MOSAICISM. "A fundamental principle of biology is that the DNA blueprint of a multicellular organism is identical among cells within the organism. The term mosaicism describes a violation of this principle that arises when specific cells within a developing organism mutate to develop two or more cell populations with distinct genotypes." https://lnkd.in/dtPwxTq View in LinkedIn

DISTINCTION. "Mosaicism stands in contrast to chimerism, the phenomenon of an individual being composed of the products of two or more fertilization events." https://lnkd.in/dtPwxTq View in LinkedIn

SOMATIC MOSAICS. "Nearly all of the genetic material among cells within an organism is identical. However, single nucleotide variants (SNVs), indels, copy number variants (CNVs), and other structural variants (SVs) continually accumulate as cells divide during development. This process results in an organism composed of countless cells, each with its own unique personal genome. Thus, every human is undoubtedly mosaic." https://lnkd.in/dtPwxTq View in LinkedIn

MUTABLE GENES. Most genes are relatively stable and mutate at low frequencies, but some mutate faster, called mutable genes. These give rise to genetic mosaics containing mutated and non-mutated tissues, typically in somatic tissues. https://lnkd.in/dtPwxTq View in LinkedIn

SOMATIC MUTATION INHERITANCE. "In contrast with the situation in higher animals, somatic mutations in higher plants can enter the germline and be transmitted the progeny. This is due to two unique features of their development: i) unilimited growth and cell totipotency." https://lnkd.in/dcpj9qm View in LinkedIn

150 MORNING GLORY MUTANTS PRESERVED. "The National Institute for Basic Biology (NIBB) is a sub-center of the National BioResource Project (NBRP) for work on Morning Glories. Our group works with the core institute at Kyushu University to gather, preserve, and distribute mutant lines for flower pigmentation and various DNA clones." But thousands have been lost. https://lnkd.in/d4mmCAr View in LinkedIn

MORNING GLORY DNA LIBRARY. "We used a cDNA library from seedlings, and 3 cDNA libraries from flowers and buds of wild-type...to obtain EST sequences, and are now preserving over 60,000 EST clones. The DDBJ and other public database accession numbers for the 25,899 EST sequences obtained from flower and bud full-length cDNA. We are preserving 55,296 BAC clones." https://lnkd.in/d4mmCAr View in LinkedIn

VARIANTS ARE POLLINATED DIFFERENTLY. "Populations of the common morning glory in the southeastern US are characterized by a striking diversity of flower color polymorphisms. This diversity is probably a consequence of horticultural escapes from cultivation in the 18th and 19th centuries...some color phenotypes are selected by virtue of their differential attraction to insect pollinators." https://lnkd.in/d2DeZMC View in LinkedIn

COINCIDENT with the passion for horticulture in the Edo Period in Japan, the Europeans, in particular, the Dutch, had an obsession with the tulip. Given the close relationship of the the Dutch East India Company in Japan and its very active diffusion of Lilies and other plants from Japan to Europe, the possibility exists for at least a second line of bilateral horticultural diffusion between Japan and Holland.
