The increasing resistance of bacteria and fungi to currently available antibiotics is a major concern world-wide,leading to enormous effort to develop novel antibiotics with new modes of *** recently reported that ABP-dHC-cecropin A exhibited strong antibacterial and antifungal activity,making it a candidate antibiotic *** this study,β-cyclodextrin(β-CD) combined with ABP-dHC-cecropin A enhanced the physical and chemical properties of ABP-dHC-cecropin A but did not significantly decrease its antibacterial ***,β-CD/ABP-dHC-cecropin A should be considered a novel antibacterial *** used β-CD/ABP-dHC-cecropin A as an anti-Agrobacterium compound to supplement transgenic poplar *** effects of the inclusion complex had little impact on plant ***,β-CD/ABP-dHC-cecropin A may be used as traditional antibiotics for poplar transplantation with greater antibacterial effects.

Subfamily 2 of SNF1-related protein kinase(SnRK2) plays important roles in plant abiotic stress responses as a global positive regulator of abscisic acid *** the genome of the model tree Populus trichocarpa,12 SnRK2 genes have been identified,and some are upregulated by abiotic *** this study,we heterologously overexpressed the PtSnRK2 genes in Arabidopsis thaliana and found that overexpression of PtSnRK2.5 and PtSnRK2.7 genes enhanced stress *** the PtSnRK2.5 and PtSnRK2.7 overexpressors,chlorophyll content,and root elongation were maintained under salt stress conditions,leading to higher survival rates under salt stress compared with those in the wild *** analysis revealed that PtSnRK2.7 overexpression affected stress-related metabolic genes,including lipid metabolism and flavonoid metabolism,even under normal growth ***,the stress response genes reported to be upregulated in Arabidopsis SRK2 C/SnRK2.6 and wheat SnRK2.8 overexpressors were not changed by PtSnRK2.7 ***,PtSnRK2.7 overexpression widely and largely influenced the transcriptome in response to salt stress;genes related to transport activity,including anion transport-related genes,were characteristically upregulated,and a variety of metabolic genes were specifically *** also found that the salt stress response genes were greatly upregulated in the PtSnRK2.7 *** together,poplar subclass 2 PtSnRK2 genes can modulate salt stress tolerance in Arabidopsis,through the activation of cellular signaling pathways in a different manner from that by herbal subclass 2 SnRK2 genes.
