“…Among defense-related genes, those encoding nucleotide-binding site leucine-rich repeat proteins were found to be less represented in the Musa sequence (89 genes) compared to Oryza sativa (464 genes) and Vitis vinifera (459 genes) (D'Hont et al 2012). In banana an extensive isolation of resistance genes has been done (Miller et al 2008;Peraza-echeverria et al 2008). PTI (pathogen-triggered immunity)-related genes like chitin elicitor-binding protein (CeBiP) and the chitin elicitor receptor kinase (CeRK1), important components of the plant signaling pathway that recognizes chitin oligosaccharide, are expressed more in resistant cultivar than susceptible against Foc TR4 (Li et al 2012).…”

“…In recent studies molecular markers were identified for banana classification (Wong et al 2002;Buhariwalla et al 2005;Santos et al 2005;Ruangsuttapha et al 2007;Swangpol et al 2007;Miller et al 2008), but the usefulness of these markers depends on (a) the distribution pattern of the markers on the chromosomes; (b) the genetic and structural location of these markers on conserved regions of different genomes; and (c) the possibility of chromosomal rearrangements between potential crossing parents in the chromosome regions of economically important traits (Pillay et al 2004). In order to determine small chromosomal rearrangements such as translocations and inversions or even the position of a smaller DNA sequence a more refined methodology based on single copy fluorescent in situ hybridization (FISH) is required.…”

The potential of high-resolution BAC-FISH in banana breeding

The genetic complexity in the genus Musa has been subject of study in many breeding programs worldwide. Parthenocarpy, female sterility, polyploidy in different cultivars and limited amount of genetic and genomic information make the production of new banana cultivars difficult and time consuming. In addition, it is known that part of the cultivars and related wild species in the genus contain numerous chromosomal rearrangements. In order to produce new cultivars more effectively breeders must better understand the genetic differences of the potential crossing parents for introgression hybridization, but extensive genetic information is lacking.As an alternative to achieve information on genetic collinearity we make use of modern chromosome map technology known as high-resolution fluorescent in situ hybridization (FISH). This article presents the technical aspects and applications of such a technology in Musa species. The technique deals with BAC clone positioning on pachytene chromosomes of Calcutta 4 (Musa acuminata ssp. burmanicoides, A genome group, section Eumusa) and M. velutina (section Rodochlamys). Pollen mother cells digestion with pectolytic enzymes and maceration with acetic acid were optimized for making cell spread preparations appropriate for FISH. As an example of this Euphytica (2009) 166:431-443 DOI 10.1007 approach we chose BAC clones that contain markers to known resistance genes and hybridize them for establishing their relative positions on the two species. Technical challenges for adapting existing protocols to the banana cells are presented. We also discuss how this technique can be instrumental for validating collinearity between potential crossing parents and how the method can be helpful in future mapping initiatives, and how this method allows identification of chromosomal rearrangements between related Musa species and cultivars.

“…CC-NBS-LRR-type proteins, the largest group of non-TIR-NBS-LRR proteins, can be found in both dicotyledons and monocotyledons. As with TNL, genome analyses of different plants (A. thaliana, Populus, Oryza sativa) have shown the remarkable structural diversification of this group [34]. In rice, genes encoding proteins with two NBS domains (CC-NBS-NBS-LRR) were identified [35].…”

Abstract:Plants are attacked by a wide spectrum of pathogens, being the targets of viruses, bacteria, fungi, protozoa, nematodes and insects. Over the course of their evolution, plants have developed numerous defense mechanisms including the chemical and physical barriers that are constitutive elements of plant cell responses locally and/or systemically. However, the modern approach in plant sciences focuses on the evolution and role of plant protein receptors corresponding to specific pathogen effectors. The recognition of an invader's molecules could be in most cases a prerequisite sine qua non for plant survival. Although the predicted three-dimensional structure of plant resistance proteins (R) is based on research on their animal homologs, advanced technologies in molecular biology and bioinformatics tools enable the investigation or prediction of interaction mechanisms for specific receptors with pathogen effectors. Most of the identified R proteins belong to the NBS-LRR family. The presence of other domains (including the TIR domain) apart from NBS and LRR is fundamental for the classification of R proteins into subclasses. Recently discovered additional domains (e.g. WRKY) of R proteins allowed the examination of their localization in plant cells and the role they play in signal transduction during the plant resistance response to biotic stress factors. This review focuses on the current state of knowledge about the NBS-LRR family of plant R proteins: their structure, function and evolution, and the role they play in plant innate immunity.
