Since its ebook in 2000, Biochemistry and Molecular Biology of crops, has been hailed as a huge contribution to the plant sciences literature and significant acclaim has been matched via worldwide revenues good fortune. preserving the scope and concentration of the 1st variation, the second one will offer a big replace, comprise a lot new fabric and reorganise a few chapters to extra enhance the presentation.
This publication is meticulously organised and richly illustrated, having over 1,000 full-colour illustrations and 500 pictures. it truly is divided into 5 components protecting: cubicles, phone copy, strength movement, Metabolic and Developmental Integration, and Plant atmosphere and Agriculture. particular adjustments to this variation include:
- Completely revised with over half the chapters having a tremendous rewrite.
- Includes new chapters on sign transduction and responses to pathogens.
- Restructuring of part on mobile copy for more advantageous presentation.
- Dedicated web site to incorporate all illustrative material.
Biochemistry and Molecular Biology of Plants holds a different position within the plant sciences literature because it presents the one accomplished, authoritative, built-in unmarried quantity ebook during this crucial box of study.
