2. Effect of picloram, additives and plant growth regulators on somatic embryogenesis of Phyla nodiflora (L.) Greene
The present study describes the plant regeneration via somatic embryogenesis in suspension culture derived from the leaf and stem explants of Phyla nodiflora. The medium type, plant growth regulators, complex extract (coconut milk and malt extract) and anti-oxidant (activated charcoal, ascorbic acid, Polyvinylpyrrolidone and citric acid) markedly influenced

4. BIOCHEMICAL AND PHYSIOLOGICAL RESPONSES OF Cucumis sativus AND Avena sativa TO EXCESS ALUMINUM STRESS. / RESPOSTAS BIOQUÍMICAS E FISIOLÓGICAS DE Cucumis sativus E Avena sativa AO ESTRESSE CAUSADO POR ALUMÍNIO
Aluminum (Al) is the most abundant metal in the Earth s crust, affecting growth and development of plants. The aim of this study was to investigate the effects of Al on seedlings of cucumber (Cucumis sativus L.) and oat (Avena sativa L) through the analysis of biochemical and physiological parameters. Three different genotypes of oat seedlings were studied,

5. Changes in growth and photosynthetic capacity of cucumber seedlings in response to nitrate stress
The effects of three nitrate levels - 14(CK), 56(T-1), and 140 mmol L-1 (T-2) - on growth and photosynthetic capacity of cucumber (Cucumis sativus L. cv. Xintaimici) seedlings grown in hydroponic culture were investigated. The results showed that at 12 d after treatment plant height, stem diameter, leaf area, and leaf number of cucumber seedlings were stimul

6. Estudo morfofisiologico do desenvolvimento das especies Galianthe grandifolia E. L. Cabral (Rubiaceae) e Campulocliniun chlorolepis Baker (Asteraceae) submetidas a diferentes concentrações de cadmio / Morphophysiological development of Galianthe grandifolia E. L. Cabral (Rubiaceae) and Campulocliniun chlorolepis Baker (Asteraceae) subjected to different cadmium concentrations
The accumulation of toxic metals in the soil brings forth great environmental damages, especially cadmium, due to its high toxicity and cumulative effects on the organisms in general. There are a few studies regarding heavy metals and Cerrado native species. The aim of this work was to assess the behavior of two Cerrado species cultivated in the greenhouse:

7. Análise da atividade linfoproliferativa de células esplênicas murinas frente a extrato de seis plantas medicinais da flora catarinense / Analysis of the citotoxic and lymphoproliferative activity of methanolic exctracts of medicinal plants on murine spleen cells
Some compounds have been used as immunomodulatory agents, enabling the function of the immune system to be modified, stimulating or suppressing it. There has been increasing interest in the study of therapeutic activities of plant extracts in recent years, including their immunomodulatory activity. The aim of the present work is to identify and evaluate the

8. Reatividade antigênica entre Phytomonas serpens E Trypanosoma cruzi : uma análise proteômica
The genus Phytomonas comprises trypanosomatids that can parasitize a broad range of plant species and are responsible for important phytopatologies resulting in great economic losses. Phytomonas serpens, a trypanosomatid that parasitize tomato, is transmitted among plants by phytofagous insects. Previous studies in our laboratory showed that P. serpens prese

9. White Light Requirements for Stimulation of Plant Growth by Malformin 1
Over a 3-day period, the minimum white fluorescent light intensity required for malformin-induced growth stimulation of etiolated and green cuttings of Phaseolus aureus was approximately 2.6 × 103 and 0.4 × 103 ergs/cm2 · sec, respectively. High light intensities were unable to inhibit the ability of malformin to stimulate growth. Over 3 days, the minimum

10. Growth and N Allocation in Rice Plants under CO2 Enrichment.
The effects of CO2 enrichment on growth and N allocation of rice (Oryza sativa L.) were examined. The plants were grown hydroponically in growth chambers with a 14-h photoperiod (1000 [mu]mol quanta m-2 s-1) and a day/night temperature of 25/20[deg]C. From the 28th to 70th d after germination, the plants were exposed to two CO2 partial pressures, namely 36 a

11. Wind-induced plant motion immediately increases cytosolic calcium.
Wind is one of the most unusual and more dramatic of the environmental signals to modify plant development. Wind-stimulated crops are also known to experience considerable reductions in growth and subsequent yield. There is at present no experimental data to suggest how wind signals are perceived and transduced by plant cells. We have genetically transformed

12. The Fast and Transient Transcriptional Network of Gravity and Mechanical Stimulation in the Arabidopsis Root Apex1[w]
Plant root growth is affected by both gravity and mechanical stimulation (Massa GD, Gilroy S [2003] Plant J 33: 435–445). A coordinated response to both stimuli requires specific and common elements. To delineate the transcriptional response mechanisms, we carried out whole-genome microarray analysis of Arabidopsis root apices after gravity stimulation (re
