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 …

Molecular Phylogeny And Biogeography Of The South American Genus Metrodorea (Rutaceae), Pedro Dias, Renata Giassi Udulutsch, Jose Rubens Pirani
Turkish Journal of Botany
The genus Metrodorea (Rutaceae), with 6 species, has representatives that vary from small shrubs to tall trees, and its leaf sheaths make it unique in the family; it is restricted to South America, with species diversity concentrated in Brazil. In this study, we applied Bayesian and parsimony methods to infer the molecular phylogeny of Metrodorea, and cladistic biogeographic methods to propose an area cladogram for the genus. All results supported Metrodorea as monophyletic, and the presence of leaf sheaths is reinforced as its key diagnostic feature. Bayesian and parsimony trees were identical for relationships within Metrodorea. The crown clade (M. …

Turkish Journal of Botany
Mediterranean-type communities of the Sinop Peninsula were classified as plant functional types (PFTs) by the help of some vegetative and generative traits and 5 PFTs were determined. Some vegetative (specific leaf area (SLA), leaf texture, leaf P concentration, deciduousness, hairiness) and generative (reproductive phenology and fruit type) traits were found to be significant for discrimination of PFTs. It was found that PFT3 and PFT4 were associated with leaf texture, SLA, and leaf P concentration. PFT2 was associated with deciduousness, hairiness, and reproductive phenology, while PFT1 was only associated with fruit type. Generative traits were found to be associated with PFT1 …
