| 1 | Localized bursting of mesocarp cells triggers catastrophic fruit cracking显示文摘The so-called rain-cracking of sweet cherry fruit severely threatens commercial production.Simple observation tells us that cuticular microcracking(invisible)always precedes skin macrocracking(visible).The objective here was to investigate how a macrocrack develops.Incubating detached sweet cherry fruit in deionized water induces microcracking.Incubating fruit in D2O and concurrent magnetic resonance imaging demonstrates that water penetration occurs only(principally)through the microcracks,with nondetectable amounts penetrating the intact cuticle.Optical coherence tomography of detached,whole fruit incubated in deionized water,allowed generation of virtual cross-sections through the zone of a developing macrocrack.Outer mesocarp cell volume increased before macrocracks developed but increased at a markedly higher rate thereafter.Little change in mesocarp cell volume occurred in a control zone distant from the crack.As water incubation continued,the cell volume in the crack zone decreased,indicating leaking/bursting of individual mesocarp cells.As incubation continued still longer,the crack propagated between cells both to form a long,deep macrocrack.Outer mesocarp cell turgor did not differ significantly before and after incubation between fruit with or without macrocracks;nor between cells within the crack zone and those in a control zone distant from the macrocrack.The cumulative frequency distribution of the logtransformed turgor pressure of a population of outer mesocarp cells reveals all cell turgor data followed a normal distribution.The results demonstrate that microcracks develop into macrocracks following the volume increase of a few outer mesocarp cells and is soon accompanied by cell bursting. | Eckhard Grimm Jan Hahn Daniel Pflugfelder Moritz Jonathan Schmidt Dagmar van Dusschoten Moritz Knoche | 2019 | Horticulture Research2019，6，1： | 5 |
| 2 | Transcriptional dynamics of the developing sweet cherry(Prunus avium L.)fruit:sequencing,annotation and expression profiling of exocarp-associated genes显示文摘The exocarp,or skin,of fleshy fruit is a specialized tissue that protects the fruit,attracts seed dispersing fruit eaters,and has large economical relevance for fruit quality.Development of the exocarp involves regulated activities of many genes.This research analyzed global gene expression in the exocarp of developing sweet cherry(Prunus avium L.,‘Regina’),a fruit crop species with little public genomic resources.A catalog of transcript models(contigs)representing expressed genes was constructed from de novo assembled short complementary DNA(cDNA)sequences generated from developing fruit between flowering and maturity at 14 time points.Expression levels in each sample were estimated for 34695 contigs from numbers of reads mapping to each contig.Contigs were annotated functionally based on BLAST,gene ontology and InterProScan analyses.Coregulated genes were detected using partitional clustering of expression patterns.The results are discussed with emphasis on genes putatively involved in cuticle deposition,cell wall metabolism and sugar transport.The high temporal resolution of the expression patterns presented here reveals finely tuned developmental specialization of individual members of gene families.Moreover,the de novo assembled sweet cherry fruit transcriptome with 7760 full-length protein coding sequences and over 20000 other,annotated cDNA sequences together with their developmental expression patterns is expected to accelerate molecular research on this important tree fruit crop. | Merianne Alkio Uwe Jonas Myriam Declercq Steven Van Nocker Moritz Knoche | 2014 | Horticulture Research2014，1，1： | 4 |
| 3 | 语言测试的因子结构探析:一项基于多样本CFA的历时研究显示文摘研究语言考试的因子结构对于考试的构念效度具有重要意义。尽管目前语言测试界关于考试因子结构的研究越来越多,但是很少有研究采用多次考试数据探讨语言考试的因子结构及结构的不变性。本研究采用纵向研究设计及多样本验证性因子分析方法探讨一项校本英语水平考试的内部因子结构。研究结果表明高阶因子模型与考试数据的拟合比较理想;多样本验证性因子分析的结果表明该模型在多次考试上的表现基本相同。本研究为该考试的构念效度提供了实证支撑,也为其他语言考试机构开展考试效度研究提供了参考。 | 范劲松 Ute Knoch 毕志伟 | 2016 | 外语测试与教学2016，，3： | 3 |
