Study was designed to examine the biochemical and molecular changes in chickpea (Cicer arietinum L.) in response fusarium wilt disease (Fusarium oxysporum f.sp. ciceris) in Gujarat condition in India. This book therefore, provides information to design experiment with histopathological, biochemical and molecular techniques for wilt pathogen and host tissues. This book also gives nice pictures of host pathogen interaction in root tissues of chickpea with Fusarium wilt pathogen. It is very usefull for plant biochemist, plant pathologist and molecular biologist. Standardize methodology of Aminoacids Analyzer, phenolics with HPLC, Native Acidic and Basic protein with SDS protein estimation, DNA extraction to RAPD marker and Antioxidant, hydrolytic and oxido-reductase enzymes with techniques for Chickpea plant. The book also provides different stages of disease development for wilt pathogen in chickpea. This experiment is useful for primary proteomics and biotechnological work in molecular biochemistry of host and pathogen in plants.
