Downy mildew(DM),caused by obligate parasitic oomycetes,is a destructive disease for a wide range of crops *** outbreaks of impatiens downy mildew(IDM)in many countries have caused huge economic losses.A system to reveal plant–pathogen interactions in the early stage of infection and quickly assess resistance/susceptibility of plants to DM is *** this study,we established an early and rapid system to achieve these goals using impatiens as a ***-two cultivars of Impatiens walleriana and *** were evaluated for their responses to IDM at cotyledon,first/second pair of true leaf,and mature plant *** *** cultivars were highly susceptible to *** all *** cultivars were resistant to IDM starting at the first true leaf stage,many(14/16)were susceptible to IDM at the cotyledon *** cultivars showed resistance even at the cotyledon *** characterization showed that the resistance mechanism of the *** cultivars resembles that in grapevine and type II resistance in *** integrating full-length transcriptome sequencing(Iso-Seq)and RNA-Seq,we constructed the first reference transcriptome for Impatiens comprised of 48,758 sequences with an N50 length of 2060 *** transcriptome and qRT-PCR analyses revealed strong candidate genes for IDM resistance,including three resistance genes orthologous to the sunflower gene RGC203,a potential candidate associated with DM *** approach of integrating early disease-resistance phenotyping,histological characterization,and transcriptome analysis lay a solid foundation to improve DM resistance in impatiens and may provide a model for other crops.

Breeding crops for improved flavor is challenging due to the high cost of sensory evaluation and the difficulty of connecting sensory experience to chemical *** main goal of this study was to identify the chemical drivers of sweetness and consumer liking for fresh strawberries(Fragaria×ananassa).Fruit of 148 strawberry samples from cultivars and breeding selections were grown and harvested over seven years and were subjected to both sensory and chemical *** panel consisted of at least 100 consumers,resulting in more than 15,000 sensory data points per *** sugars,two acids and 113 volatile compounds were *** liking was highly associated with sweetness intensity,texture liking,and flavor intensity,but not sourness *** least square analyses revealed 20 volatile compounds that increased sweetness perception independently of sugars;18 volatiles that increased liking independently of sugars;and 15 volatile compounds that had positive effects on *** learning-based predictive models including sugars,acids,and volatiles explained at least 25%more variation in sweetness and liking than models accounting for sugars and acids *** compounds such asγ-dodecalactone;5-hepten-2-one,6-methyl;and multiple medium-chain fatty acid esters may serve as targets for breeding or quality control attributes for strawberry products.A genetic association study identified two loci controlling ester production,both on linkage group 6 ***-segregating makers in these regions can be used for increasing multiple esters *** study demonstrates a paradigm for improvement of fruit sweetness and flavor in which consumers drive the identification of the most important chemical targets,which in turn drives the discovery of genetic targets for marker-assisted breeding.
