Details
Executive Summary : | North East (NE) region of India has a rich treasure of various Citrus species and among those, sweet orange is most widely grown across the globe while, Khasi mandarin is another citrus variety having high commercial value. Citrus tristeza virus (CTV) is one of the most devastating pathogens which is transmitted by aphid. NE region of India is considered as probable origin of CTV and its vector. Hence there is an urgent need to identify the CTV resistant genotypes, develop CTV disease free planting material in commercial citrus variety and identification of the molecular basis of CTV resistance. Calmodulin-binding Transcription Activators (CAMTAs) are major transcription factors involved in regulation of gene expression under several biotic and abiotic stresses across plant species. Recent studies in citrus depicted involvement of CAMTAs in abiotic stresses only. Present study can decipher the involvement of citrus CAMTA genes and promoters in CTV infestation. |

Achievements : | Survey was conducted to assess Citrus tristeza virus (CTV) incidence across Meghalaya, Tripura, and Arunachal Pradesh with Meghalaya showing the highest incidence rate followed by Arunachal Pradesh and Tripura. In Meghalaya, 9 villages across 5 districts were surveyed. RiBhoi district's Sohkhwai village recorded maximum with 100% CTV incidence, while Umsohme village had the lowest (57.14%). In Tripura, eight villages were surveyed, of which, Darjeeling Bari and Thelakumb showed the highest incidence (60%), while four villages reported no CTV presence. In Arunachal Pradesh, Rengging village, East Siang District and Kamba, Anjaw District, exhibiting the highest incidence (54.54%), followed by Bodak, East Siang District and Supliang, Anjaw District.
