چکیده
Abstract Taiwania ( cryptomerioides Hayata) has long been regarded as a living fossil from the Tertiary period of Mesozoic Era for its distinguished yellowish-red color with purplish-pink streaks presented in heartwood. With this elegant appearance that matches “red” good fortune Taiwanese culture, is supposed to be popular wood Taiwan where it native species of. Extractives contribute properties wood. It fascinating subject investigate extractives biosynthesis process heartwood formation. Up date, there no phytochemistry study sapwood. In study, three new sesquiterpenoids, A 1 ), B 2 and C 3 together 75 known compounds The structures were determined by analysis spectroscopic data comparison literatures. This supported secondary reaction lignans could found sapwood confirmed our previous research on Taiwania-type

Establishment of expressed sequence tags from Taiwania (Taiwania cryptomerioides Hayata) seedling cDNA
Taiwania (Taiwania cryptomerioides Hayata), native to Taiwan, is one of the “living fossils” from the Tertiary period of the Cenozoic era. To isolate genes involved in wood formation and biochemical synthesis from this tree, 436 randomly selected clones from a cDNA library derived from seedling were sequenced and analyzed firstly. Contig analysis of these expressed sequence tags (ESTs) identifi...
