3. Applications of biotechnological tools in citrus improvement: A review
Main Article Content
Abstract
Citrus species (Rutaceae) are known worldwide due to their wide range of fruits having high nutritional value. Other valuable products obtained from citrus are volatile organic compounds and essential oils, which are used in food as well as in aroma and flavor industries. Biotechnological interventions have played key role in improvement of citrus in accordance with the consumer demand and increasing fruit range consumption. In this review, some key aspects of biotechnology for improvement of citrus i.e. genetic transformation, cryopreservation, tissue culture propagation, doubled haploid production and somatic embryogenesis are discussed. This article also revealed various genes inserted through genetic engineering to control citrus diseases, insect pests, early flowering induction, salt and drought tolerance etc.
