Analysis of metabolic pathways related to fertility restoration and identification of fertility candidate genes associated with Aegilops kotschyi cytoplasm in wheat (Triticum aestivum L.)

Abstract: Background: Thermo-sensitive male-sterility based on Aegilops kotschyi cytoplasm (K-TCMS) plays an important role in hybrid wheat breeding. This has important possible applications in two-line hybrid wheat breeding but the genetic basis and molecular regulation mechanism related to fertility restoration are poorly understood. In this study, comparative transcriptome profiling based on RNA sequencing was conducted for two near-isogenic lines comprising KTM3315R and its sterile counterpart KTM3315A, a total of s… Show more

“…Transcriptome analysis unveiled a set of DEGs implicated in the regulation of defense responses, potentially influencing stress response mechanisms and regulate secondary metabolism. Consistently, preceding studies highlighted primary biological process categories encompassing cellular process, metabolic process, biological regulation, and response to stimulus terms [ [34] , [35] , [36] , [37] ]. Certain genes, such as Germin-like protein subfamily T member 1 ( GLP1 ), Monoterpene synthase 7 ( TPS7 ), alpha-terpineol synthase ( ATESY_VITVI ), and Pathogenesis-related genes transcriptional activator ( PTI5 ), exhibited notably upregulated expression levels.…”

“…Pollen/fruit ripening is a complex biological process involving physiological, structural and numerous molecular changes (Osorio et al, 2013;Li et al, 2019). In this study, proteomics and metabolomics were used to study the changes of protein and metabolites content during the ripening process in pollen and poplar flocs of P. deltoides.…”

“…Sporopollenin is a type of biopolymer mainly composed of polyhydroxy aliphatic compounds and phenols [ 51 , 52 ] that exists in the pollen and spores [ 53 ] and is the main component of the pollen exine skeleton [ 22 ]. Flavonoids have key roles in pollen development and are essential for pollen maturation and pollen tube growth in flowering plants [ 54 ]. In another pathway, cytochrome P450s (P450s) are methylated monooxygenases involved in a large number of biosynthetic pathways in secondary and primary metabolism [ 55 ].…”
