Diversification of plant chemical phenotypes is typically associated with spatially and temporally variable plant-insect interactions. Floral scent is often assumed to be the target of pollinator-mediated selection, whereas foliar compounds are considered targets of antagonist-mediated selection. However, floral and vegetative phytochemicals can be biosynthetically linked and may thus evolve as integrated phenotypes. Utilizing a common garden of 28 populations of the perennial herb Arabis alpina (Brassicaceae), we investigated integration within and among floral scent compounds and foliar defense compounds (both volatile compounds and tissue-bound glucosinolates). Within floral scent volatiles, foliar volatile compounds, and glucosinolates, phytochemicals were often positively correlated, and correlations were stronger within these groups than between them. Thus, we found no evidence of integration between compound groups indicating that these are free to evolve independently. Relative to self-compatible populations, self-incompatible populations experienced stronger correlations between floral scent compounds, and a trend toward lower integration between floral scent and foliar volatiles. Our study serves as a rare test of integration of multiple, physiologically related plant traits that each are potential targets of insect-mediated selection. Our results suggest that independent evolutionary forces are likely to diversify different axes of plant chemistry without major constraints.

Angraecum sesquipedale, also known as Darwin's orchid, possesses an exceptionally long nectar spur. Charles Darwin predicted the orchid to be pollinated by a hawkmoth with a correspondingly long proboscis, later identified as Xanthopan praedicta. In this plant-pollinator interaction, the A.

Article Synopsis
  • A study was conducted on four common seedless grape varieties in China—Kyoho, Summer Black, Moldovan, and Sweet Sapphire—to compare their sensory properties and overall quality against commercially available Concord juice.
  • Kyoho and Sweet Sapphire had optimal Brix-acid ratios, while Kyoho also showed the highest aroma intensity with floral and fruity notes compared to Sweet Sapphire's grassy scent.
  • Concord juice emerged as the best option for color and aroma, with recommendations for blending Summer Black with Kyoho to enhance the overall quality of grape juice.

Ginger, as a globally vital medicinal and food homologous crop, plays an irreplaceable role in human diet and healthcare. However, during the storage of ginger, the decline of physical properties and degradation of volatile flavor quality have emerged as an industrial concern that severely restricts the market value of the product. MeJA plays an essential role in extending fruit shelf life and regulate the synthesis of volatiles in horticultural products, yet its application in ginger remains unreported.
