The fungus, herein named <em>Desertella arida</em> Stanghellini &amp; Mohammadi sp. nov., was associated with roots of diverse plants including brassica (Sahara mustard (<em>Brassica tournefortii</em>), shepherd's purse (<em>Capsella bursa</em>-<em>pastoris</em>)) and plantain (<em>Plantago ovata</em> Forsk). The fungus forms extensive multinucleate, septate hyphae (6–17 μm in diameter) bearing hundreds of large spherical to pear-shaped unicellular asexual spores (50–120 μm in diameter), either singly or in large clusters. The spores are beige to cream-colored, thin-walled, and contain a dense, granular cytoplasm. Further investigation on the distribution of <em>D. arida</em> in soils of desert habitats in the southwestern USA led to the discovery of a second fungus belonging to a different species herein named <em>Desertella americanense</em> Mohammadi &amp; Stanghellini sp. nov.<em>,</em> in California, Arizona, Nevada, and Utah. The two species are morphologically similar. Spores from both fungi in native soil survived heat treatment up to 100 °C. Both species are culturable and colonized roots of monocots and dicots forming abundant hyphae and spores as early as 10 days post-inoculation. <em>Desertella arida</em> significantly enhanced shoot growth in broccoli, lettuce, <em>Plantago ovata</em> and flax. In conclusion, we discovered two desert-dwelling ascomycete fungi that were associated with the roots of native plant species in southern California. They were culturable on a synthetic medium, heat-tolerant and promoted growth on several crop species. These fungi appeared to exist in other neighboring states such as Arizona and Nevada.</p></div>","PeriodicalId":37938,"journal":{"name":"Ecological Genetics and Genomics","volume":"32 ","pages":"Article 100265"},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405985424000491/pdfft?md5=ddca020cf8030d48fe75e77e41a9d3bf&pid=1-s2.0-S2405985424000491-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141095083","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}

Furthermore, a multi-environment trial assessed 41 hybrids across 4 research stations in 2 winter seasons using RCB design. Likewise, compiled cutting-edge statistical methods for GEI analyses from the “metan” package (R-Software), selected hybrids with consistent performance with meticulous analysis. AMMI(Additive Main effects and Multiplicative Interaction)analysis revealed that of significant (p ≤ 0.05) effects of genotype, environment, &amp; genotype-environment interaction (GEI), explaining yield variance with interaction effects were captured by 3 interaction principal components (IPCs). Moreover,GEI graphics of AMMI biplots elucidates four hybrids(MRM-4062, Super-22, PAC-744, and Gen-4118) with high yield stability and above-average performance. Additionally, eight hybrids (4118, 4558, 5454, NMH1258, PAC 746, PAC 745 Gold, and SUPER 9090) exhibited superior yield, regardless of their stability. Nepalgunj exhibited the lowest GEI value.

Besides this, GGE biplot revealed two potential mega-environments based on yield similarities. Nine high-yielding hybrids (SUPPER 6768, SUPPER 9396, PAC750, MBS5622, PAC745 Gold, MRM4065, NMH8392, Gen-4118, and Gen-4558) were identified as vertex hybrids, signifying their superior performance across wide environments.

Understanding the genetic diversity of <em>M. pruriens</em> is vital for its conservation and utilization in breeding programs aimed at enhancing its nutritional and agronomic traits. In this regard, molecular markers like ISSRs offer a reliable and informative tool for assessing genetic diversity. In the present study, 23 <em>M. pruriens</em> accessions from northeastern India were evaluated using ISSR markers, revealing high levels of polymorphism and significant genetic diversity. A total of 512 amplicons were generated across 33 ISSR primers, with an average polymorphic percentage of 98.05 %. PIC values ranged from 0.22 to 0.50, indicating substantial genetic variation within the accessions. Supplementary indicators such as EMR and MI were employed to evaluate the marker system's efficacy. EMR ranged from 6 to 22, averaging 14.95, while MI ranged from 2.64 to 9.02, averaging 6.04, with a positive correlation observed between EMR and MI.

The field of genomics is conceived as the scientific study of a species' genome's structure and function using several nucleotide sequences. Genomic selection is the selection of a population based on estimated genomic breeding values. It has been applied as an invaluable tool for increasing the rate of genetic gain with reduced generation intervals while maintaining a good level of selection accuracy. Moreover, it has been widely used for the selection of superior animals with great accuracy at an early age, resulting in enhanced productivity in dairy cattle populations. Genomic selection is particularly efficient in improving low-heritability traits related to the efficiency of feed conversion, reproduction, adaptation to changing production environments, and resistance to various disease transmitting pathogens and vectors. Genomic selection implementation requires careful model selection, and one of the popular models is best linear unbiased prediction (BLUP). Most studies have shown that pure breeds' genomic evaluation can be utilized to improve productivity, efficiency, and genetics by providing a large reference population for dairy cows with high milk production.
