WebOct 15, 2024 · In this study, we demonstrate that a coiled-coil nucleotide-binding site leucine-rich repeat (CC-NBS-LRR) gene is the causal gene underlying the Le4 locus for interspecific hybrid lethality between Gossypium barbadense and G. hirsutum (cotton). Silencing this CC-NBS-LRR gene can restore F1 plants from a lethal to a normal … Lethal alleles (also referred to as lethal or lethals) are alleles that cause the death of the organism that carries them. They are usually a result of mutations in genes that are essential for growth or development. Lethal alleles may be recessive, dominant, or conditional depending on the gene or genes involved.

WebNov 15, 2013 · The proof of principle that the synthetic lethality concept is clinically translatable is the efficacy of drugs that target the single-strand DNA repair enzyme poly (ADP-ribose) polymerase (PARP) in tumors with mutations in the BRCA1 and BRCA2 genes ( 7 ). These genes encode tumor suppressor proteins that help repair damaged DNA.
