In this article we will discuss about the functions of tapetum. Many physiological functions have been accredited to the tapetum, but they all congregate on the ability of its cells to synthesize metabolites for the nourishment of microsporocytes, regulation of meiosis, pollen wall formation, synthesis of pollenkitt, etc. Experimental approach to establish tapetal function in a convincing way has come [...]
In this article we will discuss about the role of proteins in pollen grains. T. Singer and Petrovskya - Baranova (1961) were the first to show the existence of proteins with enzymatic properties in certain layers of the pollen walls of Paeonia and Amaryllis. Subsequently, Makinen and McDonald (1968) demonstrated the pollen enzymes and isoenzymes in flowering plants. The details [...]
The following points highlight the top five applications of pollen biotechnology: 1. Overcoming Pollination Constraints for Optimization of Crop Yield 2. Developing Effective Pollination Control System for Commercial Production of Hybrid Seeds 3. Overcoming Cross ability Barriers to Transfer of Useful Genes to Crop Species and Others. Application # 1. Overcoming Pollination Constraints for Optimization of Crop Yield: In majority [...]
