Sex Distribution of Paper Mulberry (Broussonetia papyrifera) in the Pacific
BACKGROUND Paper mulberry (Broussonetia papyrifera (L.) L'Hér. ex Vent) is a dioecious tree native to East Asia and mainland Southeast-Asia, introduced prehistorically to Polynesia as a source of bark fiber by Austronesian-speaking voyagers. In Oceania, trees are coppiced and harvested for production of bark-cloth, so flowering is generally unknown. A survey of botanical records of paper mulber...
متن کاملEfficient transformation of Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica.
We used a modified version of the method of Hanahan (D. Hanahan, J. Mol. Biol. 166:557-580, 1983) to transform Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica with the plasmids pBR322, pBR325, and pAT153. The transformation frequency ranged from 1 X 10(2) to 4 X 10(4) colonies per micrograms of plasmid DNA. The nature of these transformants was confirmed by plasmid ana...
متن کاملBiological Control of Erwinia carotovora ssp. carotovora by Streptomyces Species
Ten isolates of Erwinia carotovora ssp. carotovora (Ecc) were isolated from infected potato tubers of Picasso, Sante, and Nevskiy varieties collected from different regions in Kyrgyzstan. Isolates were identified as Erwinia carotovora ssp. carotovora (Ecc) by standard bacteriological techniques and pathogenicity tests on tubers and also by PCR analyses. Tests on the pathogenicity of E. carotovo...
متن کاملLinen Most Useful: Perspectives on Structure, Chemistry, and Enzymes for Retting Flax
The components of flax (Linum usitatissimum) stems are described and illustrated, with reference to the anatomy and chemical makeup and to applications in processing and products. Bast fiber, which is a major economic product of flax along with linseed and linseed oil, is described with particular reference to its application in textiles, composites, and specialty papers. A short history of ret...
متن کاملPolygalacturonase of Erwinia carotovora.
The polygalacturonase, clearly differentiated from polygalacturonic acid trans-eliminase, produced in the culture fluid of Erwinia carotovora was purified 56-fold by means of acetone precipitation, acetate butfer extraction, and two successive treatments by chromatography on carboxymethyl cellulose. The purified enzyme is specific for nonmethoxylated polygalacturonic acid. It shows an optimum p...
