Pentatricopeptide repeat 336 as the candidate gene for paternal sorting of mitochondria (Psm) in cucumber.

ABSTRACT:

Key message

Pentatricopeptide repeat (PPR) 336 was identified as the candidate gene for Paternal Sorting of Mitochondria ( Psm ), a nuclear locus that affects the predominant mitochondria transmitted to progenies. Cucumber (Cucumis sativus L.) is a useful plant to study organellar-nuclear interactions because its organelles show differential transmission, maternal for chloroplasts and paternal for mitochondria. The mitochondrial DNA (mtDNA) of cucumber is relatively large due in part to accumulation of repetitive DNAs and recombination among these repetitive regions produces structurally polymorphic mtDNAs associated with paternally transmitted mosaic (MSC) phenotypes. The mitochondrial mutant MSC16 possesses an under-representation of ribosomal protein S7 (rps7), a key component o
