The Arabidopsis Ethylene-Insensitive 2 gene is required for lead resistance

Cross Talk between Nitric Oxide and Phytohormones Regulate Plant Development during Abiotic Stresses

“…Similarly, integration of ET, NO, PA, and MAPKs pathways improved tolerance in young Glycine max seedlings against short-term Cd stress [52]. The potential involvement of ETHYLENE INSENSITIVE2 (EIN2) in improving resistance against lead (Pb) stress has also been demonstrated in Arabidopsis [65]. Treatment of Triticum aestivum seedlings with Cd and PAs (spermine and putrescine) was found to induce NO generation in roots leading to root growth inhibition [66].…”

The Full-Size ABCG Transporters Nb-ABCG1 and Nb-ABCG2 Function in Pre- and Postinvasion Defense against Phytophthora infestans in Nicotiana benthamiana

“…Arabidopsis abcg40 mutants also showed enhanced sensitivity to lead; thus, At-ABCG40 is presumed to be a pump that excludes lead or leadcontaining compounds from the cytoplasm. Lead-induced expression of At-ABCG40 was impaired in ein2 mutants, indicating that expression of this gene is also regulated by ethylene (Cao et al, 2009). A more recent report indicated that At-ABCG40 is also involved in the import of the sesquiterpenoid hormone abscisic acid (ABA) (Kang et al, 2010).…”

Zinc-Finger Transcription Factor ZAT6 Positively Regulates Cadmium Tolerance through the Glutathione-Dependent Pathway in Arabidopsis

“…In addition, a lot of key genes have been shown to be involved in Cd detoxification and tolerance in plants. These include ZNT1, OsHMA9, OsNRAMP5, ZntA, CAD2, AtPDR12, AtPDR8, AtATM3, ACBP1, Nramp5, EIN2, and MAN3 (Pence et al, 2000;Sharma et al, 2000;Shiraishi et al, 2000;Lee et al, 2003Lee et al, , 2007Kim et al, 2006Kim et al, , 2007Xiao et al, 2008;Cao et al, 2009;Lin and Aarts, 2012;Sasaki et al, 2012;Ishikawa et al, 2012;Chen et al, 2015). It was also found that Heat shock transcription factor A4a (HsfA4a) confers Cd tolerance by up-regulating MT gene expression in wheat (Triticum aestivum) and rice (Oryza sativa; Shim et al, 2009).…”
