“…Likewise, insensitivity to bitterness of β-glucosides in bamboo lemurs would be a similarly adaptive trait for feeding on high-cyanide bamboo such as C. madagascariensis [14,16,17]. Some bamboo species, including Bambusa vulgaris consumed by P. simus, contain taxiphyllin, a different cyanogenic glucoside [12,[28][29][30]. However, the chemical structures of cyanogenic compounds in C. madagascariensis are still unknown.…”

Lowered sensitivity of bitter taste receptors to β-glucosides in bamboo lemurs: an instance of parallel and adaptive functional decline in TAS2R16?

Bitter taste facilitates the detection of potentially harmful substances and is perceived via bitter taste receptors (TAS2Rs) expressed on the tongue and oral cavity in vertebrates. In primates, TAS2R16 specifically recognizes β-glucosides, which are important in cyanogenic plants' use of cyanide as a feeding deterrent. In this study, we performed cell-based functional assays for investigating the sensitivity of TAS2R16 to β-glucosides in three species of bamboo lemurs ( Prolemur simus, Hapalemur aureus and H. griseus ), which primarily consume high-cyanide bamboo. TAS2R16 receptors from bamboo lemurs had lower sensitivity to β-glucosides, including cyanogenic glucosides, than that of the closely related ring-tailed lemur ( Lemur catta ). Ancestral reconstructions of TAS2R16 for the bamboo-lemur last common ancestor (LCA) and that of the Hapalemur LCA showed an intermediate sensitivity to β-glucosides between that of the ring-tailed lemurs and bamboo lemurs. Mutagenetic analyses revealed that P. simus and H. griseus had separate species - specific substitutions that led to reduced sensitivity. These results indicate that low sensitivity to β-glucosides at the cellular level—a potentially adaptive trait for feeding on cyanogenic bamboo—evolved independently after the Prolemur – Hapalemur split in each species.

Among the hydroxybenzaldehydes, only mono‐, di‐ and trihydroxybenzaldehydes are known. Salicylaldehyde (2‐hydroxybenzaldehyde) and 4‐hydroxybenzaldehyde represent more than 99% of the hydroxybenzaldehydes' market. The physical and chemical properties of hydroxybenzaldehydes are described. 2‐Hydroxy and 4‐hydroxybenzaldehydes react in a similar manner as phenol toward electrophiles. The aldehyde function can be reduced or oxidized to form a variety of compounds depending on the reagents and conditions used. Hydroxybenzaldehydes undergo the normal reactions of aromatic aldehydes. Most industrial methods for the manufacture of hydroxybenzaldehydes are based on phenol, but other routes exist, starting from hydroxybenzoic acids, by reduction, or from cresols, by oxidation. Both p ‐hydroxybenzaldehyde and salicylaldehyde have a low to moderate acute oral toxicity, but salicylaldehyde is, in addition, corrosive toward skin and appreciably irritating to the eyes. The hydroxybenzaldehydes are used primarily as chemical intermediates to a variety of products. The largest single use of salicylaldehyde is in the manufacture of coumarin. Both are used as intermediates in the synthesis of agrochemicals, pharmaceuticals, fragrances, and in electroplating. Condensation products of salicylaldehyde and diamines have important chelation properties, and have wide use in the stabilization of petroleum products, and in chemical processing, especially as oxidation catalysts. These and other applications to polymer chemistry are described.
