“…Moreover, exploiting CWR resistances could be a way to unravel even more effective resistance genes. Indeed, Wang et al (2019) showed that the Hb LecRLK gene of resistance to leaf rust Rph22 confers a stronger resistance to leaf rust adapted to Hv than its Hv ortholog Rphq2. The hypothesis is that crop receptors have a lower recognition of crop-adapted pathogens than the CWR receptors because of adaptation of the pathogens during centuries of coevolution with their host plant.…”

“…Besides, there is no doubt on the importance of PRRs in plant disease resistance in any model. Research reports on seeking resistance genes from LecRK family have increasingly appeared in recent years [11][12][13], reflecting the importance of LecRKs in plant disease-resistant breeding. An L-type LecRK-V accession from Haynaldia villosa markedly enhanced the powdery mildew resistance at both seedling and adult stages of wheat Yangmai158 [11].…”

“…LORE, belonging to a G-type protein and conferring sensitivity to lipopolysaccharide in tobacco, may increase the resistance to bacteria in crops [12]. The Rphq2 and Rph22 loci in cultivated barley (Hordeum vulgare) and wild bulbous barley, respectively, could affect the resistance of barley to leaf rust [13]. In addition, both genes encode lectin receptor kinase Hv-LecRK, and overexpression of Hv-LecRK in "Golden SusPtrit" barley varieties, which is susceptible to non-host leaf rust pathogen, can significantly improve the resistance of barley to leaf rust [13].…”

Sugarcane is an important sugar and bioenergy ethanol crop, and the hyperploidy has led to stagnant progress in sugarcane genome decipherment, which also hindered the genome-wide analyses of versatile lectin receptor kinases (LecRKs). The published genome of Saccharum spontaneum, one of the two sugarcane ancestor species, enables us to study the characterization of LecRKs and their responses to sugarcane leaf blight (SLB) triggered by Stagonospora tainanensis. A total of 429 allelic and non-allelic LecRKs, which were classified into evolved independently three types according to signal domains and phylogeny, were identified based on the genome. Regarding those closely related LecRKs in the phylogenetic tree, their motifs and exon architectures of representative L- and G-types were similar or identical. LecRKs showed an unequal distribution on chromosomes and more G-type tandem repeats may come from the gene expansion. Comparing the differentially expressed LecRKs (DELs) in response to SLB in sugarcane hybrid and ancestor species S. spontaneum, we found that the DEL number in the shared gene sets was highly variable among each sugarcane accession, which indicated that the expression dynamics of LecRKs in response to SLB were quite different between hybrids and particularly between sugarcane hybrid and S. spontaneum. In addition, C-type LecRKs may participate in metabolic processes of plant–pathogen interaction, mainly including pathogenicity and plant resistance, indicating their putative roles in sugarcane responses to SLB infection. The present study provides a basic reference and global insight into the further study and utilization of LecRKs in plants.

“…Minor effect QTLs for partial resistance to BLR (Rphq2, Rphq3 and Rphq4) were previously identified by Qi et al (1998) in the Vada x L94 mapping population. Rphq2 has been recently cloned and is involved in increased latency period, but is largely ineffective at adult growth stages (Wang et al 2020). Rphq4 and Rph20 are regarded as the same major effect QTL and Rphq3 is assumed to be the same as Rph24 however further genetic evidence is required for confirmation.…”

Validating Molecular Markers for Barley Leaf Rust Resistance Genes Rph20 and Rph24

Improving resistance to barley leaf rust (caused by Puccinia hordei) is an important breeding objective in most barley growing regions worldwide. The development and subsequent utilization of high-throughput polymerase chain reaction (PCR) based co-dominant molecular markers remains an effective approach to select genotypes with multiple effective resistance genes, permitting efficient gene deployment and stewardship. The genes Rph20 and Rph24, which confer widely effective adult plant resistance (APR) to leaf rust, are common in European and Australian barley germplasm (often in combination), and act interactively to confer high levels of resistance. Here we report on the development and validation of co-dominant insertion-deletion (indel) based PCR markers that are highly predictive for the resistance alleles Rph20.ai and Rph24.an (both referred to as Rph20 and Rph24).
