Abstract :

Brinjal or eggplant (Solanum melongena L.) is an important and widely consumed indigenous vegetable crop of India grown round the year. Among the diseases, Brinjal Little leaf (BLL) is one of the most important economic diseases caused by phytoplasma, belonging to the class mollicutes, under which wall less prokaryotic organisms are grouped. The diseased plants showed characteristic symptoms including little, narrow, soft, glabrous and smooth leaves produced as clusters, phyllody, proliferation of axillary shoots along with shortened internodes, stunted growth etc. Graft inoculation was 100% successful and initial symptoms were noticed in the new sprouts of the rootstock 7-10 days after the graft transmission. The molecular detection was done through PCR and it produced an amplification of ~1.8 kb with the primer P1/P7.
