- Abstract:
- ... The hormone gibberellic acid (GA) regulates growth and development throughout the plant life cycle. DELLA proteins are key components of the GA signalling pathway and act to repress GA responses. The “DELLA” amino acid motif is highly conserved among diverse species and is essential for GA-induced destruction of DELLA proteins, which relieves repression. Six genes encoding the DELLA motif were ide ...

- Abstract:
- ... An integrated consensus genetic map for apple was constructed on the basis of segregation data from four genetically connected crosses (C1 = Discovery × TN10-8, C2 = Fiesta × Discovery, C3 = Discovery × Prima, C4 = Durello di Forli × Fiesta) with a total of 676 individuals using CarthaGene® software. First, integrated female–male maps were built for each population using common female–male simple ...

- Abstract:
- ... Simple sequence repeat (SSR) markers developed from Malus, as well as Prunus, Pyrus and Sorbus, and some other sequence-tagged site (STS) loci were analysed in an interspecific F₁ apple progeny from the cross ‘Fiesta’ × ‘Totem’ that segregated for several agronomic characters. A linkage map was constructed using 259 STS loci (247 SSRs, four SCARs and eight known-function genes) and five genes for ...

- Abstract:
- ... Woolly apple aphid (WAA; Eriosoma lanigerum Hausm.) can be a major economic problem to apple growers in most parts of the world, and resistance breeding provides a sustainable means to control this pest. We report molecular markers for three genes conferring WAA resistance and placing them on two linkage groups (LG) on the genetic map of apple. The Er1 and Er2 genes derived from 'Northern Spy' and ...

- Abstract:
- ... Microribonucleic acids (miRNAs) are small, non-coding RNAs that play important regulatory roles by down-regulating target transcripts in a sequence-specific manner. The miRBase Registry (Release 8.2) lists 732 miRNAs from flowering plant species, with the majority identified from Arabidopsis, rice and poplar where genome sequence is available. In the absence of genomic sequence and on the basis th ...

- Abstract:
- ... Breeding for fruit quality traits is complex due to the polygenic (quantitative) nature of the genetic control of these traits. Therefore, to improve the speed and efficiency of genotype selection, attention in recent years has focused on the identification of quantitative trait loci (QTLs) and molecular markers associated with these QTLs. However, despite the huge potential of molecular markers i ...

- Abstract:
- ... Fruit ripening can be considered as a complex set of biochemical and physiological changes occurring at the end of the developmental stage. Ripe fruit texture notably affects overall quality and consumer appreciation. Excessive softening limits shelf-life and storability, thereby increasing disease susceptibility and economic loss. Fruit softening is a process due to the depolymerisation of differ ...

- Abstract:
- ... The rosy apple aphid (Dysaphis plantaginea), the leaf-curling aphid (Dysaphis cf. devecta) and the green apple aphid (Aphis pomi) are widespread pest insects that reduce growth of leaves, fruits and shoots in apple (Malus × domestica). Aphid control in apple orchards is generally achieved by insecticides, but alternative management options like growing resistant cultivars are needed for a more sus ...

Marker-assisted selection (MAS) offers quick and reliable prediction of the phenotypes of seedlings in large populations and thus opens new approaches for selection to breeders of apple (Malus x domestica Borkh.). The development of framework maps enables the discovery of genetic markers linked to desired traits. Although genetic maps have been reported for apple scion cultivars, none has previous ...

Gala after genetic transformation, its identification represents only the first step in understanding the molecular mechanisms and, hence, the network ...
