TaGSr contributes to low-nitrogen tolerance by optimizing …
Glutamine synthetase (GS) is a key enzyme that assimilates ammonium to form glutamine. However, little is known about the function of TaGSr (Triticum aestivum L. root glutamine synthetase) in nitrogen metabolism in wheat. In this study, we evaluated the effects of ectopic expression of TaGSr from wheat on nitrogen uptake, assimilation, and …

Jasmonic acid alleviates cadmium toxicity in Arabidopsis …
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 ...

ZAT10 plays dual roles in cadmium uptake and detoxification in Arabidopsis
However, the definite function of ZAT10 in Cd tolerance remains uncertain. Here, we demonstrated that ZAT10 negatively regulated Cd uptake and enhanced Cd detoxification in Arabidopsis. The expression of ZAT10 in plants is induced by Cd treatment. The zat10 mutant plants exhibited a greater sensitivity to Cd stress 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.

In this mini review, we broadly discuss the different Zn tolerance mechanisms and then focus on controlled Zn uptake in A. halleri. Members of the ZRT/IRT-like protein (ZIP) family of metal transporters are mainly regulated by Zn and are involved in Zn uptake. A few members of the ZIP family, such as IRT1 and IRT2, are regulated by iron (Fe ...

Role of Ethylene in Plant Growth under Low K + Stress.

Cold shock triggers an immediate rise in the cytosolic free calcium concentration ([Ca 2+] cyt) in Arabidopsis thaliana and this cold-induced elevation of [Ca 2+] cyt is inhibited by lanthanum or EGTA. It is suggested that intracellular calcium mainly contributes to the cold-induced [Ca 2+] cyt response by entering into the cytosol. Two …
