Horizontal gene transfer from bacteria and fungi as a driving force in the evolu- tion of plant parasitism in nematodes. Nematology 17:641 646. Kang, J. S., Choi, K. S., Shin, S. C., Moon, I. S., Lee, S. G. and Lee, S. H. 2004. Development of an efficient... We identified two novel expansin (EXP) genes in the expressed sequence tag database of Bursaphelenchus xylophilus, designated as Bx-EXPB2 and -EXPB3. Novel Bx-EXPBs encoded 150 amino acids and their similarities in coding sequence were 70.7?84.0% to the previously reported EXPB1 of B. xylophilus. Bx-EXPB2 and Bx-EXPB3 were clustered with Bx-EXPB1 and Bm- EXPB1, respectively, forming the independent phylogeny with other nematode EXPs. All identified Bx-EXPBs contained the signal peptide and were... -

The central purpose of this paper has been to provide a conceptual model that is capable of supporting the development of appropriate early childhood practices for the 21st Century. A strong consensus has emerged regarding the importance of devel- oping Communication, Collaboration and Creativity during the early years. The paper argues that these three principles are related to each other very closely at the level of theory and in some of the very best early childhood education practice. It is... -

the identification of three clusters of issues: (1) data and computational issues, (2) personal tastes and recommendation issues, and (3) recommendation algorithms and digital platforms issues. These issues were used to structure the final version of the educational activity. Cluster 1: Data and Computational Issues The participants repeatedly faced difficulties in interpreting the data and... Recommendation algorithms play an important role in the current media landscape by fostering interactions between users of digital media platforms and media content. The growing concern with recommendation algorithms raises important questions for media educators who emphasize critical analysis of media content and creative production and are required to develop media education initiatives focused on a critical understanding of digital platforms and their underlying technical infrastructures.... -

genes, and the phenotype of tumor cells in acidic environments may be dependent on patterns of gene expression. Thus, better under- standing of acidity-mediated gene regulation may facilitate the identification of effective therapeutic strategies for gastric cancers exposed to acidic conditions. In this study, we selected several genes involved in regulation of the cell cycle, cell viability,... an acidic environment altered the expression of atg5, HSPA1B, collagen XIII , collagen XXAI , slug, snail , and zeb1 genes which are related to regulation of cell resistance to cytotoxicity and malignancy, and as expected, resulted in increased resistance of cells to multiple chemotherapeutic drugs including etoposide, doxorubicin, daunorubicin, cisplatin, oxaliplatin and 5-FU. Interestingly, however, acidic environment dramatically sensitized GC cells to apoptosis induced by tumor necrosis... -

spike culture method is simple, rapid, environment-independent, and is less resource demanding in terms of time and labour compared to field-based screening (Huang et al., 2020). To further support the validity of the immature spike culture screening method for FHB disease severity assessment and resistance identification, the objectives of this study were to (1) assess FHB severity in M 4... Fusarium head blight (FHB) is a devastating fungal disease of wheat (Triticum aestivum L.). The lack of genetic resources with stable FHB resistance combined with a reliable and rapid screening method to evaluate FHB resistance is a major limitation to the development of FHB resistant wheat germplasm. The present study utilized an immature wheat spike culture method to screen wheat spike culture derived variants (SCDV) for FHB resistance. Mycotoxin concentrations determined by liquid... -

spectroscopy (GC-MS) and headspace chromatography can be used to identify bioactive compounds in ginger EOs (Koch et al., 2017; Marriott et al., 2001). This approach will enable identification and outlining EOs components to assist in achieving the objectives of identifying those com- pounds responsible for antimicrobial efficacy (Bhattarai et al., 2018; Lopez et al., 2017). The EOs have... Essential oils (EOs) have gained a renewed interest in many disciplines such as plant disease control and medicine. This review discusses the components of ginger EOs, their mode of action, and their potential nanotechnology applications in controlling tropical plant diseases. Gas chromatography-mass spectroscopy (GC-MS), high-performance liquid chromatography, and headspace procedures are commonly used to detect and profile their chemical compositions EOs in ginger. The ginger EOs are composed... -

was placed on the Fusarium selective pentachloronitrobenzene medium (Nash and Synder, 1962) without surface sterilization, and incubated for 3-4 days. The species identification of the Fusarium isolates from rice straws were done using their nucleotide sequences of TEF-1α obtained as described above. Mycelial growth, conidiation, and perithecia produc- tion. Mycelial growth was evaluated on... Fusarium asiaticum of the F. graminearum species complex causes head blight in small-grain cereals. The nivalenol (NIV) chemotypes of F. asiaticum is more common than the deoxynivalenol (DON) chemotypes of F. asiaticum or F. graminearum in Korea. To understand the prevalence of F. asiaticum–NIV in Korean cereals, we characterized the biological traits of 80 cereal isolates of F. asiaticum producing NIV or 3-acetyl-deoxynivalenol (3-ADON), and 54 F. graminearum with 3-ADON or... -
Research Notes : Difference in Chemotype Composition of Fusarium graminearum Populations Isolated from Durum Wheat in Adjacent Areas Separated by the Apennines in Northern-Central Italy

graminearum chemotypes have been described: 3Ac-DON, 15Ac-DON and NIV. Chemotype identification is broadly used to characterize F. graminearum for its toxigenic potential (Pasquali et al., 2009). There was a correlation between the presence of F. graminearum chemotype and wheat grain mycotoxin content. DON and NIV contents can be successfully predicted by quantifying the fungal biomass of DON and... Chemotype composition of Fusarium graminearum strains, isolated from durum wheat kernels from naturally FHB infected fields in Northern and Central Italy, was investigated by multiplex PCR. The different climatic and environmental conditions of the two examined areas separated by the Apennines affected the composition of chemotypes. 15Ac-DON chemotype was predominant in both the sub areas. Nivalneol chemotype was more frequent in the warmer sub area. -

to get comprehensive understanding about genetic diversity of fungal populations, it is time consuming and laborious. The analysis of TEF1 gene sequences in this study was able to provide the identification of lineage 6 isolates from other F. graminearum lineages, and it can be simply used for population studies as integrating other structural genes. A phylogenetic analysis within lineage 6 or 7,... We performed diagnostic PCR assays and a phylogenetic analysis using partial sequences of TEF1 (translation elongation factor-1) to determine the trichothecene chemotypes and genetic diversity of F. graminearum isolates from maize and rice samples collected in 2009 in Korea. PCR using a species-specific primer set revealed a total of 324 isolates belonging to the putative F. graminearum species complex. PCR with trichothecene chemotypespecific primers revealed that the nivalenol (NIV) chemotype... -
