MicroRNAs (miRNAs) have important roles in gene regulation during plant development. Previous studies revealed that some miRNAs are highly shared by most land plants. Recently, the liverwort, Marchantia polymorpha, has been studied by molecular genetic approaches, and sequencing of its genome is currently underway. The expression pattern and the detailed functions of miRNAs during Marchantia de...

medicago spp. is the most important forage crop in many regions of the world.annual medics have distinct advantages over perennial medicago. these species have fastergrowth rate in cultivation year, higher crude protein percentage, tolerance to pests and morevigorous seedlings. morphological and physical aspects of pod and seeds of annual medicsplay a major role in the tolerance of the plants t...

Within a single site in the Kohala Forest Reserve, Hawai`i, we examined the composition and diversity of soil microbial communities under four introduced (Cryptomeria japonica, Casuarina equisetifolia, Araucaria columnaris, and Eucalyptus sp.) and one native (Metrosideros polymorpha) canopy tree species, as well as pasture. Terminal restriction fragment length polymorphism (T-RFLP) analysis of ...

We previously reported Agrobacterium-mediated transformation methods for the liverwort Marchantia polymorpha using the hygromycin phosphotransferase gene as a marker for selection with hygromycin. In this study, we developed three additional markers for M. polymorpha transformation: the gentamicin 3'-acetyltransferase gene for selection with gentamicin; a mutated acetolactate synthase gene for ...

Marchantia polymorpha is an extant relative of the earliest terrestrial plants and has attracted a substantial interest as a model organism for evolutionary and developmental studies. Given its relatively simple genome, compact gene families, simple morphology, ease of propagation and transformation, M. polymorpha is becoming a promising platform for plant synthetic biology. Modular genetic par...

The liverwort Marchantia polymorpha is a member of the most basal lineage of land plants (embryophytes) and likely retains many ancestral morphological, physiological and molecular characteristics. Despite its phylogenetic importance and the availability of previous EST studies, M. polymorpha's lack of economic importance limits accessible genomic resources for this species. We employed Illumin...

ABSTRACT- Annual Medicago species (Medicago spp.) are native to the Mediterranean region and widely used in fields and pastures in Iran. There are several methods of sowing annual Medicago species, each with different effects on the performance. However, there is currently no sufficient information about the appropriate methods for sowing Medicago species. In order to evaluate methods of sowing...
