“…In this study, a series of putative cis-elements were found that are involved in the abiotic stress response, Ca 2+ -response, light and circadian rhythm regulations, and seed development. Such findings are similar to previously reported KT/HAK/KUP members in maize (Zhang et al, 2012). Among these putative cis-elements, the water-stress responsive element ACGTATERD1 was distributed in all the 16 KT/HAK/KUP family genes, implying that KT/HAK/KUP family genes in the peach are prone to regulation by drought.…”

“…The availability of the complete genome sequences and the previous identification of KT/HAK/KUP family genes from some plant species (Rubio et al, 2000;Baňuelos et al, 2002;Gupta et al, 2008;Song et al, 2011;Zhang et al, 2012) enables the comparison of individual groups, which was based on the classification in Arabidopsis as a criterion. Overall, there were 16 KT/HAK/KUP family genes in the peach, more than in Arabidopsis (13) and less than in the grapevine (18), maize (27), and rice (27) (Gupta et al, 2008;Song et al, 2011;Zhang et al, 2012), which may reflect the fact that the peach has a larger genome of 220-230 Mbp (Jung et al, 2008) greater than that of Arabidopsis (i.e., 145 Mbp) (Huala et al, 2001) but shorter than that of the grapevine (i.e., 475 Mbp) (Velasco et al, 2007), rice (i.e., 430 Mbp) (Goff et al, 2002), and maize (i.e., 2.3 Gbp) (Schnable et al, 2009).…”

ABSTRACT. The KT/HAK/KUP family members encoding highaffinity 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. Genomic localization indicated that 16 KT/ HAK/KUP family genes were well distributed on 7 scaffolds. Gene structure analysis showed that the KT/HAK/KUP family genes have 6-9 introns. In addition, all of the KT/HAK/KUP family members were hydrophobic proteins; they exhibited similar secondary structure patterns and homologous tertiary structures. Putative cis-elements involved in abiotic stress adaption, Ca 2+ response, light and circadian rhythm regulation, and seed development were observed in the promoters of the KT/HAK/KUP family genes. Subcellular localization prediction indicated that the KT/HAK/KUP members were mainly 775 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (1): 774-787 (2015) Analysis of KT/HAK/KUP family gene in peach located in the plasma membrane. Expression levels of the KT/HAK/ KUP family genes were much higher in the fruit and flower than those in the other 7 tissues examined, indicating that the KT/HAK/KUP family genes may have important roles in K + uptake and transport, which mainly contribute to flower formation and fruit development in the peach.

Plant growth regulators (PGRs) are commonly used in cereal cropping systems to restrict plant height and control lodging. Ethephon has been reported to shorten internodes and increase grain yield of maize. To analyze the transcriptomic profiles of maize internode elongation following ethephon treatment, differentially expressed genes were compared between the treatment and control samples of inbred line Zong 31 using the Affymetrix Maize Genome Array. According to the microarray data, 326 probe sets showed significant change in expression. Further research revealed that the most remarkable effects of ethephon on maize internodes elongation occurred during a 48 h period, when 89 differentially expressed genes were detected. There were dramatic change in transcript levels at 24 h and six Auxin transport genes and four gibberellin biosynthesis pathway genes were differentially expressed in Zong 31 in response to ethephon treatment. In summary, we showed that gaseous ethylene release is involved in internode meristem cell elongation through the regulation of plant hormone signaling in maize. This work provides a platform for studies in which candidate genes will be functionally tested for involvement in internode elongation.

“…Plant KUP/HAK/KT genes encode a large family of high-affinity K + transporters (Amrutha et al 2007;Gupta et al 2008;He et al 2012;Hyun et al 2014;Yang et al 2009;Zhang et al 2012).

This suggested that plant KT/ HAK/KUP transporters might not only conduct primary K + uptake from soil but also contribute to the cellular K + homeostasis (Coskun et al 2013;Jiang et al 2013).…”

Aims KUP/HAK/KT transporters mainly play a role of K + uptake in plants. PaHAK1 was a previously isolated KUP/HAK/KT transporter gene from a high K + plant Phytolacca acinosa Roxb. In this study, we want to identify the function of PaHAK1. Methods PaHAK1 was overexpressed in eukaryotes including Arabidopsis, rice, and yeast. The growth and K + uptake of transgenic lines in media of low K + concentration were investigated. Results We found that PaHAK1 rescued the growth phenotype of athak5 seedlings which was hard to grow in the media of 10 μM K + . Faster depletion from diluted K solutions was detected for transgenic than for WT plants. Moreover, PaHAK1 confers the growth of K + uptake deletion yeast mutant on AP media containing 50 μM of K + . Conclusions Taken together, these results suggest an important role for PaHAK1 transporter on K + uptake.
