“…The molecular chaperone, heat shock protein 90 (HSP90), and two interacting co-chaperons, required for Mla12 resistance (RAR1) and suppressor of G2 allele of skp1 (SGT1), form a complex that interacts with many NBS-LRRs, also known as NLRs ( Kadota et al., 2010 ; Kadota and Shirasu, 2012 ; Balint-Kurti, 2019 ). Agrobacterium -mediated transient expression of RAR1 as well as SGT1 derived from N. gossei (a wild relative of N. tabacum ) induced cell death in N. tabacum , whereas the transient expression of those genes derived from N. tabacum did not ( Katsuyama et al., 2021 ). Additionally, a specific inhibitor of HSP90, geldanamycin, suppressed cell death in type II hybrid seedling lethality.…”

“…These findings suggest the involvement of HSP90-SGT1-RAR1 complex in type II hybrid seedling lethality. Because each species has established an appropriate set of chaperons, the chaperons may be incompatible with those from other species ( Katsuyama et al., 2021 ; Mino et al., 2022 ).…”

Hybrid lethality is a type of reproductive isolation barrier observed in two developmental stages, hybrid embryos (hybrid seeds) and hybrid seedlings. Hybrid lethality has been reported in many plant species and limits distant hybridization breeding including interspecific and intergeneric hybridization, which increases genetic diversity and contributes to produce new germplasm for agricultural purposes. Recent studies have provided molecular and genetic evidence suggesting that underlying causes of hybrid lethality involve epistatic interaction of one or more loci, as hypothesized by the Bateson–Dobzhansky–Muller model, and effective ploidy or endosperm balance number. In this review, we focus on the similarities and differences between hybrid seed lethality and hybrid seedling lethality, as well as methods of recovering seed/seedling activity to circumvent hybrid lethality. Current knowledge summarized in our article will provides new insights into the mechanisms of hybrid lethality and effective methods for circumventing hybrid lethality.

“…Considering that some types of disease resistance responses are temperature sensitive [27][28][29] and involve programmed cell death [30], the results from the experiments on hybrid lethality in Nicotiana have suggested that disease resistance-related responses might be associated with hybrid lethality. Several genes and proteins also relevant to disease resistance have been identified in the process of hybrid lethality [31][32][33][34]. However, the causal genes for hybrid lethality in Nicotiana are poorly understood.…”

Hybrid lethality, a postzygotic mechanism of reproductive isolation, is a phenomenon that causes the death of F1 hybrid seedlings. Hybrid lethality is generally caused by the epistatic interaction of two or more loci. In the genus Nicotiana, N. debneyi has the dominant allele Hla1-1 at the HLA1 locus that causes hybrid lethality in F1 hybrid seedlings by interaction with N. tabacum allele(s). Here, we mapped the HLA1 locus using the F2 population segregating for the Hla1-1 allele derived from the interspecific cross between N. debneyi and N. fragrans. To map HLA1, several DNA markers including random amplified polymorphic DNA, amplified fragment length polymorphism, and simple sequence repeat markers, were used. Additionally, DNA markers were developed based on disease resistance gene homologs identified from the genome sequence of N. benthamiana. Linkage analysis revealed that HLA1 was located between two cleaved amplified polymorphic sequence markers Nb14-CAPS and NbRGH1-CAPS at a distance of 10.8 and 10.9 cM, respectively. The distance between these markers was equivalent to a 682 kb interval in the genome sequence of N. benthamiana.
