Micro-Propagation of Ornamentals and Tree Species | Biotechnology

Plant propagation is carried out by sexual or asexual mode of life cycles. The asexual or vegetative reproduction produces genetically identical plants. Multiplication of several horticulturally important crops follows vegetative methods. Production of genetically identical plant cultivars by asexual method is called clonal propagation and genetically identical indi­viduals derived from a single individual by asexual mode referred as clone. Contrast [...]

Organization of Chloroplast DNA | Biotechnology

Structural organization of chloroplast is signified by the presence of double membrane envelope and soluble phase, the stroma, and an internal membrane system, the thylakoids. Both thylakoid and stromal systems are committed for light reaction and carbon dioxide fixation respectively. Chloroplast attains diversified shapes. Higher plants exhibit lens shaped chloroplasts in their cytosol. The size measures anywhere between 5 and [...]
