REVIEW
Olivier Gnankiné, Imaël Henri Nestor Bassolé
Widespread resistance of Anopheles sp. populations to pyrethroid insecticides has led to the search for sustainable alternatives in the plant kingdom. Among many botanicals, there is great interest in essential oils and their constituents. Many researchers have explored essential oils (EOs) to determine their toxicity and identify repellent molecules that are effective against Anopheles populations. Essential oils are volatile and fragrant substances with an oily consistency typically produced by plants. They contain a variety of volatile molecules such as terpenes and terpenoids, phenol-derived aromatic components and aliphatic components at quite different concentrations with a significant insecticide potential, essentially as ovicidal, larvicidal, adulticidal, repellency, antifeedant, growth and reproduction inhibitors...

I here present a survey of generic names with standing in the prokaryotic nomenclature that have homonyms with standing under the International Code of Zoological Nomenclature and/or the International Code of Nomenclature for algae, fungi, and plants. I especially discuss such names added after Principle 2 of the Bacteriological Code/Prokaryotic Code was changed in 1999 to make the prokaryote nomenclature not independent of botanical and zoological nomenclature. Cases include the genera Micromonas, Quadrococcus, Yania, Sinococcus, and Meganema...

The issues including excessive pesticide residues and heavy metal contamination have become the bottle-neck in the development of Chinese herbal medicines. Compared with traditional chemical pesticides, biological pesticides, especially botanical pesticides, are more safe and environment-friendly, which were beneficial to the quality improvement Chinese medicinal materials. Though there exists a weak basic research and it is hard for promotion and regulation, the policy of good and the desire for botanical pesticides will accelerate its development, and replace traditional chemical pesticides gradually...

The discovery of potent cytotoxic isolates from botanicals provides an opportunity to explore this viable tool for cancer chemoprevention. The antileukemic potential of clerodane diterpene from Polyalthia longifolia leaves has already been established. However, in this present study, utilizing chromatographic techniques we report for the first time, the isolation of a rare tetranorditerpene (compound 1) from P. longifolia. The structure of compound 1 was elucidated and confirmed by spectrophotometric data. UPLC-MS analysis was conducted on the methanolic extract, ethyl acetate fraction, and isolated tetranorditerpene showed that the tetranorditerpene is one of the major constituents of the plant with a retention time of 30...

Plants are ubiquitous and found in virtually every ecosystem on Earth, but their biology is often poorly understood, and inaccurate ideas about how plants grow and function abound. Many articles have been published documenting student misconceptions about photosynthesis and respiration, but there are substantially fewer on such topics as plant cell structure and growth; plant genetics, evolution, and classification; plant physiology (beyond energy relations); and plant ecology. The available studies of misconceptions held on those topics show that many are formed at a very young age and persist throughout all educational levels...

Ficus elastica, otherwise known as India Rubber (although its geographical origins are unclear), was an important source of latex in the early 19(th) century and was widely cultivated in tropical Asia. Like all figs, F. elastica is dependent on tiny, highly specific wasps for pollination, and detailed studies based out of Singapore in the 1930s suggested that through the loss of its pollinator F. elastica was extinct in the wild. However, around 2005 wild seedlings of F. elastica began appearing in Singapore...

Climate change has resulted in major changes in plant phenology across the globe that includes leaf-out date and flowering time. The ability of species to respond to climate change, in part, depends on their response to climate as a phenological cue in general. Species that are not phenologically responsive may suffer in the face of continued climate change. Comparative studies of phenology have found phylogeny to be a reliable predictor of mean leaf-out date and flowering time at both the local and global scales...

Although there have been augmented advances in drug discovery, current OA management is inadequate due to the lack of successful therapies proven to be effective in modifying disease progression. For some, the risk outweighs the benefit. As a result, there is a desperate need for safe and efficacious natural alternatives. Here we evaluated a composition from Morus alba, Scutellaria baicalensis, and Acacia catechu in maintaining joint structural integrity and alleviating OA associated symptoms in monoiodoacetate- (MIA-) induced rat OA disease model...
