“…Also interesting is that the gene that showed the biggest up-regulation in S. pinnata, PDF1.2, encodes a small and extremely Cys-rich pathogen defensin protein (Broekaert et al, 1995;Penninckx et al, 1996). Overproduction of a similar plant defensin from the zinc hyperaccumulator Arabidopsis halleri (AhPDF1.1) in Arabidopsis led to a significant increase in resistance to zinc and selenite (Mirouze et al, 2006;Tamaoki et al, 2008a). Considering the known role for Se in S. pinnata elemental defense (for review, see Quinn et al, 2007), one may envision the presence of a SeCysrich toxic defense protein.…”

“…These results might be attributed to the Se-adapted hormonal balance, especially salicylic acid, jasmonic acid, and ethylene, thereby stimulating defense related responses. Inductions of expression of many ethylene and/or jasmonate related genes because of selenate treatment have been documented (Tamaoki et al, 2008). An increase in salicylic acid, a major phenylpropanoid involved in plant acclimatization to various stressors, has been observed in selenium-treated Arabidopsis (Tamaoki et al, 2008).…”

An increase in salicylic acid, a major phenylpropanoid involved in plant acclimatization to various stressors, has been observed in selenium-treated Arabidopsis (Tamaoki et al, 2008). Rises in phenylalanine contents have been reported in Se-fertilized plants (Munshi et al, 1990;Ježek et al, 2011).…”

“…[ 106 ] о в о щ и р о с с и и № 3 ( 2 8 ) 2 0 1 5 ждать, что устойчивость растений-гипераккумуляторов Se к высоким концентрациям микроэлемента связана с активным син-тезом этилена, салициловой и жасминовой кислот [17,18]. Интересно в связи с этим отметить, что при низких концентрациях Sе, напротив, снижает производство этилена растениями [13] (табл.2).…”
