Chemical Variability of Hexane Extracts from Five Subspecies of Calendula suffruticosa from Spain
Abstract The chemical profile of the hexane extracts of the subspecies carbonellii, greuteri, marginata, trialata, and vejerensis of Calendula suffruticosa growing in Spain, herein described for the first time, were studied to access their value as a chemo taxonomical tool and search for potentially useful compounds. The subsp. greuteri and carbonellii

Buildup of Abiotic Oxygen and Ozone in Moist Atmospheres of Temperate Terrestrial Exoplanets and its Impact on the Spectral Fingerprint in Transit Observations [PDF]
We investigate the abiotic production of oxygen and its photochemical byproduct ozone through water vapor photolysis in moist atmospheres of temperate terrestrial exoplanets. The amount of water vapor available for photolysis in the middle atmosphere of a planet can be limited by an atmospheric cold-trap, the formation of which largely depends on the ...

The impact of abiotic factors on cellulose synthesis.
As sessile organisms, plants require mechanisms to sense and respond to changes in their environment, including both biotic and abiotic factors. One of the most common plant adaptations to environmental changes is differential regulation of growth, which

By employing a combination of single cell and spatial transcriptomic sequencing, this study presents a stereoscopic response of rice leaf to Magnaporthe oryzae infection. The vascular tissues mount defenses by producing phytoalexins. The immune strength is stronger toward the rice leaf tip than that of the leaf base.

Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

The Evolution of Multicomponent Systems at High Pressures: IV. The Genesis of Optical Activity in High-density, Abiotic Fluids [PDF]
A thermodynamic argument has been developed which relates the chirality of the constituents of a mixture of enantiomers to the system excess volume, and thereby to its Gibbs free enthalpy. A specific connection is shown between the excess volume and the statistical mechanical partition function. The Kihara-Steiner equations, which describe the geometry

In early cold response, MdICE1L utilizes MdHB7L as a cofactor to facilitate the transcriptional activation of MdCBFs, thereby activating cold signaling rapidly and strongly. Subsequently, MdICE1L is degraded by MdHOS1. Meanwhile, MdHB7L is released and accumulates.

Among-site variability in the stochastic dynamics of East African coral reefs [PDF]
Coral reefs are dynamic systems whose composition is highly influenced by unpredictable biotic and abiotic factors. Understanding the spatial scale at which long-term predictions of reef composition can be made will be crucial for guiding conservation efforts.
