The relationship between fruit development and the proliferative capacities of inflorescence meristems has been examined in Arabidopsis thaliana. In the wild-type Landsberg erecta (Ler) line, flower production ceases coordinately on all inflorescence branches by a process we have designated global proliferative arrest (GPA). Morphological studies indicate that GPA involves a cessation of prolif...

The weed seed bank of a long-term tillage study in subarctic Alaska was studied at the end of 10 years of continuous spring barley (Hordeum vulgare L.). Tillage treatments were: no-till, disked once (spring), disked twice (spring and fall), and chisel plow (fall). Soil cores were obtained from each tillage treatment and seeds were manually separated from soil after washing through sieves. Tilla...

This research explores the growth performance of three potential medicinal plants namely, Bajradanti (Potentilla flugens), Chutro (Breberisaristata), and Timur (Xanthoxylumarmatum) cultivated at nursery of Institute of Forestry with the application of tunnel, shaded and open beds treatment each with 4.0 m x 1.0 m size and constant supportive facilities of manure, irrigation and care. From the m...

New host plant records are given for six Empria species from Japan. They are Rosa multiflora [Rosaceae] for E. honshuana Prous & Heidemaa, 2011, Rubus sp. [Rosaceae] for E. japonica Heidemaa & Prous, 2011, Geum japonicum and G. calthifolium var. nipponicum [Rosaceae] for E. loktini Ermolenko, 1971, Rosa multiflora, Potentilla indica and probably Rubus parvifolius [Rosaceae] for E. quadrimaculat...

The study aims to investigate the effects of n-butanol extraction of Potentilla anserina L. (NP) on cortical neuronal cultures and subject to 2h of oxygen deprivation hypoxia-like injury. The investigation demonstrated that NP at 2, 1 and 0.5 mg/ml effectively prevented the decrease of neuron survival rates and the increase of LDH release after exposure of cortical cultures to 2h-oxygen depriva...

Medicinal plants used during the plague described in Herbarium of Simon Syrenius (1613) Before effective methods treatment and prevention infections all other infectious diseases were known, attempts made to treat them with natural means. The blight, among others considered following plants: angelica (Angelica archangelica), valerian (Valeriana officinalis), pimpinella, (Pimpinella sp.) common ...

Ecologists are searching for models, frameworks, and principles that provide a bridge between theory and the practice of restoration. Successional management has been proposed as a useful model for managing and restoring invasive-plant-dominated rangeland because it provides a framework in which ecological processes can be manipulated by managers to achieve a desired plant community. Succession...

Superoxide dismutase (SOD) is a critical enzyme associated with controlling oxygen toxicity arising out of oxidative stress in any living system. A hyper-thermostable SOD isolated from a polyextremophile higher plant Potentilla atrosanguinea Lodd. var. argyrophylla (Wall. ex Lehm.) was engineered by mutation of a single amino acid that enhanced the thermostability of the enzyme to twofold. The ...
