Turkish Journal of Botany

The study of endemic species provides valuable perspectives on evolutionary history and future targets for their conservation. Salix purpurea L. subsp. leucodermis Yalt., which is endemic to Sandras Mountain in Türkiye, was analysed using morphological, anatomical, and genomic methods. This study presents the first draft short-read sequence of S. purpurea subsp. leucodermis, providing preliminary genomic evidence of differentiation from related taxa. This study also revealed a specific combination of anatomical features (prominent calcium oxalate crystals and amphistomatous leaves) and morphological characteristics (striated wood, glabrous buds, absence of stipules) that differentiate the taxon in question from the closely related species S. …

What Are Vestigial Structures? Evidence For Evolution Explained, Ryan Bebej

University Faculty Publications and Creative Works

Evolution wasn’t something we talked about very much in my home or church when I was growing up.

Yet somehow, I came to believe that evolution wasn’t compatible with Christian faith. At the time that seemed okay, because I had heard that the evidence for evolution wasn’t very strong anyway.

That all began to change when I started studying biology in college. In different classes, I encountered some of the compelling evidence for evolution and common descent.

Vestigial structures were one of the topics that came up often in biology textbooks about these topics.

Today, biologists point to …

Water-Driven Reactivation Of Photosystem Ii In Plagiochasma Appendiculatum, Vineet Soni, Upma Bhatt, Yashwant Sompura

Turkish Journal of Botany

Plagiochasma appendiculatum, a desiccation-tolerant liverwort, offers a unique system for unraveling the biophysical dynamics of photosynthetic recovery upon rehydration. This study employed high-resolution chlorophyll a fluorescence (ChlF) kinetics to clarify the sequential reactivation of photosystem II (PSII) during the desiccation-to-rehydration transition. Upon desiccation, the OJIP transient collapsed into a linear trace, indicating complete photochemical arrest and inactivation of PSII reaction centers (RCs). Rehydration triggered a biphasic recovery, including an initial rapid phase (0–30 min) marked by sharp increases in F0 and Fm , indicative of PSII–LHCII supercomplex reassembly and thylakoid membrane restoration, followed by a stabilization phase (30–125 min) wherein …

Longitudinal Patterns In Stygobiont Distribution In The Hyporheic Zone Of The Karst Spring-Fed San Marcos River, Texas, Usa, Kenneth Sparks, Benjamin F. Schwartz, Safra Altman, Kathryn E. Perez, Zoey B. Chanin, Caroline Mierzejewski, Benjamin T. Hutchins

School of Integrative Biological & Chemical Sciences Faculty Publications

Groundwater-obligate taxa (stygobionts) exhibit variable degrees of habitat specialization, ranging from those restricted to single micro-habitats to generalists occurring in a broad range of habitat types. The karstic Edwards Aquifer is the most biodiverse and well-studied groundwater habitat in the continental United States, but some Edwards Aquifer-associated species also occupy the hyporheic zone of rivers downstream from karst. The goals of this research were to 1) assess the potential of the off-karst hyporheic zone as habitat for ‘karst’ species and 2) to determine how stygobiont richness, diversity, and abundance related to distance from karst in the hyporheic zone of a …

Unveiling The Diversity Within Salvia Caespitosa Sensu Lato (Lamiaceae): Three New “Hidden” Endemic Species From Türkiye​, Ferhat Celep, Musa Doğan, Gali̇p Akaydin, Ahmet Kahraman, Ersi̇n Karabacak, Ömer Çeçen, Meti̇n Armağan, Chun-Lei Xiang, Bryan T. Drew

Turkish Journal of Botany

Documenting species, particularly those that are threatened or endangered, is fundamental to biodiversity conservation. However, many taxa remain scientifically unrecognized, being either undiscovered or unpublished. While some plants can be easily recognized as new species, other identifications are obscured by morphological, taxonomic, and nomenclatural complexity. Detecting cryptic or “hidden” species is therefore essential to understanding biodiversity and plant evolution. Our revisionary studies on Salvia demonstrate that the morphologically complex Salvia caespitosa is not a single species but instead comprises at least four distinct species, three with narrow distributions. This conclusion is supported by integrative evidence from extensive field studies, herbarium …

Turkish Journal of Botany

Divalent cations, particularly calcium (Ca2+) and magnesium (Mg2+), are essential for maintaining chromosomal architecture, yet their roles in plants remain poorly characterized. This study investigated the effects of Ca2+ and Mg2+ on the chromosomal structure of wheat (Triticum aestivum, 2n = 6x = 42), a widely used model in plant cytogenetics. Root-tip chromosomes were isolated enzymatically and treated with BAPTA (a Ca2+-specific chelator), EDTA (a broad cation chelator), and buffer solutions containing either 5 mM Mg2+ (XBE5) or no Mg2+ (XBE). Chromosomes were stained with aceto-orcein for light microscopy and processed for scanning electron microscopy (SEM). Microscopic observations revealed that …
