New taxonomic monograph of water buttercups (Ranunculus sect. Batrachium)

After 50 years since the first monograph of the group was published,  a new taxonomic account of water buttercups (Ranunculus sect. Batrachium) was realized. International research team with Joanna Zalewska-Gałosz from our Institute published a completed taxonomic characterizations of 30 species of Batrachium occurring worldwide. Diagnostic characters, identification keys, ecological preferences and geographical ranges for all 30 taxa were also presented. We hope that this work will be a starting point for more advanced, scientific studies of this interesting group of aquatic plants.

Symbiotic fungi may accelerate plant invasions

Two invasive plants, Rudbeckia laciniata and Solidago gigantea (Asteraceae), are strongly dependent on arbuscular mycorrhizal fungi (AMF) for their growth. The fungi also increased P concentration in shoots. However, the magnitude of the response of both plant species to AMF was dependent on the fungal and soil identities. The findings of Marta Majewska, Kaja Rola and Szymon Zubek thus indicate that the presence of particular AMF species in a site enhances the performance of plants and may determine the success of their invasion.

New research project in our institute

Dr Małgorzata Jaźwa has received a grant for a project “The floristic diversity and physicochemical properties of soils on the roadsides", from the Polish National Science Foundation. Congratulations!

Immunolocalization of cyclotides in plant cells, tissues and organ supports their role in host defense

The distribution of cyclotides was visualized using immunohistochemistry in cells of leaf, petiole and root fragments of Viola odorata and Viola uliginosa of the Violaceae family rich in species producing  cyclotides, head-to-tail cyclic plant peptides consisting of approximately 30 amino acids, having diverse biological activities. Relatively large quantities were observed in tissues potentially vulnerable to pathogen attacks (the leaf and petiole epidermis and in vascular tissue in all the assessed plant organs). The findings of international group, with Elżbieta Kuta from our Institute, supports cyclotides role as defense molecules.
