For instance, exposure to excess NaCl for 2 min leads to high Na + accumulation in Arabidopsis roots (Essah et al., 2003). Since the Na + and K + share the transport system, the uptake of K + into plant cells might be repressed by elevated Na + in the soil, leading to K + deficiency in plants (Blumwald et al., 2000; Rodríguez-Navarro and Rubio ...

We have studied the physiological and genetic responses of Arabidopsis thaliana L. (Arabidopsis) to gold. The root lengths of Arabidopsis seedlings grown on nutrient agar …

For example GNPs were found in Arabidopsis cells when plants were grown on gold salts [52]. Nanoparticles accumulated mainly in chloroplasts. Nanoparticles accumulated mainly in chloroplasts. It is suggested that the formation of nanoparticles can serve as a detoxification agent for plants when the soil is contaminated with metal pollutants [52] .

The Zn hyperaccumulator Arabidopsis halleri has developed various adaptive mechanisms involving uptake, chelation, translocation and sequestration of Zn. 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 ...

Members of the aquaporin (AQP) family have been suggested to transport aluminum (Al) in plants; however, the Al form transported by AQPs and the roles of AQPs in Al tolerance remain elusive. Here we report that NIP1;2, a plasma membrane-localized member of the Arabidopsis nodulin 26-like intr …

of nanoparticle uptake by plants [19,23]. Gold Uptake at the Genetic Level Several studies have investigated the binding of various states of gold to root membranes [17,24], but at the genetic level, the mechanism for gold uptake remains unclear. In Arabidopsis, heavy metal ATPases (HMAs), which translocate ions across cell or

After PTE uptake, many hyperaccumulators undergo cellular secretion of chelates supported by enzymatic catalysis and high transport systems with the ability to form complexes as tolerance and ...

In this chapter, we focus on the mechanisms of HM tolerance in Arabidopsis and include recent progress that has been made in molecular biological and genomic studies in this field. ...

(A) Leaf K concentration among 349 accessions. The arrow and back bar indicate the tetraploid, Wa-1. DW, dry weight. (B to F) Box plots (the minimum, first quartile, median, third quartile, and maximum are shown, with data >1.5 interquartile ranges denoted with circles) for leaf K concentration in Col-0 x Wa-1 RILs (B), Wa-1 and diploid Wa-1 (C), natural tetraploid …

Growth-promoting AuNPs can reduce the responses to stress in Arabidopsis (Ferrari et al., 2021). AuNPs synthesized by melatonin or astaxanthin can also alleviate the toxicity of cadmium and decrease its uptake in rice (Jiang et al., 2021b; Dai et al., 2021). Astaxanthin, an effective and natural antioxidant, in combination with AuNPs may be ...

Factors influencing Pi uptake can be broadly classified into five categories: soil Pi concentration, phytohormone content, Pi uptake, and transport transcription factor (TF) activity, glycan signaling, and microRNAs (Jabnoune et al., 2013, Du et al., 2018, Prerostova et al., 2018, Wang et al., 2020).TFs are mainly found in the nucleus; they bind specifically to short upstream …

Loss-of-function of ZAT10 lead to increased cadmium sensitivity. To characterize the function of ZAT10 in plant Cd-tolerance, we obtained the Arabidopsis T-DNA insertional mutant zat10 (SALK_054092C) from the SALK T-DNA collection (Figure 2A; Mittler et al., 2006) and generated complementary lines expressing ZAT10pro:ZAT10 in the zat10 background. …

These results indicate that exogenous Cys regulates the transcript levels of heavy metal chelators and antioxidative enzymes differently in a time- and organ-specific manner under Hg stress. Taken together, our study elucidates the positive functional roles of exogenous Cys in the Hg uptake and tolerance mechanisms of Arabidopsis.

Information on cadmium (Cd) uptake and transport is essential to understand better the physiology of Cd tolerance in plants. In this study, Cd uptake, translocation, and tolerance were investigated in AHA1 (Arabidopsis plasma membrane H+-ATPase gene) overexpressed plants. Exposed to 10 µM CdCl2, AHA1OX showed a higher root elongation, …

AKT1 (Arabidopsis K + transporter 1) has been demonstrated as an inward-rectifying K + channel in A. thaliana that mediates K + uptake into the roots [[26], [27], [28], [29]].The K + channel AKT1 is primarily expressed in the roots, particularly in mature epidermis, cortex, and endodermis, which is the prerequisite for the function of root K + uptake [26, 30, 31].

Exogenous L-DOPA triggers iron (Fe) uptake by roots of Arabidopsis thaliana Columbia-0 ecotype through transcriptional activation of Fe deficiency genes, including IRONMANs (IMAs), which encode peptides regulating Fe homeostasis. Ectopic expression of IRONMAN1 was reported to enhance Cd tolerance in Arabidopsis. We therefore hypothesized …

Strain HYN0056 T Improves the Salt Stress Tolerance of Arabidopsis. The drought- and salt stress-signaling pathways largely share the protein components that are used to overcome such stresses (Lee and Kim 2011).Since strain HYN0056 T altered the sensitivity to drought stress in Arabidopsis, we investigated if the tolerance against salt stress could be …

Although some of MTs in Arabidopsis play pivotal role in Cu homeostasis, these results indicated that Arabidopsis MTs coordinately regulated HM tolerance with other HM …

Because previous studies has suggested that AtAAP1 and AtLHT1 might play roles in the uptake of neutral amino acids by Arabidopsis roots (Himer et al., 2006; Lee et al., 2007; Perchlik et al., 2014), we investigated whether these amino acid transporters are also involved in Hg uptake into Arabidopsis roots, given that Cys belongs to the family ...
