genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (musa acuminata cv. dwarf cavendish (aaa)) were studied using morphological and random amplified polymorphic dna (rapd) markers. out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

Texas snowbells (Styrax platanifolius var. texanus) is one of the most threatened native Texas plants. A preliminary study using DNA fingerprinting (RAPDs) was performed on plants from three natural populations. Almost no genetic variation was found, either within or between these three populations. Implications for conservation are discussed. Phytologia 93(2):198-202 (August 1, 2011)

Segregation for 289 random amplified polymorphic DNA markers (RAPDs) has been determined in 106 F z plants of an interspecific hybrid (H27) between M icro~eris douglasii (strain B14) and M. bigelovii (C94). Multicelluar trichomes ("type D", specific for Microseris) occur on the leaf teeth of early vegetative rosettes of the B 14 parent and on the leaf blades of later rosettes in both parents. T...
