Phylogenetic Analyses Of Amaranthaceae Based On Matk Dna Sequence Data With Emphasis On West African Species, Oluwatoyin T. Ogundipe, Mark Chase
Phylogenetic Analyses Of Amaranthaceae Based On Matk Dna Sequence Data With Emphasis On West African Species, Oluwatoyin T. Ogundipe, Mark Chase
Turkish Journal of Botany
Comparative sequencing of the chloroplast matK coding and non-coding regions was used to examine relationship among the species of Amaranthaceae with emphasis on the West African species and other closely related family such as Chenopodiaceae, Portulacaceae, and Caryophyllaceae. Phylogenetic analysis of the matK sequences alone and in combination using maximum parsimony methods produced monophyletic lineage of Amaranthaceae-Chenopodiaceae. Our results indicated that a polyphyletic Celosieae as sister to an Amaranthus-Chemissoa lineage. Subfamily Amaranthoideae is paraphyletic to the core Gomphrenoids. This study also shows that the polyphyly of Amarantheae is apparent and so is the polyphyly of Amaranthinae.

Study Of Seasonal Influences On Algal Biodiversity In The River Yarqon (Central Israel) By Bio-Indication And Canonical Correspondence Analysis (Cca), Sophia Barinova, Moti Tavassi
Turkish Journal of Botany
In our research conducted in the River Yarqon during 2003-2006, we identified 313 taxa of algae and cyanobacteria belonging to 8 taxonomical divisions. Out of these 313 taxa, 268 taxa (85.6%) were indicators of environmental conditions that characterised the river water as alkaline with medium mineralisation. In the rainy and dry seasons the algal taxonomic compositions were very different, with prevailing diatoms in the winter and cyabobacteria and greens in summer. Bio-indication shows that the taxonomic preference for the self-purification process was more intensive during the rainy season, while the low level of river water in the dry season stressed …

Reed – Periphyton – Mycota Interactions In The Water Of Different Water Bodies, Bazyli Czeczuga, Bozenna Mazalska, Anna Godlewska, Elzbieta Muszynska
Turkish Journal of Botany
The authors investigated the influence of periphyton that abundantly overgrow stalks of reeds (reed-periphyton) submerged in water [Phragmites australis (Cav.) Trin. ex Stewdel], especially the old ones, on the occurrence of mycoflora species in different trophic seasons in the water of 4 trophically different water bodies. The seeds and snake exuviae were used as bait. In the spring, diatoms were the predominant group of algae forming the periphyton on old reed stalks, green algae predominated in the summer, and cyanobacteria in the autumn. During the seasons studied, in the water from Lake Blizno equal numbers of mycoflora species were noted …
Dynamics Of 2,4-D In Generation Of Cytomorphological Variants In An Important Anticancerous And Antihepatotoxic Herb – Cichorium Intybus L., Zeba Khan, Mohammad Yunus Khalil Ansari, Honey Gupta, Sana Chaudhary
Dynamics Of 2,4-D In Generation Of Cytomorphological Variants In An Important Anticancerous And Antihepatotoxic Herb – Cichorium Intybus L., Zeba Khan, Mohammad Yunus Khalil Ansari, Honey Gupta, Sana Chaudhary
Turkish Journal of Botany
The genotoxic effect of 2,4-D was investigated in chicory (2n = 18). At 100 ppm concentration 4 variants differing in morphological traits were isolated and subjected to chromosomal analysis. Morphological variations in shape, height, and yield parameters were observed. Different cytological anomalies such as univalents, multivalents, bridges, laggards, chromosome stickiness, and polyads occurred in all 4 isolates. However, the frequency of these chromosomal irregularities decreased at anaphase, exhibiting recovery at later stages. Thus the above concentration of growth hormone 2,4-D can be effectively incorporated for raising viable mutants in this medicinally useful herb.

Turkish Journal of Botany
The effect of plant growth regulators (PGRs) and carbohydrate sources on callus induction, callus growth, and plant regeneration in foxglove was examined. Explants were transferred onto MS medium with various levels of PGRs and carbohydrates to determine the optimum explant and effective combinations of PGR treatment. For callus induction 6.0 mg L^{-1} of \alpha-naphthalene acetic acid (NAA) and 3.0 mg L^{-1} of benzyl-aminopurine (BA) were very responsive. Addition of cytokinins (BA and kinetin) at 0.5-3.0 mg L^{-1} to media containing NAA enhanced callus growth. Shoot regeneration was best achieved in MS + 6.0 mg L^{-1} of BA. Adenine sulphate (Ade) …

The Role Of Polyethylene Glycol (Peg) Pretreatment In Improving Sugarcane’S Salt (Nacl) Tolerance, Neelma Munir, Faheem Aftab
Turkish Journal of Botany
An important aspect of salt tolerance studies in different plants is the relationship between salt and water stress. In the present study calluses (60 days old) of 2 sugarcane cultivars (cv. SPF 234 and cv. HSF 240) were treated with 4 different salt concentrations, including a control (0 mM NaCl), after 1% polyethylene glycol (PEG) pretreatment for 5 days. Fresh weight, callus browning, and necrosis data were recorded at day 120. Biochemical parameters (soluble protein contents, and peroxidase, catalase, and superoxide dismutase activity) were also analysed. Regardless of PEG pretreatment, calluses subjected to salt stress had less fresh weight than …
