Wild type M. tuberculosis H37Rv and a known PZA-resistant mutant PZA-R1 containing a pncA mutation (Q10P) were included as a drug susceptible control strain and a resistant control strain for the PZA susceptibility testing.
The rice variety CO39 was used as a susceptible control.
PTB33 (carrying Bph3) is a resistance control and TN1 is a susceptible control.
The CO39 variety was used as a susceptible control for rice blast evaluation.
By contrast, the susceptible control cultivar CO39 was susceptible to 27 of all 28 tested isolates.
Bph = Severity scores with UBN biotype at 9 DAI when TN1, the susceptible control died.
Damage scores were recorded when the susceptible control, 'TN1', died (9 days after infestation; 9DAI), using the standard evaluation system (IRRI 1996).
b Photograph of the disease reaction of introgression lines of b IR126181, c IR126183, d IR126184 and a susceptible control CO39.
Cluster analysis based on ISSR markers resulted in two major groups, (i) resistance sources, and (ii) the susceptible control and hybrid parental lines.
b The performance (showing the damage degree) of HB13002-5-30-10 (andelected Nits and itwotwo derived hybrids, Huahui938 (recurrent parent) and its two derived hybrids, B5 (donor parent), Luohong4A, TN1 (susceptible control) and Fengliangyou4 (a popular hybrid).
While the recurrent parent 93 11 and susceptible control TN1 died completely, LuoYang69, along with NIL-Bph6 and NIL-Bph9, showed high levels of resistance to BPH (Fig. 2a).
