Sorghum downy mildew (SDM) caused by the oomycete, Peronosclerospora sorghi, is one of the destructive diseases that afflict maize. P. sorghi infects a susceptible host, hindering its growth and altering its morphology. To understand the molecular basis of the compatibility interaction between P. sorghi and maize, a comparative proteomic approach (2D-PAGE) was employed between the mock-inoculated (control) and SDM-inoculated leaves in the susceptible genotypes of maize (UMI79 and CM500).

Leaf blight was observed in anthurium crop in Tamil Nadu and Kerala states of India during 2011-2012. Initially, the symptoms were small circular to irregular brown spots with concentric rings on the leaves that gradually enlarged. Fungal isolates, obtained from infected leaf tissues were grown in pure culture and on the basis of cultural and morphological characteristics and ribosomal DNA spacer sequences, the organism was identified as Alternaria alternata (Fr.) Keissler. To our knowledge this is the first report of Alternaria leaf blight disease in Anthurium andraeanum in India.
