• Genetic and physiological analysis of a novel type of interspecific hybrid weakness in rice, 2013, Mol Plant.

Genbank accession number

• The dominant Hybrid weakness i1 (Hwi1) gene from wild rice is genetically incompatible with Teqing and induced a set of weakness symptoms, including growth suppression, yield decrease, impaired nutrient absorption, and the retardation of crown root initiation

• Hwi1, Hwi2, A two-locus interaction causes interspecific hybrid weakness in rice., Here we show that two incompatible dominant loci (Hwi1 and Hwi2) involving three genes are likely to determine the high temperature-dependent expression of hybrid weakness in interspecific hybrids of rice
• Hwi1, Hwi2, A two-locus interaction causes interspecific hybrid weakness in rice., Functional analysis indicated that pyramiding of Hwi1 and Hwi2 activates the autoimmune response in the basal nodes of hybrids, interrupting root formation and then impairing shoot growth
