Kamburupitiya, 1998) Sapumohotti, W.P.Nitrate reduction mutants (nit- mutants) were selected from 33 isolates of Fusarium oxysporum isolated from asparagus plantings showing reddish brown rot symptoms in Malaysia. These nitrate reduction mutants were used in complementation tests for vegetative compatibility. Nine vegetative compatibility groups (VCGS) were identified, but most (19) isolates fell into 4 VCGs that were found at more than one location. There was no strong interrelationship between VCG and location. However, seven isolates were identified as vegetatively self- incompatible based on their inability to form heterokaryons between complementary nit- mutants.Item Micropropagation of two endemic threatened Cryptocoryne species of Sri Lanka(Faculty of Agriculture University of Ruhuna, 2008) Herath, H.M.I.; Krishnarajah, S.A.; Wijesundara, D.S.A.Item Cloning and sequencing of the Fur gene from marine probiotic Alteromonas aurantia A18 and its possible role in siderophore production(Faculty of Agriculture University of Ruhuna, 2008) Junfeng, L.; Hirimuthugoda, N.Y.; Hongfang, Li; Shumin, Y.
