Ammonium is one of the prevalent nitrogen sources for growth and development higher plants. acquisition from soil facilitated by ammonium transporters (AMTs), which are plasma membrane proteins that exclusively transport ammonium/ammonia. However, functional characteristics molecular mechanisms AMTs in apple remain unclear. In this work, 15 putative AMT genes were identified classified into fou...

The paper presents the chemical composition of fruits three apple cultivars (Jonagold Decosta, Red Idared and Gala Schnitzer Schniga) fertilized with treatment: T$_{1}$ (control-without fertilization); T$_{2}$ (300 kg/ha NPK (6:18:36) + 150 N (calcium ammonium nitrate-CAN)) T3 (foliar nutrition-mixture organic-mineral fertilizer commercially named 'FitoFert Kristal' (0.6%) (10:40:10) (20:20:20)...

Multiple quantitative trait loci (QTLs) associated with fruit size have been reported in apple (Malus domestica Borkh.); however, few fully characterized and/or validated. A pedigree-based QTL analysis approach was used to examine the genetic basis of weight ‘Honeycrisp’-derived germplasm. Fourteen breeding parents were represented by 814 offspring from 13 full-sib families ‘Honeycrisp’ and ‘Mi...
