Fused protoplast (left) with chloroplasts (from a leaf cell) and coloured vacuole (from a petal) Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid. [1]
Hybrids may also be produced by a technique called protoplast fusion. In this case protoplasts are fused, usually in an electric field. Viable recombinants can be regenerated in culture. Chemical mutagens like ethyl methanesulfonate (EMS) and dimethyl sulfate (DMS), radiation, and transposons are used for mutagenesis. Mutagenesis is the ...
A parasexual cycle is initiated by the fusion of hyphae (anastomosis) during which nuclei and other cytoplasmic components occupy the same cell (heterokaryosis and plasmogamy). Fusion of the unlike nuclei in the cell of the heterokaryon results in formation of a diploid nucleus ( karyogamy ), which is believed to be unstable and can produce ...
This is also the most common pathway of artificially induced polyploidy, where methods such as protoplast fusion or treatment with colchicine, oryzalin or mitotic inhibitors are used to disrupt normal mitotic division, which results in the production of polyploid cells. This process can be useful in plant breeding, especially when attempting to ...
Protoplast (from Ancient Greek πρωτόπλαστος (prōtóplastos) 'first-formed'), is a biological term coined by Hanstein in 1880 to refer to the entire cell, excluding the cell wall. [ 1 ] [ 2 ] Protoplasts can be generated by stripping the cell wall from plant , [ 3 ] bacterial , [ 4 ] [ 5 ] or fungal cells [ 5 ] [ 6 ] by mechanical ...
Tennessee state Sen. Ken Yager, 77, was caught on camera stumbling around as troopers tried to make him walk in a straight line on Jekyll Island in Georgia at about 5 p.m. Tuesday.
This connection is often brought on by the psychological stress of a new cancer diagnosis, the existential dread of facing death, and the strain this disease places on relationships.
Kathleen Mary Drew-Baker (6 November 1901 – 14 September 1957) was an English phycologist.She was known for her research on the edible seaweed Porphyra umbilicalis (), which led to a breakthrough for commercial cultivation.
