    Chlorophyll biosynthesis from glutamate or 5-aminolevulinate in intact Euglena chloroplasts (1985)
    Springer
    Planta 165 (1985), S. 12-22 
    Details
    ISSN: 1432-2048
    Keywords: 5-Aminolevulinic acid ; Chlorophyll synthesis ; Chloroplast ; Euglena ; Glutamic acid ; Protein synthesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Chloroplasts observed, by electron microscopy, to be intact and uncontaminated, with high rates of light-dependent protein synthesis and CO2 fixation were isolated from cells grown on low-vitamin-B12 medium in the light or from cells grown in the same medium in the dark and then exposed to light for 36 h. Both types of chloroplasts were active but less variability was encountered with developing chloroplasts from 36-h cells. The 36-h chloroplasts showed good light-dependent incorporation of 5-amino-levulinic acid (ALA) or l-glutamic acid into chlorophyll (Chl) a which was linear for approx. 1 h. The specific activity of the Chl a remained the same after conversion to pheophytin a, methylpheophorbide a or pyromethylpheophorbide a and rechromatography, indicating that the label was in the tetrapyrrole. Incorporation of ALA was inhibited by levulinic acid, and by chloramphenicol and other inhibitors of translation of 70S-type chloroplast ribosomes at concentrations which did not appreciably inhibit photosynthesis but which blocked plastid protein synthesis nearly completely. Cycloheximide, an inhibitor of translation on 87S cytoplasmic ribosomes of Euglena, was without effect. The 70S inhibitors did not block uptake of labeled ALA. Although labeled glycine was taken up by the plastids, no incorporation into Chl a was observed. Thus the developing chloroplasts appear to contain all of the enzymatic machinery necessary to convert glutamic acid to Chl via the C5 pathway of ALA formation but the Shemin pathway from succinyl coenzyme A and glycine to ALA appears to be absent. The requirement for plastid protein synthesis concomitant with Chl synthesis indicates a regulatory interaction and also indicates that at least one protein influencing Chl synthesis is synthesized on 70S-type plastid ribosomes and is subject to metabolic turnover.

    In vitro culture of Foeniculum vulgare: callus characteristics in relation to morphogenesis (1996)

    Notes: Abstract Callus induction and morphogenic response of several fennel populations were determined by genotype and hormonal treatment. 100% callus formation occurred only in the Francia Pernod population under the action of 2, 4-dichlorophenoxyacetic acid or α-naphthaleneacetic acid and kinetin. Only this last hormonal treatment induced shoot regeneration. Plant regeneration was observed especially in Francia Pernod population. Ths calluses grown in presence of 2,4-dichlorophenoxyacetic acid or α-naphthaleneacetic acid plus kinetin, showed considerable differences at cytological and histological level which were correlated to their different morphogenic capability.

    In vitro culture of species and varieties of four Amaranthus L. species (1992)
    Springer
    Euphytica 62 (1992), S. 181-186 
    Details
    ISSN: 1573-5060
    Keywords: Amaranthus spp. ; callus ; organogenesis ; species ; varieties ; amaranthus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Callus induction, callus growth and organogenetic processes were investigated in hypocotyl and stem cultures of four species of Amaranthus each of which comprised several varieties. Callus formation occurred in almost all the varieties in 100% of explants. The combinations of naphtaleneacetic acid plus benzylaminopurine or 2,4-dichlorophenoxyacetic acid plus Kinetin were very effective in causing callus formation; the results for callus growth in presence of the same growth regulator combinations revealed in some cases significant differences among the varieties. As far organogenesis-based on a few varieties-only A. caudatus and A. hypochondriacus responded well forming shoots from callus when cultured in presence of indoleacetic acid plus Kinetin and/or indoleacetic acid plus benzylaminopurine. Root regeneration was also observed in several varieties. Complete plantlets were obtained from rooted shoots. The results are discussed in relation to hormonal effect and the genotype importance.

    Notes: Summary Variation in the capacity to regenerate shoots and morphogenetic potential were investigated by cyclic culture and regeneration of Nicotiana tabacum var. BEL W3. Explants were excised from different shoots formed by the same callus line. Differences in the organogenetic in vitro response among regenerated plantlets was observed in two subsequent regenerate ‘generations’. A progressive decrease of the regenerative capacity was observed across callus line ‘generations’.

    Response of shape in vitro cultures of shape Nicotiana tabacum L. to copper stress and selection of plants from Cu-tolerant callus (1998)
    Springer
    Plant cell, tissue and organ culture 53 (1998), S. 161-169

    ISSN: 1573-5044
    Keywords: callus ; copper toxicity ; N. tabacum ; plant regeneration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In Nicotiana tabacum L. var. BEL W3 copper (Cu) at concentrations higher than 50 μM significantly inhibited callus growth and shoot regeneration. After 5–6 months of culture only a few morphogenic callus lines survived in the presence of 100 μM Cu. These calluses showed the capacity to grow and regenerate shoots through successive subcultures on medium containing 100 μM Cu. The 100 μM Cu-tolerant shoots, in comparison to regenerated control shoots, formed roots only when cultured in the presence of 100 μM Cu. From five independent Cu-tolerant callus lines in a culture period of 4–5 months more than 50 plants (defined ‘tolerant’) able to grow in presence of 100 μM Cu were obtained. These plants showed normal xylem tissue formation while control regenerated plants growing in normal Cu MS content (0.1 μM) had few xylem elements in the central cylinder. No difference as far chlorophyll content and chloroplast structure was found among Cu-tolerant and control plants. In Cu-tolerant plants, dry matter production was higher than in controls, particularly in roots.
