Evolutionary History of LTR Retrotransposon Chromodomains in Plants

Table 1

The characteristics of chromodomain-containing Gypsy LTR retrotransposons from Selaginella moellendorffii.

Element name	Element size [bp]	Intact copies	LTRs size [bp]	LTRs identity [%]	TSD	ITR
SM1-Galahad*	~7500	ND	1076/1146	90.2	ND	TG⋯CA
SM2-Galahad	7353	+	919	99.7	CCTAT⋯CCTAT	TGT⋯ACA
SM-Fogey	4916	+	233	98.7	TGCCC⋯TGCCC	TG⋯CA
