Plant biochemistry is an important emerging field in the agricultural sciences. Basic knowledge of the chemistry and the biochemical mechanisms of the plant in synthesizing various components is essential for advancements needed in other areas of agriculture like plant breeding, plant protection, plant production, etc. In the recent past, biotechnology and biochemistry are moving hand in glove to solve many problems related to humans and other living beings. The book is aimed at providing good information to graduate and post-graduate students in agriculture and biology. It will also serve as a reference book to researchers in plant breeding, agronomy, plant physiology and plant protection and will come in handy to solve many global problems by the present and future generations.
