Genome-Wide Analysis of the Common Fig (Ficus carica L.) R2R3-MYB Genes Reveals Their Structure, Evolution, and Roles in Fruit Color Variation.

The R2R3-MYB transcription factor (TF) family is crucial for regulating plant growth, stress response, and fruit ripening. Although this TF family has been examined in a multitude of plants, the R2R3-MYB TFs in Ficus carica, a Mediterranean fruit species, have yet to be characterized. This study identified and classified 63 R2R3-MYB genes (FcMYB1 to FcMYB63) in the F.

Genome-wide analysis of gene family in the Mediterranean olive ( subsp. ) provides insight into structural patterns, evolution and functional diversity.

Plants regularly experience multiple abiotic and biotic pressures affecting their normal development. The 90-kDa heat shock protein (HSP90) plays a dynamic role in countering abiotic and biotic stresses via a plethora of functional mechanisms. The HSP90 has been investigated in many plant species.

Genome-wide identification, characterization, and evolutionary analysis of NBS-encoding resistance genes in barley.

In this study, a systematic analysis of Nucleotide-Binding Site (NBS) disease resistance () gene family in the barley, L. cv. Bowman, genome was performed.

Large-scale bioinformatic analysis of the regulation of the disease resistance NBS gene family by microRNAs in Poaceae.

In the present study, we have screened 71, 713, 525, 119 and 241 mature miRNA variants from Hordeum vulgare, Oryza sativa, Brachypodium distachyon, Triticum aestivum, and Sorghum bicolor, respectively, and classified them with respect to their conservation status and expression levels. These Poaceae non-redundant miRNA species (1,669) were distributed over a total of 625 MIR families, among which only 54 were conserved across two or more plant species, confirming the relatively recent evolutionary differentiation of miRNAs in grasses. On the other hand, we have used 257 H.

Large-scale analysis of NBS domain-encoding resistance gene analogs in Triticeae.

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.

Full-genome identification and characterization of NBS-encoding disease resistance genes in wheat.

Host resistance is the most economical, effective and ecologically sustainable method of controlling diseases in crop plants. In bread wheat, despite the high number of resistance loci that have been cataloged to date, only few have been cloned, underlying the need for genomics-guided investigations capable of providing a prompt and acute knowledge on the identity of effective resistance genes that can be used in breeding programs. Proteins with a nucleotide-binding site (NBS) encoded by the major plant disease resistance (R) genes play an important role in the responses of plants to various pathogens.

Characterization of novel wheat NBS domain-containing sequences and their utilization, in silico, for genome-scale R-gene mining.

In crop improvement, the isolation, cloning and transfer of disease resistance genes (R-genes) is an ultimate goal usually starting from tentative R-gene analogs (RGAs) that are identified on the basis of their structure. For bread wheat, recent advances in genome sequencing are supporting the efforts of wheat geneticists worldwide. Among wheat R-genes, nucleotide-binding site (NBS)-encoding ones represent a major class.

Development of new polymorphic microsatellite loci for the barley stem gall midge, Mayetiola hordei (Diptera: Cecidomyiidae) from an enriched library.

Using an enriched library method, seven polymorphic microsatellite loci were isolated from the barley stem gall midge, Mayetiola hordei. Polymorphism at loci was surveyed on 57 individual midges collected on barley in Tunisia. Across loci, polymorphism ranged from two to six alleles per locus.
