1. Evaluation of limonoid production in suspension cell culture of Citrus sinensis
ABSTRACTThe use of cell and plant tissue culture techniques to produce economically important active metabolites has been growing. Among these substances are total limonoid aglycones, which are produced by "pera" orange (Citrus sinensis (L.) Osbeck, Rutaceae) and have received considerable attention because of their anticancer actions. The main objective of

2. Cultura de anteras e partenogênese in situ e in vitro de genótipos de laranja doce (Citrus sinensis Osbeck.) / Anther culture and in vitro and in situ parthenogenesis of sweet orange (Citrus sinensis Osbeck.) genotypes
The production of completely homozygous lines in citrus breeding program is hard, and double-haploid plantlets (completely homozygous lines) can be used to improve these breeding programs. However, many factors are associated with the success of the regeneration of haploid or double-haploid plants. The aim of this study was the induction and regeneration of

3. Biological activity of amides and analogs from Piper species and synthetic analogs / Atividade biológica de amidas e análogos de espécies de Piper e estudos biossintéticos
Six amides were isolated from Piper scutifolium and P. corcovadensis including piperovatine, piperlonguminine, isopiperlonguminine and corcovadine, the new scutifoliamide A and scutifoliamide B and also two aristolactams (piperolactam C and stigmalactam). From P. tuberculatum the amides piplartine and pellitorine and two esters, ethyl (E)-3,4,5-trimethoxycin

5. Análise da expressão de enterolobina em sementes e calos vegetais de Enterolobium contortisiliquum
Cytolytic toxins are produced by a variety of living organisms, particularly bacteria, certain insects, poisonous reptiles and stinging marine invertebrates. Many of these toxins appear to function simply by forming pores in cell membranes, disrupting the permeability barrier and leading eventually to cell death. However, few examples have been studied in pl

6. Induction and selection of Eucalyptus urophylla cell lines resistant to thermic and hydric stresses / Indução e seleção de linhagens celulares de Eucalyptus urophylla para tolerância aos estresses hídrico e térmico
This work aimed to assess a possible relation between hight temperature and improvement in drought tolerance, as well as identify and select Eucalyptus urophylla cell lines under physiological and biochemical aspects. Callus obtained from hypocotyl of Eucalyptus urophylla and cultivated in N7 medium (SIMOLA, 1985) with the addition of 5mg.L-1 of Picloram wer

7. ProduÃÃo de lectina em culturas de tecidos de Bauhinia monandra (calos, raÃzes convencionais e transformadas por Agrobacterium rhizogenes); avaliaÃÃo de extratos das folhas da planta como fonte de compostos antioxidantes e hipoglicemiantes
Lectins, proteins that recognize carbohydrates specifically and reversibly, can be purified by affinity chromatography. The genus Bauhinia (Fabaceae) includes native or introduced species that have been used in the treatment of diabetes. A galactose-specific leaf lectin (BmoLL) has been previously purified from B. monandra and available in milligram quantiti

8. Hormone Autotrophic Growth and Differentiation Identifies Mutant Lines of Arabidopsis with Altered Cytokinin and Auxin Content or Signaling1
We describe mutant tissue lines of Arabidopsis that are able to grow in vitro as callus on hormone-free medium. The 14 lines presented here show different hormone autotrophic differentiation behaviors that can be classified into three categories: (a) forming roots (rooty callus), (b) forming shoots or shoot-like structures (shooty callus), or (c) growing wit

9. Generation of Large Numbers of Independently Transformed Fertile Barley Plants.
A rapid, efficient, and reproducible system to generate large numbers of independently transformed, self-fertile, transgenic barley (Hordeum vulgare L.) plants is described. Immature zygotic embryos, young callus, and microspore-derived embryos were bombarded with a plasmid containing bar and uidA either alone or in combination with another plasmid containin

10. Cycloheximide Resistance in Carrot Culture: A Differentiated Function 1
Cultured carrot cells grow as unorganized callus tissue in medium containing auxin. Upon removal of the auxin from the medium, they grow in an organized manner and differentiate into embryos. In the normal cell line, W001C, the callus growth can be inhibited by cycloheximide, but the embryonic growth cannot. A variant cell line, WCH105, whose callus growth i

11. Altered Glycine Decarboxylation Inhibition in Isonicotinic Acid Hydrazide-Resistant Mutant Callus Lines and in Regenerated Plants and Seed Progeny
Isonicotinic acid hydrazide (INH), an inhibitor of the photorespiratory pathway blocking the conversion of glycine to serine and CO2, has been used as a selective agent to obtain INH-resistant tobacco (Nicotiana tabacum) callus cells. Of 22 cell lines that were INH-resistant, none were different from wild-type cells in their ability to take up [3H]INH or to

12. Accumulation of β-Carboline Alkaloids and Serotonin by Cell Cultures of Peganum harmala L: I. CORRELATION BETWEEN PLANTS AND CELL CULTURES AND INFLUENCE OF MEDIUM CONSTITUENTS
A number of cell cultures of Peganum harmala were initiated to check for a correlation between the harman alkaloid content of seedlings and cell lines derived therefrom. Despite a poor correlation between callus or suspension culture lines and parent plants, the mean alkaloid contents of strains derived from seedlings with higher alkaloid yields were neverth
