Barley is reportedly the world\u2019s fourth most important cereal crop, and the IPSR Center maintains a large barley collection from all over the world. Our main interests include genes that control seed \/ flower morphology and quality-related characteristics. For example, typical barley cultivars have caryopsis with adhering hulls at maturity, known as covered (hulled) barley. However, some barley cultivars are of a freethreshing variant, called naked (hulless) barley. Covered barley is used as an animal feed and for brewing, although naked barley is well suited for use as human food. We identified the gene controlling covered\/naked caryopsis trait in barley through positional cloning. We revealed that an ethylene response factor (ERF) family transcription factor engenders this trait. Functional analyses of Nud\/nud gene at the molecular levels are currently underway in the laboratory. Furthermore, we have identified polyphenol oxidase genes, 1;3, 1;4 beta-glucan synthesis genes and genes determining awn length (Lks2).\n<p style=\"text-align: left;\"><span style=\"color: #339966;\">Professor\uff1aShin Taketa<\/span><\/p>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.rib.okayama-u.ac.jp\/wp-content\/uploads\/2012\/06\/hccc11.png\" alt=\"\" \/><br \/>\n<strong><a href=\"https:\/\/www.rib.okayama-u.ac.jp\/english\/research\/ng-hp\/\" rel=\"noopener noreferrer\">Group of Integrated Genomic Breeding<\/a><\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.rib.okayama-u.ac.jp\/english\/research\/ng-hp\/\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" id=\"hidari\" class=\"alignnone\" src=\"https:\/\/www.rib.okayama-u.ac.jp\/wp-content\/uploads\/2012\/05\/saiboubunretsu.png\" alt=\"\" width=\"190\" height=\"240\" align=\"left\" \/><\/a><\/li>\n<li id=\"group3\" style=\"text-align: justify;\">Nuclei which have very complex structures and various functions are the most important organelle in eukaryotic cells. Nuclear DNA is divided and packed into chromosomes, enabling accurate transmission of genetic information to daughter cells. Our research group is studying the molecular structures and functions of nuclei and chromosomes, mainly in plants. Our most recent goal is development of artificial plant chromosomes by analyzing chromosome functional elements: centromeres, telomeres, and replication origins.
