Two soybean (Glycine max L. Merrill) cultivars, Shin-Tanbakuro and Midori, were grown under mild water stress conditions for 11 days at the vegetative growth stage in order to examine the effect of drought stress on plant biomass production, photosynthetic gas exchange, chlorophyll fluorescence and photoassimilate translocation along with changes in carbohydrates and nitrogen. Relative growth r...

5-aminolevulinic acid (ALA), a key precursor in the biosynthesis of porphyrins, can improve plant tolerance to various environmental stresses. However, it is unclear whether ALA poplar. Here, we investigated effects on poplars under drought and salt pretreatment exhibited less morphological damage, reduced leaf malonaldehyde content (MDA) electrolyte leakage (EL), increased relative water (RWC)...

Abstract The current research was carried out to evaluate the stress tolerance potential of durum wheat plants, in response inoculation native plant growth-promoting bacteria (PGPB), through assessing PSII photochemistry and photosynthetic traits, as well grain yield height, investigate possibility using PGPB a sustainable alternative or combination with traditional fertilization plans. A green...

INTRODUCTION Etravirine (ETR), a non-nucleoside reverse transcriptase inhibitor available in France since 2006, is indicated for the treatment of HIV-1 infection in combination with a ritonavir boosted protease inhibitor (PI) in antiretroviral treatment-experienced adult patients. To assess its impact in routine clinical care, our objective was to compare hospitalization rates in highly pre-tre...

Monogalactosyldiacylglycerol (MGDG) is the most abundant lipid on earth and constitutes about 50% of polar lipids in thylakoid membrane higher plants. MGDG synthase (MGD) key enzyme responsible for synthesis However, so far, function MGD gene plant stress responses still unknown, especially crop In this study, performances wild-type rice (Oryza sativa L. Nipponbare), OsMGD overexpression, RNA i...

Optical bistability is reported in InP/GaInAsP equilateral-triangle-resonator (ETR) microlasers, which are fabricated by planar technology. For a 30 mum side ETR microlaser with a 2-mum-wide output waveguide connected to one of the vertices of the ETR, hysteresis loops are observed for the output power versus the injection current from 215 to 235 K. The laser output spectra are measured in the ...

Solar induced chlorophyll fluorescence (SIF) emissions of photosynthetically active plants retrieved from space-borne observations have been used to improve models of global primary productivity. However, the relationship between SIF and photosynthesis in diurnal and seasonal cycles is still not fully understood, especially at large spatial scales, where direct measurements of photosynthesis ar...

Long-lived shade leaves of avocado had extremely low rates of photosynthesis. Gas exchange measurements of photosynthesis were of limited use, so we resorted to Chl fluorescence imaging (CFI) and spot measurements to evaluate photosynthetic electron transport rates (ETRs) and non-photochemical quenching (NPQ). Imaging revealed a remarkable transient heterogeneity of NPQ during photosynthetic in...

Cogongrass is one of the most destructive weed in China. It has been reported as one of the ten most troublesome weed species in the world. Therefore, developing an effective method to control this weed has become a significant and worthwhile practice. The effect of glyphosate on this weed growth was investigated during the 2009-2011 years. The photosynthesis, chlorophyll fluorescence, chloroph...
