Abstract
Soil salinity and saline irrigation water are major constraints in sugarcane affecting the production of cane and sugar yield. To understand the salinity induced responses and to identify novel genomic resources, integrated de novo transcriptome and small RNA sequencing in sugarcane wild relative, Erianthus arundinaceus salt tolerant accession IND 99-907 and salt-sensitive sugarcane genotype Co 97010 were performed. A total of 362 known miRNAs belonging to 62 families and 353 miRNAs belonging to 63 families were abundant in IND 99-907 and Co 97010 respectively. The miRNA families such as miR156, miR160, miR166, miR167, miR169, miR171, miR395, miR399, miR437 and miR5568 were the most abundant with more than ten members in both genotypes. The differential expression analysis of miRNA reveals that 221 known miRNAs belonging to 48 families and 130 known miRNAs belonging to 42 families were differentially expressed in IND 99-907 and Co 97010 respectively. A total of 12,693 and 7982 miRNA targets against the monoploid mosaic genome and a total of 15,031 and 12,152 miRNA targets against the de novo transcriptome were identified for differentially expressed known miRNAs of IND 99-907 and Co 97010 respectively. The gene ontology (GO) enrichment analysis of the miRNA targets revealed that 24, 12 and 14 enriched GO terms (FDR < 0.05) for biological process, molecular function and cellular component respectively. These miRNAs have many targets that associated in regulation of biotic and abiotic stresses. Thus, the genomic resources generated through this study are useful for sugarcane crop improvement through biotechnological and advanced breeding approaches.

Lv B, Hu K, Tian T, Wei K, Zhang F, Jia Y, Tian H, Ding Z. The pre-mRNA splicing factor RDM16 regulates root stem cell maintenance in Arabidopsis. JOURNAL OF INTEGRATIVE PLANT BIOLOGY 2021; 63:662-678. [PMID: 32790237 DOI: 10.1111/jipb.13006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 07/29/2020] [Indexed: 06/11/2023]
Abstract
Pre-mRNA (messenger RNA) splicing participates in the regulation of numerous biological processes in plants. For example, alternative splicing shapes transcriptomic responses to abiotic and biotic stress, and controls developmental programs. However, no study has revealed a role for splicing in maintaining the root stem cell niche. Here, a screen for defects in root growth in Arabidopsis thaliana identified an ethyl methane sulfonate mutant defective in pre-mRNA splicing (rdm16-4). The rdm16-4 mutant displays a short-root phenotype resulting from fewer cells in the root apical meristem. The PLETHORA1 (PLT1) and PLT2 transcription factor genes are important for root development and were alternatively spliced in rdm16-4 mutants, resulting in a disordered root stem cell niche and retarded root growth. The root cap of rdm16-4 contained reduced levels of cytokinins, which promote differentiation in the developing root. This reduction was associated with the alternative splicing of genes encoding cytokinin signaling factors, such as ARABIDOPSIS HISTIDINE PHOSPHOTRANSFER PROTEIN5 and ARABIDOPSIS RESPONSE REGULATORS (ARR1, ARR2, and ARR11). Furthermore, expression of the full-length coding sequence of ARR1 or exogenous cytokinin application partially rescued the short-root phenotype of rdm16-4. This reveals that the RDM16-mediated alternative splicing of cytokinin signaling components contributes to root growth.

The novel cyst nematode effector protein 30D08 targets host nuclear functions to alter gene expression in feeding sites. THE NEW PHYTOLOGIST 2018; 219:697-713.

Abstract
Cyst nematodes deliver effector proteins into host cells to manipulate cellular processes and establish a metabolically hyperactive feeding site. The novel 30D08 effector protein is produced in the dorsal gland of parasitic juveniles, but its function has remained unknown. We demonstrate that expression of 30D08 contributes to nematode parasitism, the protein is packaged into secretory granules and it is targeted to the plant nucleus where it interacts with SMU2 (homolog of suppressor of mec-8 and unc-52 2), an auxiliary spliceosomal protein. We show that SMU2 is expressed in feeding sites and an smu2 mutant is less susceptible to nematode infection. In Arabidopsis expressing 30D08 under the SMU2 promoter, several genes were found to be alternatively spliced and the most abundant functional classes represented among differentially expressed genes were involved in RNA processing, transcription and binding, as well as in development, and hormone and secondary metabolism, representing key cellular processes known to be important for feeding site formation. In conclusion, we demonstrated that the 30D08 effector is secreted from the nematode and targeted to the plant nucleus where its interaction with a host auxiliary spliceosomal protein may alter the pre-mRNA splicing and expression of a subset of genes important for feeding site formation.

JOURNAL OF FISH BIOLOGY 2018; 92:1505-1525.

Abstract
Eleven single nucleotide polymorphisms (SNP) in Ctenopharyngodon idella toll-like receptor 7 (citlr7) gene, containing two in the 5'-flanking region, three within the single intron and six distributed in the coding sequence (CDS), were identified. A case-control study of 73 susceptible individuals and 67 resistant individuals was conducted to test the SNPs-based susceptibility-resistance association and mRNA expression of citlr7 to grass carp reovirus (GCRV), showing that both 820 A/G and 1726 A/G were significantly correlative sites in genotype (P < 0·05). Multifactor dimensionality reduction (MDR) analysis suggested the exertion of antiviral effects of 820 A/G might rely on SNPs interactions of citlr7 and C. idella toll-like receptor 8 (citlr8). Combining the mortality rate and citlr7 mRNA expression, it was suggested that 1726 GG-genotyped individuals might be more resistant than 1726 A/G genotyped individuals, indicating the selection on synonymous mutations in 1726 A/G might be susceptibility-resistance-type specific. In addition, haplotype analysis uncovered no significantly correlative haplotypes in citlr7. These findings may provide an in-depth insight for the further functional research of citlr7. The potential genetic markers identified may contribute to the molecular and transgenic breeding of C. idella.

Abstract
This article contains data on RDM16 and STA1 regulate differential usage of exon/intron in RNA directed DNA Methylation pathway (RdDM) (Sharma et al., 2016) [5]. This data include expression profiles of top 100 genes that has at least one exon or intron differentially expressed in three different contrast, i.e., WT (Wild type) vs RDM16, WT vs STA1, and RDM16 vs STA1. Also we included the alignment of MORC6 protein to the ATPase-C family members that have conserved three ATP binding sites and conserved Mg2+ binding sites in the spliced exon.
