LF10-lar1LF10-lar1
M. lewisii
flower, Anthocyanin pigmentationA near-isogenic line (NIL) in the LF10 background, with the LAR1 locus substituted by the M. cardinalis CE10 version. LAR1 encodes a subgroup-7 R2R3-MYB that activates flavonol biosynthesis.
Reference: Yuan et al. 2016. PNAS 113: 2448–2453.
LF10-roi1LF10-roi1
M. lewisii
flower, Anthocyanin pigmentationA near-isogenic line (NIL) in the LF10 background, with the ROI1 locus substituted by the M. cardinalis CE10 version. ROI1 encodes an R3-MYB that represses anthocyanin biosynthesis.
Reference: Reference: Yuan et al. 2013. Genetics 194: 255-263.
ML10082guideless
M. lewisii
flower, Carotenoid pigmentation, trichomeMutation in a Mixta-like (Subgroup 9) R2R3-MYB gene. Trichomes on the petal are very short and stunted. Conical cells on the inner epidermis become flatter. Carotenoids in the nectar guides are much reduced.
Reference: Yuan et al. 2013. Genetics 194: 523-528.
ML10346rcp1-1
M. lewisii
flower, Carotenoid pigmentationMutation in a subgroup 21 R2R3-MYB gene. Carotenoid content in the nectar guides is substantially reduced compared to the wild-type.
Reference: Sagawa et al. 2016. New Phytologist. 209: 1049-1057.
ML10422fns-1
M. lewisii
flower, Anthocyanin pigmentationMutation in the Flavone Synthase (FNS) gene, causing an over-dominance in flower color intensity.
Reference: LaFountain et al. 2017. G3. 7: 3947-3954
ML10863pelan/boo3
M. lewisii
flower, Anthocyanin pigmentationMutation in a subgroup 6 R2R3-MYB gene. Anthocyanin production is abolished in petal lobes, but not affected in other tissues, including the nectar guides.
Reference: Yuan et al. 2014. New Phytologist. 204: 1013–1027.
ML11431wd40a-1/boo5
M. lewisii
flower, Anthocyanin pigmentationMutation in the WD40a gene, encoding an indispensable component of the anthocyanin-activating MYB-bHLH-WD40 complex. Anthocyanin production is abolished in all tissue types.
Reference: Yuan et al. 2014. New Phytologist. 204: 1013–1027.
ML11689corolla lobeless
M. lewisii
flower, Corolla limbThe distal portion of lateral organs is less developed, most conspicuously the corolla lobes.
ML12255cheekless1
M. lewisii
flower, whole plantCotyledons are fused. Some leaf pairs are fused too. Flowers have reduced number of petals, usually 3, sometimes less, but the ventral petal is always present.
ML12267chsa-1/boo12
M. lewisii
flower, Anthocyanin pigmentationA mutation in the CHSa gene that abolishes anthocyanin production in all tissue types throughout the plant. A strong chsa allele.
ML12314dfr-1
M. lewisii
flower, Anthocyanin pigmentationA mutation in the DFR gene that abolishes anthocyanin production in all tissue types throughout the plant. A strong dfr allele.
ML12378cheekless2
M. lewisii
whole plant, flowerAllelic to cheekless1, with stronger phenotypes. Cotyledons are fused. Some leaf pairs are fused too. Most flowers have a single petal (the ventral petal), sometimes more.
ML12450anbhlh1-1/boo14
M. lewisii
flower, Anthocyanin pigmentationMutation in the ANbHLH1 gene, encoding an indispensable component of the anthocyanin-activating MYB-bHLH-WD40 complex. Anthocyanin production is abolished in the petal lobe and stem base and much reduced in the nectar guides, but not affected in other tissues.
Reference: Yuan et al. 2014. New Phytologist. 204: 1013–1027.
ML14257act1-D
M. lewisii
whole plant, Corolla tubeA semi-dominant mutation in the ACTIN1 gene, causing reduced width of lateral organs but no effect on length.
Reference: Ding et al. 2017. New Phytologist. 213: 1936-1944.
ML20169yaoming
M. lewisii
whole plantA dominant mutant with much taller stem
ML20400short tube1
M. lewisii
flower, Corolla tubeShorter corolla tube, but normal corolla lobes.
MV00025mvrcp2-1
M. verbenaceus
flowerMutation in RCP2, encoding a tetratricopeptide repeat (TPR) protein that regulates carotenoid biosynthesis and chromoplast development. Carotenoid pigments in the corolla are almost entirely gone, giving the flower a purple hue.
Reference: Stanley et al. 2020. Plant Cell 32: 1536–1555.
McCIMcCI
M. cardinalis
flower, Anthocyanin pigmentationA natural mutant on the southern end of the species range (Cedros Island, Baja California, Mexico) with the PELAN gene down-regulated, most likely due to cis-element mutation(s) at PELAN.
Reference: Yuan et al. 2014. New Phytologist. 204: 1013–1027.
