-- SPON Young & MacArthur 1947 Texas Ag Exp Sta Bul 698; Wo= HD-ZIP IV transcription factor (Gao et al 2017 Pl Sci 262:103; Wu et al 2024 Science 384:124). All vegetative parts, including hypocotyl densely tomentose, the long hairs being more abundant, branched, and stellate, but no longer than normal. Increased development of other hair types. Homozygous inviable, rarely surviving past cotyledon stage. Homozygous seedlings exceedingly tomentose and with abnormally thick and shortened hypocotyl and cotyledons. Style shortened compared to wild type.
Hair modifications: augmentation, reduction, distortion or elimination Yes
Flower form or color No
m Morgan SPON Rick & Butler 1956 Adv Genet 8:267. In cv. Rutgers. Yang et al 2011:LOF mutant in Solyc02g080260 Pelage on all parts wooly but less so than Wo; homozygotes are viable, heterozygotes intermediate.
Hair modifications: augmentation, reduction, distortion or elimination Yes
Flower form or color No
mz Mel Zobel SPON Rick 1979 TGC 29:32. Spontaneous in VF145-7979 All parts densely pubescent; leaves have a velvety, wilty appearance; resembles Wo^m and is homozygous viable.
