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 [...]
In this article we will discuss about the quaternary pollen records in different places of India. It was Huntington (1906) who initiated the pollen analysis in India from the sediments of Pangong Lake in Ladakh. Later, Wodehouse (1935), De Terra & Paterson (1939) worked out palynologically Indian Quaternary sediments. The investigations on pollen analysis to establish the Quaternary vegetation history, [...]
