Towards male sterility in Cryptomeria japonica using the male strobilus-specific genes of C. japonica
Background Cryptomeria japonica D. Don (sugi) is one of the most important Japanese conifer species. Rapid improvement of the wood trait (e.g., growth speed and wood quality) using a conventional breeding approach is not possible, because breeding of coniferous tree requires a very long time. Genetic modification might be a powerful tool to shorten the time needed to breed trees compared with t...
متن کاملOryzalin-induced Tetraploidy in Cryptomeria japonica (Cupressaceae)
Japanese-cedar [Cryptomeria japonica (L.f.) D. Don] represents an alternative to leyland cypress [·Cuprocyparis leylandii (A.B. Jacks. & Dallim.) Farjon] as an evergreen screen or specimen plant for landscapes. It performs well under a range of soil and environmental conditions but has been underused attributable, in part, to unsightly winter browning caused by photoinhibition. In previous stud...
متن کاملComprehensive analysis of small RNAs expressed in developing male strobili of Cryptomeria japonica
Deep sequencing of small RNAs (sRNAs) in developing male strobili of second-generation offspring originating from a nuclear genic male sterile tree of Cryptomeria japonica were performed to characterize sRNA populations in the male strobili at early pollen developmental stages. Comparing to sequences of microRNA (miRNA) families of plant species and sRNAs expressed in the reproductive organs of...
متن کاملGenetic Differentiation and Evolutionary Adaptation in Cryptomeria japonica
Local adaptation of plant species is a central issue for survival during global climate change, especially for long-lived forest trees, with their lengthy regeneration time and spatially limited gene flow. Identification of loci and/or genomic regions associated with local adaptation is necessary for knowledge of both evolution and molecular breeding for climate change. Cryptomeria japonica is ...
متن کاملIsolation of antibacterial diterpenoids from Cryptomeria japonica bark.
The aims of the present study were to determine the antibacterial activity of bark extract of Cryptomeria japonica D. Don and to isolate potential antibacterial constituents. The results showed that the ethanolic extract of C. japonica bark possessed a good antibacterial activity. Nine compounds including seven diterpenoids (ferruginol (I), isopimaric acid (II), iguestol (III), isopimarol (IV),...
