Formation and regeneration of protoplasts in Sclerotium rolfsii ATCC 201126.
AIMS Different cultural conditions for forming and reverting protoplasts were systematically studied to establish a rapid and efficient protocol for Sclerotium rolfsii ATCC 201126. METHODS AND RESULTS Osmotic stabilizer, lytic enzymes and mycelial age were the main factors influencing protoplast yields. An optimized protocol involving 1-h hydrolysis of 45-h-old mycelium with Trichoderma harzi...
متن کاملIsolation and fusion of protoplasts from the phytopathogenic fungus sclerotium rolfsii(sacc.)
Sclerotium rolfsii (Sacc.) is a serious plant pathogenic fungus and lacks perfect (basidial) stage in production. Protoplast fusion technology was employed to reconstruct fusants from this fungus. Two strains designated as A and R were used. Maximum protoplast yields of 3.8x10(5)/g mycelia and 2.8x10(5)/g mycelia were formed in strains A and R respectively. Osmotic stabilizer sucrose 1M gave ma...
متن کاملPhenolic Acid Changes in Mycelia of Sclerotium rolfsii After Garlic and Onion Supplementation in a Broth Medium
High performance liquid chromatographic (HPLC) analysis of mycelia of Sclerotium rolfsii grown in broth medium supplemented with garlic (Allium sativum) and onion (Allium cepa) was carried out to estimate qualitative and quantitative changes in phenolic acids. Several phenolic acids, such as gallic, chlorogenic, ferulic, o-coumaric and cinnamic acids were detected in varied amounts in mycelia g...
متن کاملSHOOT REGENERATION FROM PROTOPLASTS OF PENNISETUM AMERICANUM L (MIL CEREAL)
A finely dispersed cell suspension was obtained from embryogenic calli of two genotypes of pearl millet (Pennisetum americanum L. Mil cereal). Protoplasts isolated from both cell suspensions divided and produced globular embryoids and calli. On an agar medium, the embryoids were induced to form albino shoots or albino plantlet- like structures
