyanobacteria, or blue-green algae. It found as plankton. It is known for its nitrogen fixing abilities. They form symbiotic relationships with certain plants, such as the mosquito fern. Some species of Anabaena are endophytes. They live in the roots of Cycas and Azolla
Anabaena is found in all types of water. Blooms or massive growths can occur in waters with a lot of nutrients. These blooms discolor the water and give it a bad odor when the cells die and decay.
They are one of four genera of cyarlobacteria that produce neurotoxins. These toxins are harmful to local wildlife, as well as farm animals and pets. Production of these neurotoxins is part of its symbiotic relationships. It protects the host plant from grazing pressure.
A DNA sequencing project was undertaken in 1999. It mapped the complete genome of Anabaena. Its DNA is 7.2 million base pairs long. The study focused on heterocysts, which convert nitrogen into ammonia. Certain species of Anabaena have been used on rice paddy fields. They act as natural fertilizer.
