Abstract:
... Plants of the legume family host massive intracellular bacterial populations in the tissues of specialized organs, the nodules. In these organs, the bacteria, named rhizobia, can fix atmospheric nitrogen and transfer it to the plant. This special metabolic skill provides to the legumes an advantage when they grow on nitrogen-scarce substrates. While packed with rhizobia, the nodule cells remain al ...

Abstract:
... The isolation of root nodule bacteria (RNB) usually lead to obtainment of several non-rhizobia, mainly those fast-growing bacteria. The plant-authentication experiments to select the nodulating bacteria are time consuming and can be ruined in case of nodulation of negative controls. To speed up this step in rhizobiology research a fast, simple and efficient duplex PCR assay for the amplification o ...

Abstract:
... Cycloidea-like (CYC-like) genes are the key regulatory factors in the development of flower symmetry. Duplication and/or reduction of CYC-like genes have occurred several times in various angiosperm groups and are hypothesized to be correlated with the evolution of flower symmetry, which in turn has contributed to the evolutionary success of these groups. However, less is known about the evolution ...

Abstract:
... Legume cultivation has been declining for several decades in France and in Europe as a whole. This is the result of the agri-food system lock-in around major crops, which has led to a strong simplification of cropping systems and a specialization of territories, in which legumes have been marginalized. Introducing or increasing legume production on farms has become a key issue in many European cou ...

Abstract:
... Detarioideae is well known for its high diversity of floral traits, including flower symmetry, number of organs, and petal size and morphology. This diversity has been characterized and studied at higher taxonomic levels, but limited analyses have been performed among closely related genera with contrasting floral traits due to the lack of fully resolved phylogenetic relationships. Here, we used f ...

Abstract:
... Microbial symbionts exhibit broad genotypic variation in their fitness effects on hosts, leaving hosts vulnerable to costly partnerships. Interspecific conflict and partner‐maladaptation are frameworks to explain this variation, with different implications for mutualism stability. We investigated the mutualist service of nitrogen fixation in a metapopulation of root‐nodule forming Bradyrhizobium s ...

The digestion rate for starch in legumes is lower than that in cereals. Inclusion of legumes in normal diets provides several health benefits for various metabolic syndromes. Legumes are normally consumed after processing ...

Abstract:
... The abscission zone (AZ) is a specialized tissue that usually develops at the base of an organ and is highly sensitive to phytohormones, e.g., abscisic acid (ABA), ethylene (ET), and gibberellins (GAs). A current model of organ abscission assumes that the formation of an auxin gradient around the AZ area determines the time of shedding; however, that thesis is supported by studies that are primari ...

Abstract:
... Sodium dodecyl sulfate (SDS) is a detergent used as a strong denaturant of proteins in gel electrophoresis. It has previously been shown that certain hyperstable, also known as kinetically stable, proteins are resistant to SDS and thus require heating for their denaturation in the presence of SDS. Because of its high denaturing strength, relatively few proteins are resistant to SDS thereby limitin ...

In this paper we report a plant megafossil assemblage from the Kailas Formation of the ...
