Abstract

Eleven Pseudomonas isolates of ten-plant species collected from all over Tamil Nadu were compared for their total cell proteins separated through sodium dodecyl sulphate poly acrylamide gel electrophoresis. AH the isolates showed marked variations among themselves and between fluorescent and non-fluorescent groups. However, similarity was observed with respect to three protein bands with molecular weight of 46, 43 and 32kDa. Data were scored based on the presence or absence of protein bands and cluster analysis was performed. The isolates from same location viz., Coimbatore (PF1, PB2, COP1 and COT1), Sankaran Kovil (PSK1 and PSK2) and host (rice) showed greater level of similarity and occupied same cluster groups.

Abstract

Fungal antagonists were tested in vitro against the growth of the pathogen Altemaria solani (Ell. and Mart.), and in tomato plants against the leaf blight disease. Although Trichoderma harzianum followed by T. viride were significantly effective in inhibiting the mycelial growth or A. solani. there was no significant difference between the effcctiveness of Trichoderma species in pot culture studies.

Keywords
