This research utilised six sorghum restorer lines, six sorghum sterile lines, and 36 hybrid combinations created through the NCII incomplete double-row hybridisation method. We evaluated the performance of F1 generation hybrids for leaf photosynthesis-related parameters, carbon metabolism-related enzymes, and their correlation with yield traits during the flowering stage. Results showed that hybrid sorghum exhibited significant high-parent heterosis in net photosynthetic rate (P n ), transpiration rate (T r ), stomatal conductance (G s ), apparent leaf meat conductance (AMC), ribulose-1,5-bisphosphate (RuBP) carboxylase, phosphoenolpyruvate (PEP) carboxylase, and sucrose phosphate synthase (SPS). Conversely, inter-cellular carbon dioxide concentration (C i ), instantaneous water uses efficiency (WUE), and sucrose synthase (SuSy) displayed mostly negative heterosis. Traits such as 1000-grain weight (TGW), grain weight per spike (GWPS), and dry matter content (DMC) exhibited significant high-parent heterosis, with TGW reaching the highest value of 82.54%. P n demonstrated positive correlations with T r , C i , G s , RuBP carboxylase, PEP carboxylase, GWPS, TGW, and DMC, suggesting that T r , C i , and G s could aid in identifying high-photosynthesis sorghum varieties. Concurrently, P n could help select carbon-efficient sorghum varieties due to its close relationship with yield. Overall, the F1 generation of sorghum hybrids displayed notable heterosis during anthesis. Combined with field performance, P n at athesis can serve as a valuable indicator for early prediction of the yield potential of the F1 generation of sorghum hybrids and for screening carbon-efficient sorghum varieties.</p>","PeriodicalId":12483,"journal":{"name":"Functional Plant Biology","volume":"51 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142079870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An experiment was carried out to evaluate the viability of chilli cultivation in waterlogged areas, based on physiological and biochemical responses using floating agriculture. Eight different chilli varieties were subjected to floating agriculture in two different agronomic seasons.

Among the different varieties, Sakata 653 in summer and Jhilik in winter responded better than others.

The first stress was applied in plants at the vegetative stage for 5days and involved either dehydration or waterlogging, depending on the treatment. Subsequently, the plants were irrigated or drained and maintained at pot capacity until the second stress. For the second stress, the conditions were repeated in plants at the reproductive stage.

Under waterlogging and dehydration, priming and cross-priming significantly increased the activity of antioxidant enzymes and the levels of TSS, amino acids, and proline while reducing H2 O2 concentration and lipid peroxidation.

Here, we analysed and identified 17 PYL genes in the potato genome, which were categorised into three groups based on phylogenetic analysis. These genes are distributed across nine chromosomes with predicted proteins subcellar localisation primarily in the cytoplasm. These StPYLs revealed conserved exon structures and domains among the groups. Promoter region analysis indicated hormone and stress-related elements in all StPYL s. Protein-protein interactions and microRNA networks predicted that the interactions of StPYLs are crucial components of ABA signalling, underlining their pivotal role in stress management and growth regulation in potato. Expression profiling across different tissues and under various stresses revealed their varied expression pattern. Further, we validated the expression pattern of selected StPYLs through reverse transcription quantitative PCR under drought, salt, and Phytophthora infestans stresses. This revealed consistent upregulation of StPYL6 in these stresses, while StPYL11 exhibited significant downregulation over time.
