... layer. Mature meristem anatomy is therefore asymmetrical in the dorsoventral axis, which is reflected by the domain-specific protein localisation of Class III and Class IV Homeodomain-Leucine-Zippers (MpC3HDZ and MpC4HDZ), and by the promoter activity of Mp YUCCA2 . The dorsoventral asymmetry...

...Jennifer M. Nelson; Barbara Lane; Michael Freeling Maize leaves are initiated from the shoot apex with an inherent leaf dorsoventral polarity; the leaf surface closest to the meristem is the adaxial (upper, dorsal) surface whereas the opposite leaf surface is the abaxial (lower, ventral) surface...

...Richard Waites; Andrew Hudson In angiosperms, individual lateral organs and whole flowers may develop asymmetrically along their dorsoventral axes. Dorsoventral asymmetry of Antirrhinum leaves requires activity of the Phantastica gene and other factors acting redundantly with it. We describe...

...Neil A. McHale; Michael Marcotrigiano ABSTRACT The role of LAM1 in dorsoventrality and lateral growth of the leaf blade was investigated in the ‘bladeless’ lam1 mutant of Nicotiana sylvestris and in periclinal chimeras with lam1 and wild-type ( N. glauca ) cell layers. Mutant lam1 primordia show...

...Richard Waites; Andrew Hudson ABSTRACT To understand better the mechanisms that lead to dorsoventrality in the lateral organs of plants, mutants at the phantastica ( phan ) locus of Antirrhinum majus have been identified and characterised. The leaves, bracts and petal lobes of phan mutants show...
