Management of pod borer, Helicoverpa armigera has been prominent among crop improvement programs. Lack of resistance sources in the cultivated germplasm and crossing incompatibility with pod borer-resistant wild relatives have prompted biotechnological interventions. Identification and exploitation of genes from pigeonpea wild relatives in host plant resistance towards the pod borer assumes pertinence. Dynamic transcriptome analysis of the wild relative vis a vis cultivated pigeonpea identified a CHI4 chitinase as one of the putative insect resistance genes. The study presents variations in important amino acids in CHI4 chitinases from C. cajan and its wild relative C. platycarpus. Comparative protein modeling and docking analysis of the two proteins demonstrated differences in substrate binding efficacy of the chitinase from C. platycarpus which resulted in a minimum binding energy of -a in tobacco. The CHI4 gene from C. platycarpus can be useful in the mitigation of H. armegira in pigeonpea as well as in other crops. © 2021 Society of Chemical Industry.Following solid organ transplantation, a substantial proportion of chronic allograft loss is attributed to the formation of donor-specific antibodies (DSAs) and antibody-mediated rejection (AbMR). The frequency and phenotype of T follicular helper (Tfh) and T follicular regulatory (Tfr) cells is altered in the setting of kidney transplantation, particularly in patients who develop AbMR. However, the roles of Tfh and Tfr cells in AbMR after solid organ transplantation is unclear. We developed mouse models to inducibly and potently perturb Tfh and Tfr cells to assess the roles of these cells in the development of DSA and AbMR. We found that Tfh cells are required for both de novo DSA responses as well as augmentation of DSA following presensitizat
