Given the high costs and limited efficiency of traditional biological methods, developing cost-effective and accurate computational models for LPI prediction becomes essential.

Subsequently, we introduce a hypernode (randomly generated node) to establish a heterogeneous hypergraph integrating lncRNAs and proteins, thereby capturing richer node representations. Finally, we predict LPIs using a multilayer graph convolutional network (GCN) combined with a fully connected (FC) layer.

However, due to its long-term wild status, its value has not been fully exploited and utilized, especially regarding the mitochondrial genome, which is crucial for plant growth activities, there have been no relevant studies and reports so far. RESULTS: In this study, we sequenced and assembled the complete mitochondrial genome of C. giganteum and elucidated its evolutionary trajectory and phylogenetic relationships. The C. giganteum mitogenome has a multi-chromosomal structure containing 19 circular molecules. The assembled mitogenome has a total length of 2,066,679 bp and a GC content of 44.54%. A total of 37 unique protein-coding genes (PCGs), 16 tRNA, and three rRNA genes were annotated. Several repetitive sequences and sequence fragments homologous to chloroplasts have also been found in the C. giganteum mitogenome. To determine the evolutionary and taxonomic positions of C. giganteum, we constructed a phylogenetic tree using C. giganteum mitochondrial PCGs.

This aphid species comprises several biotypes, each one capable of feeding and reproducing on a limited range of specific legume species. However, little is known about the transcriptional response of the plants to different aphid biotypes. To investigate pea defense mechanisms against the pea-adapted and pea non-adapted A. pisum biotypes, we analyzed the transcriptional responses by mRNA sequencing of six pea genotypes with contrasting resistance levels and different haplotypes at the ApRVII locus. This locus confers partial resistance to the pea-adapted and non-adapted A. pisum biotypes. Transcriptomic analyses of pea genotypes with and without aphid infestation revealed 9,217 differentially expressed genes in pea genotypes infested with the pea-adapted aphids, while fewer genes, 1,561 genes total, were expressed in response to the pea non-adapted aphids. Both aphid biotypes activated immune responses and the biosynthesis of secondary metabolites, including flavonoids. However, the pea-adapted biotype appeared to suppress multiple pathways associated with photosynthesis, cell wall biosynthesis, fatty acid metabolism, and other growth-related processes. Candidate genes potentially involved in aphid resistance were identified both within and outside of the ApRVII locus. These findings provide insights into pea resistance mechanisms against both pea-adapted and pea non-adapted A. pisum biotypes, as well as the ability of the adapted biotype to modulate pea defenses leading to host susceptibility, and pave the way for follow-up studies, including metabolomic analyses.</p>","PeriodicalId":9030,"journal":{"name":"BMC Genomics","volume":"26 1","pages":"580"},"PeriodicalIF":3.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211313/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
