Myronivska 808 (a Ukrainian selection)—a variety, sensitive to pathogen action; Roazon (a French selection)—a relatively resistant variety, which has the highest level of resistance in the world; and.
In our previous study (Hur et al. 2016), the japonica germplasm Wonsaedaesoo showed the highest level of resistance (ratio of healthy plants was 97%) among the 254 rice germplasm accessions examined, and it showed a higher level of resistance than that of another bakanae-resistant plant Shingwang (ratio of healthy plants was 77%).
Among all mutations investigated affecting base-pair interaction C1409-G1491, transversionsion mutations G1491C and G1491U (resulting in pyrimidine-pyrimidine oppositions) confer the highest level of resistance, in particular to paromomycin.
In addition, the highest level of resistance was observed to nalidixic acid whereas no resistance to ciprofloxacin was observed.
The highest level of resistance (six antimicrobial drugs) was detected in 7% of Shigella isolates and included ampicillin, chloramphenicol, streptomycin, sulfisoxazole, tetracycline, and trimethoprim-sulfa.
We found that bacterial strains exhibited the highest level of resistance to metronidazole (77.96%), amoxicillin (67.79%), ampicillin (61.01%), and tetracycline (59.32%).
Carbetamide-resistant populations had a higher level of resistance than atrazine-resistant populations (T6 = 4.854, P < 0.01).
These mechanisms that generally cause the highest levels of resistance have been usually found in insects selected for resistance to a single or few Cry proteins [4]; [4]].
