Cytokinin receptor CRE1 is required for the defense response of Nicotiana tabacum to Chilli veinal mottle virus

Comprehensive phytohormone metabolomic and transcriptomic analysis of tobacco (Nicotiana tabacum) infected by tomato spotted wilt virus (TSWV)

“…On the other hand, type A RRs act as repressors of the cytokinin-activated transcription ( Choi et al, 2011 ). Cytokinins can respond to abiotic and biotic stresses in plants, including viral infection ( Cortleven et al, 2019 ; Zhang et al, 2022 ; Zou et al, 2020 ). Zou and colleagues found that the CRE1-defective mutant plants display more severe symptoms caused by the Chilli veinal mottle virus (ChiVMV) compared with WT plants.…”

“…Zou and colleagues found that the CRE1-defective mutant plants display more severe symptoms caused by the Chilli veinal mottle virus (ChiVMV) compared with WT plants. Furthermore, viral load was significantly higher in CRE1-defective mutants ( Zou et al, 2020 ). We observed a significant increase in the content of cytokinin iP after TSWV infection ( Fig.…”
