Soluble sugars play important roles in plant development and stress response, and the nitrogen supply level can affect the among-organ distribution and metabolism of sugar in plants and, in turn, plant growth. To explore the adaptive response of apple root growth to nitrogen supply and its
Alternate bearing (AB) trees, including Malus prunifolia, are characterized by alternating cycles of heavy (ON tree) and low (OFF tree) fruit loads. The mechanisms regulating the AB phenomenon have not been fully characterized. We completed an iTRAQ-based investigation of M. prunifolia to identify
Sucrose non-fermenting-1-related protein kinase-1 (SnRK1) plays an important role in metabolic regulation in plant. To understand the molecular mechanism of amino acids and carbohydrate metabolism in Malus hupehensis Rehd. var. pinyiensis Jiang (Pingyi Tiancha, PYTC), a full-length cDNA clone
Apple trees (Malus domestica L.) are often exposed to severe water stress in the summertime. We determined how levels of nonstructural carbohydrates (NC) changed in the leaves of two cultivars - drought-tolerant 'QinGuan' and drought-sensitive 'NaganoFuji' - when plants were subjected for 10 d to a
To unravel the physiological and molecular regulation mechanisms underlying the variation in copper (Cu)accumulation, translocation and tolerance among five apple rootstocks, seedlings were exposed to either basal or excess Cu. Excess Cu suppressed plant biomass and root architecture, which was less
