Title: A chloroplast derived trnH gene is expressed in the mitochondrial genome of gramineous plants. Author: Kanno A, Nakazono M, Hirai A, Kameya T. Journal: Plant Mol Biol; 1997 May; 34(2):353-6. PubMed ID: 9207852. Abstract: We reported previously that the mitochondrial sequence that contains the chloroplast-derived trnH gene has been highly conserved in the region around one terminus of the junction between chloroplast-derived and mitochondrion-specific sequences in most of the gramineous plants analyzed [15]. The results of RT-PCR, northern hybridization, in vitro capping and ribonuclease protection experiments show that the chloroplast-derived trnH gene is transcribed from a putative promoter that is located in the mitochondrion-specific sequence. Gene expression in this region seems to be correlated with the conservation of the sequence at the junction between the chloroplast-derived fragment and the mitochondrion-specific sequence.[Abstract] [Full Text] [Related] [New Search]
