and Alternaria brassicae on Mustard Leaf: A Histopathological Study]]>SharmaPratibha DeepSwati BhatiDinesh SinghSharmaManika ChowdappaP. 22014132Alternaria blight caused by Alternaria brassicicola
(Schwein) Wiltshire and Alternaria brassicae (Berk) Sacc. is one
of the most serious diseases of Cauliflower [Brassica oleracea (L.) var.
botrytis] and Mustard [Brassica juncea L.] grown as edible vegetable
and oilseed crop, respectively in India. As resistance against these pathogens
is not found till now therefore, the exploration of the host-pathogen interaction
is much needed. In the present study, the cauliflower-A. brassicicola and
mustard-A. brassicae interactions were studied at microscopic level using
light and electron microscope. The initial infection processes involve conidia
germination, penetration and colonization on the plant surfaces. Several germ-tubes
developed from conidia and colonize extensively across the leaf surfaces. Penetration
in the plant surface, either directly through the epidermis or via stomata occurred
with occasional appressoria formation. Least aggressive A. brassicae
isolate was found to infect mustard leaf by spreading over epidermal cells only.
Finally, hyphae colonize the leaf cells forming network collapsing epidermal
cells to form necrotic lesions which may be due to release of toxin.]]>Abul-Fazal, M., M.I. Khan and S.K.
