Its control remains challenging mainly due to its rapid reproduction, necessitating an understanding of sex pheromone communication. The recognition of sex pheromones is vital for courtship and mating behaviors, and is mediated by various chemosensory-associated proteins. Among these, sensory neuron membrane protein (SNMP), a CD36-related protein, is suggested to play crucial roles in detecting sex pheromones. In this study, we employed transcriptomic and genomic data from . and phylogenetic approaches, and identified four putative genes (, and ) with full open reading frames. Expression analysis revealed the ubiquitous presence of transcripts in multiple tissues, with only exhibiting male-biased expression in the antennae, suggesting its potential role in male chemosensation. Functional analysis using the oocyte expression system, coupled with two-electrode voltage clamp recording, demonstrated that the co-expression of AlucSNMP1a with specific pheromone receptors (PRs) and the co-receptor (Orco) significantly enhanced electrophysiological responses to sex pheromones compared to the co-expression of PRs and Orco alone. Moreover, the results indicated that the presence of AlucSNMP1a not only affected the responsiveness to sex pheromones but also influenced the kinetics (activation and inactivation) of the induced signals. In contrast, the co-expression of AlucSNMP1b with AlucPR/Orco complexes had no impact on the inward currents induced by two pheromone compounds. An examination of the selective pressures on genes across 20 species indicated strong purifying selection, implying potential functional conservation in various insects. These findings highlight the crucial role of AlucSNMP1a in the response to sex pheromones.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"14 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing unmanned aerial vehicle (UAV) remote sensing, this study explored the applicability of an empirical crop water stress index (CWSI) based on canopy temperature and three-dimensional drought indices (TDDI) constructed from surface temperature (), air temperature () and five vegetation indices (VIs) for monitoring the moisture status of dryland crops. Three machine learning algorithms (random forest regression [RFR], support vector regression, and partial least squares regression) were used to compare the performance of the drought indices for vegetation moisture content (VMC) estimation in sorghum and maize. The main results of the study were as follows: (1) Comparative analysis of the drought indices revealed that --Normalized Difference Vegetation Index (TDDIn) and --Enhanced Vegetation Index (TDDIe) were more strongly correlated with VMC compared with the other indices. The indices exhibited varying sensitivities to VMC under different irrigation regimes; the strongest correlation observed was for the TDDIe index with maize under the fully irrigated treatment (=−0.93); (2) Regarding spatial and temporal characteristics, the TDDIn, TDDIe and CWSI indices showed minimal differences over the experimental period, with coefficients of variation were 0.25, 0.18 and 0.24, respectively. All three indices were capable of effectively characterizing the moisture distribution in dryland maize and sorghum crops, but the TDDI indices more accurately monitored the spatial distribution of crop moisture after a rainfall or irrigation event. (3) For prediction of the moisture content of single crops, RFR models based on TDDIn and TDDIe estimated VMC most accurately (0.7), and the TDDIn-based model predicted VMC with the highest accuracy when considering multiple-crop samples, with and RMSE of 0.62 and 14.26%, respectively.

Also, modulating source-sink relationships through crop management has been used to improve crop productivity. This study aims to investigate whether and how modifying leaf colour alters source-sink relationships and whether current crop cultivation practices remain applicable for leaf-colour modified genotypes. Periodically collected data of total biomass and nitrogen (N) accumulation in rice genotypes of four genetic backgrounds and their leaf-colour modified (greener or yellower) variants were analysed, using a recently established model method to quantify the source-sink (im)balance during grain filling. Among all leaf-colour variants, only one yellower-leaf variant showed higher source capacity than its normal genotype. This was associated with increased post-flowering N-uptake that prolonged functional leaf-N duration, and this increased post-flowering N-uptake was possible because of reduced pre-flowering N-uptake. The density experiment showed that current management practices (insufficient planting density accompanied with abundant N application) were unsuitable for the yellower-leaf genotype, ultimately limiting its yield potential. Leaf-colour modification affects source-sink relationships by regulating N trade-off between pre-flowering and post-flowering uptake, and N translocation between source and sink organs. To best exploit leaf-colour modification for an improved crop productivity, adjustments of crop management practices are required.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"86 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140070004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlation analysis between six root morphological traits revealed a strong positive correlation of TRL with RSA, RV with RSA and AvgD, whereas a significant negative correlation between TRL and AvgD. Subsequently, a genome-wide association study (GWAS) was performed using the root phenotypic data and genotypic data reported previously for 242 accessions using 56,010 single nucleotide polymorphisms (SNPs) from the CottonSNP80K array. A total of 41 quantitative trait loci (QTLs) were identified with 9 for MRL, 6 for RFW, 9 for TRL, 12 for RSA, 12 for RV and 2 for AvgD respectively. Among them, 8 QTLs were repeatedly detected in two or more traits. Integrated with transcriptome analysis, we identified 17 candidate genes with high transcripts of transcripts per million (TPM)≥30 in roots. Furthermore, we verified functionally a candidate gene encoding a WPP domain protein 2 in root development.

