“…In a few reports, TRXs have been shown to be involved in pathogenic responses (Rivas et al, 2004;Sweat and Wolpert, 2007;Tada et al, 2008), hypersensitiviy to oxidants (Broin et al, 2000(Broin et al, , 2002Broin and Rey, 2003), cytochrome b(6)f biosynthesis (Lennartz et al, 2001), and plasmodesmal transport in meristems (Benitez-Alfonso et al, 2009). Recently, genetic evidence has revealed functions of GRX-like proteins in flower development (Xing et al, 2005;Xing and Zachgo, 2008;Li et al, 2009).…”
