Aluminum (Al) toxicity and low pH are major factors limiting plant growth in acidic soils. Sensitive to Proton Rhizotoxicity 1 (STOP1) transcription factors respond to these stresses by regulating the expression of multiple Al- or low pH-responsive genes. ZmSTOP1-A, a STOP1-like protein from maize (Zea mays), was localized to the nucleus …
The BCF and TF values of un-inoculated Arabidopsis for Sb were 0.08 and 0.42, respectively; whereas in inoculated plants, the corresponding values were 0.04 and 0.80, respectively, indicating that bacterial colonization had a significant effect on the Sb uptake and distribution in Arabidopsis plants.

Arabidopsis halleri is a well-known zinc (Zn) hyperaccumulator, but its status as a cadmium (Cd) hyperaccumulator is less certain. Here, we investigated whether A. halleri can hyperaccumulate Cd and whether Cd is transported via the Zn pathway.. Growth and Cd and Zn uptake were determined in hydroponic experiments with different Cd …

Plant growth-promoting bacteria (PGPB) are indigenous to the plant rhizosphere and largely affect many events occurring during the plant life cycle, through either a direct or an indirect mechanism such as regulation of hormonal balance, facilitation of nutrients uptake and improvement of stress tolerance. Since drought stress, a …
NIP1;2 is a plasma membrane-localized transporter mediating aluminum uptake, translocation, and tolerance in Arabidopsis April 2017 Proceedings of the National Academy of Sciences 114(19):201618557
Magnesium (Mg) is one of the essential nutrients for all living organisms. Plants acquire Mg from the environment and distribute within their bodies in the ionic form via Mg 2+-permeable transporters.In Arabidopsis, the plasma membrane-localized magnesium transporter MGT6 mediates Mg 2+ uptake under Mg-limited conditions, and …
Abstract. Genome duplication (or polyploidization) has occurred throughout plant evolutionary history and is thought to have driven the adaptive radiation of plants. We found that the cytotype of the root, and not the genotype, determined the majority of heritable natural variation in leaf potassium (K) concentration in Arabidopsis thaliana.

Values represent the size of the ladder step in kilobases. - "Gold uptake and tolerance in Arabidopsis" Figure 5.9 T-DNA inserts within the copt2-1 T3 generation DNA electrophoresis gel showing PCR products from the left border to right flanking sequence. DNA ladder was a 1 kb DNA ladder from NEB.
In addition, exogenous MeJA reduces NO levels in Cd-stressed Arabidopsis root tips. Taken together, our results suggest that Cd-induced JA acts via the JA signaling pathway and its effects on NO levels to positively restrict Cd accumulation and alleviates Cd toxicity in Arabidopsis via suppression of the expression of genes promoting Cd uptake ...
