Water channel proteins, aquaporins, play fundamental roles in transmembrane water movements in plants. A new full-length cDNA encoding aquaporin was isolated from the seedlings of Jatropha curcas. The gene of the plasma membrane intrinsic protein (PIP) from J. curcas (JcPIP2) contained an 843 bp open reading frame encoding a protein of 280 amino acids. The amino acid sequence showed 94% identit...

Water deficit is a serious environmental factor limiting the growth and productivity of plants worldwide. Improvement of drought tolerance and efficient water use are significant strategies to overcome this dilemma. In this study, a drought-responsive transcription factor, nuclear factor Y subunit B 7 (PdNF-YB7), induced by osmotic stress (PEG6000) and abscisic acid, was isolated from fast-grow...

Enhancement of solubility is one of the difficult tasks which become challenges in formulation development of orally administered drug with poor aqueous solubility. Poor water solubility of drugs often causes significant problems in producing formulations of sufficiently high bioavailability, preventing effective use of the drugs. 'Mixed-solvency ' concept is the phenomenon to increase the solu...

The research was aimed to minimize product defects and lyophilization-induced denaturation of lasota vaccine. Sugars alone produced coherent cake but failed to protect virus during lyophilization. Maillard cake browning due to denaturation was evident in N,Z amine products. Polymers, PF-127 and PVP K-90 were able to produce porous cake structure and thus showed efficient water removal. DSC curv...

The micellization of F127 (E(98)P(67)E(98)) in dilute aqueous solutions of polyethylene glycol (PEG6000 and PEG35000) and poly(vinylpyrrolidone) (PVP K30 and PVP K90) is studied. The average hydrodynamic radius (r(h,app)) obtained from the dynamic light scattering technique increased with increase in PEG concentration but decreased on addition of PVP, results which are consistent with interacti...

Previously, we obtained the sweetpotato somatic hybrid KT1 from a cross between sweetpotato (Ipomoea batatas (L.) Lam.) cv. Kokei No. 14 and its drought-tolerant wild relative I. triloba L. KT1 not only inherited the thick storage root characteristic of Kokei No. 14 but also the drought-tolerance trait of I. triloba L. The aim of this study was to explore the molecular mechanism of the drought ...

In previous studies, we demonstrated that ammonium nutrition enhances the drought tolerance of rice seedlings compared to nitrate nutrition and contributes to a higher root water uptake ability. It remains unclear why rice seedlings maintain a higher water uptake ability when supplied with ammonium under drought stress. Here, we focused on the effects of nitrogen form and drought stress on root...

Drought is a severe abiotic stress that imposes serious threat to rice productivity. Although previous studies have found melatonin can promote seed germination, the physiological regulation mechanism of drought tolerance in germination mediated by exogenous still unclear. In order overcome these challenges, polyethylene glycol 6000 (PEG6000) at concentrations 20% and 35% was used simulate osmo...

Background: Solid dispersions (SDs) are the dispersion of hydrophobic drugs in an inert hydrophilic carrier. SDs prepared to improve dissolution properties and bioavailability slightly water-soluble drug molecules by dispersing them into carrier.
 Aims Objective: Evaluate solubility Dispersion Lercanidipine Hydrochloride (LER).
 Materials Methods: To study effect polymer, studies were...

The argonaute (AGO) protein, as an important member of the small RNA (sRNA) regulatory pathway gene-silencing complex (RNA-induced silencing complex, RISC), is a key protein that mediates gene and plays role in recruitment sRNAs. In this study, bioinformatics was used to identify AGO family poplar study its expression various tissues response abiotic stress treatments. A total 15 PtAGO genes we...
