Here we review the speciation patterns and genetic diversity of the birds from the Qinghai-Tibet Plateau in relation to the geological history and climatic changes. First, the uplift of the Qinghai-Tibet Plateau forms a geographic barrier and promotes interspecific and intraspecific genetic differentiation. Second, the uplift of the Qinghai-Tibet Plateau has provided new ecological niches for many endemic birds and facilitated their speciation. Third, the emigration and immigration of bird species between the Qinghai-Tibet Plateau and adjacent zoological regions have promoted species divergence, colonization and dispersal. Furthermore, Pleistocene glaciations and associated climate change drive postglacial colonization and lead to secondary contact, which influenced the genetic divergence of the conspecific populations and sister species. The multi-omics approach has increasingly been used in the studies on the ecological adaptive evolution of birds in Qinghai-Tibet Plateau. Future studies should focus on the role of geological and climatic factors in species differentiation, develop integrative approach with multi-omics methods, and explore the ecological mechanisms of high-elevation adaptation of plateau species. As an important region for biodiversity conservation, more efforts should be implemented to maintain the stability and sustainability of the Qinghai-Tibet Plateau and its ecosystem in light of global change.</p>","PeriodicalId":35536,"journal":{"name":"遗传","volume":"47 1","pages":"133-145"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142956101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the involvement of reactive oxygen species (ROS) in the process of wounding-induced archeospores formation and release was investigated. Based on ROS fluorescence observations, the blade fragments began to accumulate ROS after 12 h wounding, while no ROS signals were observed in normal blades. Next, when the blade fragments were treated with ROS inhibitor diphenyleneiodonium (DPI), it showed that the production of archeopores was significantly suppressed. Under normal culturing after wounding, 78.3% of the fragments could release archeospores, and the ROS fluorescence was enriched in the released archeospores. Under 0.05 μM DPI treatment, the percentage of fragments releasing archeospores was dropped to 16.2%, with decreased ROS fluorescence levels. Under 0.1 μM DPI treatment, no archeospores were released from the fragments, and ROS fluorescence was also undetectable in the fragments.

Here, we investigated the expression patterns and functions of the two <i>LFY</i> genes (<i>LFY1</i> and <i>LFY2</i>) in soybean. Both genes were predominantly expressed in unopened flowers and the shoot apical meristem, with <i>LFY2</i> having the higher transcript abundance.

The <i>lfy2</i> mutants showed obvious changes in floral organ morphology, but the <i>lfy1</i> mutants showed no obvious changes in floral organ morphology or pod development. The <i>lfy1 lfy2</i> double mutants displayed more serious defects in floral organ development than <i>lfy2</i>, resulting in complete sterility. Gene expression analysis revealed differences in expression of the A-class <i>APETALA</i> (<i>AP</i>) genes <i>AP1a</i> and <i>AP1b</i> in the double mutant lines. These results suggest that LFY2 plays an important role in floral organ formation in soybean by regulating the expression of homeotic genes.

MHZ3 ensures the interaction of these receptors with CONSTITUTIVE TRIPLE RESPONSE 2 (OsCTR2), thereby maintaining OsCTR2 activity. Ethylene treatment disrupts the interactions within the MHZ3/receptors/OsCTR2 protein complex, leading to decreased OsCTR2 phosphorylation and the initiation of downstream signaling.

There are still many controversial issues in the academic community regarding the origin, migration, and formation process of the Yugur. In this study, we explored the formation process of the Yugur from the perspective of molecular anthropology, based on the paternal genetic characteristics of the Yugur people. And the study will synthesize multiple disciplines, encompassing ethnology, history and linguistics, in order to offer a thorough analysis. Within this research endeavor, a high-resolution kit comprising 35 Y-STRs was employed to examine 237 male specimens from the Yugur people in Gansu province. Y-SNP haplogroups were deduced through the utilization of Y-STR data. The paternal genetic data from diverse populations documented in published literature were merged to construct a 16 Y-STR dataset, a 25 Y-STR dataset, and a dataset detailing haplogroup frequencies. In this study, we employed haplotype network analysis, principal component analysis, multidimensional scaling analysis, phylogenetic tree construction, and genetic distance calculations to delve into the genetic structure, haplotype distribution, and genetic relationship with neighboring populations of the Yugur people. The findings of this study reveal that the Yugur people are a blend of ancestral lineages from both Eastern and Western Eurasian origins, with approximately 13% of their genetic component traced back to Western Eurasian populations. The Yugur people in Gansu province exhibits a more intimate genetic relationship with the Han, Tibetan, and Mongolian populations inhabiting nearby regions, while showing distinct genetic differences with Turkic-speaking groups like the Uyghur.

The availability of Remote Sensing (RS) datasets and Machine Learning (ML) approaches improved the prediction of sugarcane crop yield on the local and global scales, but an additional effort on the plot scale prediction is required. Challenges for plot-level prediction include a high ratooning capacity of the sugarcane crop, the lack of high spatial resolution data during the critical growth stages, and the non-linear complexation of yield data. The principal objective of the study is to analyse the potential of a time series of high-resolution multispectral Unmanned Aerial Vehicle (UAV) imagery along with three advanced ML techniques, namely Random Forest Regression (RFR), Support Vector Regression (SVR), and Nonlinear Autoregressive Exogenous Artificial Neural Network (NARX ANN) as a solution to the plot-level sugarcane yield prediction. An experimental sugarcane field containing 48 plots was selected, and UAV imagery was collected during the three consecutive cropping seasons' early and middle crop growth stages. Each dataset per growth stage was analyzed separately to predict the sugarcane crop yield in an attempt to discover how early the prediction of pre-harvest yield can be achieved. The datasets of the first two cropping seasons were trained and tested using the three ML techniques, utilizing 10-fold cross-validation to avoid overfitting. The third cropping season dataset was then used to evaluate the reliability of the developed prediction models. The results show that the correlation of Vegetation Indices (VIs) with crop yield in the middle stage outperforms the early stage in all three ML models. Moreover, comparing these models indicates that the NARX ANN method outperformed the others in the middle stage with the highest correlation coefficient (R²) of 0.96 and the lowest Root Mean Square Error (RMSE) of 4.92 t/ha. It was followed by the SVR (R² = 0.52, RMSE of 14.85 t/ha), which performed similarly to the RFR method (R² = 0.48, RMSE = 11.20 t/ha). In conclusion, the best-suited model for predicting sugarcane yields during the middle growth stage is a NARX ANN model employing the Normalized Difference RedEdge (NDRE), which demonstrates the feasibility of the ML approaches to predict the plot level sugarcane yield at a specific period of growth as they are less sensitive to the inconsistency of data collection times.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"11 4","pages":"Pages 476-487"},"PeriodicalIF":7.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48925313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
