Regulation of Tobacco Acetolactate Synthase Gene Expression [PDF]
Plant Physiology, 1993 Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of isoleucine, leucine, and valine. The previous cloning of two tobacco (Nicotiana tabacum) ALS genes (SurA and SurB) has allowed transcript accumulation from these genes to be monitored. mRNA blot analysis of ALS transcripts showed a message size of 2.2 kb. Quantitation of

Sulfonylurea resistance in Amaranthus hybridus from southern Brazil [PDF]
Revista Ceres, 2022 Amaranthus hybridus is a C4 broadleaf species widely spread across Brazilian agricultural territory. Recently, several herbicide resistance reports have been documented in southern Brazil, including the reports for enolpyruvilshikymate-3-phosphate (EPSPS)

Stable isotope profiles reveal active production of VOCs from human-associated microbes. [PDF]
, 2017 Volatile organic compounds (VOCs) measured from exhaled breath have great promise for the diagnosis of bacterial infections. However, determining human or microbial origin of VOCs detected in breath remains a great challenge.

Characterizing fruit ripening in plantain and Cavendish bananas: A proteomics approach [PDF]
, 2020 The fruit physiology of banana cultivars other than Cavendish is poorly understood. To study the ripening process, samples were taken daily from plantain and Cavendish bananas and the ripening stages were determined. We present data from the green to the

CodY, a pleiotropic regulator, influences multicellular behaviour and efficient production of virulence factors in Bacillus cereus [PDF]
, 2012 In response to nutrient limitation in the environment, the global transcriptional regulator CodY modulates various pathways in low G+C Gram-positive bacteria.

Barnyardgrass shows sensitivity to reduced doses of topramezone at different growth stages [PDF]
, 2019 Using less than the labelled dose of herbicides depends mostly on weed spectrum and growth stage of target weeds. The aim of the greenhouse experiment was to determine the efficacy of recommended (67.2 g a.i. ha-1) and reduced doses (44.8, 33.6, 22.4, 16.

Resistance of Amaranthus retroflexus to acetolactate synthase inhibitor herbicides in Brazil [PDF]
Planta Daninha, 2014 When in competition with cotton, Amaranthus retroflexus can cause high yield losses. Due to the limited availability of selective herbicides registered for post emergence control of this weed, the same herbicides have been used repeated times over the ...

Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]
, 2009 Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.
