China’s entrance to the World Trade Organization and trend towards globalization of its economy and finance has increased international trade, especially in agriculture and forestry products. Plant inspection and quarantine has correspondingly grown and developed in importance. In this paper, plant quarantine in Shenzhen, including its team, detection platforms, inspection protocols, scientific research, achievements and collaborations will be introduced. The Plant Inspection and Quarantine Laboratory in Shenzhen City is now one of the largest laboratories in this field in China. Two national and regional key laboratories have been built, ranking top both in inspection capacity and routine inspection. In 2010, more than 70,000 imported products were inspected, and more than 30,000 pest-infected products were intercepted. By carrying out scientific research and cooperating domestically and abroad, the laboratory is leading the way in the development of standard methods for standard pest testing using morphology, molecular biology and immunology. The Shenzen Inspection and Quarantine Bureau therefore facilitates the testing of pests in imported commodities and contributes to the safe and efficient international trade in grains, fruits, seeds, seedlings and other plants and plant products.

The powdery mildew Erysiphe platani was recorded on London plane (Platanus × acerifolia) in Germany. Ascomata and conidia were found on a leaf of a tree at an avenue in the city of Frankfurt am Main, which had also been colonized by the invasive Sycamore Lace Bug Corythucha ciliata. The spread of both invasive species from south Europe towards the north might be correlated with global warming. Difficulties in detecting and identifying the mildew as the causative agent of the symptoms are presented. Information relevant for the diagnosis and prognosis is compiled and discussed.

The genus Schiffnerula is represented by 80 species in India belonging to the anamorphs Mitteriella (single species, assigned to Schiffnerula ziziphina), Questieriella (10), Sarcinella (39) and the teleomorph Schiffnerula (31). Of these, Sarcinella loranthacearum, Schiffnerula cryptostegiae, Schiffnerula flacourtiae, Schiffnerula lagerstroemiae and Schiffnerula meliosmatis are proposed as new species and a new family, Schiffnerulaceae is proposed to accommodate Schiffnerula. All the taxa are described and illustrated in detail.

The definition of endophytes ranges from symbiotic to balanced antagonism and/or latent plant pathogens. This indicates a close affiliation between endophytes and pathogens but molecular evidence confirming these relationships are still to be elucidated. We investigated the relationship of endophytic, saprobic and pathogenic Fusarium species as a model genus based on ITS sequences and ITS2 secondary structure analysis. Altogether 212 Fusarium species mostly named in GenBank with ranging lifestyles were used in this study. Species deposited in GenBank were found to be often wrongly named based on sequence comparison as species with the same names were polyphyletic, while differently named species often had the same sequences. Phylogenetic analysis by three different methods (UPGMA, NJ and MP) revealed that similar named species clustered together, but did not form well distinct clades reflective of their lifestyles. Several species were polyphyletic, while several other unrelated species appear to share the same ITS sequences. Since ITS rDNA sequence based phylogeny did not showed distinct relationships, ITS2 consensus secondary structures were used. Endophytes showed close molecular structural affinity with pathogens but structural features of saprobes was very different. Although care must be taken when using sequences from named Fusarium species in GenBank this study provides molecular evidence that endophytes share a close relationship with pathogens and agrees with the assumption that endophytes are latent pathogens.
