BiWB disease occurs widely across the area in which B. polycarpa are grown, especially in Zhejiang, Anhui, and Jiangxi provinces of China. Visible symptoms on diseased trees include reduced leaf size, yellowing and reddening of leaves, internode shortening, lateral bud proliferation, and development of branch … See more The characteristic blue fluorescence in the phloem tissues was observed in the young stem, petiole, and veins of leaves from diseased B. polycarpa trees, while no phytoplasma-specific … See more The predicted 1.8-kb PCR product from symptomatic B. polycarpa was amplified by PCR using BiWB phytoplasma DNA as the template. The 1.2-kb partial rp gene fragment and the 0.85-kb partial tufgene fragment were … See more Partial tuf and rp gene fragments approximately 1.2- and 0.85-kb long, respectively, were amplified from the BiWB phytoplasma. Sequence similarity analyses of the tuf and rp genes were conducted. Based on … See more An analysis of the 1.8-kb sequence amplified by the primer pair P1/P7 showed that there was a 46.3 % GC content in the Zhejiang (ZJ), Anhui (AH), and Jiangxi (JX) strains of BiWB, … See more WebIn a pot study, we tested the effects of two non-N2-fixing (Bischofia polycarpa (Levl.)

Webwith B. polycarpa (Lévl.) Airy Shaw in many Chinese plant publications. Wherever bishop wood is mentioned, it may be followed by either Bischofia javanica Bl. or B. polycarpa (Lévl.) Airy Shaw. Description B. javanica is an evergreen or semi-evergreen woody tree with a maximum height of 40 m and diameter of 2.3 m. WebTwo techniques were developed for the analysis of non‐cultivable mollicutes in insects and signals generated by ribosomal DNA of organisms which appear to be closely related but not identical to phytoplasmas were detected. Two techniques were developed for the analysis of non‐cultivable mollicutes in insects. The first was aimed at detecting organisms … http://www.worldfloraonline.org/taxon/wfo-0000342312 how does a thermometer work
