Abstract Phenolic compounds in apples 17 cultivars ( Malus domestica Borkh.) and 3 wild forms sp.) were analyzed to study the impact of genetic background, growth site, fruit bagging. The altitude was studied nine by analyzing fruits collected from orchards at three altitudes. Procyanidin B2 (71–628 μg/g fresh weight), −)-epicatechin (35–357 μg/g), chlorogenic acid (28–563 μg/g) always most abu...

Apple (Malus × domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive triterpenes and phenolic compounds with potentially valuable pharmacological functions. This thesis investigated the effects of pre-harvest and postharvest factors on concentrations of these bioactive compounds in apples. It also studied the effect of ozone treatment, before or during storage,...

The bHLH (basic helix-loop-helix) transcription factor family is the second largest in plants. It occurs in all three eukaryotic kingdoms, and plays important roles in regulating growth and development. However, family members have not previously been studied in apple. Here, we identified 188 MdbHLH proteins in apple "Golden Delicious" (Malus × domestica Borkh.), which could be classified into ...

Background Knowledge about single nucleotide polymorphism (SNP) markers is extremely important in the development of genotyping assays, allowing improvements in plant breeding through marker-assisted selection. With the emergence of next generation sequencing platforms, high-density SNP discovery in the genome of plant crops becomes more achievable. In this project, we carried out whole genome ...

Apple seeds (Malus domestica Borkh. cv Golden Delicious) were stratified at 5 and 15 degrees C for various lengths, weighed, and soluble protein of axis and cotyledon tissue was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Only seeds treated at 5 degrees C germinated; seeds treated at 15 degrees C did not germinate. Optimal germination required 63 days of stratificatio...

Galactomannans (GMs) extracted from seeds of a native Brazilian specie designated Cassia fastuosa (cassia) and from Cyamopsis tetragonolobus (guar gum – a commercial GM) were mixed with agar, in the proportion of 3/3 g.L (w/w), and used as a gelling agent in Marubakaido apple rootstock (Malus prunifolia Borkh) micropropagation. The rheological measurements of the gels showed a good interaction ...
