Several Nicotiana species and cultivars, with and without the N gene, were screened for the effect of polyacrylic acid (PAA) and salicylic acid (SA) on b-protein production and induced resistance. Whilst SA was effective in producing either b-proteins and resistance to a challenge viral infection in all the cultivars tested, the effectiveness of PAA appeared cultivar dependent. Only the cultivars Xanthi-nc (NN), Xanthi (nn) and hybrids between Xanthi-nc (NN) and other N. tabacum cultivars responded to PAA. This is the first time that the genetic determinant for the PAA response has been shown to be sexually transmitted as a dominant character, and also that it is distinct from the N gene.
对几种有或没有N基因的烟草属物种和品种进行了筛选，以研究聚丙烯酸（PAA）和水杨酸（SA）对β蛋白产生和诱导抗性的影响。虽然SA在所有测试品种中都能有效产生β蛋白并对挑战性病毒感染产生抗性，但PAA的有效性似乎因品种而异。只有品种Xanthi-nc（NN）、Xanthi（nn）以及Xanthi-nc（NN）与其他烟草品种之间的杂交种对PAA有反应。这是首次表明PAA反应的遗传决定因素作为显性性状通过有性方式传递，并且它与N基因不同。
