Photodegradation of Malachite Green by Nanostructured Bi2WO6 Visible Light-Induced Photocatalyst

open access: yesInternational Journal of Photoenergy, 2012
Bi2WO6 photocatalyst was first utilized to degrade malachite green. The effects of the concentration of malachite green, the pH value, and the concentration of Bi2WO6 on the photocatalytic efficiency were investigated.

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Biochemical phosphorus allocation is linked to photosynthetic phosphorus‐use efficiency in a phosphorus‐impoverished environment

open access: yesNew Phytologist, EarlyView.
Summary Highly efficient phosphorus (P)‐use strategies have evolved in plants, allowing them to thrive in severely P‐impoverished environments. However, it remains unclear how allocating leaf P to biochemical fractions, including specific P‐containing metabolites, contributes to instantaneous photosynthetic P‐use efficiency (iPPUE) and the position of ...

Lipid vesicles chaperone an encapsulated RNA aptamer. [PDF]

open access: yes, 2018
The organization of molecules into cells is believed to have been critical for the emergence of living systems. Early protocells likely consisted of RNA functioning inside vesicles made of simple lipids.

Molecular Targeted Suppression of Male Fertility in Amaranthus palmeri S. Watson: Function and Layered Double Hydroxide Nanosheets‐Based Delivery System of ApmiR319

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Amaranthus palmeri is one of the most troublesome invasive agricultural weeds worldwide, exhibiting super invasiveness and high resistance to conventional management strategies. Artificial microRNA‐mediated silencing technology, coupled with a nanoparticle‐mediated delivery system, represents an attractive approach for fertility control in A ...

Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]

open access: yes, 1985
Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

Divergent Phosphorus‐Mining Strategies in Simple and Compound Cluster Roots in Extremely Phosphorus‐Impoverished Soils in Southwest Australia

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Most Proteaceae and some Fabaceae species produce specialised cluster roots (CRs), and are abundant in severely phosphorus (P)‐impoverished soils in southwest Australia. Two types of CRs, compound and simple, have been identified. However, the difference in their P‐mining strategies remains unclear. Therefore, we conducted glasshouse and field

Study on malachite green residue detection system

open access: yesMATEC Web of Conferences, 2018
In this work, a malachite green residue detection system for aquaculture monitoring was established. The system includes a new method based on DNA adapter body of malachite green sensor, a handheld electrochemical detector, and the combination of the two,
