The availability of well-assembled genome sequences and reduced sequencing costs have enabled the resequencing many additional accessions in several crops, thus facilitating rapid discovery development simple sequence repeat (SSR) markers. Although inbred spinach line Sp75 is available, previous efforts resulted a limited number useful SSR Identification polymorphic markers will support genetics breeding research spinach. This study aimed to use available genomic resources mine catalog large...
Abstract We report here that disruption of function the ω-3 FATTY ACID DESATURASE7 (FAD7) enhances plant defenses against aphids. The suppressor prosystemin-mediated responses2 (spr2) mutation in tomato (Solanum lycopersicum), which eliminates FAD7, reduces settling behavior, survival, and fecundity potato aphid (Macrosiphum euphorbiae). Likewise, antisense suppression LeFAD 7 expression wild-type plants infestations. Aphid resistance spr2 mutant is associated with enhanced levels salicylic...
Abstract A major bottleneck in identifying therapies to control citrus greening and other devastating plant diseases caused by fastidious pathogens is our inability culture the defined media or axenic cultures. As such, conventional approaches for antimicrobial evaluation (genetic chemical) rely on time-consuming, low-throughput inherently variable whole-plant assays. Here, we report that hairy roots support growth of like Candidatus Liberibacter spp., presumptive causal agents greening,...
White rust, caused by Albugo occidentalis, is one of the major yield-limiting diseases spinach (Spinacia oleracea) in some commercial production areas, particularly southern Texas United States. The use host resistance most economical and environment-friendly approach to managing white rust production. objectives this study were conduct a genome-wide associating (GWAS), identify single nucleotide polymorphism (SNP) markers associated with spinach, perform genomic prediction (GP) estimate...
Ethylene response factors (ERFs) comprise a large family of transcription that regulate numerous biological processes including growth, development, and to environmental stresses. Here, we report Pti5, an ERF in tomato [Solanum lycopersicum (Linnaeus)] was transcriptionally upregulated the potato aphid Macrosiphum euphorbiae (Thomas), contributed plant defences limited population growth this phloem-feeding insect. Virus-induced gene silencing Pti5 enhanced on tomato, both aphid-susceptible...
Plant α-dioxygenases (α-DOX) are fatty acid-hydroperoxidases that contribute to the synthesis of oxylipins, a diverse group compounds primarily generated through oxidation linoleic (LA) and linolenic acid (LNA). Oxylipins implicated in plant signaling against biotic abiotic stresses. We report here potato aphid (Macrosiphum euphorbiae) induces Slα-DOX1 but not Slα-DOX2 expression tomato (Solanum lycopersicum). upregulation by aphids does require either jasmonic (JA) or salicylic (SA)...
Yield prediction and variety selection are critical components for assessing production performance in breeding programs precision agriculture. Since plants integrate their genetics, surrounding environments, management conditions, crop phenotypes have been measured over cropping seasons to represent the traits of varieties. These days, UAS (unmanned aircraft system) provides a new opportunity collect high-quality images generate reliable phenotypic data efficiently. Here, we propose...
The efficient acquisition and transport of nutrients by plants largely depend on the root architecture. Due to absence complex microbial network interactions soil heterogeneity in a restricted soilless medium, architecture roots is function genetics defined matrix exogenously supplied such as nitrogen (N). knowledge trait combinations that offer optimal use efficiency (NUE) far from being conclusive. objective this study was define trait(s) best predicts correlates with vegetative biomass...
High-throughput imaging and genomic information can be combined to optimize marker development. Genome-wide association studies identified loci associated with plant growth traits. We candidate genes Despite advances in sequencing for genotyping, the lack of rapid, accurate, reproducible phenotyping platforms has hampered efforts use genetic analysis predict traits interest. Therefore, high-throughput systems phenotype related crop growth, yield, quality, resistance biotic abiotic stresses...
