Full-length transcriptome and co-expression network analysis reveal molecular mechanisms of seed development in Elymus sibiricus Seed Sci. Res. (IF 2.1) Pub Date : 2024-05-16 Yuying Zheng, Xiaoshan Lin, Wengang Xie, Wenxian Liu
Grass seeds play a critical and fundamental role in grass breeding and production. Elymus sibiricus L. is a widespread Poaceae forage grass in northern Eurasia which is used for ecological restoration and forage production. Sucrose is the main source of substrate and energy required for starch synthesis in the seeds, so the hydrolysis of sucrose determines and influences starch synthesis and filling

Accuracy of genomic prediction using multiple Atlantic salmon populations Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-05-15 Afees A. Ajasa, Solomon A. Boison, Hans M. Gjøen, Marie Lillehammer
The accuracy of genomic prediction is partly determined by the size of the reference population. In Atlantic salmon breeding programs, four parallel populations often exist, thus offering the opportunity to increase the size of the reference set by combining these populations. By allowing a reduction in the number of records per population, multi-population prediction can potentially reduce cost and

QTL mapping reveals malt barley quality improvement in two dryland environments associated with extended grain fill and seminal root traits Crop Sci. (IF 2.3) Pub Date : 2024-05-15 Jessica L. Williams, Peggy F. Lamb, Greg Lutgen, Jennifer Lachowiec, Jason P. Cook, Joseph Jensen, Maryse Bourgault, Jamie D. Sherman
To achieve malt grade and receive full price, barley (Hordeum vulgare L.) crops must meet standards for certain quality traits including percent plump and protein. Terminal drought stress reduces quality and is projected to worsen in barley cultivation areas, underscoring the need for varieties that maintain good malt production with unreliable precipitation.

Recursive models are a category of structural equation models that propose a causal relationship between traits. These models are more parameterized than multiple trait models, and they require imposing restrictions on the parameter space to ensure statistical identification. Nevertheless, in certain situations, the likelihood of recursive models and multiple trait models are equivalent. Consequently

The germination percentage (GP) is commonly employed to estimate the viability of a seed population. Statistical methods such as analysis of variance (ANOVA) and logistic regression are frequently used to analyse GP data. While ANOVA has a long history of usage, logistic regression is considered more suitable for GP data due to its binomial nature. However, both methods have inherent issues that require

Characterization of Paspalum genotypes for turfgrass cultivars development Crop Sci. (IF 2.3) Pub Date : 2024-04-01 Frederico de Pina Matta, Alessandra Pereira Fávero, Bianca Baccili Zanotto Vigna, Marcelo Mattos Cavallari, Fábio Alves, Fernanda Ancelmo de Oliveira, Anete Pereira de Souza, Marisa Toniolo Pozzobon, Ana Luisa Sousa Azevedo, Marcos Rafael Gusmão
The characterization of genetic resources is essential to carry out a breeding program. This study aimed to characterize Paspalum genotypes with potential use as soil surface covering to support breeding programs on the development of turf cultivars. Forty‐three Paspalum genotypes, comprising 11 species, were evaluated. The embryo‐sacs structure was determined by cleared ovaries analysis and eight

Persistence and relocation of dislodgable herbicide residue from simulated rainfall following glyphosate treatment to dormant zoysiagrass turf Crop Sci. (IF 2.3) Pub Date : 2024-04-01 Navdeep Godara, Jordan M. Craft, Clebson G. Gonçalves, Shawn D. Askew
The severity of herbicide injury to dormant zoysiagrass (Zoysia spp.) increases with increasing green leaves at treatment time, but injury also occurs following treatment to fully dormant zoysiagrass, especially when treatment precedes rapid shoot emergence. Research was conducted to determine the persistence of radio‐labeled glyphosate or glufosinate on dormant zoysiagrass leaves, to assess how simulated

Genomic prediction of sweet sorghum agronomic performance under drought and irrigated environments in Haiti Crop Sci. (IF 2.3) Pub Date : 2024-04-01 Jean Rigaud Charles, Marie Darline Dorval, Jean Bernard Durone, Luis Felipe Ventorim Ferrão, Rodrigo Rampazo Amadeu, Patricio Ricardo Munoz, Geoffrey Morris, Geoffrey Meru, Gael Pressoir
Over the past decade, genomic selection (GS) has gained significant traction as a valuable tool for predicting the phenotypic performance in plant breeding populations and for expediting the development of new cultivars. Diverse statistical models and approaches have been developed to facilitate the integration of GS into plant breeding practices, with a growing emphasis on strategies that enhance

In-silico analysis and transformation of OsMYB48 transcription factor driven by CaMV35S promoter in model plant – Nicotiana tabacum L. conferring abiotic stress tolerance GM Crops Food (IF 3.9) Pub Date : 2024-03-29 Yumna Ahmad, Saqlain Haider, Javed Iqbal, Sana Naseer, Kotb A. Attia, Arif Ahmed Mohammed, Sajid Fiaz, Tariq Mahmood
Global crop yield has been affected by a number of abiotic stresses. Heat, salinity, and drought stress are at the top of the list as serious environmental growth-limiting factors. To enhance crop ...

Effect of temperature-humidity index on the evolution of trade-offs between fertility and production in dairy cattle Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-03-29 Aurélie Vinet, Sophie Mattalia, Roxane Vallée, Christine Bertrand, Anne Barbat, Julie Promp, Beatriz C. D. Cuyabano, Didier Boichard
In the current context of climate change, livestock production faces many challenges to improve the sustainability of systems. Dairy farming, in particular, must find ways to select animals that will be able to achieve sufficient overall production while maintaining their reproductive ability in environments with increasing temperatures. With future forecasted climate conditions in mind, this study

A common regulatory haplotype doubles lactoferrin concentration in milk Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-03-28 Thomas J. Lopdell, Alexander J. Trevarton, Janelle Moody, Claire Prowse-Wilkins, Sarah Knowles, Kathryn Tiplady, Amanda J. Chamberlain, Michael E. Goddard, Richard J. Spelman, Klaus Lehnert, Russell G. Snell, Stephen R. Davis, Mathew D. Littlejohn
Bovine lactoferrin (Lf) is an iron absorbing whey protein with antibacterial, antiviral, and antifungal activity. Lactoferrin is economically valuable and has an extremely variable concentration in milk, partly driven by environmental influences such as milking frequency, involution, or mastitis. A significant genetic influence has also been previously observed to regulate lactoferrin content in milk

Assessment of bioactive compounds, antioxidant potential, and enzymatic activity in different guava (Psidium guajava) cultivars Crop Sci. (IF 2.3) Pub Date : 2024-03-26 Priyanka Kumari, Abhay Mankar, Kumari Karuna, Fozia Homa, Riadh Ilahy, Mohammed Wasim Siddiqui
Fresh fruits of five guava (Psidium guajava L.) cultivars were assessed for ascorbic acid (AA) content and enzymatic antioxidants (superoxide dismutase [SOD] and ascorbate peroxidase [APX]) activities, while extracted peel and pulp samples were analyzed for total phenol (TP) and total flavonoids (TFs). The hydrophilic and lipophilic antioxidant activity was evaluated using six different analytical
