Variability in reproductive morphology of family Saprolegniaceae and its significance


Abstract:

The family Saprolegniaceae includes 17 genera, viz., Achlya Nees von Esenbeck, Aphanodictyon Huneycutt ex Dick, Aphanomyces deBary, Aplanopsis Höhnk, Brevilegnia Coker & Couch, Calyptralegnia Coker, Couchia W.W. Martin, Dictyuchus Leitgeb, Geolegnia Coker, Leptolegnia deBary, Phragmosporangium Seymour, Plectospira Drechsler, Protoachlya Coker, Pythiopsis deBary, Saprolegnia Nees von Esenbeck, Sommerstorffia Arnaudow and Thraustotheca Humphrey. The eighteenth genus with its type species named—Girishia indica Prabhuji has been added to this list and has been critically discussed. Girishia indica Prabhuji has been found to be a connecting-link between family Pythiaceae and Saprolegniaceae. The morphological variability of reproductive structures (vegetative, asexual and sexual) in all eighteen members of Saprolegniaceae has been described and their significance has been discussed and reviewed.
