Site Conditions And Functional Traits Affect Regeneration Dynamics Of European Hornbeam (Carpinus Betulus L.) In Forest Canopy Gaps, Éva Salamon-Albert, Ágnes Csiszár, Dénes Bartha
Turkish Journal of Botany
European hornbeam is a deciduous tree in mixed forest ecosystems, making a valuable contribution to species richness at a community level. We investigated early-phase regeneration of saplings in canopy gaps under contrasting ecological conditions by analyzing relationships between site parameters, leaf nutrients, and light-regulated carbon and water exchange functions at ecosystem and forest levels. Using plant response variables, we also detected functional soft traits and trade-offs. Species abundance proved to be affected by the elevation and slope of the sites, air humidity, precipitation during the growing period, as well as light-dependent and light-saturated rate of the assimilation function. Relationship between …

Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya
Turkish Journal of Botany
Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast …

Relationships Between Sorghum Bicolor (Poaceae) And Its Closerelatives Based On Genomic In Situ Hybridization Evidence, Qing Liu, H L, Jun Wen
Relationships Between Sorghum Bicolor (Poaceae) And Its Closerelatives Based On Genomic In Situ Hybridization Evidence, Qing Liu, H L, Jun Wen
Turkish Journal of Botany
Sorghum bicolor (L.) Moench (sorghum) is a naturally well-established diploid species with 2n = 2x = 20. Here we provide evidence to identify the genomic relationships of S. bicolor and its extant relatives using genomic in situ hybridization. The genomic divergences between S. bicolor and its close relatives may be presented as: S. bicolor-S. x drummondii (Nees ex Steud.) Millsp. & Chase < S. bicolor-S. x almum Parodi < S. bicolor S. arundinaceum (Desv.) Stapf < S. bicolor-S. propinquum (Kunth) Hitchc. Sorghum arundinaceum probe signals showed spotted or painted patterns on the S. bicolor chromosomes, indicating that the degree of genomic divergence between S. bicolor and S. arundinaceum is distinct. It is reasonable to infer that S. bicolor might have diverged from S. arundinaceum in the early diversification history of the subgenus. The probe signal intensity of S. arundinaceum and S. propinquum is greater on the 17 chromosomes than on the remaining 23 chromosomes of S. halepense (L.) Pers., whereas S. bicolor and S. propinquum probes produced spotted or patchy signals on the 40 S. halepense chromosomes. Therefore, the degree of genomic divergence may be presented as: S. halepense-S. bicolor < S. halepense-S. arundinaceum < S. halepense-S. propinquum.

Floristic Differentiation Between Mid-Seral Communities Of Abandonedcharcoal Kilns In The Forests Of The Gargano Promontory (South Italy), Franco Pedrotti, Dan Gafta
Turkish Journal of Botany
We searched for patterns in species composition and richness of mid-seral communities developed on abandoned charcoal hearths that might be induced by differences in succession progress and forest context. One phytosociological relevé was performed on each of the 22 charcoal platforms located in beech (Anemono apenninae-Fagetum) and oak-hornbeam forests (Doronico-Carpinetum). The ratio of forest understorey to non-forest species richness (F/nF) at plot level was used as a proxy for the succession progress. There was a sharp differentiation of plant communities due to their floristic resemblance with the understory vegetation of the forest type in which they were integrated. Nevertheless, these …
