Expression Analysis of Pyrenophora teres f. maculata-Responsive Loci in Hordeum vulgare BABT
Habachi-Houimli,Yosra; Cherif,Mejda; Gharsallah,Charfeddine; Sébéi,Abdennour; Makni,Mohamed; Bouktila,Dhia.
Abstract Pyrenophora teres f. maculata is the causal agent of barley spot form net blotch (SFNB), a major stubble-borne disease in many barley-growing areas worldwide. In plants, the Nucleotide-Binding Site-Leucine-Rich Repeat (NBS-LRR) gene family functions in immunity against a variety of pathogens and pests. From a pre-established set of NBS-type resistance gene candidates, we have selected three candidate genes, HvNBS10, HvNBS72 and HvNBS85, to analyze their possible involvement in P. teres f. maculata resistance. The studied genes were mapped on chromosomes 5H and 7H. Expression profiles using qRT-PCR, 48 hours after infection by P. teres. f. maculata, revealed that the transcription of all genes acted in the same direction (down-regulation) in both...

Genetic Variability of the Tomato Leaf Miner (Tuta absoluta Meirick; Lepidoptera: Gelechiidae), in Tunisia, Inferred from RAPD-PCR Chilean J. Agric. Res.
Bettaibi,Asma; Mezghani-Khemakhem,Maha; Bouktila,Dhia; Makni,Hanem; Makni,Mohamed.
The tomato leaf miner Tuta absoluta Meyrick has invaded tomato (Solanum lycopersicum L.) crop in Tunisia since 2008 and is representing today a major threat to the production of this crop. In this study, we used the Randomly Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) technology to assess the genetic variability within and among seven populations of T. absoluta, collected on tomato from different regions in Tunisia. Using five RAPD-PCR primers and 108 individuals, 140 polymorphic fragments were recorded. From 335 different RAPD phenotypes generated, 71 were redundant and 264 unique to a specific population. The genetic structure of T. absoluta was investigated using analysis of molecular variance (AMOVA), genetic distances (Fst) and...

Hessian Fly, Mayetiola destructor (Say), Populations in the North of Tunisia: Virulence, Yield Loss Assessment and Phenological Data Chilean J. Agric. Res.
Makni,Hanem; Bouktila,Dhia; Mezghani,Maha; Makni,Mohamed.
Hessian fly, Mayetiola destructor (Say), is a destructive pest of wheat worldwide and an endemic pest in Tunisia. Two natural populations of this insect from the North of Tunisia were evaluated, in the field, for their virulence, based on response developed by bread wheat (Triticum aestivum L.) cultivars carrying H3, H5, H6, H7H8, H11, H13 and H16 resistance genes. H11, H13 and H16 showed a high effectiveness against both populations; therefore, their implication in Hessian fly breeding programs would be of interest. The level of infestation, as well as the yield loss, was assessed, based on the percentage of infested plants and variation in growth parameters due to infestation. The percentage of infested plants, over a 2-yr period in Mateur, averaged...

In Silico Identification of MicroRNAs with B/CYDV Gene Silencing Potential BABT
Bouallègue,Maryem; Bouktila,Dhia; Mezghani-Khemakhem,Maha; Capy,Pierre; Makni,Mohamed.
ABSTRACT Computational investigation of a set of publicly available plant microRNAs revealed 19 barley- and other plants-encoded miRNAs and their near-complement reverse sequences (miRNA*) that have potential to bind all B/CYDV open reading frames (ORFs) except ORF0 and ORF6. These miRNAs/miRNAs*, their binding positions and targets are discussed in the context of biological protection of cereals against B/CYDV, based on antiviral silencing.

Large-scale analysis of NBS domain-encoding resistance gene analogs in Triticeae Genet. Mol. Biol.
Bouktila,Dhia; Khalfallah,Yosra; Habachi-Houimli,Yosra; Mezghani-Khemakhem,Maha; Makni,Mohamed; Makni,Hanem.
Proteins containing nucleotide binding sites (NBS) encoded by plant resistance genes play an important role in the response of plants to a wide array of pathogens. In this paper, an in silico search was conducted in order to identify and characterize members of NBS-encoding gene family in the tribe of Triticeae. A final dataset of 199 sequences was obtained by four search methods. Motif analysis confirmed the general structural organization of the NBS domain in cereals, characterized by the presence of the six commonly conserved motifs: P-loop, RNBS-A, Kinase-2, Kinase-3a, RNBS-C and GLPL. We revealed the existence of 11 distinct distribution patterns of these motifs along the NBS domain. Four additional conserved motifs were shown to be significantly...
