As R genes recognise very specific products, introgression and sub- sequent employment of a new R gene puts selective pressure on the pathogen to evolve in such a way that it is no longer recognised by the host plant. Therefore, R- gene based resistance is often breached by new, virulent,...
In this case, the five most fre- quent words are: • Classification: this word is found in the first position, because research work considers that it is often essential to classify the type of disease considered before any sub- sequent reasoning. • Diagnosis: this word is found in ...

Here is the numbers I've got: rebuilding indexes sequentually consistently took 76 sec., while using dbms_job.submit() calls took around 40 - 42 sec. I said "around", because the technique I used may not be perfect, though it
Another striking example is the case of Buellia violaceofusca and Lecanographa amylacea, which were previously synonymised [64]. These taxa have identical nuITS and intermixed mtSSU sequences but contain phylogenetically distant photobionts (Trebouxia vs. trentepohlioid). Though the signal in ...
