The Institute of Vegetable and Floriculture Science, NARO (NIVFS) conducts basic and innovative research to support the breeding and cultivation of vegetables and ornamental plants, reduction of environmental impact, and development of technologies for sustainable production, improvement of quality, and efficient distribution etc.
Alteration of traits in chrysanthemum by genome editing
Press release on 10 Mar 2017
Mutations in chrysanthemum have been successfully introduced by gene editing technology. This is the first report in the world of genome editing in a higher polyploid plant, chrysanthemum which has been difficult due to its large genome with very little information available so far. Researchers from the Institute of Vegetable and Floriculture Science, NARO have succeeded in obtaining a chrysanthemum with mutation in yellowish-green fluorescent protein gene inducing reduction in fluorescence by editing the genome of a transgenic chrysanthemum expressing the fluorescent gene and generating axillary bud derived plants. The genome editing technology is expected to become a promising method in improvement and breeding of chrysanthemum cultivars. Read more.
Elucidation of a new mechanism of the Mendelian dominant-recessive interactions between multiple alleles
Press release on 26 Dec 2016
A joint research of the Nara Institute of Science and Technology, NARO Institute of Vegetable and Floriculture Science, Tohoku University, Kobe University, Osaka Kyoiku University and the University of Tokyo revealed for the first time in over 100 years that the Mendelian dominant-recessive interactions between multiple alleles are controlled by polymorphism of small RNAs and their targets. The study based on phenotypic expression of SP11 alleles, which encodes the male determinants of self-incompatibility in Brassica rapa, will be published in the January issue of the journal Nature Plants. Dr. Tomohiro Kakizaki of the Brassicacea Unit, Division of Vegetable Breeding, is the NARO collaborator in this study. Read more.
Compact bunching onion varieties suitable for summer and spring cultivation
Press release on 19 Dec 2016
The NARO has successfully developed compact bunching onion varieties, namely, 'Koiwarabe' and 'Suzuwarabe' that can be stably cultivated from spring to summer. The variety 'Koiwarabe' is characterized by extremely late bolting, hence it is possible to get the stable production from April to June. On the other hand, variety 'Suzuwarabe' grows vigorously even in high summer temperature from July to September. The shape is well maintained and product yield is excellent Read more.
Efficient modification of flower shape and color patterns
Press release on 15 Sep 2016
The NIVFS in collaboration with Kyoto Prefectural University has developed a technology that can efficiently produce flowers with a wide variety of shape and color patterns using genetic recombination. In this study published in the journal Plant and Cell Physiology, different floral organ-specific promoters with different properties were used to generate diverse floral traits using a single chimeric repressor without changing the phenotypes of other organs. This technology developed using torenia plants has the potential for application in other garden plants as well. Read more.
Tsukuba Plant Factory
Presented at the G7 Science Ministerial Meeting, Tsukuba
The NIVFS research on innovative production system in greenhouse horticulture for achieving high year-round yield and low-cost production was presented at the exhibition hall of the G7 Science and Technology Ministers' Meeting held in Tsukuba on May 15-17, 2016. The NARO Tsukuba Plant Factory is a high-yield and high-quality production system for greenhouse vegetables with low cost and low carbon to achieve 50% labor saving and 30% yield growth as compared with the current cultivation practices in Japan. The newly developed Ubiquitous Environment Control System (UECS) has been adopted for environment control and is now in operation. So far, the system has been used to evaluate the optimum control methods and environmental conditions for growing tomato, cucumber, paprika etc.
