Abstract Main conclusion Transgenic Arabidopsis thaliana and Populus alba plants overexpressing the zinc transporter ScZRC1 in shoots exhibit Zn tolerance. Increased Zn concentrations were observed in shoots of P. alba, a species suitable for phytoremediation. Abstract Genetic engineering of plants for phytoremediation is worth to consider if genes leading to heavy metal accumulation and...

Abstract Main conclusion We discovered and identified a series of characteristic substances, including one new polyketide, epicorepoxydon B, of the important pathogenic fungus, Epicoccum sorghinum, of sorghum. The fungal extract and some isolated polyketides are sensitive to a malignant triple-negative breast cancer cell line, MDA-MB-231. Abstract Sorghum (Kaoliang) grain is an important crop...

Abstract Main conclusion This study identified a new bHLHm1 transcription factor MdSAT1 which functioned in mediating tolerance to salt and drought resistance. Abstract Changes in the expression of stress-related genes play crucial roles in response to environmental stress. Basic helix-loop-helix (bHLH) proteins are the largest superfamily of transcription factors and a large number of bHLH...

Abstract Main conclusion Root antioxidant defense, restricted root-to-shoot Cu translocation, altered nutrient partition, and leaf gas exchange adjustments occurred as tolerance mechanisms of soybean plants to increasing soil Cu levels. Abstract The intensive application of copper (Cu) fungicides has been related to the accumulation of this metal in agricultural soils. This study aimed to...

Abstract Main conclusion The presence of Bacillus cereus plays a key role in clubroot suppression and improves plant biomass in pak choi. B. cereus is reported for the first time as a novel biocontrol agent against clubroot. Abstract Plasmodiophora brassicae Woronin causes a devastating infectious disease known as clubroot that is damaging to cruciferous vegetables. This study aimed to isolate...

Abstract Main conclusion Bioinformatic, molecular, and biochemical analysis were performed to get more insight into the regulatory mechanism by which TmHKT1;4-A2 is regulated. Abstract HKT transporters from different plant species have been shown to play important role in plant response to salt. In previous work, TmHKT1;4-A2 gene from Triticum monococcum has been characterized as a major...

Abstract Main conclusion Cadmium-sensitive yeast screening resulted in the isolation of protein translation factor SaeIF1 from the hyperaccumulator Sedum alfredii which has both general and special regulatory roles in controlling cadmium accumulation. Abstract The hyperaccumulator of Sedum alfredii has the extraordinary ability to hyperaccumulate cadmium (Cd) in shoots. To investigate...

Abstract Main conclusion We projected meta-QTL (MQTL) for drought, salinity, cold state, and high metal ion tolerance in rice using a meta-analysis based on high-density consensus maps. In addition, a genome-wide association analysis was used to validate the results of the meta-analysis, and four new chromosome intervals for mining abiotic stress candidate genes were obtained. Abstract Drought...

Abstract Main conclusion Transcriptome and physiological analysis showed that exogenous arginine can delay the ripening process of postharvest strawberry fruit. Abstract Arginine (Arg) plays an important role in the growth and development of plants, but its growth and development regulatory mechanisms in strawberry fruit are unknown. In this study, we found that the content of Arg...

Abstract Main conclusion Cadmium stress induces WDR5a expression to promote NO accumulation to repress root meristem growth via suppressing auxin transport and synthesis in Arabidopsis. Abstract Nitric oxide (NO) synthase (NOS)-like activity plays a vital role in toxic cadmium (Cd)-induced NO production and inhibition of root meristem growth, while factor(s) regulating NOS-like activity...

Abstract Main conclusion Activation of GPX and enhanced NO level play a key role in IBA-mediated enhanced Cd tolerance in young barley roots. Abstract Application of exogenous indole-3-acetic acid (IAA) or an IAA precursor improves the tolerance of plants to heavy metals. However, the physiology of these tolerance mechanisms remains largely unknown. Therefore, we studied the priming effect of...

Abstract Main conclusion This study provides broad insight into the chloroplast genomes of the subfamily Monsteroideae. The identified polymorphic regions may be suitable for designing unique and robust molecular markers for phylogenetic inference. Abstract Monsteroideae is the third largest subfamily (comprises 369 species) and one of the early diverging lineages of the monocot plant family...
