On the occasion of having collected three gravid Geochelone carbonaria in the Bolivian Chaco, data are given on oviducal eggs, as well as on five shells of eggs of the same species in the Museum collection. A review of the literature on the reproduction of G. carbonaria and of its sibling G. denticulata is presented, with an elementary statistical treatment of the data on number of clutches per...
This chapter synthesizes our current knowledge on the ecological genetics of the model legume Medicago truncatula. After a short introduction to the life cycle of the species, we describe the mating system of M truncatula and how selfing rates in nature can be inferred both by progeny testing and population surveys. We then review what is currently known on the distribution of genetic diversity...
The speciose Crustacea is the largest subphylum of arthropods on the planet after the Insecta. To date, however, the only publically available sequenced crustacean genome is that of the water flea, Daphnia pulex, a member of the Branchiopoda. While Daphnia is a well-established ecotoxicological model, previous study showed that one-third of genes contained in its genome are lineage-specific and...
Using nitrogen-fixing Sinorhizobium species that interact with Medicago plants as a model system, we aimed at clarifying how sex has shaped the diversity of bacteria associated with the genus Medicago on the interspecific and intraspecific scales. To gain insights into the diversification of these symbionts, we inferred a topology that includes the different specificity groups which interact wi...
Ensifer meliloti strain RRI128 is an aerobic, motile, Gram-negative, non-spore-forming rod. RRI128 was isolated from a nodule recovered from the roots of barrel medic (Medicago truncatula) grown in the greenhouse and inoculated with soil collected from Victoria, Australia. The strain is used in commercial inoculants in Australia. RRI128 nodulates and forms an effective symbiosis with a diverse ...
Simple sequence repeat (SSR) or microsatellite DNA markers have been shown to function well in plant and mammalian species for genetic map construction and genotype identification. The objectives of the work reported here were to search GenBank for the presence of SSR-containing sequences from the genus Medicago, to assess the presence and frequency of SSR DNA in the alfalfa (Medicago sativa (L...
We present the leaf anatomy of seven amphibious species of Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, and also, providing information on which their taxonomy can be based, especially of morphologically similar species. We evaluated Aeschynomene americana, A. ciliata, A. evenia, A. denticulata, A. fluminensis, A. rudis and A. sensitiva....
Thai/Lanna medicinal plant recipes have been used for the treatment of several diseases including liver cancer. In this study, methanolic extracts (MEs) of 23 plants were tested for antiproliferative activity on human hepatoma cell line (Hep G2) by the sulforhodamine B (SRB) assay. Nine MEs with potent antiproliferative activity (IC50 < 100 µg/mL) were obtained and further semipurified by liqui...
بزرگترین جنس از تیره فرفیون، euphorbia و یکی از 6 جنس بزرگ گیاهان گلدار با حدود 2100 گونه در جهان و متجاوز از 82 گونه در نقاط مختلف ایران است .جنس euphorbia منبعی غنی از ترکیبات ترپنوئیدی محسوب می شود و گونه ی e. denticulata lam. یکی از گونه های گزارش شده در ایران است. با هدف شناسایی ترکیبات ترپنوئیدی، گونهlam. e. denticulata از مناطق غربی ایران جمع آوری و مطالعه شد. تری ترپن ها و ترکیبات استرو...
