Variability in production of extracellular enzymes and toxin by Phomopsis vexans

S Pan, S Bhagat - Annals of Plant Protection Sciences, 2014 - indianjournals.com
Ann. Pl. Protec. Sci. 22 (2): 422-460 (September, 2014) 439 many black pycnidia which may
be scattered or arranged in concentric ring (Sharma et al., 2011). The pathogen P. vexans
had a very restricted host range, its enzymatic activity do not appear to be very strong,
possibility of toxin production-a toxin that played a very important role in pathogenesis and
disease development was a distinct possibility. The present investigation was aimed to
establish enzyme activity and production of toxins by different isolate of P. vexans in vitro …

Variability in production of extracellular enzymes and toxin by Phomopsis vexans.

SP Sitansu Pan, S Bhagat - 2014 - cabidigitallibrary.org
Variability among 5 isolates of Phomopsis vexans [Diaporthe vexans](BhSPv, BSPv, GgSPv,
KbFPv and TnSPv) in pectic and cellulase enzyme production in vitro was studied in
modified Richard's synthetic medium amended with 0.5 citrate pectin and water-soluble
carboxymethylcellulose-Na salt. Variability among the isolates with respect to toxin
production was also studied by using 3 different media, ie Czapeck Dox, Richard's synthetic
and modified Fries 3 solutions. The in vivo activity of pectic and cellulase enzymes was …
