We developed PCR primers to detect Cylindrocladium quinqueseptatum which infect Eucalyptus causing leaf and seedling blight resulting in heavy seedling mortality in North Indian states. Primers based on sequence analysis of internal transcribed spacer region 1 and 5.8S of ribosomal DNA produced PCR product of 245bp. The internal transcribed spacer (ITS) of the ribosomal DNA (rDNA) sub unit repe...

Ralstonia solanacearum and R. pseudosolanacearum are well known primary pathogens of herbaceous crops. Reports of wilt caused by these pathogens in tree species are limited other than on Eucalyptus species. Despite the widespread occurrence of so-called bacterial wilt on eucalypts in tropical and sub-tropical parts of Africa, Asia, and the Americas, there remain many contradictions relating to ...

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

The authors wish to express their appreciation for the work of Kimberly Wilburn and Cora ~isniewski, without whose dedication and willing attitude this paper could not have been completed. Due to their exceptional efforts and skill; we were able to dispatch a lengthy study to meet an imposed deadline. We would also like to thank all of the Census Bureau, for their valuable comments. The views e...

The following aromatic plants of Greek origin, Origanum dictamnus (dictamus), Eucalyptus globulus (eucalyptus), Origanum vulgare L. (oregano), Mellisa officinalis L. (balm mint) and Sideritis cretica (mountain tea), were examined for the content of phenolic substances. Reversed phase HPLC coupled to diode array detector (DAD) was used for the analysis of the plant extracts. The gas chromatograp...
