    Genome-wide identification of salinity responsive HSP70s in common bean
    (Springer, 2016) Buyuk, Ilker; Inal, Behcet; Ilhan, Emre; Tanriseven, Mehmet; Aras, Sumer; Erayman, Mustafa
    The present study is aimed to identify and characterize HSP70 (PvHSP70) genes in two different common bean cultivars under salt stress. For this purpose various in silico methods such as RNAseq data and qRT-PCR analysis were used. A total of 24 candidate PvHSP70 gene were identified. Except for chromosome 4 and 7, these candidate PvHSP70 genes were distributed on the remaining chromosomes. While the lowest number of PvHSP70 genes was determined on chromosomes 1, 3, 5, 7, 9, 10 and 11 (one HSP70 gene), the highest number of PvHSP70s was on chromosomes 6 and 8 (seven HSP70 genes each). Three genes; PvHSP70-5, -9, and -10 were found to have no-introns. In addition, four tandemly and six segmentally duplicated gene couples were detected. A total of 13 PvHSP70 genes were targeted by miRNAs of 44 plant species and the most targeted genes were PvHSP70-5 and -23. The expression profile of PvHSP70 genes based on publicly available RNA-seq data was identified and salt treated leaf tissue was found to have more gene expression levels compared to the root. qRT-PCR analysis showed that the transcript concentrations of upregulated PvHSP70 genes in leaves of Zulbiye (sensitive) were mostly higher than those of Yakutiye (resistant). The present study revealed that PvHSP70 genes might play an important role in salt stress response for common bean cultivars and variability between cultivars also suggests that these genes could be used as functional markers for salt tolerance in common bean.

    Transcriptome analysis of wheat inoculated with Fusarium graminearum
    (Frontiers Media Sa, 2015) Erayman, Mustafa; Turktas, Mine; Akdogan, Guray; Gurkok, Tugba; Inal, Behcet; Ishakoglu, Emre; Ilhan, Emre
    Plants are frequently exposed to microorganisms like fungi, bacteria, and viruses that cause biotic stresses. Fusarium head blight (FHB) is an economically risky wheat disease, which occurs upon Fusarium graminearum (Fg) infection. Moderately susceptible (cv. Mizrak 98) and susceptible (cv. Gun 91) winter type bread wheat cultivars were subjected to transcriptional profiling after exposure to Fg infection. To examine the early response to the pathogen in wheat, we measured gene expression alterations in mock and pathogen inoculated root crown of moderately susceptible (MS) and susceptible cultivars at 12 hours after inoculation (hai) using 12X135K microarray chip. The transcriptome analyses revealed that out of 39,179 transcripts, 3668 genes in microarray were significantly regulated at least in one time comparison. The majority of differentially regulated transcripts were associated with disease response and the gene expression mechanism. When the cultivars were compared, a number of transcripts and expression alterations varied within the cultivars. Especially membrane related transcripts were detected as differentially expressed. Moreover, diverse transcription factors showed significant fold change values among the cultivars. This study presented new insights to understand the early response of selected cultivars to the Fg at 12 hai. Through the KEGG analysis, we observed that the most altered transcripts were associated with starch and sucrose metabolism and gluconeogenesis pathways.
