Origin of Prunus x yedoenins 'Somei-yoshino' based on sequence analysis of PolA1 gene	2015	7	.pdf	application/pdf	4473	261	67	To reveal the origin of ‘Somei-yoshino,’ we analyzed sequences of intron 19 and exon 20 of PolA1, a single-copy nuclear gene encoding the largest subunit of RNA polymerase I. One of two exon 20 sequences found in ‘Somei-yoshino’ was the same as that of P. pendula, whereas the other sequence was shared with several taxa in seven wild species, including P. jamasakura and P. lannesiana. A to- tal of 42 individuals of nine wild species native to Japan (Table 1) were analyzed; P. apetala (three individuals), P. incisa (four), P. nipponica (four), P. jamasakura (eight), P. sargentii (two), P. verecunda (four), P. lannesiana (three), P. maximowiczii (three), and P. pendula (six), and three alien wild species, P. campanulata (two), P. cerasoides (two), and P. pseudo-cerasus (one) (Table 1).	cache/ahs-3013.pdf	txt/ahs-3013.txt
