Winter wheats require several weeks at low temperature to flower. This process, vernalization, is controlled mainly by the VRN1 gene. Using 6,190 gametes, we found be completely linked MADS-box genes AP1 and AGLG1 in a 0.03-centimorgan interval flanked Cysteine Cytochrome B5 . No additional were between last two 324-kb Triticum monococcum sequence or colinear regions rice sorghum. Wheat similar Arabidopsis meristem identity AGL2 , respectively. transcription was regulated vernalization both...
Rust resistance genes Lr37 , Sr38 and Yr17 are located within a segment of Triticum ventricosum (Tausch) Cess. chromosome 2NS translocated to the short arm bread wheat 2AS. Characterization this by 13 restriction fragment length polymorphism (RFLP) markers indicated that translocation replaced approximately half 2A (distal 25–38 centimorgans, cM). The objective study was develop polymerase chain reaction (PCR) assays based on RFLP marker cMWG682 facilitate transfer cluster rust into...
Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous class II present in a high number of conserved copies eukaryote genomes. An accurate identification these can help to shed light on the mechanisms controlling genome evolution and gene regulation. The structure distribution well-defined therefore computational approaches be used identify MITEs sequences. Here we describe MITE Tracker, novel, open source software program that finds classifies using an efficient...
The fungus Blumeria graminis f. sp. tritici causes wheat powdery mildew disease. Here, we study its spread and evolution by analyzing a global sample of 172 genomes. Our analyses show that B.g. emerged in the Fertile Crescent during domestication. After it throughout Eurasia, colonization brought to America, where hybridized with unknown grass species. Recent trade USA strains Japan, European China. In both places, they local ancestral strains. Thus, although spreads wind regionally, our...
Increasing wheat (Triticum aestivum L.) production is required to feed a growing human population. In order accomplish this task deeper understanding of the genetic structure cultivated wheats and detection genomic regions significantly associated with regulation important agronomic traits are necessary steps. To better understand basis relationships adaptation yield related traits, we used collection 102 Argentinean hexaploid cultivars genotyped 35k SNPs array, grown from two six years in...
Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat (Triticum aestivum L.), in Argentina.Host resistance the most economical, effective ecologically sustainable method controlling disease.Gene postulation helps to determine leaf rust genes (Lr genes) that may be present large group germplasm.Additionally presence Lr can determined using associated molecular markers.The objective this study was identify condition 66 cultivars from Argentina.Twenty...
New leaf rust resistance genes are needed in wheat ( Triticum aestivum L.) to provide additional sources of the highly variable and dynamic pathogen Puccinia triticina Eriks. Leaf gene Lr51 , located within a segment speltoides Taush chromosome 1S translocated long arm 1B bread wheat, is resistant current predominant races USA. The objectives this study were determine genetic length segment, develop PCR marker for use generate isogenic lines gene. Characterization two translocation (F‐7‐3...
ABSTRACT Nowadays in Argentina, cookies, crackers, and cakes are made of flour obtained from bread wheat with additives or enzymes that decrease the gluten strength but increase production costs. The present research work aims to study relationship between physicochemical composition (particle size average [PSA], protein, damaged starch [DS], water soluble pentosans [WSP], total [TP], gluten), alkaline retention capacities behavior, solvent profile (SRC) cookie‐making performance a set 51...
Cannabis sativa L. is a globally cultivated plant with significant industrial, nutritional, and medicinal value. Its genome, comprising nine autosomes sex chromosomes (X Y), has been extensively studied, particularly in the context of precise breeding for specific enduses. Recent advances have facilitated genome-wide analyses through platforms like NCBI Comparative Genome Viewer (CGV) CannabisGDB, among others, enabling comparative studies across multiple genotypes. Despite abundance genomic...
The identification of genetically homogeneous groups individuals is an ancient issue in population genetics and the case crops like wheat, it can be valuable information for breeding programs, genetic mapping germplasm resources. In this work we determined structure a set 102 Argentinean bread wheat (Triticum aestivum L.) elite cultivars using 38 biochemical molecular markers (functional, closely linked to genes neutral ones) distributed throughout 18 chromosomes. Genetic relationships among...
Abstract Background Plant miRNAs are a class of small non-coding RNAs that can repress gene expression at the post-transcriptional level by targeting RNA degradation or promoting translational repression. There is increasing evidence some derive from group non-autonomous II transposable elements called Miniature Inverted-repeat Transposable Elements (MITEs). Results We used public and degradome libraries Triticum aestivum to screen for microRNAs production predict their cleavage target...
The number and complexity of repetitive elements varies between species, being in general most represented those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis second generation DNA sequencing technologies provides a unique opportunity study portion each chromosome, enabling comparisons among them. Additionally, different approaches may produce depth insight repeatome content structure. In this work we analyze characterize sequences Triticum...
‘BIOINTA 2004’ (Reg. No. CV‐1030, PI 655312) is a hard red winter wheat ( Triticum aestivum L.) developed and released by the Marcos Juárez Experimental Station from National Wheat Breeding Program of Institute Agricultural Technology, Argentina. BIOINTA 2004, previously designated R4001, was selected for its excellent grain yield potential, resistance to leaf rust (caused Puccinia triticina Eriks.) conferred mainly Lr47 gene marker assisted selection (MAS), good bread‐making quality.
Survey sequencing of the bread wheat (Triticum aestivum L.) genome (AABBDD) has been approached through different strategies delivering important information. However, current sequence knowledge is not complete. The aim our study to provide and complementary set data for chromosome 4D. A survey was obtained by pyrosequencing flow-sorted 4DS (7.2×) 4DL (4.1×) arms. Single ends (SE) long mate pairs (LMP) reads were assembled into contigs (223 Mb) scaffolds (65 that aligned Aegilops tauschii...
