Botany Syllabus for GATE 2015 Examinations:
Plant Systematics: systems of classification (non phylogenetic vs phylogenetic – outline), plant groups, molecular systematics.
Plant anatomy: plant cell structure, organization, organelles, cytoskeleton, cell wall and membranes, anatomy or root, stem and leaves, meristems, vascular system, their ontogeny, structure and functions, secondary growth in plants and stellar organization.
Morphogenesis & Development: cell cycle, cell division, life cycle of an angiosperm, pollination, fertilization, embryogenesis, seed formation, seed storage proteins, seed dormancy and germination.
Concepts of cellular totipotency, clonal propagation, organogenesis and somatic embryogenesis, artificial seed, somaclonal variation, secondary metabolism in plant cell culture, embryo culture, in vitro fertilization.
Physiology and biochemistry: plant water relations, transport of minerals, and solutes, stress physiology, stomatal physiology, signal transduction, N2 metabolism, photosynthesis, photorespiration, respiration. Flowering: photoperiodism and vernalization, biochemical mechanism involved in flowering, molecular mechanism of senencensce and aging, biosynthesis, mechanism of action and physiological effects of plant growth, regulators, structure and functions of Biomolecules, (proteins, carbohydrates, lipids, nucleic acid) enzyme kinetics.
Genetics: principles of mendelian inheritance, linkages, recombination, genetic mapping, extrachromosomal inheritance, prokaryotic and eukaryotic genome organization, regulation of gene expression, gene mutation and repair, chromosomal aberrations (numerical and structural) transposons.
Plant Breeding and Genetic Modification: Principles, methods selection, hydrization, heterosis, male sterility, genetic maps and molecular markers, sporophytic and gametophytic self incompability, haplodiy, triploidy, somatic cell hybridization, marker assisted selection, gene transfer methods viz. direct and vector – mediated plastid transformation, transgenic plants and their application in agriculture, molecular pharming, plantibodies.
Economic Botany: A general account of economically and medicinally important plant- cereals, pulses, plants yielding fibres, timber sugar, beverages, oils, rubber, pigments, dyes, gums, drugs and narcotics. Economic importance of algae, fungi ,lichen and bacteria.
Plant Pathology: nature and classification of plant diseases, diseases of important crops caused by fungi, bacteria and viruses and their control measure, mechanisms of pathogenesis, and resistance, molecular detection of pathogens, plant and microbe beneficial interactions.
Ecology and Environment: ecosystems – types, dynamics, degradation, ecological succession, food chains and energy flow, vegetation types of the world, pollution and global warming, speciation and extinction, conversation strategies, crypreservation, phytoremediation.
