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 …

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.
