When African violet leaf explants are cultured in vitro, buds and shoots develop directly from the upper leaf surfaces. Three developmentally different African violet chimeras were cultured, and in each case adventitious shoots that developed into plants had the parent chimera pattern. A multicellular origin of the adventitious buds accounts for these results. 
SOMATIC EMBRYOGENESIS AND ITS CONSEQUENCES IN THE GRAMINEAE
There are 2 principal pathways of plant regeneration in tissue cultures: organogenesis (shoot morphogenesis) and somatic embryogenesis. Organogenesis is accomplished by the development of axillaryExpand
ORIGIN OF ADVENTITIOUS SHOOTS REGENERATED FROM CULTURED TOBACCO LEAF TISSUE
TLDR
The histogenic composition of plants regenerated from leaf discs of periclinal chimeras indicated that any cell layer in a leaf can be the ultimate source of shoots, and that shoots can be multicellular in origin. Expand
Induction and origin of adventitious roots from chimeras of Brassica juncea and Brassica oleracea
TLDR
It is demonstrated that replacing the histogenic LI layer (the outermost apical cell layer) with a different genotype might improve adventitious root induction capability of these vegetative tissues due to likely synergistic effects between LI and the other two histogenic layers, LII and LIII.

In Vitro Propagation for Commercial Production of Ornamentals
TLDR
Using cell culture techniques, it is possible to rapidly produce large numbers of identical plants, and the exercises will provide experience in the stages of in vitro micropropagation. Expand
Induction and origin of adventitious shoots from chimeras of Brassica juncea and Brassica oleracea
TLDR
The chimeras between tuber mustard and red cabbage were artificially synthesized and the origin of the adventitious shoots varied with the site of origin on the donor plant, and could be multicellular and multihistogenic. Expand
Histology and stereological analysis of shoot formation in leaf callus of Saintpaulia ionantha Wendl, (African violet)
TLDR
Stereological analysis of the histological events indicated that there was a progressive decrease in the starch content of leaf segments which callused and later differentiated into shoots from the first day of culture to day 24. Expand
Chlorophyll-deficient cell lines which are genetically uncharacterized can be inappropriate for use as phenotypic markers in developmental studies
TLDR
Results demonstrate that when determining morphogenic potential, direct comparisons between in vitro and in vivo systems may not be valid, and demonstrate that because genetically different albino cell layers can differ in their morphogenic response, utilizing a series of periclinal chimeras is useful only if the series is composed of the same two genotypes.

ESTABLISHMENT OF CALLUS CULTURE WITH HIGH PLANT REGENERATION ABILITY FROM LEAF SEGMENTS OF Lysionotus paucifLorus MAxIM.
Calli were induced from leaves of Lysionotus pauciflorus native to Yunnan, China, on gellan gum-solidified MS medium containing 2 mu mol 1(-1) 2,4-D. They showed 4 times proliferation in liquidExpand
Single cell origin of adventitious buds
TLDR
The experimental results of these authors can be interpreted differently and may therefore support as well the opposite standpoint that the adventitious buds are (ultimately) of single-cell origin. Expand
Histogen Layers Contributing to Adventitious Bud Formation Are Determined by their Cell Division Activities
TLDR
Periclinal chimeral cultivar capable of propagation with adventitious shoots of Saintpaulia can be divided into two types, and the possibility was shown that cells in the L2 layer could form shoots by involving cells of the L1 layer with a low division activity. Expand
