Mecanismos de resistencia en el sitio de acción y fuera del sitio de acción (TSR y NTSR) en gramíneas resistentes a glifosato

, 2021
El control de malas hierbas mediante el uso de herbicidas es una de las principales herramientas utilizadas en la agronomía con la finalidad de poder subsistir y alcanzar mayores niveles de producción agrícola. No obstante, el uso repetido de los herbicidas ha ocasionado que múltiples especies hayan evolucionado como resistentes a estos productos.

Degradation and metabolism of fenoxaprop-P-ethyl in sensitive and resistant populations of Alopecurus myosuroides

Julius-Kühn-Archiv, 2014
Blackgrass (Alopecurus myosuroides) is one of the most economically important weeds in Europe. Because of the development and distribution of herbicide resistant populations the control of this weed has become a serious challenge in agriculture.

The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions

Crop Journal, 2014
For smooth and wide application of conservation agriculture (CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA

A test for whether or not Voyager 1 has crossed the heliopause [PDF]

, 2014
The Voyager 1 spacecraft is currently in the vicinity of the heliopause, which separates the heliosphere from the local interstellar medium. There has been a precipitous decrease in particles accelerated in the heliosphere and a substantial increase in

Occurrence and Mechanisms Conferring Multiple Resistance to ALS-Inhibiting and Auxins Mimics Herbicides in Papaver rhoeas from Tunisia

Agronomy
Herbicide-resistant corn poppy (Papaver rhoeas L.) is one of the most important broadleaved weeds and the number of resistant cases is still growing. The aims of this study were to confirm the resistance of P.

Carfentrazone-ethyl resistance in an Amaranthus tuberculatus population is not mediated by amino acid alterations in the PPO2 protein.

PLoS ONE, 2019
To date, the only known mechanism conferring protoporphyrinogen IX oxidase (PPO)-inhibitor resistance in waterhemp (Amaranthus tuberculatus) is a glycine deletion in PPO2 (ΔG210), which results in cross-resistance to foliar PPO-inhibiting herbicides ...

Fitness of ALS-Inhibitors Herbicide Resistant Population of Loose Silky Bentgrass (Apera spica-venti)

Frontiers in Plant Science, 2017
Herbicide resistance is an example of plant evolution caused by an increased reliance on herbicides with few sites of action to manage weed populations.

Non-target site-based resistance to tribenuron-methyl and essential involved genes in Myosoton aquaticum (L.)

BMC Plant Biology, 2018
Background Water chickweed (Myosoton aquaticum (L.)) is a dicot broadleaf weed that is widespread in winter fields in China, and has evolved serious resistance to acetolactate synthase (ALS) inhibiting herbicides. Results We identified a M.
