Comparative transcriptome analysis of the wild-type model apomict Hieracium praealtum and its loss of parthenogenesis (lop) mutant

Table 1 Information of developmental events in sampled capitula stages of R35, lop138 and A36

Species	Accession Id	Parthenogenesis	Sample code	Capitulum stage	Developmental events ^#
Hieracium praealtum	R35	Capable	Ovary_3	3	Tetrads of megaspores present, AIs differentiating
			Ovary_4	4	Meiosis suppression, meiotic tetrads degenerating and AIs enlarging
			Ovary_5	5	Embryo sacs develop from AIs through mitosis
			Ovary_6	6	Mature embryo sacs developed. Some undergo spontaneous embryogenesis.
			Ovary_7	7	Embryo and endosperm development occur in many ovules.
			Ovary_8	8	Ovules contain early to globular embryos
			Ovary_9	9	Ovules contain early to globular embryos
			Ovary10	10	Senescence begins. Ovules contain globular to late globular embryos.
			Wt_E1	5	Embryo sacs develop from AIs through mitosis
			Wt_E2	5	Embryo sacs develop from AIs through mitosis
			Wt_L1	7	Embryo and endosperm development occur in many ovules.
			Wt_L2	7	Embryo and endosperm development occur in many ovules.
	lop138	Not capable	Lop_E1	9 (not pollinated)	Mature embryo sacs containing quiescent egg cell
			Lop_E2	9 (not pollinated)	Mature embryo sacs containing quiescent egg cell
			Lop_L1	12 (after pollination)	Ovules contain globular to heart? embryos
			Lop_L2	12 (after pollination)	Ovules contain globular to heart? embryos

H. aurantiacum	A36	Capable	Pol_L2	10	Ovules contain globular to heart stage embryos

^# Description of developmental events for R35 and A36 was based on [9, 51] and observations from the current study and [16] were used for lop138
