The evolutionary ecology of clonally propagated domesticated plants
New Phytologist, 2010Summary While seed‐propagated crops have contributed many evolutionary insights, evolutionary biologists have often neglected clonally propagated crops. We argue that widespread notions about their evolution under domestication are oversimplified, and that they offer rich material for evolutionary studies.

Ever since Knudson [3] developed a nonsymbiotic in vitro culture method for germination of orchid seeds, tissue (in vitro) culture has played an important and highly significant role in the cultivation, propagation, breeding and preservation of orchid species and hybrids.

Clonal Propagation of Primate Offspring by Embryo Splitting
Science, 2000Primates that are identical in both nuclear and cytoplasmic components have not been produced by current cloning strategies, yet such identicals represent the ideal model for investigations of human diseases. Here, genetically identical nonhuman embryos were produced as twin and larger sets by separation and reaggregation of blastomeres of cleavage ...

Clonal propagation of papaya in vitro
Plant Cell, Tissue and Organ Culture, 1988A procedure for the rapid tissue culture propagation of papaya is being developed. Tissue culture methods using apices of nursery and orchard trees of Carica papaya cv. “Sunrise Solo” were evaluated. The explants were established in a modified Murashige and Tucker (1969) basal medium with half-strength inorganic salts, 0.5mgl-1 6-benzylaminopurine (BA)

Fruit tree species are generally heterogenous and elite selections have been usually propagated vegetatively to maintain their genetic makeup and superior characteristics. With the exception of species such as Betula, Populus and Prunus, regeneration of woody taxa in cell and tissue cultures has been rather elusive despite several years of research ...

Palm products, historically and currently, are important sources of economic revenues for sub-tropical and tropical countries (e.g. palm oil accounts for 15% of the world’s total vegetable oil) [20]. The only means of vegetative propagation in palms, being monocotyledons, is restricted to vegetative lateral bud outgrowths (offshoots) which are produced

Clonal and sexual propagation in Botrytis elliptica
Mycological Research, 2001Genetic variation was found between isolates of Botrytis elliptica from the USA and Taiwan based on 22 polymorphic markers from five RAPD primers. Among these 69 isolates, there were 43 different genotypes. One clonal genotype was found spanning Oregon and Washington, USA, and in a population from Hsinshe, Taiwan, clonal genotypes were frequent ...

Rapid clonal propagation of Dioscorea zingiberensis
Plant Cell, Tissue and Organ Culture, 2003A protocol was developed for rapid in vitro propagation of Dioscorea zingiberensis Wright using stems as explants. MS medium with the macroelements at half strength and supplemented with 20.0 g l−1 sucrose and 8.0 g l−1 agar was used as basal medium.

Recalcitrance in clonal propagation, in particular of conifers
Plant Cell, Tissue and Organ Culture (PCTOC), 2009Despite major advances in forest biotechnology, clonal regeneration by somatic embryogenesis or organogenesis is still difficult for many woody species and is often limited to the use of juvenile explants. Adventitious regeneration of plants from gymnosperms older than zygotic embryos, and frequently even from highly immature zygotic embryos, is often ...

Clonal propagation of Callistemon by tissue culture techniques
Plant Cell Reports, 1982Callus development in Callistemon viminalis was readily achieved when axillary buds derived from nodal tissue were placed in a medium containing macro- and micro-nutrients, sucrose (0.06 M), inositol (300 μM), nicotinic acid (20 μM), pyridoxine hydrochloride (3 μM), thiamine hydrochloride (2 μM), riboflavin (10 μM), cytokinins (5 μM) and auxins (0.1 μM)