However, it can also exacerbate problems such as wheat floret degeneration, leading to reduced yields. Therefore, investigating wheat floret degeneration mechanisms under low nitrogen stress and identifying mitigation measures are conducive to achieving high yields and sustainable development. To investigate the physiological mechanism of low nitrogen stress affecting wheat floret degradation and whether exogenous brassinosteroids can alleviate this stress, three nitrogen application rates (N0, no nitrogen application; N1, 120 kg ha pure nitrogen; and N2, 240 kg ha pure nitrogen) and exogenous spraying experiments (N0CK, no nitrogen with water spraying; N0BR, no nitrogen with 24-epibrassinolide (an active brassinosteroids) spraying; and N1, 120 kg ha pure nitrogen with water spraying) were designed. The results indicated that low nitrogen stress induced a large amount of reactive oxygen species generation. Although wheat spikes synthesized flavonoids to combat oxidative stress, their energy metabolism (glycolysis and tricarboxylic acid cycle) and ascorbate-glutathione cycle were inhibited, keeping reactive oxygen levels elevated within the spike, inducing cell death and exacerbating floret degeneration. Furthermore, brassinosteroids played a role in regulating wheat floret degeneration under low-nitrogen stress. Exogenous foliar spraying of 24-epibrassinolide promoted energy metabolism and the ascorbate-glutathione cycle within the spike, enhancing energy charge and effectively mitigating a portion of reactive oxygen induced by low nitrogen stress, thereby alleviating floret degeneration caused by low nitrogen stress. In summary, low-nitrogen stress disrupts the redox homeostasis of wheat spikes, leading to floret degeneration. Brassinosteroids alleviate floret degeneration by improving the redox state of wheat spikes. This research provides theoretical support for balancing the contradiction between high yields and sustainable development and is beneficial for the application of low nitrogen in production.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"294 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140070172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we demonstrated that the overexpression of is associated with a decrease in PME activity and an increase in pectin methylesterification. This leads to the softening of the cell wall in seeds, which positively regulates cotton seed germination. AtPMEI19, the homologue in , plays a similar role in seed germination to GhPMEI53, indicating a conserved function and mechanism of PMEI in seed germination regulation. Further studies revealed that GhPMEI53 and AtPMEI19 directly contribute to promoting radicle protrusion and seed germination by inducing cell wall softening and reducing mechanical strength. Additionally, the pathways of ABA and GA in the transgenic materials underwent significant changes, suggesting that GhPMEI53/AtPMEI19-mediated pectin methylesterification serves as a regulatory signal for the related phytohormones involved in seed germination. In summary, GhPMEI53 and its homologs alter the mechanical properties of cell walls, influencing the mechanical resistance of the endosperm or testa. Moreover, they impact cellular phytohormone pathways (e.g., ABA, GA) to regulate seed germination.

However, the application of this approach is impeded by the diverse ecological types of soybeans, their adaptability to the introduction, and the uncertainty surrounding the growth phenotype post-introduction. In this study, 24 grain soybean varieties from low-latitude regions (22-31°N) were introduced to the high-latitude northwestern Loess Plateau (39°N) between 2018 and 2019. The growth phenotypes were observed, and their forage productivity potential was assessed. All varieties displayed delayed flowering following cross-latitude introduction, with the vegetative growth phase of some varieties even exceeding their entire growth duration at their origin. Rapid dry matter accumulation rates were indicative of growth adaptation performance and formed the basis for soybean forage yield. Varieties from the tropical south China region exhibited significant yield advantages, with dry matter yields of 8.97-14.68 t ha and crude protein yields of 1.44-2.51 t ha. Varieties HX3 and GX7, originating from this region, demonstrated optimal growth adaptability and productivity in the cross-latitude environment, achieving the highest dry matter yields of 14.68 and 13.86 t ha, respectively. As a result, HX3 and GX7 are recommended for local farming systems to provide high-quality forage. The cross-latitude introduction of soybean is proposed as a viable and efficient strategy for forage improvement and application.","PeriodicalId":16305,"journal":{"name":"Journal of Integrative Agriculture","volume":"96 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140070090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
