OsBSK1-2, an Orthologous of AtBSK1, Is Involved in Rice Immunity.

ABSTRACT: The brassinosteroid-SIGNALING KINASE (BSK) belongs to the receptor-like cytoplasmic kinase XII subgroup. BSK1 regulates development and immunity in Arabidopsis. However, the function of rice (Oryza sativa) BSK1 is largely unknown. Here, we report that the expression level of OsBSK1-2 is induced after a chitin or fagellin22 (flg22) treatment. Silencing OsBSK1-2 in rice results in compromised responses to chitin- or flg22-triggered immunity and resistance to Magnaporthe oryzae, but does not alter the plant's architecture nor reduce plant responses to brassinosteroid signaling. Our study reveals that OsBSK1-2 functions as a major regulator in rice plant immunity.

Divergent functions of orthologous NAC transcription factors in wheat and rice.

Project description:The wheat GPC-B1 gene located on chromosome 6B is an early regulator of senescence and affects remobilization of protein and minerals to the grain. GPC-B1 is a NAC transcription factor and has a paralogous copy on chromosome 2B in wheat, GPC-B2. The closest rice homolog to both wheat GPC genes is Os07g37920 which is located on rice chromosome 7 and is colinear with GPC-B2. Since rice is a diploid species with a sequenced genome, we initiated the study of Os07g37920 to develop a simpler model to study senescence and mineral remobilization in cereals. We developed eleven independent RNA interference transgenic rice lines (Os07g37920-RNAi) and 10 over-expressing transgenic lines (Os07g37920-OE), but none of them showed differences in senescence. Transgenic Os07g37920-RNAi rice plants had reduced proportions of viable pollen grains and were male-sterile, but were able to produce seeds by cross pollination. Analysis of the flower morphology of the transgenic rice plants showed that anthers failed to dehisce. Transgenic Os07g37920-OE lines showed no sterility or anther dehiscence problems. Os07g37920 transcript levels were higher in stamens compared to leaves and significantly reduced in the transgenic Os07g37920-RNAi plants. Wheat GPC genes showed the opposite transcription profile (higher transcript levels in leaves than in flowers) and plants carrying knock-out mutations of all GPC-1 and GPC-2 genes exhibited delayed senescence but normal anther dehiscence and fertility. These results indicate a functional divergence of the homologous wheat and rice NAC genes and suggest the need for separate studies of the function and targets of these transcription factors in wheat and rice.

Identification of endogenous small peptides involved in rice immunity through transcriptomics- and proteomics-based screening.

Project description:Small signalling peptides, generated from larger protein precursors, are important components to orchestrate various plant processes such as development and immune responses. However, small signalling peptides involved in plant immunity remain largely unknown. Here, we developed a pipeline using transcriptomics- and proteomics-based screening to identify putative precursors of small signalling peptides: small secreted proteins (SSPs) in rice, induced by rice blast fungus Magnaporthe oryzae and its elicitor, chitin. We identified 236 SSPs including members of two known small signalling peptide families, namely rapid alkalinization factors and phytosulfokines, as well as many other protein families that are known to be involved in immunity, such as proteinase inhibitors and pathogenesis-related protein families. We also isolated 52 unannotated SSPs and among them, we found one gene which we named immune response peptide (IRP) that appeared to encode the precursor of a small signalling peptide regulating rice immunity. In rice suspension cells, the expression of IRP was induced by bacterial peptidoglycan and fungal chitin. Overexpression of IRP enhanced the expression of a defence gene, PAL1 and induced the activation of the MAPKs in rice suspension cells. Moreover, the IRP protein level increased in suspension cell medium after chitin treatment. Collectively, we established a simple and efficient pipeline to discover SSP candidates that probably play important roles in rice immunity and identified 52 unannotated SSPs that may be useful for further elucidation of rice immunity. Our method can be applied to identify SSPs that are involved not only in immunity but also in other plant functions.

DNA Rearrangement in Orthologous Orp Regions of the Maize, Rice and Sorghum Genomes.

Project description:The homeologous Orp1 and Orp2 regions of maize and the orthologous regions in sorghum and rice were compared by generating sequence data for >486 kb of genomic DNA. At least three genic rearrangements differentiate the maize Orp1 and Orp2 segments, including an insertion of a single gene and two deletions that removed one gene each, while no genic rearrangements were detected in the maize Orp2 region relative to sorghum. Extended comparison of the orthologous Orp regions of sorghum and japonica rice uncovered numerous genic rearrangements and the presence of a transposon-rich region in rice. Only 11 of 27 genes (40%) are arranged in the same order and orientation between sorghum and rice. Of the 8 genes that are uniquely present in the sorghum region, 4 were found to have single-copy homologs in both rice and Arabidopsis, but none of these genes are located near each other, indicating frequent gene movement. Further comparison of the Orp segments from two rice subspecies, japonica and indica, revealed that the transposon-rich region is both an ancient and current hotspot for retrotransposon accumulation and genic rearrangement. We also identify unequal gene conversion as a mechanism for maize retrotransposon rearrangement.

OsNPR3.3-dependent salicylic acid signaling is involved in recessive gene xa5-mediated immunity to rice bacterial blight.

Project description:Salicylic acid (SA) is a key natural component that mediates local and systemic resistance to pathogens in many dicotyledonous species. However, its function is controversial in disease resistance in rice plants. Here, we show that the SA signaling is involved in both pathogen-associated-molecular-patterns triggered immunity (PTI) and effector triggered immunity (ETI) to Xanthomonas oryzae pv. Oryzae (Xoo) mediated by the recessive gene xa5, in which OsNPR3.3 plays an important role through interacting with TGAL11. Rice plants containing homozygous xa5 gene respond positively to exogenous SA, and their endogenous SA levels are also especially induced upon infection by the Xoo strain, PXO86. Depletion of endogenous SA can significantly attenuate plant resistance to PXO86, even to 86∆HrpXG (mutant PXO86 with a damaged type III secretion system). These results indicated that SA plays an important role in disease resistance in rice plants, which can be clouded by high levels of endogenous SA and the use of particular rice varieties.

Comparative transcriptomics enables the identification of functional orthologous genes involved in early leaf growth.

Project description:Leaf growth is a complex trait for which many similarities exist in different plant species, suggesting functional conservation of the underlying pathways. However, a global view of orthologous genes involved in leaf growth showing conserved expression in dicots and monocots is currently missing. Here, we present a genome-wide comparative transcriptome analysis between Arabidopsis and maize, identifying conserved biological processes and gene functions active during leaf growth. Despite the orthology complexity between these distantly related plants, 926 orthologous gene groups including 2829 Arabidopsis and 2974 maize genes with similar expression during leaf growth were found, indicating conservation of the underlying molecular networks. We found 65% of these genes to be involved in one-to-one orthology, whereas only 28.7% of the groups with divergent expression had one-to-one orthology. Within the pool of genes with conserved expression, 19 transcription factor families were identified, demonstrating expression conservation of regulators active during leaf growth. Additionally, 25 Arabidopsis and 25 maize putative targets of the TCP transcription factors with conserved expression were determined based on the presence of enriched transcription factor binding sites. Based on large-scale phenotypic data, we observed that genes with conserved expression have a higher probability to be involved in leaf growth and that leaf-related phenotypes are more frequently present for genes having orthologues between dicots and monocots than clade-specific genes. This study shows the power of integrating transcriptomic with orthology data to identify or select candidates for functional studies during leaf development in flowering plants.
