Rabbage
''Brassicoraphanus'' is any intergeneric hybrid between the genera ''Brassica'' (cabbages, etc.) and ''Raphanus'' (radish). The name comes from the combination of the genus names. Both diploid hybrids and allopolyploid hybrids are known and share this name. Early experimental crosses between species of these two genera had been sterile or nearly sterile, but large-scale experiments by Soviet agronomist Georgi Dmitrievich Karpechenko using ''Raphanus sativus'' and ''Brassica oleracea'' were remarkable because some of the plants produced hundreds of seeds. The second generation were allopolyploids, the result of gametes with doubled chromosome numbers. As Karpechenko realized, this process had created a new species, and it could justifiably be called a new genus, and proposed the name ''Raphanobrassica'' for them, but the earlier name ''Brassicoraphanus'' has priority. Plants of this parentage are now known as radicole. Two other fertile forms of ''Brassicoraphanus'' are known by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
