“…IWA4065 and IWA7401 SNP sequences correspond to the SWI/SNF complex subunit SWI3B, which is involved in the Jasmonate and ethylene pathways [70]. The IWA4451 SNP sequence corresponded to the galactose lectin protein domain, which participates in several plant abiotic stress tolerance mechanisms [73]. In addition, 11 markers were found to be linked with both Heat_ and PEG_RI ( Table 2).…”

Worldwide periods of heat and drought are projected to be more frequent, longer, and occurring earlier, which could deleteriously affect the productivity of cool-season crops including wheat (Triticum spp.). The coexistence of heat and drought stresses affects plant biochemical and physiological processes including cell membrane function. The increased permeability and leakage of ions out of the cell has been used as a measure of cell membrane stability (CMS) and as a screen test for stress tolerance. The main objectives of this research were to: (1) screen a global spring wheat panel for CMS by exposing leaf tissue to heat treatment and osmotic pressure (PEG 600), (2) identify potential quantitative trait loci (QTL)/genes linked with CMS using genome-wide association mapping, and (3) estimate the relationship between the field performance and measured CMS. The results indicated highly significant differences among the 2111 spring wheat accessions regarding CMS. Moreover, several SNPs were found to be significantly linked with CMS. The annotation of the significant SNPs indicated that most of these SNPs are linked with important functional genes, which control solute transport through the cell membrane and other plant biochemical activities related to abiotic stress tolerance. Overall, this study demonstrated the use of genome-wide association mapping for the identification of potentially new genomic regions associated with CMS. Tolerant genotypes identified in this study proved to be more productive under preliminary field stress conditions. Thus, the identified membrane-stable accessions could be used as parental genotypes in breeding programs for heat or drought stress tolerance.

Background and Aims The Nictaba family groups all proteins that show homology to Nictaba, the tobacco lectin. So far, Nictaba and an Arabidopsis thaliana homologue have been shown to be implicated in the plant stress response. The availability of more than 50 sequenced plant genomes provided the opportunity for a genome-wide identification of Nictaba-like genes in 15 species, representing members of the Fabaceae, Poaceae, Solanaceae, Musaceae, Arecaceae, Malvaceae and Rubiaceae. Additionally, phylogenetic relationships between the different species were explored. Furthermore, this study included domain organization analysis, searching for orthologous genes in the legume family and transcript profiling of the Nictaba-like lectin genes in soybean.Methods Using a combination of BLASTp, InterPro analysis and hidden Markov models, the genomes of Medicago truncatula, Cicer arietinum, Lotus japonicus, Glycine max, Cajanus cajan, Phaseolus vulgaris, Theobroma cacao, Solanum lycopersicum, Solanum tuberosum, Coffea canephora, Oryza sativa, Zea mays, Sorghum bicolor, Musa acuminata and Elaeis guineensis were searched for Nictaba-like genes. Phylogenetic analysis was performed using RAxML and additional protein domains in the Nictaba-like sequences were identified using InterPro. Expression analysis of the soybean Nictaba-like genes was investigated using microarray data.Key Results Nictaba-like genes were identified in all studied species and analysis of the duplication events demonstrated that both tandem and segmental duplication contributed to the expansion of the Nictaba gene family in angiosperms. The single-domain Nictaba protein and the multi-domain F-box Nictaba architectures are ubiquitous among all analysed species and microarray analysis revealed differential expression patterns for all soybean Nictaba-like genes.Conclusions Taken together, the comparative genomics data contributes to our understanding of the Nictaba-like gene family in species for which the occurrence of Nictaba domains had not yet been investigated. Given the ubiquitous nature of these genes, they have probably acquired new functions over time and are expected to take on various roles in plant development and defence.

Second-generation biofuels "2G generally uses residues composed of lignocellulosic materials to produce renewable energy potentially up to 50% , without increasing the planted areas. However, the high cost of enzymes required for cell wall disassembly prior to the sacchariication makes the "2G production more expensive yet, compared to the irst-generation biofuels. Designing plants with less lignin, a barrier to "2G production, or facilitating cell wall disassembly by searching for the plant mechanisms can be the way to obtain "2G feasibility. Therewith, plant cell wall proteomics provides valuable information concerning the main cell wall proteins CWPs involved in its biosynthesis and rearrangements. Essentially, two plants of the grass family have been studied: sugarcane as a crop amenable to second-generation ethanol E2G production and Brachypodium distachyon as a model plant amenable to genetic transformation. Cell wall proteomics has allowed the identiication of numerous CWPs as well as their ine proiling in diferent organs and at various developmental stages. Proteins acting on carbohydrates, mostly glycosyl hydrolases, and oxidoreductases, including class III peroxidases and laccases, can be highlighted. "oth kinds of CWPs are assumed to contribute to the remodelling of cell wall polysaccharides by enzymatic or nonenzymatic mechanisms. CWPs present in growing organs could also be atractive candidates since they greatly contribute to cell wall plasticity.Keywords: Brachypodium distachyon, cell wall protein, grass, second generation ethanol, sugarcane © 2017 The Author(s).

IntroductionSecond-generation biofuels "2G are a promising renewable alternative to supply energy demand of fossil fuels worldwide, whose advantage is mostly due to the lower emission of greenhouse gases and the possibility to increase the production without widening the planted area. However, we are still far from producing "2G at an economically competitive way and reasonable amount to replace fossil fuels. "2G uses lignocellulosic material as substrates. Since sugarcane has been considered one of the best crops to produce bioethanol, its bagasse and straw have been studied as one of the main complementary sources of C 6 and C 5 sugars for "2G. One of the main constrains to its economic feasibility relies on the rate of success of the enzymatic sacchariication enabling the conversion of the plant cell wall sugars into bioethanol [1]. Sacchariication of the cell wall ...
