Spermine deficiency shifts the balance between jasmonic acid and salicylic acid‐mediated defence responses in Arabidopsis

open access: yesPlant, Cell &Environment, Volume 46, Issue 12, Page 3949-3970, December 2023., 2023
Abstract Polyamines are small aliphatic polycations present in all living organisms. In plants, the most abundant polyamines are putrescine (Put), spermidine (Spd) and spermine (Spm). Polyamine levels change in response to different pathogens, including Pseudomonas syringae pv. tomato DC3000 (Pst DC3000). However, the regulation of polyamine metabolism

RNA‐dependent RNA polymerase 1 delays the accumulation of viroids in infected plants

open access: yesMolecular Plant Pathology, Volume 22, Issue 10, Page 1195-1208, October 2021., 2021
Downregulation of RDR1a in tomato increased susceptibility to PSTVd infection; severe leaf curling with vein necrosis occurred in TRV:SlRDR1a tomato compared with TRV:00 tomatoes 28 days postinoculation (dpi) with PSTVd. Abstract RNA‐dependent RNA polymerase 1 (RDR1) is essential for plant antiviral defence, but its role in plant defence against viroid
