This research explores the complex relationships between water stress and the application of nitrogen fertilizer in two-row and six-row barley genotypes with the aim of comprehending their performance and mechanisms for responding to stress. The study was performed over two years, employing a randomized complete block design with varying irrigation levels, nitrogen treatments, and barley genotypes. The results showed significant differences in various agro-morphological, physiological and biochemical traits between the two-row and six-row barley genotypes under different conditions. Water stress led to significant decreases in grain yield, shoot dry weight, leaf area index, and relative water content across all genotypes. It also caused an increase in electrolyte leakage, malondialdehyde content, and hydrogen peroxide levels, indicative of cellular membrane damage and oxidative stress. However, antioxidant enzyme activities such as glutathione peroxidase, ascorbate peroxidase, and catalase, along with DPPH radical scavenging activity, escalated as a defense response. Furthermore, nitrogen fertilizer application generally enhanced grain yield and shoot dry weight while decreasing oxidative stress indicators. However, under water stress conditions, nitrogen application exacerbated the negative effects of water stress, leading to reduced crop yield and stress resistance. As a result, this study emphasizes the critical role of genotype selection and proper use of nitrogen fertilizer application in optimizing the performance of two-row and six-row barley crops under different humidity conditions.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"81 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141870941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While previous research has primarily focused on molecular mechanisms, acknowledging the significance of root architectural traits is essential. This study explores the development of the BC2F1 generation by crossing Zea diploperennis (donor) with maize inbred line LM13 (recurrent parent) to transfer water deficit tolerance attributes to maize. Efforts to develop backcross generations with Z. nicaraguensis were unsuccessful. The study investigates the response of wild maize relatives (Z. diploperennis and Z. nicaraguensis) and maize inbred line LM13 to WDS induced by osmolytes. Root trait modifications were analyzed using a root scanner, including parameters such as root projection area, length, tips, forks, segments, average root diameter, total root volume, number of metaxylem vessels, and xylem diameter. BC2F1 individuals, Z. diploperennis, and Z. nicaraguensis exhibited increased root projection area, total root length, and total root volume under WDS, while LM13 showed a decrease in most parameters. Scanning electron microscopy revealed increased metaxylem number in Z. diploperennis and BC2F1 under WDS, indicating drought tolerance. Z. nicaraguensis also displayed WDS tolerance. This study highlights the potential of wild maize relatives in conferring WDS tolerance and the feasibility of introgressing their root plasticity traits into cultivated maize for enhanced climatic resilience.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"34 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

QPM has notable variations in protein composition, critical amino acid profiles, and grain production potential. These variations significantly affect the nutritional value of our crops and the safety of the global food supply. For instance, QPM varieties can contain 60–100% more lysine and tryptophan than conventional maize. This increase in essential amino acids improves growth rates and health outcomes in populations relying on maize as a staple food. As we examine broad sense heritability estimates for these fundamental characteristics, it becomes clear that genetics significantly influences protein content. This means we can substantially increase the amount of protein in QPM through selective breeding. The essential amino acid composition, a defining feature of QPM, exhibits inheritable characteristics but with some fascinating complexities that call for more investigation. As a result of the complex trade-offs shown by the relationship between grain yield and these nutritional characteristics, we should consider comprehensive breeding approaches that consider several objectives. Genetic advance is an essential indicator of the efficiency of selection, and it gives us cause for hope. Within a relatively short period of generations, we may significantly improve the protein composition and the necessary amino acids. However, the intricate relationship between grain productivity and nutritional characteristics highlights the significance of comprehensive breeding programs that carefully maintain equilibrium between these objectives.In conclusion, this study provides helpful direction for upcoming research and breeding projects by synthesizing the state of the art about the genetic foundation of QPM. Understanding the dynamics of variability, heredity, and genetic advance with grain production, essential amino acid content, and protein content is vital to maximizing QPM's potential to address global food security.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"68 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aptamers as a promising alternative to antibodies were developed only against the gliadin fraction and its constituent immunogenic peptide. However, for accurate assessment of the immunogenic peptides in food products through aptamer-based detection methods, there is a scope for developing aptamers against celiac disease epitopes in glutenin fractions. Here we report the development of aptamer against the immunogenic peptide sequence GQGQQGYYPTSPQQ of high molecular weight glutenin having celiac disease epitope. The aptamer was selected using magnetic bead-based SELEX (Mag-SELEX) method and characterised by ITC and circular dichroism. ITC experiment reveals that the dissociation constant (Kd) of selected aptamer Apt_J91P for primary binding site is 2.26 μM, and for secondary binding site, it is 4.385 mM in aptamer binding buffer. The binding mechanism of the aptamer with target was found to be enthalpy and entropy driven. Circular dichroism experiments show that aptamer forms stem and loop secondary structure. The limit of detection (LOD) of aptamer calculated by direct-ELAA method was found to be 16.0875 µM. We conclude that aptamer Apt_J91P can be successfully used for detecting celiac disease epitopes in glutenin and further improvement/modification would help in the development of sensitive aptasensors.