22174881-1	2011	BACKGROUND: In Arabidopsis, AGO1 and AGO2 associate with small RNAs that exhibit a Uridine and an Adenosine at their 5" end, respectively.	Adenosine	98-107	Argonaute family protein	Arabidopsis thaliana	37-41	
18342361-5	2008	We found that AGO2 and AGO4 preferentially recruit small RNAs with a 5" terminal adenosine, whereas AGO1 harbors microRNAs (miRNAs) that favor a 5" terminal uridine.	Adenosine	81-90	Argonaute family protein	Arabidopsis thaliana	14-18
