ASR1 is a gene from early auxin-responsive GH3 gene family, and the protein encoded by this gene is overexpressed in the mutant, which results in the following morphological phenotypes including dwarf, epinastic rosette leaves, and restrained lateral root formation, etc. Meanwhile, ASR1 may modify the plant defense signaling molecule salicylic acid in vivo, and therefore asr1 mutant is more susceptible to the infection from the pathogen Pseudomonas syringae.

ASR1属于生长素相关的GH3基因家族，它编码的蛋白质在突变体内过量表达，并造成植株矮化，莲座叶片向下卷曲，侧根发生受到抑制等形态表型的改变，同时，ASR1可能还参与了植物体对抗病信号分子水杨酸的调控或修饰过程，并使asr1突变体对病原菌丁香假单胞杆菌的侵染更敏感。

The results showed that karyotypic type of Ya01-21was 2n=104＝100m+4sm（4SAT）, Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132＝130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.

研究结果表明，崖城01－21的体细胞染色体核型公式为2n＝104＝100m+4sm（4SAT），最长与最短染色体的长度比为4.25，平均臂比1.35，染色体属2C型，分子鉴定结合细胞学研究认为其为斑茅的真实后代，其染色体遗传为n+n；崖城01－36经ITS签定为真实杂种，其体细胞染色体核型公式为2n＝132＝130m+2sm，最长与最短染色体的长度比为3.94，平均臂比1.27，染色体属2B型，结合其性状的进展，推断亲本向其传递染色体可能以2n+n的方式进行。
