A Comparative Analysis Of Membrane Intactness And Genome Integrity In Pea,Barley, And Wheat In Response To Uvc Irradiation, Mariyana Georgieva, Ivelina Nikolova, Georgi Bonchev, Zornitsa Katerova, Dessislava Todorova
Turkish Journal of Botany
The maintenance of plant genome integrity plays a critical function in the processes of DNA replication, transcription, and repair. Short-wave UV radiation (UVC) is among the most harmful agents known to affect genome stability and to induce DNA damage, including double-strand breaks (DSBs). Most previous studies in plants addressed the effects of UVC radiation at the physiological level; however, little research effort has been put into genome sensitivity across different plant species. Here, we made use of the trypan blue exclusion test and neutral comet assay to assess nuclear membrane and genome integrity in response to UVC radiation in monocot …

Overexpression Of A Soybean Expansin Gene, Gmexp1, Improvesdrought Tolerance In Transgenic Tobacco, Thanh Son Lo, Hoang Duc Le, Vu Thanh Thanh Nguyen, Hoang Ha Chu, Van Son Le, Hoang Mau Chu
Turkish Journal of Botany
The EXP1 gene encodes expansin, which has the ability to loosen the plant cell wall. The soybean expansin gene GmEXP1 is activated specifically during the root elongation process, and thus it plays important roles in root development. During the drought period, changes in pressure within the cell and the fast development of the root allow plants to collect water from deep soil, which in turn helps plants grow and develop. In this study, we have successfully cloned and generated a GmEXP1 construct expressing recombinant expansin protein in tobacco plants. GmEXP1 is expressed in transgenic tobacco plants and passed on to …
Aquaporins As Targets For Stress Tolerance In Plants: Genomic Complexity And Perspectives, Wonkeun John Park, Benjamin Todd Campbell
Aquaporins As Targets For Stress Tolerance In Plants: Genomic Complexity And Perspectives, Wonkeun John Park, Benjamin Todd Campbell
Turkish Journal of Botany
As a multigene family, plant aquaporins function not only in water transport but also in transport of small elements that are important for vegetative and reproductive growth of plants. Increasing evidence exhibits the relevance of aquaporins to tolerance against abiotic and biotic stresses such as drought, nutrient deficiency, and herbivore attack. With the accumulation of crop genome sequencing, it is suggested that several aquaporin genes are conserved in subchromosomal locations as tandem duplicated members. In this review, we will discuss the compelling nature of aquaporins as multifunctional transport channels that are often encoded in clustered regions of genomes and relevant …

Towards A New Classification Of Salvia S.L.: (Re)Establishing The Genus Pleudia Raf., Maria Will, Natalie Schmalz, Regine Classen-Bockhoff
Turkish Journal of Botany
Salvia L. İn its traditional circumscription is the largest genus within the mint family. To date, the magnitude of the task has rendered it difficult to provide a genus-wide revision based on morphological data. Current molecular investigations based on a dense taxon sampling representing the whole phenotypic diversity and distribution range of Salvia confirmed that the genus is polyphyletic. Salvia species fall in 4 distinct clades, although all of them, except Clade IV, also include non-Salvia genera. A taxonomic revision is thus urgently needed with two different approaches that have to be considered: (1) to include the 5 morphologically distinct …
