In the moderately resistant TAG5, basal levels of SA were found be significantly higher than the susceptible ZG14 basal levels at all the investigate time points.
Although MPK3 was not DE in the moderately resistant TAG5, the expression level in terms of FPKM values of the gene was comparable between both genotypes following pathogen challenge.
RR values were categorized in four resistance levels: sensitive (RR ≤ 2), moderately resistant (2 < RR ≤ 4), resistant (4 < RR ≤ 10), or highly resistant (RR > 10) 26.
Based on the results of the weevil biological parameters and dry mass consumed provided by univariate and multivariate statistical analyses, the bean genotypes were classified into four levels of resistance (antibiosis): highly resistant, moderately resistant, susceptible and highly susceptible.
SA was found to occur at significantly higher basal levels in the moderately resistant host TAG5, than in the susceptible ZG14 at all the time points however, following inoculation, SA decreases in TAG5 at 3 dpi but remains constant in ZG14.
R resistant, MR moderately resistant, MS moderately susceptible, S susceptible Fig. 5 Photograph of resistance level to BPH of improved Jin 23B at the tillering stage (the 25 days after infested with BPH).
The resistance data of these lines were obtained in our previous study of seeding resistance aAccession numbers in the IRRI genebank bIND (India), PHL (Philippines), LKA (Sri Lanka) cResistance scores at seedling stage dResistance level, HR (highly resistant), R (resistant), MR (moderately resistant), MS (Moderately susceptible), S (susceptible).
The resistant lines L. cerasiforme, S. commersonii, CRA 66 and Hawaii 7996 always had higher levels of gene expression than the moderately resistant MST 32/1 cultivar and the susceptible Quatre carrées and Spunta cultivars.
Progressing sequentially through increasingly higher doses of antibiotic, low-resistance mutants gave rise to moderately resistant mutants, eventually spawning highly resistant strains able to fend off the highest doses of antibiotic.
Different genotypes of grapes show varying level of resistance to PV, ranging from susceptible V. vinifera, to the moderately resistant V. rupestris and V. amurensis, V. cinerea, V. riparia and V. candicans, to the totally resistant Muscadinia rotundifolia [ 4- 6].
