AI Article Synopsis
- The study focused on isolating and characterizing specific species (spp.) to test their effectiveness against GBNV (Groundnut Bud-Nicotiana Virus) in tomato plants.
- Among the three inoculation methods (pre-, post-, and simultaneous), pre-inoculation with liquid consortia showed the lowest disease severity index (DSI) and significantly reduced the GBNV infection rates in both pot culture and field trials.
- The interaction analysis indicated that these species can enhance the tomato plant's resistance through the upregulation of defense genes, suggesting they are effective for managing GBNV in tomatoes.
Article Abstract
Unlabelled: In the present study, spp. were isolated, characterized, and the efficacy was tested against (GBNV) in tomato. Among the three inoculation methods viz., pre-, post-, and simultaneous inoculation, tested for antiviral efficacy, pre-inoculation spray of the three spp. viz., and (SAT1, SAT4, and STR2) recorded the least disease severity index (DSI) of GBNV in tomato. In the pot culture, seed treatment of liquid consortium of three spp. @ 2 ml/g of seeds along with seedling dip at 10 ml/lit followed by soil drenching at 10 ml/lit on 7 days after transplanting (DAT) and foliar application at 0.5% on 15 DAT, 30 DAT, and 45 DAT recorded the least GBNV infection of 15% DSI and 16.67% DSI in trial I and II respectively. Besides, under field conditions, the disease incidence was reduced to 14.44% recording a higher yield of 76.67 t/ha in the treated plants against 63.99 t/ha in control. Upregulation of defense genes viz., PR1, PR2, PR6, WRKY, MAPKK, and NPR1 during tripartite interaction between tomato, , and GBNV was analyzed by qRTPCR, indicating that the consortia could decrease the virus severity through induced systemic resistance pathways. Thus, it is concluded that spp. can be used for the management of GBNV in tomato.
