RPT5a (Regulatory Particle 5a), one of the six AAA-ATPases of the proteasome regulatory particle. It’s essential for gametophyte development. In Arabidopsis, the RPT5 subunit is encoded by two highly homologous genes, RPT5a and RPT5b. RPT5a and RPT5b show accession-dependent functional redundancy.
PPK3 is involved in phosphorylation and ubiquination of RYR/PYLs, resulting in negative regulation of ABA response. Also acts in GA response pathway along with RGA1/CCA1.
NDHF is involved in the transfer of electrons from NAD(P)H: plastoquinone, via FMN and iron-sulfur centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory chain.
FC2 is one of two ferrochelatase genes in Arabidopsis. Ferrochelatase is the terminal enzyme of heme biosynthesis. FC-II is speculated to operate in photosynthetic cytochromes.
GOX1/2 are glycolate oxidases that modulate reactive oxygen species- mediated signal transduction during nonhost resistance. The mRNA is cell-to- cell mobile.