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"1 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to explore the effect of salt stress on nine barley genotypes of different North African origins. Plants were exposed to moderate (8 dS m−1) and high (12 dS m−1) salinity levels. At the reproductive stage, physiological, biochemical traits and yield components were measured. Our results revealed that genotypes substantially differed in their responses to moderate and severe salt stress conditions. The analysis of variance indicated highly significant effects of the salinity, origin, type, and their interactions. Interestingly, barley plants exposed to salt stress exhibited a high increase in shoot electrolyte leakage, Na+/K+ ratio, hydrogen peroxide, and Malondialdehyde contents. Moreover, salt-tolerant barley genotypes showed high osmo-protectant accumulation ability with increases in proline content, soluble sugars content, and proteins content under salinity compared to the control. A significant rise in antioxidant enzyme activities in shoots of all genotypes was recorded under both moderate and severe salinity levels, leading to varying growth responses among the genotypes subjected to salt stress. Furthermore, a stepwise regression revealed that under salinity stress conditions, hydrogen peroxide level was the most predominant trait and had the maximum effect on kernel weight and grain yield. As a consequence, the role of oxidative and osmotic homeostasis adjustment in preventing the formation of reactive oxygen species and in maintaining considerable yield rate sustain, water use efficiency, and uptake of essential ions balanced maintenance under salt stress is emphasized. This confers the ability to survive under stress conditions as a genetic source for developing salt-tolerant breeding programs.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"18 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141746111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starch synthase (SS) is a key regulator of starch metabolism. Among its five isoforms, SSIII plays a pivotal role in phytoglycogen accumulation. In wheat, it is associated with starch accumulation but is sensitive to heat stress. In silico characterization indicated two homologous copies of the TaSSIII genes (Triticum aestivum starch synthase III genes), TaSSIIIa and TaSSIIIb. TaSSIIIa shares maximum similarity with HvSSIIIa, whereas TaSSIIIb exhibits maximum similarity with OsSSIIIb. It encodes proteins with an N-terminal transit peptide, an SSIII specific domain, a C-terminal catalytic domain, and a conserved glycosyltransferase domain with variations among the homoeologs. The catalytic domain has N-glycosylation motifs, with different numbers in the two homologs. ADP glucose-binding motifs are present in the SS-CD and GT-1 domains. ADP-binding pockets are present at the C-terminus of the catalytic domains. Maximum heterogen ligands are found in TaSSIIIa1B and minimum in TaSSIIIb2B. TaSSIIIb is expressed in leaf, stem, root, spike, and grain, and in much higher amounts than TaSSIIIa. Pot-grown wheat genotypes showed heat stress-induced upregulation of the genes TaSSIIIa1D and TaSSIIIb2D in the flag leaf. The tolerant genotype showed a significantly higher fold increase in the transcript levels under heat stress. Under the stress in the field, transcript level change for TaSSIIIa1D was higher in peduncle as compared to flag leaf, and that of TaSSIIIb2D was not significantly different between tissues. Homoeologous copies of the gene have tissue and genotype-specific expression, are influenced by heat stress, and thus may play a role in the homeostasis of starch metabolism under stress.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"54 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141721329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, understanding the genetic basis of desirable alleles underpinning micronutrients is important for wheat biofortification. A diverse collection of 111 wheat genotypes was evaluated for two years to measure micronutrient concentrations such as iron (Fe), selenium (Se), and zinc (Zn). Our study showed significant natural phenotypic variation for all of the studied minerals underlying both years and genotype means with normal distribution. GWAS analysis revealed 303 significant single-nucleotide polymorphisms (SNPs) that were associated with all micronutrients in the wheat panel. Highly significant markers were detected to be near several potential candidate genes that have crucial roles in enhanced mineral accumulation in wheat grains. Markedly, the gene TraesCS1A02G402400 that mapped on chromosome 1A was annotated as a mitogen-activated protein kinase (MAPKs) that was revealed to control the variation of the grain contents of Zn and Fe. Understanding the role of MAPKs in mineral accumulation offers potential pathways for enhancing the nutritional quality of wheat through biofortification. In conclusion, advances in genomic technologies and a deeper understanding of the genetic mechanisms underlying mineral accumulation are paving the way for the development of wheat cultivars with improved nutritional qualities, contributing to the alleviation of micronutrient deficiencies worldwide.","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"18 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
