It has been argued that the evolution of plant genome size is principally unidirectional and increasing owing to the varied action of whole-genome duplications (WGDs) and mobile element proliferation. Although the genetic architecture of these traits has been dissected using different populations, the genetic basis remains unclear in the F1 population. Chromatin compartmentalization might be driven through liquidâliquid phase-separation mechanisms. Unraveling the 3D Genome Architecture in Plants: Present and Future Weizhi Ouyang 1 ,3, Dan Xiong , Guoliang Li 2 * and Xingwang Li1,* 1National Key Laboratory of Crop Genetic Improvement, Huazhong Agricultural University, Wuhan 430070, China 2Hubei Key Laboratory of Agricultural Bioinformatics and Hubei Engineering Technology Research Center of Agricultural Big Data, 3D Genomics Research â¦ Population genomic data enable us to understand the mechanisms and the history of changes in genome â¦ Epub 2013 May 12. Here, we highlight three important emergent realizations: (1) that the evolutionary history The Plant Genome is a gold open access journal that provides the latest advances and breakthroughs in plant genomics research, with special attention to innovative genomic applications that advance our understanding of plant biology that may have applications to crop improvement.

Architecture and evolution of a minute plant genome. However, extreme genome size reductions have been reported in the angiosperm family tree. The fungal kingdom comprises some of the most devastating plant pathogens. 1. 2016 Mar 1;17:37. doi: 10.1186/s13059-016-0908-1. 10 A; Hallé et al., 1978 ; Barthélémy et al., 1989 , 1991) whereas the axes it gives rise to are referred to order 2 axes and so on. The plant genome is packaged into the nucleus, forming a hierarchical three-dimensional (3D) structure with extensive DNAâDNA and DNAâRNA interactions, which provides a topological basis for transcriptional regulation. Wendel JF(1), Jackson SA(2), Meyers BC(3)(4), Wing RA(5)(6). 1. Genome Biol. 2013 Jun 6;498(7452):94-8. doi: 10.1038/nature12132. Plant architecture, including plant height, leaf angle, leaf length, and leaf width, has been changed significantly to adapt to higher planting density. Sequencing the genomes of fungal pathogens has shown a remarkable variability in genome size and architecture. In plant architecture analysis it is usual to use ordinal numbers and to consider the main stem arising from seed as the order 1 axis (Fig. Brassica juncea (AABB), commonly referred to as mustard, is a natural allopolyploid of two diploid species â B. rapa (AA) and B. nigra (BB). Evolution of plant genome architecture Jonathan F. Wendel1*, Scott A. Jackson2, Blake C. Meyers3,4 and Rod A. Wing5,6 Abstract We have witnessed an explosion in our understanding of the evolution and structure of plant genomes in recent years. We found that these plant genomes can be divided into mammalian-like A/B compartments. Evolution of plant genome architecture. Genome-wide association studies and whole-genome prediction reveal the genetic architecture of KRN in maize Yixin Anâ , Lin Chenâ , Yong-Xiang Li, Chunhui Li, Yunsu Shi, Dengfeng Zhang, Yu Li* and Tianyu Wang* Abstract Background: Kernel row number (KRN) is an important trait for the domestication and improvement of maize. Here, we investigated the genetic architecture underlying plant responses to 11 single stresses and several of their combinations by phenotyping 350 Arabidopsis thaliana accessions. In this study, we examine the chromatin architecture, as well as their DNA methylation, histone modifications, accessible chromatin, and gene expression, of maize, tomato, sorghum, foxtail millet, and rice with genome sizes ranging from 0.4 to 2.4 Gb. Here we report the sequence of the 82-megabase genome of the carnivorous bladderwort plant Utricularia gibba.
