Soybean [Glycine max(L.) Merr.] is a globally important crop due to its valuable seed composition, versatile feed, food, and industrial end-uses, and consistent genetic gain. Successful genetic gain in soybean has led to widespread adaptation and increased value for producers, processors, and consumers. Specific focus on the nutritional quality of soybean seed composition for food and feed has further elucidated genetic knowledge and bolstered breeding progress. Seed components are historical and current targets for soybean breeders seeking to improve nutritional quality of soybean. This article reviews genetic and genomic foundations for improvement of nutritionally important traits, such as protein and …

Effect Of Plant Genotype On Plant-Microbe Interactions And Multi-Generation Ecosystem Selection Of Microbial Communities Associated With Plant Biomass In Arabidopsis Thaliana, Nachiket Shankar

Graduate Doctoral Dissertations

The microbiome's role in shaping host phenotypes is a critical area of investigation, with implications for ecology, evolution, and host health. Dynamic plant-microbe interactions are influenced by factors like soil type, environment, and genotype. Understanding their impact on microbial communities is key for tailored plant benefits. An artificial ecosystem selection experiment was done for eight generations with Arabidopsis thaliana Ler and Cvi. This revealed distinct microbial communities shaped by genotypes and biomass treatments. Initially, environment dominated, but over time, genotype and biomass gained influence, explaining ~40% of the variation. Moreover, genotype-specific rhizobacterial associations were observed, enhancing understanding of community dynamics …

Genetic Diversity: The Hub Of Plant Breeding, Foster Kangben

English Language Institute

Agriculture the world over is faced with the threat of food, fiber, and nutrition insecurity especially in the wake of climate change. However, employing two approaches to plant breeding, the molecular and phenotypic methods, can make use of genetic diversity in crop species in order to help surmount these challenges.

Increasing Expression Of Hepatitis B Surface Antigen In Maize Through Breeding, Erin Suzanne Miller

Master's Theses

The hepatitis B virus (HBV) is a common virus, with two billion people infected worldwide. It causes approximately 600,000 deaths each year, despite the availability of an effective vaccine since 1982. Maize as a platform for oral vaccination can supply a heat stable vaccine, which does not require syringes or trained personnel to administer. The Hepatitis B Surface antigen was transformed into maize and this seed was used to evaluate expression levels through the breeding process. The transgene was transferred into two elite maize inbreds by backcrossing. Highest expressing ears were selected each generation until approximately 99% commercial parent was …

Biotechnology : Exposing The Myths & Realities, Sue Sutherland, Alan Lymbery

Journal of the Department of Agriculture, Western Australia, Series 4

Biotechnology has become one of the buzz words of the 1990s. Sounds impressive but what's it all about? Sue Sutherland and Alan Lymbery unravel some of the jargon and explore its potential for Western Australian agriculture.

Breeding Better Malting Barleys, Ross Gilmour, Allen Tarr, Stefan Harasymow

Journal of the Department of Agriculture, Western Australia, Series 4

Development of new barley cultivars in Western Australia has substantially improved the grain yield and quality of the State's barley crop. This has increased returns to barley growers and enhanced Western Australia's reputation in export markets as a major supplier of barley for malting and feed.

The State exports more than 200, 000 t of malting barley, 60, 000 t of barley malt and 150, 000 t of feed barley each year.

The major challenge for the future is to develop new, high yielding cultivars with improved malting quality.

In this article, the authors discuss the achievements of the past; …

Breeding Field Peas In Western Australia, T N. Khan

Journal of the Department of Agriculture, Western Australia, Series 4

Field peas have grown dramatically in popularity in western Australia in the past five years, with the planted area increasing from a mere few hundred hectares to about 70,000 ha in 1988. This growth may continue, as more than 700,000 ha of agricultural land is potentially suitable for growing field peas.

However, any such growth of the pea industry will require new cultivars with improved yield, adaptation and quality characteristics to meet local and export demands. The Department of agriculture therefore decided to start a selection and breeding programme to support the pea industry.
