The carboxylic acids produced by the reductive tricarboxylic acid (rTCA) cycle are possibly a biosynthetic core of initial life, although several steps such as the reductive kinetics of oxaloacetate (OAA) to malate (MA) are problematic by conventional chemical routes. In this context, we studied the kinetics of this reaction as promoted by ZnS mineral photoelectrochemistry. The quantum efficien...

Coffee is one of the main agricultural commodities in world. Thus, research aimed at reducing productive risks crop has been increasingly encouraged, among which use plant hormones stands out. In addition, objective this work was to analyze effect application indole-3-acetic acid on growth, nutrition and gas exchange young Coffea arabica L plants. The experiment carried out field city Alegre, E...

Abstract Coagulation factor IX (FIX) is a complex post-translationally modified human serum glycoprotein and high-value biopharmaceutical. The quality of recombinant FIX (rFIX), especially complete γ-carboxylation, critical for rFIX clinical efficacy. Bioreactor operating conditions can impact production post-translational modifications (PTMs). With the goal optimizing production, we developed ...

Plants growing in high-light environments during winter often exhibit leaf reddening due to synthesis of anthocyanin pigments, which are thought to alleviate photooxidative stress associated with low-temperature photoinhibition through light attenuation and/or antioxidant activity. Seasonal high-light stress can be further exacerbated by a limited photosynthetic capacity, such as nitrogen-defic...

Traditional Chinese medicine relies heavily on herbs, yet there is no information on how these herb plants would respond to climate change. In order to gain insight into such response, we studied the effect of elevated [CO2] on Isatis indigotica Fort, one of the most popular Chinese herb plants. The changes in leaf photosynthesis, chlorophyll fluorescence, leaf ultrastructure and biomass yield ...

We review the photosynthetic responses to drought in field-grown grapevines and other species. As in other plant species, the relationship between photosynthesis and leaf water potential and/or relative water content in field-grown grapevines depends on conditions during plant growth and measurements. However, when light-saturated stomatal conductance was used as the reference parameter to refl...

The intensive use of land to produce vegetables results in high soil degradation and cultivated area. techniques resources that make production possible under unfavorable conditions can be decisive for agriculture. Thus, this study aimed evaluate the isolated joint effects liming thiamine application on development bell pepper plants. treatments consisted three different base saturation (36, 60...

In recent years, a great deal of attention has been paid by the scientific community to improving efficiency photosynthetic carbon assimilation, plant growth and biomass production in order achieve higher crop productivity. Therefore, primary carboxylase enzyme process Rubisco received considerable focused on many aspects function including protein structure, engineering assembly, activation ki...

BACKGROUND AND AIMS Photosynthetic plasticity in response to a range of environmental factors that include [CO(2)], water availability, light intensity and temperature, is ubiquitous among plants with crassulacean acid metabolism (CAM). The present study examined how seasonal changes in light availability, as experienced by greenhouse CAM crops in northern latitude regions, influence diel carbo...
