Role of polyamines in vegetable crop production: A review

Abstract

Vegetables play a major role in human diet. They are enriched with various essential nutrients and therefore also called as protective food. For sustainable vegetable production and to meet the vegetable demand advancement in production techniques of vegetable crops is need of an hour. Use of polyamines as a tool for improving the vegetable production is found to be beneficial. Polyamines are the organic poly-cation compounds consisting of two or more amino groups found to improve growth and development of plants due to their effects on cell division and cell differentiation. Polyamines are also involved in various physiological processes in plants and also play major role in ion channels regulation and transportation of different molecules in cell membrane. Polyamines are associated with many fundamental processes such as DNA replication, RNA modification, synthesis of protein, modulation of enzyme activities and transcription in plants. Several studies have been conducted to study the effect of different polyamines (putrecine, spermidine, spermine etc.) on growth and development of vegetables for better outcome. Therefore, present review paper focuses on compilation of literature with respect to the effect of polyamines on growth and development of vegetables for sustainable and fruitful vegetable production.
