{"title":"Field evaluation of perennial ryegrass cultivars for use with effluent water irrigation","authors":"Ruying Wang, Conner J. Olsen, Micah A. Gould, Alexander R. Kowalewski","doi":"10.48130/gr-2023-0023","DOIUrl":"https://doi.org/10.48130/gr-2023-0023","url":null,"abstract":"Fresh water is a scarce resource that needs to be conserved. Landscape irrigation, a large portion of the outdoor water use, can be accomplished with water of less-than-potable quality. The use of effluent water generated from residential graywater in landscapes would go a long way toward conserving potable water for other essential uses. The objectives of this study were to evaluate the effect of effluent versus fresh water irrigation on the performance of 11 lawn-height perennial ryegrass (<italic>Lolium perenne</italic> L.) cultivars in the Willamette Valley of Oregon, USA, and determine the effects of effluent water irrigation on soil and tissue analyses. A two-year field trial was established in October 2015 on native soil, and the experimental design was an 11 by 2 strip-plot design with three replications. Synthetic effluent water (water-softening salt, two laundry detergents, and a chelating agent) was applied twice-weekly over perennial ryegrass plots in the summers of 2016 and 2017, and compared to a freshwater control. Small reductions in turf density and color were observed with effluent water irrigation only in June and July of 2017. Our results suggest that effluent water is a viable alternative to freshwater irrigation in the summer of Willamette Valley, where there is little to no precipitation. However, the accumulation of Na, Cl, and B in the soil and plant tissue indicates that future research is warranted to determine any long-term effects from effluent water irrigation on turfgrass and soil health.","PeriodicalId":197485,"journal":{"name":"Grass Research","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135560516","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}

{"title":"Spectral Reflectance Estimated Genetic Variation in Hybrid Turf Bermudagrass","authors":"Desalegn D. Serba, Yanqi Wu, Reagan Hejl, Clinton Williams, Kevin Bronson","doi":"10.48130/gr-2023-0022","DOIUrl":"https://doi.org/10.48130/gr-2023-0022","url":null,"abstract":"High throughput phenotyping (HTP) utilizing both remote and proximal sensing technologies has emerged as a vital tool for evaluating the biophysical characteristics of turfgrass. This study was conducted to assess the genetic diversity of hybrid turf bermudagrass using spectral reflectance indices and use of HTP for germplasm enhancement. A total of 50 accessions of the hybrid bermudagrass (<italic>Cynodon dactylon</italic> × <italic>C. transvaalensis</italic>) were grown in the greenhouse in three replications. The spectral data were gathered using a height independent active crop canopy sensor, 'RapidScan CS-45', which measures canopy reflectance at the wavelengths of 670 nm, 730 nm, and 780 nm. The reflectance data were used to derive three indices related to canopy photosynthetic area and other three related to chlorophyll content. All vegetation indices showed significant genotype-to-genotype variation. Ten superior genotypes were identified using the multi-trait genotype-ideotype distance index (MGIDI) as a selection differential. On 48 of the genotypes that were established in the field in two replications, establishment rate and winter color data were also gathered. The results of a linear regression analysis demonstrated the importance of spectral vegetation indices (SVI) for the turfgrass quick establishment (percentage area coverage) and winter color retention. This study brings attention to the potential use of the proximal sensing in turfgrass germplasm enhancement for establishment speed, aesthetic value, and mild-winter color retention.","PeriodicalId":197485,"journal":{"name":"Grass Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135505582","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}

Unlike animals, dioecious angiosperms account for only about 6% of the total. Buffalograss (<italic>Buchloe dactyloides</italic>) plays a vital role in environmental restoration, creating economic benefits and promoting the high-quality development of the grassland and turf industries. Its natural populations contain differing ratios of male, female, and monoecious plants. The value of buffalograss for studying the sex differentiation mechanism in plants cannot be ignored. However, few studies have investigated transcript annotation and complete mRNA structure in <italic>B. dactyloides</italic>, and the pathways of species-specific factors in sex differentiation remain unknown. We integrated the full-length transcriptome, second-generation transcriptome, and metabolome to specify candidate factors influencing sex differentiation. We identified 110,870 full-length transcripts and obtained 100,362 (90.52%) transcript and annotation information. Then we identified 49,448 differentially expressed genes (DEGs) and 3,070 differentially accumulated metabolites (DAMs) in female, male, and monoecious leaf samples. The co-enrichment analysis indicated that sexual differentiation was regulated by glutathione metabolism, photosynthesis, plant hormone biosynthesis, catabolism, and signaling. The identification of DEGs and DAMs that participate in glutathione metabolism, photosynthesis, abscisic acid (ABA), cytokinin (CTK), and gibberellin (GA) biosynthesis, catabolism, and signaling has helped illuminate the roles of plant hormones in the sex differentiation of <italic>B. dactyloides</italic>. The full-length transcriptomic data will facilitate additional studies on functional genes. Integration of transcriptomic and metabolomic data advances knowledge of the molecular mechanism of sex differentiation and provides information for <italic>B. dactyloides</italic> breeding programs.","PeriodicalId":197485,"journal":{"name":"Grass Research","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135560297","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}

Alfalfa (<italic>Medicago sativa</italic> L.) is a perennial forage crop planted worldwide that has a well-developed root system and salt tolerance. Cytochrome P450 monooxygenase (CYP450) genes play important roles in flavonoid synthesis, plant growth, and development. However, few studies have focused on CYP450s in forage grass, especially the role of CYP450 genes in plant resistance to environmental stresses, such as drought and high salinity. In this study, 376 menbers in MsCYP family genes were identified using hmmsearch and BLASTP in the alfalfa protein database using the AtCYP450 protein sequence. Then by exploring MsCYP gene structures, tandem and segmental duplication events, and evolutionary relationships with CYP450s in other plants, potential MsCYPs that respond to salt stress were screened. Candidate genes were selected for transient expression in tobacco and heterologous overexpression in <italic>Arabidopsis</italic> for salinity response. This study provides a foundation for verifying the function of MsCYPs in improving the quality of agricultural products.","PeriodicalId":197485,"journal":{"name":"Grass Research","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135104561","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}
