Fitorremediação de solo contaminado com picloram por capim-pé-de-galinha-gigante (Eleusine coracana) Phytoremediation of picloram-contaminated soil by Eleusine coracana [PDF]

Revista Brasileira de Ciência do Solo, 2008
O longo efeito residual do herbicida picloram no solo aumenta o risco de lixiviação e de fitotoxicidade em culturas sucedâneas; sua presença no solo pode ser abreviada com o uso da fitorremediação.

Liming on picloram leaching in dystrophic Red Yellow Latosol

Revista Brasileira de Engenharia Agrícola e Ambiental
The practice of liming may influence the leaching of herbicides in soils, especially those with weak acid character, such as picloram. The study on leaching, preserving soil structure, is an important factor when one intends to understand the dynamics of

A deletion upstream of the degron of AcIAA27 leads to auxinic herbicide resistance in Arctotheca calendula. [PDF]

Pest Manag Sci
An in‐frame deletion was identified in AcIAA27, compared to the susceptible population, which confer resistance to both 2,4‐D and dicamba. Abstract BACKGROUND Two populations of Arctotheca calendula (capeweed) from near Naracoorte, South Australia, were not controlled by 2,4‐D. These populations were investigated for resistance to 2,4‐D and other auxin

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4-D in Sisymbrium orientale. [PDF]

Pest Manag Sci
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

Development of the HTRF assay to evaluate the auxin-induced binding between TIR1 and IAA7. [PDF]

New Phytol
Summary Auxin plays diverse roles in plant growth and development, including sensing environmental changes. Quantifying the interaction between auxin coreceptors provides the molecular basis for cells to sense and adapt to environmental cues. Although several assays are available, a more high‐throughput method is necessary to efficiently evaluate the ...
