| Title: The ndhH genes of gramminean plastomes are linked with the junctions between small single copy and inverted repeat regions .
| | Author: Maier RM Dry I Igloi G Kssel H | | Journal: Curr . Genet . Citation: V : 18 ( 3 ) P : 245-50 Year: 1990 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub2249254 Accession (PMID): 2249254 | | Abstract: The junctions JSA and JSB between the two inverted repeat regions IRA and IRB and the small single copy region of the maize chloroplast DNA have been identified by DNA sequencing .
The JSA junction coincides with the initiation codon of the ndhH gene which is encoded by the adjacent region of the small single copy region .
A comparison with the plastomes of rice , rye , tobacco and liverwort shows that linkage of this junction with the ndhH gene is specific for gramminean species .
The amino acid sequences deduced from the ndhH genes show conserved histidine and cysteine residues which are likely to form a metal-binding domain .

| Title: Complete chloroplast genome sequences of Hordeum vulgare , Sorghum bicolor and Agrostis stolonifera , and comparative analyses with other grass genomes .
| | Author: Saski C Lee SB Fjellheim S Guda C Jansen RK Luo H Tomkins J Rognli OA Daniell H Clarke JL | | Journal: Theor Appl Genet Citation: V : 115 P : 571-90 Year: 2007 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub17534593 Accession (PMID): 17534593 | | Abstract: Comparisons of complete chloroplast genome sequences of Hordeum vulgare , Sorghum bicolor and Agrostis stolonifera to six published grass chloroplast genomes reveal that gene content and order are similar but two microstructural changes have occurred .
First , the expansion of the IR at the SSC/IRa boundary that duplicates a portion of the 5 end of ndhH is restricted to the three genera of the subfamily Pooideae ( Agrostis , Hordeum and Triticum ) .
Second , a 6 bp deletion in ndhK is shared by Agrostis , Hordeum , Oryza and Triticum , and this event supports the sister relationship between the subfamilies Erhartoideae and Pooideae .
Repeat analysis identified 19-37 direct and inverted repeats 30 bp or longer with a sequence identity of at least 90% .
Seventeen of the 26 shared repeats are found in all the grass chloroplast genomes examined and are located in the same genes or intergenic spacer ( IGS ) regions .
Examination of simple sequence repeats ( SSRs ) identified 16-21 potential polymorphic SSRs .
Five IGS regions have 100% sequence identity among Zea mays , Saccharum officinarum and Sorghum bicolor , whereas no spacer regions were identical among Oryza sativa , Triticum aestivum , H vulgare and A stolonifera despite their close phylogenetic relationship .
Alignment of EST sequences and DNA coding sequences identified six C-U conversions in both Sorghum bicolor and H vulgare but only one in A stolonifera .
Phylogenetic trees based on DNA sequences of 61 protein-coding genes of 38 taxa using both maximum parsimony and likelihood methods provide moderate support for a sister relationship between the subfamilies Erhartoideae and Pooideae .
