Caracterización de seis genotipo de amaranto (Amaranthus hypochondriacus L.) mediante los patrones de germinación de la semilla expuesta a herbicidas, ácido salicílico y compuestos análogos, sulfato de cobre y carencia de hierro Colegio de Postgraduados
Barrales Cureño, Hebert Jair.
En México, existen algunas variedades seleccionadas de amaranto (A. hypochondriacus) para las zonas templadas como la Línea 1, Mercado, Nepal, Azteca y Mexicano, así como algunas razas criollas como la Tulyehualco y la Mixteca, que por sus características agronómicas y potencial de rendimiento son de las más importantes. El aprovechamiento del amaranto es integral por utilizarse el grano y la planta como verdura y forraje. Las variedades de amaranto Línea 1, Mercado, Nepal, Tulyehualco, Criolla Tulyehualco y Criolla Mixteca fueron caracterizadas para diferenciar a cada una de estas variedades de las demás de acuerdo a características físicas: peso de 100 semillas y patrón de imbibición; así como características fisiológicas de la semilla: cinética y...

Characterization of Pseudomonas bacteria of Piper tuberculatum regarding the production of potentially bio-stimulating compounds for plant growth Acta Amazonica
OLIVEIRA,Danyllo Amaral de; FERREIRA,Solange da Cunha; CARRERA,Daiany Larissa Ribeiro; SERRÃO,Cleyson Pantoja; CALLEGARI,Daihany Moraes; BARROS,Nicolle Louise Ferreira; COELHO,Francinilson Meireles; SOUZA,Cláudia Regina Batista de.
ABSTRACT Despite advances in the identification and characterization of endophytic bacteria in various plant species worldwide, little is known about such microorganisms in plants from the Amazon region. Previous studies reported that Piper tuberculatum endophytic Pseudomonas (isolates Pt12 and Pt13, identified as Pseudomonas putida and Pseudomonas sp., respectively) were able to inhibit the in vitro growth of Fusarium solani f. sp. piperis, which causes root rot in black pepper (Piper nigrum), and that Pt13 promoted the growth of P. nigrum. Therefore, the aim here was to characterize these bacteria regarding their ability to produce plant growth-promoting substances [siderophores, indol acetic acid (IAA) and soluble phosphate]. Chrome azurol S assays were...

Characterization of streptomycetes with potential to promote plant growth and biocontrol Scientia Agricola
Sousa,Carla da Silva; Soares,Ana Cristina Fermino; Garrido,Marlon da Silva.
Studies with streptomycetes in biocontrol programs and plant growth promotion are presented as technological alternatives for environmental sustainable production. This work has the objective of characterizing six isolates of streptomycetes aiming the production of extracellular enzymes, indole acetic acid, capacity for phosphate solubilization, root colonization and growth under different pH and salinity levels. For detection of enzyme activity the isolates were grown in culture media with the enzyme substrates as sole carbon source. The root colonization assay was performed on tomato seedlings grown on 0.6% water-agar medium. Growth under different pH and salinity levels was evaluated in AGS medium with 1%, 1.5%, 2%, 2.5%, and 3% NaCl, and pH levels...

Endophytic Bacillus strains enhance pearl millet growth and nutrient uptake under low-P BJM
Ribeiro,Vitória Palhares; Marriel,Ivanildo Evódio; Sousa,Sylvia Morais de; Lana,Ubiraci Gomes de Paula; Mattos,Bianca Braz; Oliveira,Christiane Abreu de; Gomes,Eliane Aparecida.
Abstract Bacterial endophytes are considered to have a beneficial effect on host plants, improving their growth by different mechanisms. The objective of this study was to investigate the capacity of four endophytic Bacillus strains to solubilize iron phosphate (Fe-P), produce siderophores and indole-acetic acid (IAA) in vitro, and to evaluate their plant growth promotion ability in greenhouse conditions by inoculation into pearl millet cultivated in a P-deficient soils without P fertilization, with Araxá rock phosphate or soluble triple superphosphate. All strains solubilized Fe-P and three of them produced carboxylate-type siderophores and high levels of IAA in the presence of tryptophan. Positive effect of inoculation of some of these strains on shoot...

Isolation and characterization of two plant growth-promoting bacteria from the rhizoplane of a legume (Lupinus albescens) in sandy soil Rev. Bras. Ciênc. Solo
Giongo,Adriana; Beneduzi,Anelise; Ambrosini,Adriana; Vargas,Luciano Kayser; Stroschein,Marcos Roberto; Eltz,Flávio Luiz; Bodanese-Zanettini,Maria Helena; Passaglia,Luciane Maria Pereira.
Two bacterial strains that amplified part of the nifH gene, RP1p and RP2p, belonging to the genus Enterobacter and Serratia, were isolated from the rhizoplane of Lupinus albescens. These bacteria are Gram-negative, rod-shaped, motile, facultative anaerobic, and fast-growing; the colonies reach diameters of 3-4 mm within 24 h of incubation at 28 ºC. The bacteria were also able to grow at temperatures as high as 40 ºC, in the presence of high (2-3 % w/v) NaCl concentrations and pH 4 -10. Strain RP1p was able to utilize 10 of 14 C sources, while RP2p utilized nine. The isolates produced siderophores and indolic compounds, but none of them was able to solubilize phosphate. Inoculation of L. albescens with RP1p and RP2p strains resulted in a significant...

Abastract: The interaction between Metarhizium spp. and plant roots may induce host plant growth and help control below- and above-ground pests and diseases. We conducted in vivo and in vitro bioassays using native Brazilian isolates of Metarhizium robertsii (ESALQ 1635), M. humberi (ESALQ 1638), and M. anisopliae (ESALQ 1669) to better understand the possible mechanisms related to plant growth promotion traits and colonization of the root system in the model pot-grown tomato (Solanum lycopersicum L.) miniature cultivar ?Micro-Tom.? In vivo trials revealed that M. robertsii (ESALQ 1635) or M. humberi (ESALQ 1638) inoculated in tomato seedlings improved vegetative and reproductive traits. Inoculation with M. robertsii yielded taller plants, longer roots,...

Promotion of iron nutrition and growth on peanut by Paenibacillus illinoisensis and Bacillus sp. strains in calcareous soil BJM
Liu,Di; Yang,Qianqian; Ge,Ke; Hu,Xiuna; Qi,Guozhen; Du,Binghai; Liu,Kai; Ding,Yanqin.
ABSTRACT This study aimed to explore the effects of two siderophore-producing bacterial strains on iron absorption and plant growth of peanut in calcareous soil. Two siderophore-producing bacterial strains, namely, YZ29 and DZ13, isolated from the rhizosphere soil of peanut, were identified as Paenibacillus illinoisensis and Bacillus sp., respectively. In potted experiments, YZ29 and DZ13 enhanced root activity, chlorophyll and active iron content in leaves, total nitrogen, phosphorus and potassium accumulation of plants and increased the quality of peanut kernels and plant biomass over control. In the field trial, the inoculated treatments performed better than the controls, and the pod yields of the three treatments inoculated with YZ29, DZ13, and YZ29 +...
