Strategies for Enhancement in Food Production Test - 8

Alternate source of proteins for animals and human nutrition is single cell protein. Microbes are grown on industrial scale as source of good protein. Microbes like Spirulina on waste water of potato processing plants.

Mushrooms are eaten by many people and large scale mushroom culture is a growing industry. It is a rich source of protein and other micronutrients.

Hybrid vigour is mostly due to heterozygosity of traits. The hybrid contain genome from both the parents that make them more vigorous.

Norin-10 gene is used to obtain dwarf varieties of crops like rice and wheat. This gene is introduced in crop plants by using technique of genetic engineering.

Spirulina is single celled algae that can be easily grown in starch containing medium life waste water from potato processing plants. It contains high quantity of protein that can be easily used by human beings.

The ability to generate a whole plant from any cell/explant is called totipotency. Tissue culture method is used to generate whole plant from plant parts.

Bio-fortification is the breeding of crops with higher levels of vitamins and minerals to improve public health. Nutritional quantity is increased for protein, vitamins and minerals.

The process of growing whole plants form any part of plant (explant) is called tissue culture. In this process part of plant is grown in test tube under sterile condition in special nutrient.

The method of producing thousands of plants through tissue culture is called micro-propagation. All these plants will be genetically identical to original plant from which they are grown.

plant tissue culture is the technique of in vitro maintaining and growing cells, tissue or organs in nutrient medium. Tissue culture technique was first performed successfully by White in 1932.
