In biological classification, the term subspecies refers to one of two or more populations of a species living in different subdivisions of the species' range and varying from one another by morphological characteristics. A single subspecies cannot be recognized independently: a species is either recognized as having no subspecies at all or at least two, including any that are extinct. The term may be abbreviated to subsp. or ssp. The plural is the same as the singular: subspecies.
Agrobacterium mediated transformation of moulds, in particular those belonging to the genus Aspergillus
The invention relates to Agrobacterium mediated transformation of moulds comprising species of the fungal sub-divisions Ascomycotina, Basidiomycotina, Deuteromycotina, Mastigomycotina, and Zygomycotina.Examples demonstrate the transformation of Aspergillus awamori (both protoplasts and conidia), Aspergillus nidulans, Aspergillus niger, Colletotrichum gloeosporioides, Fusarium solani pisi, Neurospora crassa, Trichoderma reesei, Pleurotus ostreatus and Agaricus bisporus (all conidia), and Fusarium graminearum (both conidia and rehydrated freeze dried ATCC material).Especially for Aspergillus awamori the transformation frequency is much higher than with conventional mould transformation techniques.It has further been found that not only one expressable gene can be introduced into these moulds, but even multiple copies of such gene, which, moreover, can be targeted e.g. in the chromosomal pyrG locus, as exemplified for A. awamori. These multiple copies can be of a gene encoding a desired, homologous or heterologous, protein.

The use of free, extractable lipids found in bacteria for identification of bacterial species and subspecies is described. Bacteria have been found to differ sufficiently in their extracted lipid compositions to effect identification using thin layer chromatographic techniques. Burkholderia pseudomallei, Burkholderia thailandensis, and Burkholderia mallei have been distinguished in this manner. Lipopeptides specific to Mycobacterium avium subspecies paratuberculosis, but not to the closely related bacterium Mycobacterium avium subspecies avium have also been used as a basis for bacterial subspecies identification using mass spectrometry and seroreactivity. Mass spectrometric analysis of total bacterial lipids of Burkholderia pseudomallei, Burkholderia thailandensis, and Burkholderia mallei, and mass spectrometric analysis of total bacterial lipids for Mycobacterium avium subspecies paratuberculosis and Mycobacterium avium subspecies avium, without further lipid separation, has shown that species and subspecies of bacteria may be identified using such analysis.
