Karyotype studies on Lycoris radiata populations from China.
Lycoris radiata is an important medicinal and ornamental plant of China. In the present study, somatic chromosome counts and karyotype analyses, which are important aspects of plant phylogeny and evolution, were performed in 466 individuals from 25 L. radiata populations by root tip squash method. Chromosome counts revealed that 10 populations were diploid (2n = 2x = 22) and 15 were triploid (2...
متن کاملTwo new amaryllidaceae alkaloids from the bulbs of Lycoris radiata.
Two new Amaryllidaceae alkaloids, named lycoranines A (1) and B (2), were isolated from the bulbs of Lycoris radiata. Their structures were elucidated on the basis of extensive spectroscopic analysis. Compound 2 was a new-type alkaloid, which provided a new insight into the biosynthesis of alkaloids in Amaryllidaceae plants.
متن کاملMechanism of Resistance in Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] to bruchids, Callosobruchus spp. (Coleoptera: Bruchidae)
Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] is an important pulse crop in Asia, and is consumed as dry seeds and as bean sprouts. It is an excellent source of digestible protein. Bruchids [Callosobruchus chinensis (L.) and Callosobruchus maculatus (F.)] are the important pests of mungbean and cause damage in the field and in storage. Bruchid infestation reduces the nutritional and mar...
متن کاملPolymorphic microsatellite loci for the genetic analysis of Lycoris radiata (Amaryllidaceae) and cross-amplification in other congeneric species.
Lycoris radiata is a perennial herb that has been used in traditional Chinese medicine for a long time and has two main medicinal components in its bulb, lycorine and galanthamine. However, the original microsatellite loci have not been developed for any species of Lycoris. Total genomic DNA was extracted from fresh bulbs using a modified CTAB protocol. We isolated 10 microsatellite loci ...
متن کاملCloning and heterologous expression of a new 3'-hydroxylase gene from Lycoris radiata.
A full-length cDNA (LC3'H) was obtained from a cDNA library of Lycoris radiata by DOP-PCR (degenerate oligonucleotide primer PCR), 3'race and 5'race methods. Compared with the other reported enzymes from different plants, the deduced amino acid sequence of LC3'H exhibits significant homologies to 3'-hydroxylases that are involved in the caffeic acid biosynthesis. These findings suggest that the...
