ASSESSMENT OF CONTRIBUTION OF FOLIAR TRICHOMES TOWARDS ALLELOPATHY
Plant trichomes vary in their structure, extents and cellular composition. Some forms, commonly known as glandular trichomes, contain a bulk of specific (secondary) metabolites of diverse nature. Trichomes are connected with various adaptive processes which include protection against herbivores and pathogens as well. Since trichomes jut from the epidermis and can frequently be smoothly isolated from it and gathered, the mRNAs, proteins and other molecules that they contain are remarkably open to investigation. This property marks them exceptional trial frameworks for distinguishing proof of the enzymes and pathways in charge of the synthesis of the particular metabolites produced by these structures and in some cases somewhere else in the plant. Our study investigates the allelopathic contribution of structures present on the leaf surface of Nicotiana plumbaginifolia Viv. against seedling growth of Cicer arietinum L. The infusion obtained after dipping Nicotiana leaves in Dichloromethane (DCM) for 10 s was the most phytotoxic among all the infusions. The observed inhibition in Cicer growth was not only dependent on type of infusion but also the concentration. Glandular trichomes were most dehydrated at 10 s in DCM, suggesting their role for the observed allelopathy. Such study on the biochemistry of trichomes and their phytotoxicity may develop them highly valuable objects for plant metabolic engineering.
