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 …

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.

A Novel Phytoene Synthase Paralog From Halophytic Salicorniaconfers Salinity Tolerance In Plants, Nazia Rehman, Muhammad Ramzan Khan, Ghulam Muhammad Ali
Turkish Journal of Botany
Salicornia seems to be a suitable euhalophyte for the study of salt stress resilience mechanism and exploitation of salinity-tolerant genes for crop yield improvement. In this study, we cloned a novel SePSY1 gene from an extremely salt-tolerant glycophyte, Salicornia europaea. The sequence analysis revealed that the newly isolated gene is a paralog of PSY, suggesting a gene duplication event in Salicornia. The newly isolated gene encodes a protein of 419 amino acids. The C-terminus containing a Trans-IPPS-H domain with catalytic and binding regions exhibits considerable conservation in various species, while the N-terminus remained divergent. The structural analysis suggested a catalytic …