Abstract BACKGROUND Polyphenol oxidase (PPO) and peroxidase (POD) are key enzymes associated with shelf life defense responses. Thus, the activity of PPO POD is usually assessed to check quality food samples understand physiological responses plants different stresses. However, outcomes assessment studies highly dependent on assay conditions. Hence, in this study, we initially optimized extraction high‐throughput 96‐well plates‐based enzymatic methods evaluate inhibitory potential tomato...
Abstract Grafting with vigorous rootstocks could offer tomato growers in Texas sustainable and efficient option to achieve reliable yield across a range of production systems locations. Genotypes (G) grafted non-grafted were grown different environments (E) the 2017 2018 spring seasons. The objectives study (i) evaluate effects system grafting on traits, (ii) determine size genotypic genotype by environment interaction (G × E) variance components, (iii) relative stability tested genotypes...
Several high-throughput molecular genetic analyses rely on high-quality genomic DNA. Copurification of other molecules can negatively impact the functionality plant DNA preparations employed in these procedures. Isolating from agronomically important crops, such as sugarcane, rice, citrus, potato and tomato is a challenge due to presence high fiber, polysaccharides, or secondary metabolites. We present simplified, rapid reproducible SDS-based method that provides -quantity small amounts leaf...
Fatty acid desaturases (FADs) in plants influence levels of susceptibility to multiple stresses, including insect infestations. In this study, populations the green peach aphid (Myzus persicae) on Arabidopsis thaliana were reduced by mutations three desaturases: AtFAB2/SSI2, which encodes a chloroplastic stearoyl-[acyl-carrier-protein] 9-desaturase, and AtFAD7 or AtFAD3, encode ω-3 FADs chloroplast endoplasmic reticulum (ER), respectively. These data indicate that certain promote aphids are...
Abstract The Mi‐1.2 gene in tomato, Solanum lycopersicum L. (Solanaceae), confers resistance against several herbivores, including the potato aphid, Macrosiphum euphorbiae (Thomas) (Hemiptera: Sternorrhyncha: Aphididae) and sweetpotato whitefly, Bemisia tabaci (Gennadius) Aleyrodidae). Previous studies on tissue localization of have given varying results; whitefly was attributed to factors localized mesophyll or epidermis, whereas aphid phloem. Our study utilizes direct current electrical...
Predictive modeling (PM) is a useful tool in selecting from large number of target variables. Given the quantities data types generated unmanned aerial system (UAS) platforms, uncovering most appropriate candidate UAS data–based phenotype (UASDP) with strong relationship to crop traits may be challenge traditional regression models. We hypothesized that by employing machine learning techniques, contributions multiple vegetative indices as predictors biomass and water-use could defined...
Ascorbic acid (AsA), or vitamin C, is an essential nutrient for humans. In plants, AsA functions as antioxidant during normal metabolism in response to stress. Spinach a highly nutritious green leafy vegetable that consumed fresh, cooked part of other dishes. One current goal spinach breeding programs enhance quality and nutritional content. However, little known about the diversity content present germplasm, especially this study, worldwide panel 352 accessions was screened showing...
Abstract The tomato-potato psyllid (TPP), Bactericera cockerelli , is a vector for the phloem-limited bacterium Candidatus Liberibacter solanacearum (Lso), causative agent of economically important diseases including tomato vein-greening and potato zebra chip. Here, we screened 11 wild relatives TPP resistance as potential resources ( Solanum lycopersicum ) cultivar development. Six accessions with strong (survival <10%) were identified within S. habrochaites pennelli huaylasense...
Abstract Anthracnose ( Colletotrichum dematium ) is an important disease in spinach Spinacia oleracea ). Sources of resistance must be identified, and molecular tools developed to expedite cultivar development. In this study, a diverse collection 276 accessions was scored for anthracnose severity. We then evaluated marker identification approaches by testing how well haplotype‐based trait modelling compares single markers identifying strong association signals. Alleles linkage disequilibrium...
