|Plant Biochemistry is the study of different chemical reactions in the plant such as photosynthesis, respiration, interaction between biomolecules and other plant specific biochemical processes. Research on Plant biochemistry focuses on the analysis of all the internal activities of plants and fundamental understanding of protein functions in plant so as to manipulate gene function in turn to get desirable compounds. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
