Rice has great potential to investigate and understand this phenomenon as weakness phenotype is observed in numerous intra and inter-specific crosses (Amemiya and Akamine 1963;Sato and Morishima 1988;Fukuoka et al 1998Fukuoka et al , 2005Kubo and Yoshimura 2002;Matsubara et al 2007;Yamamoto et al 2007;Miura et al 2008).…”

Reproductive isolation plays an important role in speciation as it restricts gene flow and accelerates genetic divergence between formerly interbreeding population. In rice, hybrid breakdown is a common reproductive isolation observed in both intra and inter-specific crosses. It is a type of post-zygotic reproductive isolation in which sterility and weakness are manifested in the F(2) and later generations. In this study, the physiological and molecular basis of hybrid breakdown caused by two recessive genes, hbd2 and hbd3, in a cross between japonica variety, Koshihikari, and indica variety, Habataki, were investigated. Fine mapping of hbd2 resulted in the identification of the causal gene as casein kinase I (CKI1). Further analysis revealed that hbd2-CKI1 allele gains its deleterious function that causes the weakness phenotype by a change of one amino acid. As for the other gene, hbd3 was mapped to the NBS-LRR gene cluster region. It is the most common class of R-gene that triggers the immune signal in response to pathogen attack. Expression analysis of pathogen response marker genes suggested that weakness phenotype in this hybrid breakdown can be attributed to an autoimmune response. So far, this is the first evidence linking autoimmune response to post-zygotic isolation in rice. This finding provides a new insight in understanding the molecular and evolutionary mechanisms establishing post-zygotic isolation in plants.

“…In rice, hybrid weakness has been reported in some inter-specific and intra-specific combinations (Oka 1957, Amemiya and Akemine 1963, Chu and Oka 1972, Sato and Hayashi 1983, Sato and Morishima 1987, Sato and Morishima 1988, Okuno 1985, Kubo and Yoshimura 2002, Matsubara et al 2007, Yamamoto et al 2007. The F 1 hybrid weakness (F 1 HW) of rice has been genetically explained by the function of a set of complementary genes (Oka 1957, Amemiya and Akemine 1963, Chu and Oka 1972, Sato and Hayashi 1983, Ichitani et al 2001.…”

Developmental Observation and High Temperature Rescue from Hybrid Weakness in a Cross between Japanese Rice Cultivars and Peruvian Rice Cultivar 'Jamaica'

et al. 2007

The weak growth occurring in hybrids derived from crosses between two normal strains is referred to as hybrid weakness. F 1 hybrid weakness (F 1 HW) in a cross between a Peruvian rice cultivar 'Jamaica' and Japanese rice cultivars has been reported and was considered to be controlled by a set of complementary genes, Hwc1 and Hwc2. We observed the development of F 1 plants between Nipponbare and Jamaica (NJF 1 s). NJF 1 s were characterized by short roots, rolled leaves and a short stature. Although the NJF 1 embryos were normal, the growth of the primary roots was arrested and in most cases, they could not emerge from seeds of the hybrids. Histological observation of the root apical meristem (RAM) at 10 days after sowing revealed that the zone of cell division in the NJF 1 plants was lost, and that the cells were not short enough to explain the reduced root length of the NJF 1 plants. Thus, it was suggested that the shorter roots the NJF 1 plants might be due to reduced cell division. Although no distinct morphological abnormalities in the shoot apical meristem were observed, leaf primordium production was delayed in the NJF 1 plants. Inhibition of root elongation in this type of hybrid weakness was alleviated under high temperature (34°C) conditions in diverse genetic backgrounds. The threshold temperature required for the recovery of root growth from hybrid weakness seemed to range from 29 to 30°C. Among 85 NJF 1 plants that germinated and grew at 34°C for 10 days, and then outdoors, 18 plants eventually flowered. These plants were dwarf and their flowering time was delayed compared with that of their parents. In spite of their abnormal development, they were fertile. Thus, it is suggested that high temperature treatment was also effective to overcome hybrid weakness and to obtain next generation in this cross combination.

“…Many reports are available on the genetic analysis of hybrid breakdown in rice (Oka 1957, 1978, Oka and Doida 1962, Yokoo 1984, Sato and Morishima 1988, Wu et al 1995, Li et al 1997, Kubo and Yoshimura 2002, Fukuoka et al 2005, Yamamoto et al 2007, Matsubara et al 2007a, 2007b. These studies demonstrated that hybrid breakdown is induced by the interaction of two or three genes derived from each parent.…”

The hybrid breakdown 1(t) locus induces interspecific hybrid breakdown between rice Oryza sativa cv. Koshihikari and its wild relative O. nivara

Reproductive barriers are often observed in progenies derived from crosses between relatively distant species, such as cultivated varieties and their wild relatives. Such barriers hinder the transfer of agronomically important genes from one species to another. In the process of constructing a series of introgression lines (ILs) between Oryza sativa japonica cv. Koshihikari and wild species O. nivara, we observed the occurrence of hybrid breakdown, a reproductive barrier observed in F 2 and later generations. Plants affected by this hybrid breakdown show extremely weak growth and die before heading. Linkage analysis and construction of ILs indicated that the locus -hbd1(t), located on the short arm of chromosome 2 of O. nivara, induces hybrid breakdown in the Koshihikari genetic background. hbd1(t) is identical to hbd1, which was previously identified in a cross between Koshihikari and Nona Bokra (indica) cultivars of O. sativa. We present genetic evidence that hbd1(t) regulates hybrid breakdown and its location within 50 kb. Possible reasons for this locus being responsible for hybrid breakdown in inter-and intraspecific crosses are discussed.
