In the context of biocontrol of plant diseases, the three families of Bacillus lipopeptides - surfactins, iturins and fengycins were at first mostly studied for their antagonistic activity for a wide range of potential phytopathogens, including bacteria, fungi and oomycetes. Recent investigations have shed light on the fact that these lipopeptides can also influence the ecological fitness of the producing strain in terms of root colonization (and thereby persistence in the rhizosphere) and also have a key role in the beneficial interaction of Bacillus species with plants by stimulating host defence mechanisms. The different structural traits and physico-chemical properties of these effective surface- and membrane-active amphiphilic biomolecules explain their involvement in most of the mechanisms developed by bacteria for the biocontrol of different plant pathogens.

Results presented in this paper describe the ability of Bacillus subtilis strain M4 to reduce disease incidence caused by Colletotrichum lagenarium and Pythium aphanidermatum on cucumber and tomato, respectively. Disease protection in both pathosystems was most probably due to induction of resistance in the host plant since experiments were designed in order to avoid any direct contact between the biocontrol agent and the pathogen. Pre-inoculation with strain M4 thus sensitised both plants to react more efficiently to subsequent pathogen infection. In cucumber, the use of endospores provided a disease control level similar to that obtained with vegetative cells. In contrast, a mixture of lipopeptides from the surfactin, iturin and fengycin families showed no resistance-inducing potential. Interestingly, treatment with strain M4 was also associated with significant changes in gene transcription in the host plant as revealed by cDNA-AFLP analyses. Several AFLP fragments corresponded to genes not expressed in control plants and specifically induced by the Bacillus treatment. In support to the macroscopic protective effect, this differential accumulation of mRNA also illustrates the plant reaction following perception of strain M4, and constitutes one of the very first examples of defence-associated modifications at the transcriptional level elicited by a non-pathogenic bacterium in a host plant.

This paper seeks to uncover an inconvenient truth. The Microsoft decisions are not tying cases. Rather, the two decisions taken by the EU Commission against Microsoft – i.e. the Windows Media Player (“WMP”) case of 2004 and the Internet Explorer (“IE”) case of 2009 – mark departures from conventional tying analysis (I). First, they deviate from standard tying law in that in the Microsoft cases, a key component of abusive tying, namely coercion, is missing (II). Second, the Microsoft decisions share many analogies with “essential facility” cases. One may thus question to what extent the Commission has not pursued disguised refusal to supply cases (III).

Lysozyme from lambda bacteriophage (lambda lysozyme) is an 18 kDa globular protein displaying some of the structural features common to all lysozymes; in particular, lambda lysozyme consists of two structural domains connected by a helix, and has its catalytic residues located at the interface between these two domains. An interesting feature of lambda lysozyme, when compared to the well-characterised hen egg-white lysozyme, is its lack of disulfide bridges; this makes lambda lysozyme an interesting system for studies of protein folding. A comparison of the folding properties of lambda lysozyme and hen lysozyme will provide important insights into the role that disulfide bonds play in the refolding pathway of the latter protein. Here we report the (1)H, (13)C and (15)N backbone resonance assignments for lambda lysozyme by heteronuclear multidimensional NMR spectroscopy. These assignments provide the starting point for detailed investigation of the refolding pathway using pulse-labelling hydrogen/deuterium exchange experiments monitored by NMR. [less ▲]

This contribution summarizes considerations developed to allow a reasonable and consistent definition of the national parameters to be introduced in the Belgian national annex to chapter 9 of Eurocode 8 dealing with seismic design of masonry structures. The different aspects considered are material properties (resistance and ductility), detailing of wall-wall and wall-floor connections and rules for simple masonry buildings. The result is a set of rules consistent with the national practice and defining (i) what is allowed in Belgium for the different seismic zones, (ii) minimal requirements for simple non-engineered buildings and (iii) a procedure that can be followed to improve these rules for materials and structural systems exhibiting better properties than the minimal requirements of Eurocode 8.
