Abstract Lettuce (Lactuca sativa ‘Salinas’) seeds fail to germinate when imbibed at temperatures above 25°C 30°C (termed thermoinhibition). However, of an accession Lactuca serriola (UC96US23) do not exhibit thermoinhibition up 37°C in the light. Comparative genetics, physiology, and gene expression were analyzed these genotypes determine mechanisms governing regulation seed germination by temperature. Germination two was differentially sensitive abscisic acid (ABA) gibberellin (GA) elevated...
We report an improved assembly (v3.6.1) of the melon (Cucumis melo L.) genome and a new annotation (v4.0). The optical mapping approach allowed correcting order orientation 21 previous scaffolds permitted to correctly define gap-size extension along 12 pseudomolecules. A comprehensive was also built in update v3.5.1, released more than six years ago. Using integrative pipeline, based on exhaustive RNA-Seq collections ad-hoc transposable element annotation, we identified 29,980 protein-coding...
Fruit ripening is divided into climacteric and non-climacteric types depending on the presence or absence of a transient rise in respiration rate production autocatalytic ethylene. Melon ideal for study fruit ripening, as both varieties exist. Two introgressions accession PI 161375, encompassed QTLs ETHQB3.5 ETHQV6.3, 'Piel de Sapo' background are able to induce independently. We report that gene underlying ETHQV6.3 MELO3C016540 (CmNAC-NOR), encoding NAC (NAM, ATAF1,2, CUC2) transcription...
The genome of the melon (Cucumis melo L.) double-haploid line DHL92 was recently sequenced, with 87.5 and 80.8% scaffold assembly anchored oriented to 12 linkage groups, respectively. However, insufficient marker coverage a lack recombination left several large, gene rich scaffolds unanchored, some unoriented. To improve anchoring orientation assembly, we used resequencing data between parental lines develop new set SNP markers from unanchored scaffolds.A high-resolution genetic map composed...
Thermoinhibition, or failure of seeds to germinate when imbibed at warm temperatures, can be a significant problem in lettuce (Lactuca sativa L.) production. The reliability stand establishment would improved by increasing the ability high temperatures. Genes encoding germination- dormancy-related proteins were mapped recombinant inbred line population derived from cross between L. cv. Salinas and serriola accession UC96US23. This revealed several candidate genes that are located genomic...
Sugar content is the major determinant of both fruit quality and consumer acceptance in melon (Cucumis melo L), a primary target for crop improvement. Near-isogenic lines (NILs) derived from intraspecific cross between 'Piel de Sapo' (PS) type exotic cultivar 'Songwhan Charmi' (SC), several populations generated PS x Ames 24294 ("Trigonus"), wild melon, were used to identify QTL related sugar organic acid composition. Seventy-eight detected across locations different years, with three...
Abstract Melon is as an alternative model to understand fruit ripening due the coexistence of climacteric and non-climacteric varieties within same species, allowing study processes that regulate this complex trait with genetic approaches. We phenotyped a population recombinant inbred lines (RILs), obtained by crossing (Védrantais, cantalupensis type) non-climcteric variety (Piel de Sapo T111, inodorus type), for traits related maturation ethylene production. Individuals in RIL exhibited...
Fusarium head blight (FHB) caused by graminearum Schwabe causes losses in wheat ( Triticum aestivum L.) seed quality and yield. Field studies were conducted 2000 2001 to investigate F. infection (SI) its relationship germination vigor the production of mycotoxin deoxynivalenol (DON). Seeds from four soft red winter cultivars having different levels Type II resistance harvested at frequent intervals during development maturity. Low SI occurred late 2000, which resulted high quality. In 2001,...
Abstract Introgression lines are valuable germplasm for scientists and breeders, since they ease genetic studies such as QTL interactions positional cloning well the introduction of favorable alleles into elite varieties. We developed a novel introgression line collection in melon using two commercial European varieties with different ripening behavior, climacteric cantalupensis ‘Védrantais’ recurrent parent non-climacteric inodorus ‘Piel de Sapo’ donor parent. The contains 34 lines,...
Melon is an economically important crop with widely diverse fruit morphology and ripening characteristics. Its diploid sequenced genome multiple genomic tools make this species suitable to study the genetic architecture of traits. With development introgression line population elite varieties 'Piel de Sapo' 'Védrantais', we present a powerful tool traits that can also facilitate characterization or pyramidation QTLs in inodorous melon types. The consists 36 lines covering almost 98% genome,...
Fusarium head blight (FHB) caused by graminearum Schwabe can cause extensive losses in wheat ( Triticum aestivum L.) seed quality and yield. Greenhouse studies were conducted 2000 2001 to investigate the movement of F. into floral components spike following point inoculation (PI) a middle floret. The visual greenhouse rating spikelet infection (severity) PI for all genotypes Uniform Northern Southern FHB Screening Nurseries with various levels Type II resistance was also related same spikes...

Abstract Background Cannabis sativa is a primarily dioecious angiosperm that exhibits sexual developmental plasticity. Developmental genes for staminate male flowers have yet to be elucidated; however, there are regions of male-associated DNA from (MADC) correlate with the formation pollen producing flowers. MADC2 an example PCR-based genetic marker has been shown produce 390-bp amplicon correlates expression phenotypes. We demonstrate applications cost-effective high-throughput genotyping...
Abstract Fleshy fruit evolved independently multiple times during angiosperm history. Many climacteric fruits utilize the hormone ethylene to regulate ripening. The fruitENCODE project shows there are evolutionary origins of regulatory circuits that govern Eudicot with recent whole-genome duplications (WGDs) their ripening systems using duplicated floral identity genes, while others without WGD utilised carpel senescence genes. monocot banana uses both leaf and floral-identity forming two...
Fleshy fruit evolved independently multiple times during flowering plant (angiosperm) history yet many utilize the hormone ethylene to regulate ripening. The fruitENCODE project highlights three evolutionary origins of ripening regulatory circuits. Eudicots that experienced recent whole-genome duplications (WGDs) their systems using duplicated floral identity genes, while others without WGD utilised carpel senescence genes. monocot banana uses both floral-identity and leaf forming two...
Abstract Cultivation of Cannabis sativa is increasing because its therapeutic value and recognition as a multi-purpose sustainable crop. Targeting Induced Local Lesions in Genomes (TILLING) versatile reverse genetics approach that unlocks induced variation through mutagenesis to accelerate the development new cultivars contribute functional validation genes. Increasingly efficient next-generation sequencing technologies genomic resources have combined make TILLING by (TbyS) an attractive...
