Genome-wide analysis and identification of KT/HAK/KUP potassium transporter gene family in peach (Prunus persica)

Z. Z. Song, Ma, R. J., and Yu, M. L., Genome-wide analysis and identification of KT/HAK/KUP potassium transporter gene family in peach (Prunus persica), vol. 14, pp. 774-787, 2015.

The KT/HAK/KUP family members encoding high-affinity potassium (K+) transporters mediate K+ transport across the plasma membranes of plant cells to maintain plant normal growth and metabolic activities. In this paper, we identified 16 potassium transporter genes in the peach (Prunus persica) using the Hidden Markov model scanning strategy and searching the peach genome database. Utilizing the Arabidopsis KT/HAK/KUP family as a reference, phylogenetic analysis indicates that the KT/HAK/KUP family in the peach can be classified into 3 groups.

Identification of differentially expressed genes associated with flower color in peach using genome-wide transcriptional analysis

Y. Zhou, Wu, X. X., Zhang, Z., and Gao, Z. H., Identification of differentially expressed genes associated with flower color in peach using genome-wide transcriptional analysis, vol. 14, pp. 4724-4739, 2015.

Flower color is an important trait of the ornamental peach (Prunus persica L.). However, the mechanism responsible for the different colors that appear in the same genotype remains unclear. In this study, red samples showed higher anthocyanins content (0.122 ± 0.009 mg/g), which was significantly different from that in white samples (0.066 ± 0.010 mg/g). Similarly to carotenoids content, red extract (0.058 ± 0.004 mg/L) was significantly higher in white extract (0.015 ± 0.004 mg/L).
