Uniconazole, a plant growth retardant, possessesthe ability to improve quality and increase tolerance of plant. However, it is known little about the effects of uniconazoleon root. In this study, uniconazole treatments that were appliedthrough seed soaking, promoted soybean root development,and the microstructure of root showed increase of corticalthickness and cortex cell width. Meanwhile, the endogenoushormone content also altered in root after uniconazoletreatments. To obtain the molecular mechanism underlyingthe effects of uniconazole on root, we performed an RNAseqof roots harvested 3 days after uniconazole treatment. Through analyses of phytohormone-associated genes forendogenous hormones changes, we found that not only GAbiosynthesis pathway but also the regulation genes of thepathway were affected. Above all, the dominant pathwayplant hormone signal transduction may be the main factor ofthe cambium proliferation, in especial ethylene/ERF signalingpathway. Moreover, the transcriptome demonstrated differentiallyexpressed genes that determined cell division and cell wallmodification may be regulators of root growth. CLE signalingand receptor-like kinases may play a crucial role in the rootelongation. Besides, 177 transcription factors (TFs) wereinvolved in response to uniconazole. Taken together, allthese findings provide insights into the complex molecularmechanisms associated with root development after uniconazoletreatment.

Polymeric surfactant can simultaneously thicken aquous phase and reduce water–oil interfacial tension(IFT), which makes it present a great application prospect in the oilfield taword enhanced oil recovery(EOR). There are two kinds of polymeric surfactant with different molecular structures are commonlyused to realize the salt resistance, thermal endurance and shear resistance. However, the influence ofthe molecular structure of polymeric surfactant on their properties related on EOR are not well understood. In the work, we synthesized two kinds of polymeric surfactants with different molecular structurewhich respectively named intermolecular association molecule (IAM) and rigid chain molecule (RCM). Their physico-chemical properties, porous media transportation and EOR are compared with a series ofexperiments. It is found that the hydrodynamic characteristic sizes and retention of IAM are higher thanthose of RCM via the membrane filtration test and nuclear magnetic resonance (NMR) scan. These featuresmake IAM have a larger resistance factor and residual resistance factor than RCM and hydrolyzedpolyacrylamide (HPAM) in the same viscosity. Compare to HPAM with shear thinning, RCM presents aNewtonian fluid region and IAM presents a shear thickening region when the shear rate is lower than1 s 1. The spatial structure of IAM can pack oil drop into its network, which make it easy to form oilin-water-in-oil (O/W/O) emulsions. Moreover, the concentration and water–oil ratio (WOR) rarely affectthe stability of IAM emulsions once the intermolecular association generated. The increamental oil recoveryfactor of IAM is 17.5% after water flooding in the three-layer core flooding experiments with the permeabilityof 500 mD, 1500 mD and 3000 mD at 55℃, which is higher than that of 14.5% for RCM and11.4% for HPAM.
