Region covered by area codes 601 and 769. Area codes 601 and 769 are the telephone area codes for central Mississippi. The main area code, 601, was one of the original area codes implemented in 1947, and served all of Mississippi.n 1999, area code 662 was created in the northern half of Mississippi, including the Mississippi side of the Memphis area. The 1999 split was intended as a long-term solution, but within five years 601 was close to exhaustion due to the proliferation of cell phones, particularly in the Jackson area.
Lichen is the product of a symbiotic relationship between a fungus and a photosynthetic organism, usually a photosynthetic bacteria or algae.
1 Lichens are fungi that live in a symbiotic association with an autotrophic green alga or cyanobacterium (the photobiont) or â in some cases â both. 2  The fungal partner (the mycobiont) in most lichens (98% of them) is an ascomycete. Some live in a mutually beneficial symbiotic relationship with another organism, often a plant. 2  The association of fungus and plant root is called a mycorrhiza. 3  Some 80% of land plants benefit from symbiotic mycorrhiza. 4  The plant benefits by more-efficient mineral (especially phosphorus) uptake.
