“…NOOT shares 77% identity and 85.6% similarity with BOP2. NPR1 participates in salicylic acid-mediated plant defense against necrotrophic pathogens (Pieterse and Van Loon, 2004;Fu et al, 2012). By contrast, the Arabidopsis bop1 bop2 double mutant develops blade-on-petiole structures and is altered in flower formation (Hepworth et al, 2005;Norberg et al, 2005).…”

During their symbiotic interaction with rhizobia, legume plants develop symbiosis-specific organs on their roots, called nodules, that house nitrogen-fixing bacteria. The molecular mechanisms governing the identity and maintenance of these organs are unknown. Using Medicago truncatula nodule root (noot) mutants and pea (Pisum sativum) cochleata (coch) mutants, which are characterized by the abnormal development of roots from the nodule, we identified the NOOT and COCH genes as being necessary for the robust maintenance of nodule identity throughout the nodule developmental program. NOOT and COCH are Arabidopsis thaliana BLADE-ON-PETIOLE orthologs, and we have shown that their functions in leaf and flower development are conserved in M. truncatula and pea. The identification of these two genes defines a clade in the BTB/POZ-ankyrin domain proteins that shares conserved functions in eudicot organ development and suggests that NOOT and COCH were recruited to repress root identity in the legume symbiotic organ.

“…When SAR is induced, monomeric NPR1 is formed, which accumulates in the nucleus and activates the expression of PR genes [20]. In addition to its role in SAR, NPR1 functions in crosstalk between SA-and JA-dependent defense signaling pathways (review see [28]). NH1 appears to have a similar role as NPR1.…”

“…The Non-expressor of Pathogenesis-Related 1 (NPR1) gene is a defence response cotranscriptor conferring resistance to a wide range of pathogens during the establishment of systemic acquired resistance (SAR) and induced systemic resistance (Pieterse and van Loon 2004;Wally et al, 2009). This is due to the ability of NPR1 to activate various forms of antimicrobial Pathogenesis-Related (PR) genes (Cao et al, 1994;Glazebrook et al, 1996;Cao et al, 1997;Yuan et al, 2007;Canet et al, 2010;Shi et al, 2010).…”

Differences between the coding sequences of two banana homologues of the Non-expressor of Pathogenesis-Related 1 (NPR1) genes (MNPR1A and MNPR1B) were investigated as a possible cause for the differential activity of the two genes. Each of the MNPR1 coding sequences were expressed under the control of the cauliflower mosaic virus 35S promoter/terminator sequences in the transgenic Arabidopsis npr1-2 mutant. These MNPR1-expressing plants were then exposed to either the biotrophic oomycete Hyaloperonospora arabidopsidis, the necrotrophic fungus Botrytis cinerea, or the hemi-biotrophic bacterial pathogen Pseudomonas syringae. Expression of either MNPR1A or MNPR1B increased 2 Pathogenesis-related 1 (PR-1) transcription in a similar manner in mutant plants and reduced pathogen growth, restoring resistance of the Arabidopsis npr1-2 mutant plants to pathogens.Sequence differences between MNPR1A and MNPR1B coding sequences did not affect MNPR1activity, suggesting a possible role for the involvement of other regulatory sequences in differential MNPR1 gene expression.
