The TAS3 loci identified in watermelon. a The sequence and genomic locus of TAS3a and TAS3b. The red and blue region are the 5’ and 3’ miR390 complementary sites. The yellow and black regions in upper cases are the tasiRNAs that target ARF genes. b The 5’ miR390 site on TAS3a and TAS3b. c The 3’ miR390 site on TAS3a and TAS3b. d The distribution of degradome reads on TAS3b transcript. The two positions pointed by red and blue arrows correspond to the 5’ and 3’ miR390 site shown in Part b and c, respectively. e The distribution of small RNA reads in the small RNA profile of mixed tissues (GSM936361) on TAS3b. f The tasiRNAs that target ARF genes in TAS3a and TAS3b, named by following the scheme in [15]. g Four ARF genes that are targeted by TAS3 derived tasiRNAs. h The T-plot of and complementary sites of TAS3a_D8(+):Cla000557. i The T-plot of and complementary sites of TAS3a_D8(+):Cla009652. In Part h and i, the x-axis is the position on the transcript, and y-axis is the number of reads detected from a position. The arrows in the upper parts correspond to the positions pointed by the arrows of the same colors in the lower parts
