Abstract:
Petiole protoplasts of the sweetpotato [Ipomoea batatas (L.) Lam.] cultivars Red Jewel and Georgia Jet formed cell walls within 24 hours and divided in 2 to 3 days. Pretreating enzyme solutions with activated charcoal increased the viability and division frequency of protoplasts. Culture of protoplast-donor plants in a medium containing STS did not affect plant growth, protoplasm yield, or viability, but did increase the division frequency. Culture of protoplasts for 24 hours in a medium containing DB, a cell wall synthesis inhibitor, or staining of protoplasts with FDA did not significantly a

Abstract:
Several tissue types of Lupinus albus L. were investigated as sources for the isolation of protoplasts. Cotyledons from in vitro seedlings were found to yield the highest number of protoplasts compared with leaves, hypocotyls and roots. A combination of the protoplast isolation enzymes, cellulase and Pectolyase Y23, was capable of releasing the highest number of protoplasts compared with a combination of cellulase and Macerase. Protoplast yield increased with increasing cotyledon age but was accompanied by a progressive decline in protoplast viability. The optimal combination of protoplast yie

Abstract:
The present paper describes a simple and reliable protocol for the successful isolation, purification, culture, and regeneration of diploid cotyledon-derived protoplasts of Brassica napus L. cv. 'Topas'. Various protoplast isolation media, nutrient media, subculture procedures, and protoplast sources were tested under two culture temperatures. Protoplast viability, cell wall regeneration, and cell division were monitored. Single cotyledon-derived protoplasts formed calli in liquid protoplast medium, and when these were subcultured on solid proliferation medium and solid regeneration medium of

Abstract:
Protoplasts from primary leaves of barley (Hordeum vulgare L.) were obtained by enzymatic digestion and fractionated by discontinuous density gradient centrifugation to yield highly enriched fractions of mesophyll and epidermal protoplasts. A characterization of both protoplast types resulted in a clear differentiation of the outer protoplast surfaces. The protoplasts were examined for affinity to various lectins by agglutination tests and by labeling with lectin – fluorescein isothiocyanate conjugates. Both types of protoplasts agglutinated with soybean lectin. Fluorescein isothiocyanate-labe

For protoplast isolation, the best combination of hydrolytic enzymes was cellulysin (1% w/v; Calbiochem) plus macerase (0.5% w/v; Calbiochem), with a 24 hour digestion at 30°C in the dark. Yields reached 7.2 (10)6 protoplasts/g leaf tissue. Protoplast viabilities ranged from 65% to 96%.

Protoplasts are single cells isolated from tissues or organs and are considered a suitable system for cell studies in plants. Embryogenic cells are totipotent stem cells, but their regeneration ability decreases or becomes lost altogether with extension of the culture period. In this study, we isolated and cultured EC-derived protoplasts (EC-pts) from carrots and compared them with non-EC-derived protoplasts (NEC-pts) with respect to their totipotency. The protoplast isolation conditions were optimized, and the EC-pts and NEC-pts were characterized by their cell size and types. Both types of p

Few other woody plants embody the preeminence of temperate woody plants in garden cultivation like the lilacs. In spite of their relationship, the trees lack the diversity of cultivated floral forms observed within the shrub lineages. Typical selection and cross-pollination schemes within the tree lilacs or between trees and shrubs have failed to yield the diversity of colors and fragrances on a tree form.

Abstract:
Root-knot nematodes, Meloidogynespp., are extremely destructive pathogens with a cosmopolitan distribution and a host range that affects most crops. Safety and environmental concerns related to the toxicity of nematicides along with a lack of natural resistance sources threaten most crops in Israel and the U.S. This emphasizes the need to identify genes and signal mechanisms that could provide novel nematode control tactics and resistance breeding targets. The sedentary root-knot nematode (RKN) Meloidogynespp. secrete effectors in a spatial and temporal manner to interfere with and mimic multi

Abstract:
Highly asymmetric somatic hybrid plants were obtained by PEG/DMSO fusion of gamma irradiated (100, 250, 7500 and 1000 Gy) protoplasts of a (KmR-) interspecific hybrid Lycopersicon esculentum x L. pennellii (EP) with protoplasts of eggplant (E). Somatic hybrid calli were selected based on kanamycin resistance and verified by PCR of the NptII gene, RAPD's and Southern's using potato rDNA pTHG2 probes. Flow cytometry indicated all hybrid calli that did not regenerate shoots were 5-9n. Three asymmetric plants regenerated only from callus close to 4n and such calli oly occurred when EP received 100
