High impact information on SDH2-2

  • Progressive deletions of the promoters identified regions important for SDH2-1 expression in anthers and/or pollen and for SDH2-2 expression in anthers and/or pollen and root tips [1].
  • In contrast to SDH2-3 transcripts, SDH2-1 and SDH2-2 transcripts are barely detected in dry seeds and increase during germination and post-germinative growth [2].

Anatomical context of SDH2-2

  • As flowers develop, SDH2-1 and SDH2-2 transcripts accumulate in anthers, particularly in the tapetum, pollen mother cells, and microspores, in agreement with an essential role of mitochondria during anther development [1].

Other interactions of SDH2-2

  • SDH2-1 and SDH2-2 probably arose via a recent duplication event and we reported that both are expressed in all organs from adult plants [2].

Analytical, diagnostic and therapeutic context of SDH2-2


  1. Nuclear SDH2-1 and SDH2-2 genes, encoding the iron-sulfur subunit of mitochondrial complex II in Arabidopsis, have distinct cell-specific expression patterns and promoter activities. Elorza, A., León, G., Gómez, I., Mouras, A., Holuigue, L., Araya, A., Jordana, X. Plant Physiol. (2004) [Pubmed]
  2. A nuclear gene for the iron-sulfur subunit of mitochondrial complex II is specifically expressed during Arabidopsis seed development and germination. Elorza, A., Roschzttardtz, H., Gómez, I., Mouras, A., Holuigue, L., Araya, A., Jordana, X. Plant Cell Physiol. (2006) [Pubmed]
