The mitochondrial genome of allotetraploid cotton (Gossypium L.)

Knowledge of patterns of organellar inheritance are crucial for analyses of organellar genetics and population or phylogenetic analyses based on organ ellar genes. While it has previously been shown that chloroplast DNA is mat ernally inherited in cotton (Gossypium L.), no studies have assessed the mi tochondrial genome complement of the allotetraploid species of cotton or ad dressed inheritance of mitochondrial DNA. In this article we report Souther n hybridization analyses that indicate that the AD-genome allotetraploid sp ecies have an A-genome-like mitochondrial genome and provide evidence that mitochondrial genomes are also maternally inherited in cotton.
