13. Phytochemical and Morphological Evidences for Shikonin Production by Plant Cell Cultures of Onosma sericeum Willd
ABSTRACT Shoot regeneration, callus growth, and biosynthesis of shikonin in callus cultures of Onosma sericeum were examined. Plant tissue culture was used as an alternative method for increasing the production of shikonin, a secondary metabolite. The isolated cultures were subjected to abiotic factors such as light, plant growth regulators, and nutritional

14. Tissue culture of ornamental cacti
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to i

15. 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

17. Estudos iniciais de caracterização funcional de peroxidases e laccases potencialmente envolvidas no processo de lignificação em cana-de-açúcar / Initial studies on the functional characterization of peroxidases and laccases potentially involved in the lignification process in sugarcane
Lignin is a complex heteropolymer deposited in the secondarily thickened walls of specialized plant cells to provide strength and rigidity for plants to stand upright and hydrophobicity to conducting cells for long-distance water transport. Although lignin is essential for plant growth and development, this phenolic polymer is the major plant cell wall compo

18. Produção de carotenoides em culturas in vitro de Cleome rosea Vahl ex DC (Capparaceae) e avaliação de sua toxicidade e potencial antioxidante / Carotenoid production in vitro cultures of Cleome rosea Vahl ex DC (Capparaceae) and evaluation of toxicity and antioxidant potential.
The production and optimization of plants secondary metabolites with medicinal value have been achieved by using plant tissue culture techniques, which have showed great relevance when considering the conservation status of a species or their occurrence in degraded environments. The present study assessed the production of carotenoids in callus and cell susp

19. Otimização do crescimento e desenvolvimento de teca (Tectona grandis Linn f.) in vitro / Optimization of teak (Tectona grandis Linn f.) growth and development in vitro
O crescente aumento no uso da micropropagação de teca como forma de produção de clones com qualidades genotípicas e fenotípicas selecionadas a partir de árvores de elite, determinou a importância desse método, pois origina plantações com maior qualidade e uniformidade, agregando maior valor ao preço da madeira no mercado. O uso de sementes para a

20. Biologia e comportamento de Sitobion avenae (Hemiptera: Aphididae) em quatro cultivares comerciais de trigo (Triticum aestivum L.) / Biology and behavior of Sitobion avenae (Hemiptera: Aphididae) in four commercial varieties of wheat
The use of resistant wheat cultivars to S. avenae is important for the management of culture due to the potential damage of aphid. In Brazil, however, little is known about the resistance of wheat cultivars to S. avenae. The goal of this work was to assess the behaviour and biology of S. avenae in leaves and ears of four commercial wheat cultivars to verify

22. Plant regeneration from long-term callus culture of aaa-group dessert banana.
The banana plant is one of the most widely cultivated crops in the world. However, banana breeding has been a slow process, due to the low seed set and low germination rates. Selection of useful somaclonal variations and genetic transformation in cells or calluses are promising techniques to accelerate the breeding process. Therefore, callus culture was carr

24. Efficacy of banana plantlet production by micropropagation.
The use of banana (Musa spp.) plant production by tissue culture is increasing throughout the world. However the occurrence of somaclonal variation has been one of the most important problems affecting the commercial value of the plants. A reason for the somaclonal variation can be the time of permanence of the culture in vitro, i.e., the number of subcultur
