Agrobacterium rhizogenes (or Rhizobium rhizogenes) is able to transform plant genomes and induce the production of hairy roots. We describe use A. in tomato (Solanum spp.) rapidly assess gene expression function. Gene reporters indistinguishable plants transformed by tumefaciens as compared with rhizogenes. A root cell type- tissue-specific promoter resource has been generated for domesticated wild lycopersicum Solanum pennellii, respectively) using these approaches. Imaging roots coupled...
A genome scan was conducted in the North American Holstein-Friesian population for quantitative trait loci (QTL) affecting production and health traits using granddaughter design. Resource families consisted of 1,068 sons eight elite sires. Genome coverage estimated to be 2,551 cM (85%) 174 genotyped markers. Each marker tested effects on milk yield, fat protein percentage, somatic cell score, productive herd life analysis variance. Joint all identified 11 chromosomes that exceeded...
Elicitor recognition plays a key role in the reaction of plants to pathogens and induction plant defense responses. Furthermore, plant-microbe interactions involve numerous regulatory systems essential for against pathogens. Ethylene-inducing xylanase (Eix) is potent elicitor responses specific cultivars tobacco (Nicotiana tabacum) tomato (Solanum lycopersicum). The Eix receptors (LeEix1 LeEix2) belong superclade leucine-rich repeat receptor-like proteins (RLP) with signal receptor-mediated...
Evidence supports that sex determination (SD) in tilapia is controlled by major genetic factors may interact with minor as well environmental factors, thus implying SD should be analyzed a quantitative trait. Quantitative trait loci (QTL) for Oreochromis niloticus were previously detected on linkage groups (LG) 1 and 23. Twenty-one short single repeats (SSR) of >12 TGs one nucleotide polymorphism identified using the unpublished genome sequence LG23. All markers showed two segregating...
Abstract While the Arabidopsis (Arabidopsis thaliana) root has been elegantly characterized with respect to specification of cell identity, its development is missing a number cellular features present in other species. We have wild and domesticated tomato species, Solanum pennellii lycopersicum ‘M82.’ found extensive differences between these species for morphology including length, novel gravity set point angle, cortical layer patterning, stem niche structure, radial division. Using an...
Spatiotemporal regulation of transcription is fine-tuned at multiple levels, including chromatin compaction. Polycomb Repressive Complex 2 (PRC2) catalyzes the trimethylation Histone 3 lysine 27 (H3K27me3), which hallmark a repressive state. Multiple PRC2 complexes have been reported in Arabidopsis thaliana to control expression genes involved developmental transitions and maintenance organ identity. Here, we show that member display complex spatiotemporal gene patterns function root...
Methods for genomic prediction were evaluated an Israeli Holstein dairy population of 713,686 cows and 1,305 progeny-tested bulls with genotypes. Inclusion genotypes 343 elite in evaluation method that considers pedigree, phenotypes, simultaneously was also evaluated. Two data sets available: a complete set production records from 1985 through 2011, reduced after 2006 deleted. For each trait, multitrait animal model used to compute traditional genetic evaluations parities 1 3 as separate...
Summary Plants produce specialized metabolites to protect themselves from biotic enemies. Members of the Solanaceae family accumulate phenylpropanoid–polyamine conjugates (PPCs) in response attackers while also maintaining a chemical barrier steroidal glycoalkaloids (SGAs). Across plant kingdom, biosynthesis such defense compounds is promoted by jasmonate signaling which clade IIIe basic helix–loop–helix (bHLH) transcription factors play central role. By characterizing hairy root mutants...
Cuscuta species (dodders) are agriculturally destructive, parasitic angiosperms. These plants use haustoria as physiological bridges to extract nutrients and water from hosts. campestris has a broad host range wide geographical distribution. While some wild tomato relatives resistant, cultivated tomatoes generally susceptible C. infestations. However, specific Heinz (Solanum lycopersicum) hybrid cultivars exhibit resistance dodders in the field, but their defense mechanism was previously...
Challenging tomato or tobacco varieties with ethylene-inducing xylanase (EIX) from the fungus Trichoderma viride causes rapid induction of plant defence responses leading to programmed cell death. Using yeast two-hybrid system, we isolated a novel protein, small ubiquitin-related modifier protein (T-SUMO), which specifically interacts EIX. T-SUMO, cytoplasmic is member ubiquitin-like family. It shows homology human sentrin/SUMO1, suppresses tumour necrosis factor-induced Transgenic plants...
A population-wide linkage disequilibrium on bovine chromosome 14 between microsatellite ILSTS039 and DGAT1, a putative quantitative trait locus affecting milk production traits, was found in the Israeli Holstein population. total of 394 bulls were genotyped for both DGAT1 ILSTS039, 1747 cows ILSTS039. The allele termed "225," K (substitution lysine residue with alanine), associated decreased production, increased fat protein percent. number 225 alleles per individual same 80% genotyped. From...
Genetic markers in tilapia species associated with loci affecting sex determination (SD), sex-specific mortality or both were mapped to linkage groups (LG) 1, 2, 3, 6 and 23. The objective of this study was use these fine-map the locus greatest effect on SD Oreochromis niloticus. Our parental stock, full-sibs Nile (Swansea origin), divided into three groups: (i) untreated, (ii) feminized by diethylstilbestrol (iii) masculinized 17α-methyltestosterone. We analysed first group for association...
