Azospirillum sp. Promotes root hair development in tomato plants through a mechanism that involves ethylene
(Springer, 2006-06)
Tomato seeds were inoculated with the plant growth–promoting rhizobacteria Azospirillum brasilense FT326, and changes in parameters associated with plant growth were evaluated 15 days after inoculation. Azospirilla were ...
Análisis bioinformático y molecular de la ruta de Triptófano independiente hacia la síntesis de Indol Acético en T. Koningiopsis y T. asperellum
(2018-04-09)
RESUMEN: Las especies de Trichoderma han sido ampliamente estudiadas por su actividad de biocontrol y su habilidad de fungir como promotores de crecimiento vegetal mediante la producción de auxinas como el ácido indol ...
Estudio de la participación del gen YUCCA4 en la regulación del crecimiento y desarrollo de Arabidopsis thaliana
(Universidad Michoacana de San Nicolás de Hidalgo, 2014-02)
Plants integrate diverse environmental stimuli to control their growth and development. These processes are under the control of substances known as phytohormones or plant growth regulators whose action mechanisms have ...
Nitric oxide regulates auxin signaling through s-nitrosylation of the Arabidopsis Transport Inhibitor Response1 auxin receptor
(Wiley, 2012-05)
Previous studies have demonstrated that auxin (indole-3-acetic acid) and nitric oxide (NO) are plant growth regulators that coordinate several plant physiological responses determining root architecture. Nonetheless, the ...
DAO1 catalyzes temporal and tissue-specific oxidative inactivation of auxin in Arabidopsis thaliana
(2016-09-27)
Tight homeostatic regulation of the phytohormone auxin [indole-3-acetic acid (IAA)] is essential to plant growth. Auxin biosynthetic pathways and the processes that inactivate auxin by conjugation to amino acids and sugars ...
Revealing the biotechnological potential of Delftia sp. JD2 by a genomic approach
(AIMS Press, 2016)
Delftia sp. JD2 is a chromium-resistant bacterium that reduces Cr(VI) to Cr(III), accumulates Pb(II), produces the phytohormone indole-3-acetic acid and siderophores, and increases the plant growth performance of rhizobia ...
The Glucose-Related Decrease in Polar Auxin Transport During Ripening and its Possible Role in Grapevine Berry Coloring
(2023)
Auxin is a hormone that delays ripening in part by reducing anthocyanin content and impairing color development. Auxin content declines during the ripening process, whereas sugars accumulate from pre-veraison onwards. The ...
Análisis metabólico y termodinámico in silico para la biosíntesis de ácido 3-indolacético (AIA) a partir de glicerol en Azospirillum brasilense
(Departamento de Procesos y EnergíaUniversidad Nacional de Colombia - Sede Medellín, 2019)
In this work the bioconversion of glycerol to indol acetic acid (IAA) is proposed using Azospirillum brasilense as biocatalyst, a bacteria with a natural capacity to produce IAA. In the beginning, a black box model was ...
Análisis del efecto de oligogalacturónidos (OGs) sobre la ruta de señalización de la proteína TOR en maíz (Zea mays L.)
(Universidad Michoacana de San Nicolás de Hidalgo, 2011-02)
Cell growth (increase in size) is regulated by the TOR signaling pathway, which integrates environmental cues that modulate cell growth. In plants the final organ size is determined by its cell number and their ability to ...
Propiedades y mecanismos de acción de fitoreguladores de defensa y autoinductores bacterianos sobre el desarrollo de la raíz de Arabidopsis thaliana
(Universidad Michoacana de San Nicolás de Hidalgo, 2017-09)
The life cycle of plants is highly modulated by a heterogeneous group of bioactive molecules known as plant growth regulators or phytohormones. Indole-3-acetic acid, jasmonic acid, ethylene, and abscisic acid control ...
