AI Article Synopsis
- A new nematode species (n. sp.) was discovered in the Siahkal forests of Northern Iran, with specific characteristics like body length and tail shape.
- The species has key morphological features that allow it to be compared to eight other known species within its genus.
- Genetic analysis reveals that this new species is distinct from others, sharing certain traits with its closest relatives, particularly regarding the position of the excretory pore.
Article Abstract
A new species of the genus , n. sp. collected from Siahkal forests of Northern Iran, is described and illustrated. The new species is characterized by its 314 to 422-µm-long body, eight incisures in the lateral field, 7.5 to 8.0-μm-long stylet, position of the excretory pore, at the level of the hemizonid, both posterior to the nerve ring 61 to 76 µm from the anterior end, and conical tail with pointed tip. Based on morphology and morphometrics, the new species can be compared with eight known species of the genus: . , . , . , . , . , , , and . Evolutionary relationships of the new species with other species were assessed with sequences of the D2 to D3 expansion regions of 28S rRNA and partial 18S rRNA gene. The phylogenetic analysis showed that . n. sp. is genetically distinct from other included species. n. sp. is a member of the species complex and close to . , . , and . . Typologically, these species share the relative position of the excretory pore to the hemizonid.

Background: Interactions between RNA-binding proteins and RNA regulate RNA transcription during osteoporosis. Ferroptosis, a programmed cell death caused by iron metabolism, plays a vital role in osteoporosis. However, the mechanisms by which RNA-binding proteins are involved in ferroptosis during osteoporosis remain unclear.

Heat stress poses a significant challenge for maize production, especially during the spring when high temperatures disrupt cellular processes, impeding plant growth and development. The B-cell lymphoma-2 (Bcl-2) associated athanogene (BAG) gene family is known to be relatively conserved across various species. It plays a crucial role as molecular chaperone cofactors that are responsible for programmed cell death and tumorigenesis.

Background: Nitrogen (N) deposition has become a major driving factor affecting the balance of terrestrial ecosystems, changing the soil environment, element balance and species coexistence relationships, driving changes in biodiversity and ecosystem structure and function. Human-induced nitrogen input leads to a high NH/ NO ratio in soil. However, relatively few studies have investigated the effects of different nitrogen sources on forest plant-microbial symbionts.
