Turkish Journal of Botany
The phylogeny of Astragalus L. section Anthylloidei DC. and its interrelationship with allies were examined. The study was conducted using nrDNA ITS and plastid rpl32-trnL_{(UAG)} sequences. Astragalus sect. Anthylloidei is nonmonophyletic, and its members are scattered across the tree in 4 well-supported clades and intermixed with members of other spiny sections. All the multispecific informal groups of the section, with the exception of A. murinus Boiss. group, are not monophyletic. Morphological character evolution was mapped on the molecular tree. Our results suggest that morphology cannot elucidate infrageneric relationships in spiny Astragalus accurately; analyzed characters have evolved several times in sect. …

Flower Closure In The Field Bindweed (Convolvulus Arvensis): A Field Test Of The Pollination Hypothesis, Pavol Prokop, Dominika Neupauerova
Flower Closure In The Field Bindweed (Convolvulus Arvensis): A Field Test Of The Pollination Hypothesis, Pavol Prokop, Dominika Neupauerova
Turkish Journal of Botany
Although the behavioral plasticity of flower traits has received considerable attention, its adaptive value is not thoroughly understood. We experimentally examined flower opening/closure in field bindweed (Convolvulus arvensis), a species with short flower persistence (1 day) in which adaptive responses to pollination were not previously expected. In line with the pollination hypothesis we suggested that flower exposure in this species should respond to pollination. More specifically, we predicted that flower closure in the pollinated flowers would be quicker than that in unpollinated flowers. As predicted, the unpollinated flowers were open for a longer time than the pollinated flowers. There was …

Subcellular Localization And Developmental Regulation Of Cytosolic, Soluble Pyrophosphatase Isoforms In Arabidopsis Thaliana, Zahi̇de Nesli̇han Öztürk, Steffen Greiner, Thomas Rausch
Turkish Journal of Botany
Pyrophosphate (PP_{I}) is the by-product of several reversible key reactions of primary metabolism. Thus, generated PP_i should be removed by hydrolysis via pyrophosphatases to prevent accumulation and to drive anabolism. In plastids, a plastidic, soluble pyrophosphatase splits PP_i released by ADPG pyrophosphorylase. The cytosolic PP_i pool is believed to be hydrolyzed by tonoplast- and/or Golgi-integral H^{+}-translocating pyrophosphatases. The Arabidopsis thaliana (L.) Heynh. genome encodes 6 soluble pyrophosphatase isoforms (PPas), 1 of which was shown to be localized in plastids. The remaining 5 of those PPas (PPas 1-5) are more similar to each other with highly conserved protein sequences. They all …
