Bacillus thuringiensis is a naturally abundant Gram-positive bacterium and a well-known, effective bio-insecticide. Recently, B. thuringiensis has attracted considerable attention as a potential biological control agent for the suppression of plant diseases. In this study, the bacterial wilt disease-suppressing activity of B. thuringiensis was examined in tomato plants. Treatment of tomato root...

Abstract We carried out greenhouse experiment to evaluate the effect of silicon (Si) on growth and mineral nutrition yellow passion fruit (Passiflora edulis) submitted saline stress in a nutritive solution. The comprised completely randomized design 5x4 factorial scheme: five NaCl concentrations (0; 7.5; 15; 30 60 mmol L-1) four SiO2 0.5; 1.0 1.5 with replicates. At end 35 days, we measured ste...

Abstract Plant mechanical failure (lodging) causes significant yield loss for crops such as maize. Understanding this has relied on static measurements of plant biomechanics. In study, digital image correlation techniques are used to capture dynamic motion understand the behaviour maize stalks in presence and absence brace roots, which stem-borne aerial roots known stabilize stalks. The data sh...

The MYC genes are a group of transcription factors containing both bHLH and ZIP motifs that play important roles in the regulation of abscisic acid (ABA)-responsive genes. In the present study, to investigate the roles of MYC genes under NaCl, osmotic and ABA stress conditions, nine MYC genes were cloned from Tamarix hispida. Real-time reverse-transcriptase (RT)-PCR showed that all nine MYC gen...

Magnesium is an essential nutrient for the growth and development of plants. Its deficiency becoming a growing concern in many citrus orchards worldwide, adversely affecting numerous functions plants limiting their productivity quality. Three-year-old orange (Citrus sinensis cv. Newhall) grafted on Swingle citrumelo (C. paradisi Macf. × Poncirus trifoliata L.) rootstock were irrigated 63 days w...

Electrical resistances of roots and stems of hydroponically raised willows (Salix schwerinii) were studied and related to root morphology. Willow cuttings with and without roots were set in a constant electric field (effective voltage of 0.1 V, sine-AC, 128 Hz) in a hydroponic solution. The electrical resistance of different components in the measurement system was measured and analysed in rela...

objectives : stem cell (sc) therapy is a promising technique for tissue regeneration. this study aimed to compare the viability and proliferation ability of periodontal ligament stem cells (pdlscs) isolated from the periodontium of healthy and periodontitis-affected teeth to obtain an autologous, easily accessible source of scs for tissue regeneration in periodontitis patients. materials and me...

Flooding induced several physiological and morphological changes in Fraxinus pennsylvanica seedlings, with stomatal closure among the earliest responses. Subsequent changes included: reduction in dry weight increment of roots, stems, and leaves; formation of hypertrophied lenticels and production of adventitious roots on submerged portions of the stem above the soil line; leaf necrosis; and lea...

ABSTRACT The use of mini-cuttings is an option for obtaining sweet potato propagules excellent quality. objective this research was to evaluate the production and quality roots propagated by in different types trays ages seedlings. Six treatments, resulting from factorial 2x3, were evaluated: two (162 200 cells, with 31 18 mL substrate per cell, respectively) three seedlings (39, 46 53 days aft...
