基因pg-11赋予成年植物燕麦茎锈病抗性的表达与叶和茎组织中叶绿素和类胡萝卜素色素的减少有关。具有pg-11基因的幼苗对茎锈病敏感，并且色素水平接近正常，但随着年龄的增长，色素含量比没有该基因的植物下降得更快，并且植物对茎锈病具有中等抗性。叶绿素与类胡萝卜素的比例在植物发育的各个阶段都保持不变。该基因与任何其他已知的燕麦抗茎锈病基因不同。
The expression of adult plant oat stem rust resistance conferred by genepg-11is associated with a reduction of chlorophyll and carotenoid pigments in the leaf and stem tissue. Seedlings that possess genepg-11are susceptible to stem rust and have near normal pigment levels but with increasing age the pigment content decreases more rapidly than in plants without the gene and the plants become moderately resistant to stem rust. The ratio of chlorophyll to carotenoids remains unchanged at all stages of plant development. This gene has effects unlike any other known gene for stem rust resistance in oats.
