A novel class of heat-responsive small RNAs derived from the chloroplast genome of Chinese cabbage (Brassica rapa)

Table 2 Heat response of tRNA-derived csRNAs

Group	tRNA	Heat response	Percentage (%) ^a
			MT	HT
I	Ala,Asp,Phe,Lys,Leu,Gln,Thr,Val	Shorter csRNAs increased, and longer csRNAs decreased ^b	81	73
II	Cys,Glu,Ile,Met,Asn,Pro,Ser,Trp	Shorter csRNAs increased, and longer csRNAs unchanged	12	20
III	His,Arg	Longer csRNAs decreased, and shorter csRNAs unchanged	5	5
IV	Gly	18 nt csRNAs decreased, and the others unchanged	2	2

^a: Percentage for each group in total abundance of tRNA-derived csRNAs.
^b: The shorter csRNAs ranged from 15 to 25 nt in length, and the longer csRNAs were from 29 to 32 nt.
