Abstract Leaf spot disease was observed in sesame (Sesamum indicum L.) during 2009 and 2010 in Korea. The pathogen was identified as Alternaria simsimi based on morphological and cultural characteristics. The morphological identification was well supported by phylogenetic analysis of the ribosomal DNA-internal transcribed spacer region. A. simsimi isolates caused spot symptoms on leaves and stems of sesame plants 2 wk after artificial inoculation, which were similar to those observed in the…

Biological features and cultivation of sesame (a review)
Sesame is an ancient oilseed crop grown throughout the arid and subarid climates. Sesame oil has a good taste and is appreciated for its beneficial properties. The genus Sesamum L. (Pedaliaceae
Controlling Alternaria cerealis MT808477 Tomato Phytopathogen by Trichoderma harzianum and Tracking the Plant Physiological Changes
Results showed that the biological control process activates the defense cell strategies by increasing the plant tolerance, and activation of plant defense systems, and represents a safe and effective solution to phytopathogens that decreases plant cell stress by stimulating various defensive agents.

Analysis of mandipropamid residual levels through systematic method optimization against the matrix complexity of sesame leaves using HPLC/UVD.
This method was applied to field-treated samples collected from two different areas, Gwangju and Muan, in the Republic of Korea and the half-lives were similar, 5.10 and 5.41 days, respectively.


Taxonomy and pathogenicity of four seed-borne species of Alternaria from sesame
Based on the original descriptions and the isolates studied it is concluded that A. sesami and A.sesamicola are two distinct species.
Novel dematiaceous hyphomycetes
Novel taxa are described as Alternaria simsimi isolated from Sesamum indicum, distinguishing it from Alternaria sesami; Embellisia lolii from Lolium perenne, Nimbya perpunctulata from Alternanthera philoxeroides, and Stemphylium symphyti from Symphytum × uplandicum.
Alternaria redefined
The aim of this study was to delineate phylogenetic lineages within Alternaria and allied genera based on nucleotide sequence data of parts of the 18S nrDNA, 28S nRDNA, ITS, GAPDH, RPB2 and TEF1-alpha gene regions, and reveal a Pleospora/Stemphylium clade sister to Embellisia annulata, and a well-supported Alternaria clade.
Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics
The nuclear small-subunit rDNA sequences (16S-like) evolve rela­ tively slowly and are useful for studying distantly related organisms, whereas the mitochondrial rRNA genes evolve more rapidly and can be useful at the ordinal or family level.
