AI Article Synopsis
- A study on the Anthemissect.Hiorthia plants in Kriti, Greece, discovered three endemic species, each with different ploidy levels based on a haploid number of 9.
- The species with the broadest distribution is tetraploid, while another local endemic is decaploid, making it the highest ploidy recorded in the region.
- A new distinct population found on Mt. Kedros is hexaploid and described as a new species; polyploidy may serve as a reproductive barrier, helping these mountain species adapt and evolve in isolation.
Article Abstract
A morphological and karyological investigation of the Anthemissect.Hiorthia representatives of Kriti (Greece) revealed that three different species are found on the island, all endemic, and each characterised by a different ploidy level based on the haploid series of = 9. , the species with the widest distribution, is tetraploid with 2 = 4 = 36. , a local endemic of the Lefka Ori, was found being decaploid, with 2 = 10 = 90, the highest number ever recorded in The recently discovered population on Mt. Kedros (south-central Kriti) is morphologically distinct from all the entities growing on Kriti; it also differs from the variable and widespread group. It is here described as a new species, Goula & Constantinidis. It is a hexaploid, with 2 = 6 = 54. All chromosome numbers are reported for the first time. Polyploidy might have acted as a reproductive barrier among these perennial species, complementing isolation by spatial distance and evolutionary divergence. Further, it might have contributed adaptation advantages to these three predominately mountain species.

Plant-parasitic nematodes pose a significant threat to crop production, impacting agricultural yields. In the search for new nematicides, a series of 1,2,4-oxadiazole-5-carboxylic acid derivatives containing amide or ester groups were designed and synthesized using an activity-based approach. Bioassay results showed that some compounds exhibited good nematicidal activity against , , and .

Large Stokes shift red fluorescent proteins (LSS-RFPs) are of growing interest for multicolor bioimaging applications. However, their photochemical mechanisms are not fully understood. Here, we employed the QM(XDW-CASPT2//CASSCF)/MM method to investigate the excited-state proton transfer and photoisomerization processes of the LSS-RFP mKeima starting from its cis neutral isomer.

The structure of the novel photoactive nickel species was simulated by density functional theory (DFT)/time-dependent density functional theory (TD-DFT) calculations. The application of the simplified photoactive nickel catalyst was demonstrated in a photoinduced nickel-catalyzed three-component arylsulfonation of 1,6-enynes. This reaction was autopromoted and proceeded in the absence of an additional photocatalyst.
