KT/HAK/KUP potassium transporter genes differentially expressed during fruit development, ripening, and postharvest shelf-life of ‘Xiahui6’ peaches

Biochemical composition and antioxidant activity affected by spraying potassium sulfate in black grape (Vitis vinifera L. cv. Rasha)

“…For instance, application of suitable potassium nutrition helps to increase both coloring and polyphenolic content of berries . Potassium is also important for proper development of other fruits, such as the apple, melon, peach, and strawberry . The total phenolics in blackberries were decreased as potassium level was decreased…”

Differential expression of iron–sulfur cluster biosynthesis genes during peach fruit development and ripening, and their response to iron compound spraying

“…1D). When peach fruit reached their final volume and suffered postharvest ripening, less Fe but more cation elements, such as potassium (Song et al, 2015), were required to maintain normal Fe-dependent metabolism or processes.…”

“…The Ubiquitin (Genebank No. KJ598788) and Actin (KP690196) genes in peach were used as reference genes, according to the studies of Tong et al (2009) and Song et al (2015). Specific primers of Fe-S cluster biosynthesis genes and the control gene were listed in Supplemental Table 1.…”

“…1A). Based on the detailed description of peach development (Lombardo et al, 2011;Song et al, 2015), 'Xiahui8 peach fruit development was divided into four distinct stages. Prior to these four stages, is the early (E) fruit development stage, in which immature fruitlets are originally formed.…”

Molecular Cloning and Functional Analysis of a Na+-Insensitive K+ Transporter of Capsicum chinense Jacq

“…At the transcriptional level, the members of this family are expressed in different tissues and organs (Su et al, 2002; Ahn et al, 2004; Yang et al, 2014; Song Z. et al, 2015) and are regulated by physiological conditions and environmental factors in a differential manner according to the group to which they belong (Véry et al, 2014; Song Z. et al, 2015). In particular, the genes that encode the HAK transporters of group I are positively regulated in roots under K + starvation (Santa-María et al, 1997; Bañuelos et al, 2002; Ahn et al, 2004; Martínez-Cordero et al, 2004; Nieves-Cordones et al, 2007; Alemán et al, 2009; Horie et al, 2011; Shen et al, 2015), suggesting an adaptive role of group I transporters under conditions of low K + availability.…”
