| Title: Involvement of ASR genes in aluminium tolerance mechanisms in rice .
| | Author: Arenhart RA DE Lima JC Pedron M Carvalho FE DA Silveira JA Rosa SB Caverzan A Andrade CM Schunemann M Margis R Margis-Pinheiro M | | Journal: Plant Cell Environ Citation: V : P : Year: 2012 Type: Publisher | | Literature: oryza Field: abstract Doc ID: pub22676236 Accession (PMID): 22676236 | | Abstract: Among cereal crops , rice is considered the most tolerant to aluminium ( Al ) .
However , variability among rice genotypes leads to remarkable differences in the degree of Al tolerance for distinct cultivars .
A number of studies have demonstrated that rice plants achieve Al tolerance through an unknown mechanism that is independent of root tip Al exclusion .
We have analysed expression changes of the rice ASR gene family as a function of Al treatment .
The gene ASR5 was differentially regulated in the Al-tolerant rice ssp .
Japonica cv .
Nipponbare .
However , ASR5 expression did not respond to Al exposure in Indica cv .
Taim rice roots , which are highly Al sensitive .
Transgenic plants carrying RNAi constructs that targeted the ASR genes were obtained , and increased Al susceptibility was observed in T1 plants .
Embryogenic calli of transgenic rice carrying an ASR5-green fluorescent protein fusion revealed that ASR5 was localized in both the nucleus and cytoplasm .
Using a proteomic approach to compare non-transformed and ASR-RNAi plants , a total of 41 proteins with contrasting expression patterns were identified .
We suggest that the ASR5 protein acts as a transcription factor to regulate the expression of different genes that collectively protect rice cells from Al-induced stress responses .

| Title: Identification and characterization of a gibberellin-regulated protein , which is ASR5 , in the basal region of rice leaf sheaths .
| | Author: Takasaki H Mahmood T Matsuoka M Matsumoto H Komatsu S | | Journal: Mol Genet Genomics Citation: V : 279 P : 359-70 Year: 2008 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub18210155 Accession (PMID): 18210155 | | Abstract: Gibberellins ( GAs ) regulate growth and development in higher plants .
To identify GA-regulated proteins during rice leaf sheath elongation , a proteomic approach was used .
Proteins from the basal region of leaf sheath in rice seedling treated with GA ( 3 ) were analyzed by fluorescence two-dimensional difference gel electrophoresis .
The levels of abscisic acid-stress-ripening-inducible 5 protein ( ASR5 ) , elongation factor-1 beta , translationally controlled tumor protein , fructose-bisphosphate aldolase and a novel protein increased ; whereas the level of RuBisCO subunit binding-protein decreased by GA ( 3 ) treatment .
ASR5 out of these six proteins was significantly regulated by GA ( 3 ) at the protein level but not at the mRNA level in the basal region of leaf sheaths .
Since this protein is regulated not only by abscisic acid but also by GA ( 3 ) , these results indicate that ASR5 might be involved in plant growth in addition to stress in the basal regions of leaf sheaths .

| Title: Clustered genes required for synthesis and deposition of envelope glycolipids in Anabaena sp . strain PCC 7120 .
| | Author: Fan Q Huang G Lechno-Yossef S Wolk CP Kaneko T Tabata S | | Journal: Mol . Microbiol . Citation: V : 58 ( 1 ) P : 227-43 Year: 2005 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16164561 Accession (PMID): 16164561 | | Abstract: Photoreduction of dinitrogen by heterocyst-forming cyanobacteria is of great importance ecologically and for subsistence rice agriculture .
Their heterocysts must have a glycolipid envelope layer that limits the entry of oxygen if nitrogenase is to remain active to fix dinitrogen in an oxygen-containing milieu ( the Fox+ phenotype ) .
Genes alr5354 ( hglD ) , alr5355 ( hglC ) and alr5357 ( hglB ) of the filamentous cyanobacterium , Anabaena sp . strain PCC 7120 , and hglE of Nostoc punctiforme are required for synthesis of heterocyst envelope glycolipids .
Newly identified Fox mutants bear transposons in nearby open reading frames ( orfs ) all5343 , all5345-asr5349 and alr5351-alr5358 .
Complementation and other analysis provide evidence that at least orfs all5343 ( or a co-transcribed gene ) , all5345 , all5347 , alr5348 , asr5350-alr5353 and alr5356 , but not asr5349 , are also required for a Fox+ phenotype .
Lipid and sequence analyses suggest that alr5351-alr5357 encode the enzymes that biosynthesize the glycolipid aglycones .
Electron microscopy indicates a role of all5345 through all5347 in the normal deposition of the envelope glycolipids .
