This book was released on 2024-01-26 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genome-wide association studies (GWAS) have been widely used in the genetic dissection of complex traits. However, there are still limits in current GWAS statistics. For example, (1) almost all the existing methods do not estimate additive and dominance effects in quantitative trait nucleotide (QTN) detection; (2) the methods for detecting QTN-by-environment interaction (QEI) are not straightforward and do not estimate additive and dominance effects as well as additive-by-environment and dominance-by-environment interaction effects, leading to unreliable results; and (3) no or too simple polygenic background controls have been employed in QTN-by-QTN interaction (QQI) detection. As a result, few studies of QEI and QQI for complex traits have been reported based on multiple-environment experiments. Recently, new statistical tools, including 3VmrMLM, have been developed to address these needs in GWAS. In 3VmrMLM, all the trait-associated effects, including QTN, QEI and QQI related effects, are compressed into a single effect-related vector, while all the polygenic backgrounds are compressed into a single polygenic effect matrix. These compressed parameters can be accurately and efficiently estimated through a unified mixed model analysis. To further validate these new GWAS methods, particularly 3VmrMLM, they should be rigorously tested in real data of various plants and a wide range of other species.

This book was released on 2018 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: As sessile organisms, plants are exposed to numerous environmental stresses during their lifetimes. These include challenges related to drought, salinity, and low nutrient availability, all of which can negatively impact plant growth and development and reduce crop yields. Currently, drought and nutrient limitation are offset through increased irrigation and fertilizer application, however, these agricultural inputs are environmentally, economically, and energetically costly. Moreover, irrigation can lead to soil salinization. Attention has thus turned to the development of increasingly resilient crops, but such efforts require knowledge of the mechanistic basis of variation in growth and performance under stress. Here, I describe research aimed at characterizing genetic variation underlying seedling growth traits in cultivated sunflower (Helianthus annuus L.) under well-watered and water-limited (i.e., osmotic stress), as well as the phenotypic and transcriptomic response of such seedlings to multiple water-related stresses as well as nutrient limitation. Genome-wide association studies revealed that cultivated sunflower harbors substantial variation for seedling growth and root-related traits under both well-watered and water-limited conditions, with evidence that many of the significantly associated regions had consistent effects across environments. Moreover, the transcriptomic response to water-related stresses (drought, osmotic, and salt), revealed that over 30% (502/1332) of differentially expressed genes (DEGs) were shared between at least two stresses, with 51 DEGs shared across all three stresses, in either leaf or root tissue. There was an overall bias toward up-regulation of DEGs, particularly in roots, and there were substantially more DEGs in roots vs. leaves. All 51 of the DEGs shared across these three stresses exhibited a common direction of response, and this pattern held for the subset of 26 DEGs that were also shared with low nutrient stress. Under nutrient stress, however, there were substantially more DEGs in leaves vs. roots, though there was a similar bias toward up-regulation. Taken together, these results add to a growing body of data on the genetic basis of phenotypic variation under stress, as well as the phenotypic and transcriptomic response of plants to a variety of abiotic stresses.

Book excerpt: This book presents a broad number of recent discoveries, advances and important results concerning sunflower (Helianthus annus) crops and its related fields, with emphasis on the detailed study of several diseases and pests that can affect sunflowers (production, water resources needed, economy impact) in different regions of the globe, including Russia, both North and South America, Africa, India and Europe. We are all well aware of the increasing importance, as well as the economic impact that these plants have reached in recent years, not only in the food industry but also in the western energy market, with the increasing use of sunflower oil as a natural energy resource for biodiesel and biofuel. Apart from the interesting recent advances, results and conclusions presented in every chapter, plenty of visual and graphical content comprised of tables, charts, graphs, pictures and high quality detailed photographs and images showing different issues and problems regarding sunflower crops are also included. The manuscript chapters have been authored by experts in the field and in addition all of them underwent a stringent peer review process by expert reviewers to assure a high final scientific quality.
