Cadmium (Cd) was measured in bulk exports of Canada Western Amber Durum collected from 1992-1993 to 2019-2020 shipping years. Cd concentrations decreased by more than a factor of two over this period, from the highest annual median concentration of 0.160 mg/kg in 2003-2004 to the most recent annual median of 0.070 mg/kg for 2019-2020. Over the same time period there was no trend in Cd concentrations in bulk exports of Canada Western Red Spring wheat. The decrease in durum Cd concentrations was correlated with the decrease in production of high Cd accumulating cultivars, demonstrating the success of the Canadian breeding programme at developing low Cd accumulating cultivars, the registration system and producer support in reducing the Cd content of Canada Western Amber Durum.

Soil Cadmium (Cd) contamination is a worldwide problem with negative impacts on human health. Cultivating the Cd-Pollution Safety Cultivar (Cd-PSC) with lower Cd accumulation in edible parts of plants is an environmentally friendly approach to ensure food security with wide application prospects. Specialized mechanisms have been addressed for Cd accumulation in crops.

Chunhua loquat is a novel cultivar that effectively avoids frost damage. However, the quality characteristics of loquats are limited, and the effects of forchlorfenuron application on loquat fruit quality and bioactive substance accumulation remain unclear. In this study, forchlorfenuron was applied at concentrations of 0 (control), 10, 20, 30, and 40 mg/L to the fruit at 24 and 38 days after bloom.

The gene GAD1 encodes a glutamate decarboxylase, which is a rate-limiting enzyme for the biosynthesis of endogenous γ-aminobutyrate acid (GABA), but a potential role of GAD1 in regulating cadmium (Cd) tolerance needs to be further elucidated in plants. The objective of this study was to investigate Cd tolerance of creeping bentgrass (Agrostis stolonifera) and transgenic yeast (Saccharomyces cerevisiae) or Arabidopsis thaliana overexpressing AsGAD1. The Cd-tolerant creeping bentgrass cultivar LOFTSL-93 accumulated more endogenous GABA in relation to a significant upregulation of AsGAD1 in leaf and root than the Cd-sensitive W66569 in response to Cd stress.

Understanding cadmium (Cd) pathways in cacao trees is critical for developing Cd mitigation strategies. This study investigates whether Cd uptake and translocation mechanisms differ between a low and a high Cd-accumulating cacao cultivar. We sampled three replicate trees of each cultivar, and a grafted cultivar that shared the same scion as the low Cd accumulator but had a different rootstock.
