Abstract Human selection has reshaped crop genomes. Here we report an apple genome variation map generated through sequencing of 117 diverse accessions. A comprehensive model speciation and domestication along the Silk Road is proposed based on evidence from genomic analyses. Cultivated apples likely originate Malus sieversii in Kazakhstan, followed by intensive introgressions M. sylvestris . Xinjiang China turns out to be “ancient” isolated ecotype not directly contributing domestication....
Both sorbitol and sucrose are imported into apple fruit from leaves. The metabolism of fuels growth development, accumulation sugars in is central to the edible quality apple. However, our understanding mechanisms controlling sugar remains quite limited. We identified members various gene families encoding key enzymes or transporters involved using homology searches comparison their expression patterns different tissues, analyzed relationship transcripts with enzyme activities during...
Abstract Domestication of the apple was mainly driven by interspecific hybridization. In present study, we report haplotype-resolved genomes cultivated ( Malus domestica cv. Gala) and its two major wild progenitors, M. sieversii sylvestris . Substantial variations are identified between haplotypes each genome. Inference genome ancestry identifies ~23% Gala as hybrid origin. Deep sequencing 91 accessions selective sweeps in apples that originated from either progenitors associated with...
Tonoplast transporters, including proton pumps and secondary are essential for plant cell function quality formation of fleshy fruits ornamentals. Vacuolar transport anthocyanins, malate, other metabolites is directly or indirectly dependent on the H+-pumping activities vacuolar H+-ATPase (VHA) and/or H+-pyrophosphatase, but how these regulated in modulating largely unknown. Here, we report a transcription factor, MdMYB1, apples that binds to promoters two genes encoding B subunits VHA,...
Melatonin has an important anti-aging role in plant physiology. We tested the effects of long-term melatonin exposure on metabolic status and protein degradation during natural leaf senescence trees Malus hupehensis Rehd. The 2-month regular supplement 100 μm to soil once every 6 days altered delayed degradation. For example, leaves from treated plants had significantly higher photosynthetic activity, chlorophyll concentrations, levels three end products (sorbitol, sucrose, starch) when...
Both sorbitol and sucrose are synthesized in source leaves transported to fruit for supporting growth tree species of the Rosaceae family. In apple (Malus domestica), antisense suppression aldose-6-phosphate reductase, key enzyme synthesis, significantly decreased concentration but increased leaves, leading a lower higher supply these plants. response this altered carbon supply, transgenic had much glucose similar levels fructose, sucrose, starch throughout development relative untransformed...
In plant-microbe interactions, plant sugars produced by photosynthesis are not only a carbon source for pathogens, but may also act as signals that modulate defense responses. Here, we report decreasing sorbitol synthesis in apple (Malus domestica) leaves antisense suppression of ALDOSE-6-PHOSPHATE REDUCTASE (A6PR) leads to downregulation 56 NUCLEOTIDE BINDING/LEUCINE-RICH REPEAT (NLR) genes and converts the phenotypic response Alternaria alternata from resistant susceptible. We identified...
Abstract Understanding the fruit developmental process is critical for quality improvement. Here, we report a comprehensive proteomic analysis of apple development over five growth stages, from young to maturity, coupled with metabolomic profiling. A tandem mass tag (TMT)-based comparative proteomics approach led identification and quantification 7098 6247 proteins, respectively. This large-scale dataset presents global view pathways involved in metabolism. When linked metabolomics data,...
Malic acid accumulation in the vacuole largely determines acidity and perception of sweetness apple. It has long been observed that reduction malate level is associated with increase ethylene production during ripening process climacteric fruits, but molecular mechanism linking to unclear. Here, we show ethylene-modulated WRKY transcription factor 31 (WRKY31)-Ethylene Response Factor 72 (ERF72)-ALUMINUM ACTIVATED MALATE TRANSPORTER 9 (Ma1) network regulates apple fruit. ERF72 binds promoter...
Abstract Carotenoids are essential for photosynthesis and photoprotection. Plants must evolve multifaceted regulatory mechanisms to control carotenoid biosynthesis. However, the regulators conserved among plant species remain elusive. Phytoene synthase (PSY) catalyzes highly regulated step of carotenogenesis geranylgeranyl diphosphate (GGPPS) acts as a hub interact with GGPP-utilizing enzymes synthesis specific downstream isoprenoids. Here, we report function Nudix hydrolase 23 (NUDX23),...
Abstract Vacuolar malic acid accumulation largely determines fruit acidity, a key trait for the taste and flavor of apple other fleshy fruits. Aluminum‐activated malate transporter 9 ( ALMT9 / Ma1 ) underlies major genetic locus, Ma , acidity in apple, but how protein transports across tonoplast is unclear. Here, it shown that overexpression coding sequence Ma1α drastically decreases “Royal Gala” leading to uncovering alternative splicing underpins Ma1's function. Alternative generates two...
MYB transcription factors have been linked to anthocyanin synthesis and various color phenotypes in plants. In apple, MYB10 confers a red-flesh phenotype due minisatellite insertion its R
Based on the curvilinear relationship between leaf nitrogen content and initial slope of response CO(2) assimilation (A:) to intercellular concentrations (C:(i)) in apple, it is hypothesized that Rubisco activation state decreases with increasing N this decreased accounts for assimilation. A range (1.0-5.0 g m(-2)) was achieved by fertilizing bench-grafted Fuji/M.26 apple (Malus domestica Borkh.) trees 45 d different concentrations, using a modified Hoagland's solution. Analysis A:/C:(i)...
In spring, nitrogen (N) uptake by apple roots begins about 3 weeks after bud break. We used 1-year-old 'Fuji' Malus domestica Borkh on M26 bare-root trees to determine whether the onset of N in spring is dependent solely growth stage plant or a function soil temperature. Five times during early season growth, and total amino acid concentration were measured growing at aboveground day/night temperatures 23/15 °C belowground 8, 12, 16 20 °C. 15NH415NO3 measure rate found that both...
Bench-grafted Fuji/M.26 apple (Malus domestica Borkh.) trees were fertilized with a nutrient solution (fertigation) containing 0, 2.5, 5, 7.5, 10, 15 or 20 mM nitrogen (N) in modified Hoagland's from June 30 to September 1. In mid-October, half of the each N treatment sprayed twice 3% urea, 1 week apart. The remaining served as controls. All harvested after leaf fall and stored at 2 °C over winter. One group was destructively sampled before bud break determine amounts reserve total...
Grapes are rich in phytochemicals with many proven health benefits. Phenolic profiles, antioxidant and antiproliferative activities of twenty-four selected Vitis vinifera grape cultivars were investigated this study. Large ranges variation found these for the contents total phenolics (95.3 to 686.5 mg/100 g) flavonoids (94.7 1055 (oxygen radical absorbance capacity 378.7 3386.0 mg Trolox equivalents/100 g peroxylradical scavenging capacity14.2 557 vitamin C g), cellular (3.9 139.9 µmol...
