Comparison of Photosynthetic Pigment Contents of the resurrection Plants <i>Ramonda serbica</i>and <i>Ramonda nathaliae</i>of Some Different Populations from Kosovo, Albania and Macedonia

引用

American Journal of Plant Sciences 2012年第11期3卷 1588-1593页

作者： Bekim Gashi Kasamedin Abdullai Efigjeni Kongjika Department of Biology Faculty of Mathematics and Natural Sciences University of Pristina Pristina Republic of Kosovo Section of Natural and Technical Sciences Academy of Sciences of Albania Tirana Albania

The resurrection plants Ramonda serbica and Ramonda nathaliae are the physiological model plant and endemic species from Balkan Peninsula. Study was carried out to assess the impact of different populations on photosynthetic pigment contents and their effect on physiological activity of these species. The experiment was conducted with leaves of R. serbica collected from nine populations in Kosovo, three in Albania and two in Macedonia, while for R. nathaliae four populations in Macedonia. For this purpose plants after collection from their natural populations were kept for 24 hours at constant temperature and humidity and in natural photoperiod. According to our data the pigment contents (Total chl + Carot) of R. serbica, measured as mg per gram dry weight (DW), were higher (7.06 mg·g-1 DW) in Radaci populations (Kosovo) and lower (4.63 mg·g-1 DW) in Jukniu Mountain-Kruja (Albania). On the other hand, the higher (5.28 mg·g-1 DW) of pigment contents (Total chl + Carot) of R. nathaliae were observed in Vorca populations and the lower (4.24 mg·g-1 DW) in Kaparll?k populations. Ratio chlorophyll a/b of R. serbica in Kruja Castle populations from Albania was the higher (3.68) comparing with Zhlebi populations from Kosovo (1.68). Similarly in case of R. nathaliae the higher (3.36) value was in Kaparll?k populations and the lower (3.12) in Matka populations. The data obtained were further analyzed using one-way ANOVA and a significant change was recorded in the different populations. These studies clearly indicate that the Ramonda plants from different ecological habitats there have been changes of photosynthetic pigment contents.

A Footprint of Plant Desiccation Tolerance. Does It Exist？

引用

Molecular Plant 2018年第8期11卷 1003-1005页

作者： Henk W.M. Hilhorst Maria-Cecilia D. Costa Jill M. Farrant Laboratory of Plant Physiology Wageningen University and Research Droevendaalsesteeg 1 Wageningen 6708 PB the Netherlands Department of Molecular and Cell Biology University of Cape Town Private Bag Rondebosch Cape Town 7701 South Africa

Desiccation tolerance （DT）, the ability to survive loss of more than 90% of cellular water （≤0.1 g H2O g^-1 dry mass） for prolonged periods, is common in seeds （90% of angiosperm species） but rare in vegetative tissues （0.04% of land plants; reviewed in Gaff and Oliver, 2013）. Vegetative DT is more widespread in non-tracheophytes, being present in 25 species of algae, 158 bryophytes species, and all lichens, but is rare in tracheophytes, being displayed in 64 pteridophyte and 135 angiosperm species （Gaff and Oliver, 2013）.

论“复活”作为列夫·托尔斯泰的生死修辞

外国文学研究 2021年第2期

“复活”作为列夫·托尔斯泰总结性长篇小说的书名，它的多重含义，是人人皆知的。1910年冬天，托尔斯泰离家出走，演绎了另一种复活概念，展示了托尔斯泰创造的对生命实体本身的“生死修辞”。然而早在19世纪80年代，托尔斯泰在对《福... 详细信息

“复活”作为列夫·托尔斯泰总结性长篇小说的书名，它的多重含义，是人人皆知的。1910年冬天，托尔斯泰离家出走，演绎了另一种复活概念，展示了托尔斯泰创造的对生命实体本身的“生死修辞”。然而早在19世纪80年代，托尔斯泰在对《福音书》做了充分研究之后，就已经对“复活”概念有了专门论述。他认为，《福音书》中的“复活”事件，仅仅是福音书作家的讲述，是一种为了传播真理而臆造的修辞。但是，在自己的小说《复活》中，托尔斯泰显然赋予这个概念多重的含义：它显然明确指向小说的主题——一个俄罗斯贵族的忏悔及复活；它显然也暗喻了《福音书》中描绘的基督的复活事件；它明显关联复活节；它也绝非仅仅是思想层面的复活而是自然界最真实生动的复活；它还是实存生命体的复活。而托尔斯泰最后的生命历程，恰恰实现了托尔斯泰本人对生命复活的预言。因此，在托尔斯泰的概念、小说和实际行动中，“复活”概念，在“灵”和“物”的多重关系中，构成了他的最大的生命修辞。
