Comparative investigations on protoplast culture of some Brazilian and Hungarian sweet pepper cultivars and hybrids

open access: yesInternational Journal of Horticultural Science, 1999
Cotyledon protoplasts were isolated from 16-18-day-old in vitro grown seedlings of 9 Brazilian and 3 Hungarian pepper varieties and hybrids. Large numbers (average 9.59 X 106 protoplasts g 14 fresh weight) of highly viable (average 87.0%) protoplasts ...

Ultrastructural Analysis of Electrofused Protoplasts from Pansy and Wild Viola by Scanning Electron Microscopy

open access: yesPlant Production Science, 1998
Ultrastructural changes during the fusion of the protoplasts isolated from wild viola callus (without chloroplasts) and pansy mesophyll cells (with chloroplasts) were examined by scanning electron microscopy (SEM) and transmission electron microscopy ...

Identification of functional cis-regulatory elements by sequential enrichment from a randomized synthetic DNA library [PDF]

open access: yes, 2013
BACKGROUND: The identification of endogenous cis-regulatory DNA elements (CREs) responsive to endogenous and environmental cues is important for studying gene regulation and for biotechnological applications but is labor and time intensive. Alternatively,

Preparation and Transfection of Populus tomentosa Mesophyll Protoplasts

open access: yesBio-Protocol, 2021
Mesophyll protoplasts freshly isolated from leaves are a useful research system in plants. However, cell walls in woody plants contain more pectin, making mesophyll protoplasts isolation difficult in Populus.

Genome-Wide Identification, Functional Analysis and Expression Profiling of the Aux/IAA Gene Family in Tomato [PDF]

open access: yes, 2012
Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the plant hormone auxin rely on the cooperative action of several components,among

Progress towards sugar beet improvement through somatic hybridization I. Inactivation of nuclei and cytoplasm in donor and recipient protoplasts

open access: yesActa Societatis Botanicorum Poloniae, 2014
The isolation and culture of suspension-derived protoplasts from two sugar beet (Beta vulgaris L.) genotypes are described. Immobilization of protoplasts in agarose resulted in high frequency divisions and microcallus regeneration, with plating ...

Reversion of Streptococcal Protoplasts [PDF]

open access: yesJournal of Bacteriology, 1972
The reversion of protoplasts of Streptococcus faecium was examined by light and scanning electron microscopy. Regularly shaped streptococci emerged from the narrow region of large, oval protoplasts.
