Oenothera hookeri

Chudzik B, Sniezko R. Similarities in some phenomena connected with maturation of crassi- and tenuinucellar ovules (Oenothera hookeri and brevistylis, Sinapis alba, Brassica napus, Galanthus nivalis). XV International Congress on Sexual Plant Reproduction, August 16-21, Wageningen, Germany, 1998. 

Two genes (psbE and psbF) for polypeptides of Cyt b-559 have been,located and characterized from spinach [56], wheat [57], tobacco [58], Oenothera hookeri [58] and pea (D.L. Willey, unpublished). The gene for the 9 kDa polypeptide known to be associated with Cyt b-559 preparations was first of all located in spinach [59] and wheat [57] by hybrid-release translation or by coupled transcription-translation of fragments of chloroplast DNA. Nucleotide sequencing [56,57] revealed an open reading frame of 83 codons, encoding a protein with the known N-... 

The petals of flowers of Oenothera hookeri ssp. venusta contain only carotenoids in the distal ends, but the basal portions contain the chalcone isosalipurposide (16) (Dement and Raven, 1974).
