“…The number of SsnpPR1 (18) family members identified in this study was lower than that in Hordeum vulgare (20) [8], Glycine max (24) [20], Solanum tuberosum (22) [21], and Triticum aestivum (86) [13]. In contrast, the number of SsnpPR1s was higher than that in Piper nigrum (11) [22], Triticum durum (12) [12], Musa acuminate (15) [23], Allium sativum (16) [24], and Camellia sinensis (17) [25]. The possible reason behind the expansion of PR1 family members might be gene duplication events, which include two major driving forces (tandem and segmental) for the duplication of gene families in plants, particularly in sugarcane [5].…”

“…The caveolin-binding motif and CAP-derived peptide (CAPE) are present in the conserved CAP domain of the PR-1 protein [ 10 ]. Previously, PR-1 family members have been systematically identified and characterized in different plant species, such as 10 in Mangifera indica [ 11 ], 12 in Triticum durum [ 12 ], 20 in Hordeum vulgare [ 8 ], and 86 in Triticum aestivum [ 13 ]. A growing body of research has shown that PR1 proteins are essential for plants’ defense against biotic stressors [ 7 ].…”

Plant resistance against biotic stressors is significantly influenced by pathogenesis-related 1 (PR1) proteins. This study examines the systematic identification and characterization of PR1 family genes in sugarcane (Saccharum spontaneum Np-X) and the transcript expression of selected genes in two sugarcane cultivars (ROC22 and Zhongtang3) in response to Ustilago scitaminea pathogen infection. A total of 18 SsnpPR1 genes were identified at the whole-genome level and further categorized into four groups. Notably, tandem and segmental duplication occurrences were detected in one and five SsnpPR1 gene pairs, respectively. The SsnpPR1 genes exhibited diverse physio-chemical attributes and variations in introns/exons and conserved motifs. Notably, four SsnpPR1 (SsnpPR1.02/05/09/19) proteins displayed a strong protein–protein interaction network. The transcript expression of three SsnpPR1 (SsnpPR1.04/06/09) genes was upregulated by 1.2–2.6 folds in the resistant cultivar (Zhongtang3) but downregulated in the susceptible cultivar (ROC22) across different time points as compared to the control in response to pathogen infection. Additionally, SsnpPR1.11 was specifically upregulated by 1.2–3.5 folds at 24–72 h post inoculation (hpi) in ROC22, suggesting that this gene may play an important negative regulatory role in defense responses to pathogen infection. The genetic improvement of sugarcane can be facilitated by our results, which also establish the basis for additional functional characterization of SsnpPR1 genes in response to pathogenic stress.
