1 to 4 are arabidopsis leaf ,5 to 8 are arabidopsis root

why there are so many bands in leaf tissue,and what is the band in front of 28s rRNA

Depending on your isolation additional bands are to be expected, especially in very active tissues. For quality control one usually would check the 28/18s ratio. Very high MW bands can also be co-isolated DNA.

thanks for your reply, does it have such a possibility that the chlorophy body rRNA and chondriosome rRNA are extracted from leaf tissue meanwhile
