Gamma Irradiation Enhancement Of Biofilm Production In Bacillus Amyloliquifaciensand Effect Of Mutants' Inoculation On Apx1 Expression In Salt-Stressed Egyptian Barley, Reda Gaafar, Wedad Kasim, Rania Abou-Ali, Mohamed Omar, Heba Hewait
Turkish Journal of Botany
Gamma rays are known to induce random mutations, which are used to enhance the production of biofilms in bacteria. Therefore, to improve the activity of biofilm formation in wild Bacillus amyloliquefaciens (HM6), this bacterial strain was mutated using five doses of gamma irradiation. Sixteen mutants and their wild strain B. amyloliquefaciens (HM6) were tested for biofilm formation under two different (250 and 350 mM) NaCl concentrations. Only six mutants exhibited a significant increase in biofilm formation under 350 mM NaCl. Inoculation of salt-stressed Giza123 barley seedlings with the two mutants (M1 and M7), which showed distinguishable rep-PCR patterns, and their …

Plant Community Response To Disturbances In Nebraska Sandhills Upland Prairie, Josiah D. Dallmann
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Historically, disturbances shaped prairie ecosystems both directly through events like fire and soil moving by animals, as well as indirectly through dynamic rainfall patterns and periodic flux in seed availabilities. We hypothesized that the implementation of several distinct disturbance events in Nebraska Sandhills upland prairie would have measurable effects on plant community composition. We implemented mid-spring fire, soil disturbance in the form of disking, seed addition of native forbs on disked plots, as well as early summer supplemental watering (to mimic minor rainfall events during abnormally dry periods) during 2016 and 2017. Plant community response during the first and second …

Turkish Journal of Botany
Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA−trnH, trnL−trnF, and trnS−trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range. The levels of haplotype and nucleotide diversity varied in the range of 0.133−0.911 and 0.0002−0.0059, respectively. The highest values of these parameters are characteristic of populations located in the Barguzin depression. Variable sites detected within the intergenic spacers allowed the identification of eleven haplotypes; nine of them were found in the populations from the Barguzin depression …

Properties, Variations, Roles, And Potential Applications Of Epicuticular Wax: A Review, Priyal Sharma, Shankar Lal Kothari, Mahender Rathore, Vinod Gour
Turkish Journal of Botany
The cuticular wax layer covers the aerial surface of plants and acts as a barrier between plants and the environment. The cuticle plays a key role in the protection of plants from pathogens, UV light, and transpiration. Variation in the wax quality and quantity is influenced by factors like the solvent used for extraction, species, ontogeny, and season. Compounds isolated from the cuticle layer have been studied by various methods and were found to play an important role from the ecological and physiological points of view. These compounds include esters, alcohols, ether, alkane, and aldehydes. Nonpolar compounds help reduce water …
Phenotypic Evaluation Of Transgenic Peas (Pisum Sativum L.) Harboring Atnhx1 Demonstrates Stable Gene Expression And Conserved Morphology In Subsequent Generations, Zahid Ali, Wajeeha Saeed, Saadia Naseem, Faheem Ahmad, Ahmed Akrem, Nighat Yasmeen, Hans Joerg Jacobsen
Turkish Journal of Botany
In recent years, transgenic approaches have played a significant role in improving traits that help plants overcome abiotic stresses. Combined gene discovery and functional genomics have helped identify diversified mechanisms and gene families, which improved productivity under various abiotic stresses. We report on the genetic stability and persistent morphological features of transgenic pea (Pisum sativum L.) plants harboring the dicistronic vector construct pG0229MASnhx1/luc over five generations. In addition to salt stress tolerance, the transgenic plants showed frost tolerance compared to wild-type (WT) plants. Frost tolerance of AtNHX1 transgenic pea plants was unexpected and needs further investigation. We report morphological and …

Notes On The Genus Frondaria (Orchidaceae) With Description Of New Species, Dariusz Szlachetko, Marta Kolanowska, Max Rykaczewski
Turkish Journal of Botany
The specific diversity of Neotropical orchid genus Frondaria is evaluated based on morphological data. Frondaria was considered a monospecific taxon for years; however, our recent studies on Andean orchids indicated that it is actually much more variable. Within Colombian material, we found a species which does not fit the morphological description of F. caulescens and described it here as a new species named F. colombiana . The novelty is characterized by inflorescence being three times as long as the ramicaul, the tridentate leaf apex with middle tooth as long as lateral ones, papillate apices of sepals, and oblong-ligulate lip middle …
