Lepidium oblongum, of American origin is a new member the European adventive flora, only detected in Romania so far. The first Hungarian stand was discovered 2018, and others 2020. Based on our studies, we detail its morphological characteristics comparison with other species. We present drawing table to help identify oblongum easily identifiable by divided (lobed or lobed-dentated) upper stem ...

We report the potential phylogenetic utility of DNA sequence data from the last 700 bp of a ca. 1-kb intron of the MADS-box gene pistillata from a sampling of Sphaerocardamum species and other Brassicaceae. These results are compared with nrDNA ITS and the chloroplast trnL intron for the same taxa to demonstrate the potential phylogenetic utility of this pistillata intron and to identify potent...

The population structure of the pseudo-metallophyte herb, Arabidopsis halleri, was studied using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) on chloroplast DNA (cpDNA). The history of metallicolous (M) populations showing increased zinc tolerance was investigated. Eight primer-enzyme combinations out of 72 tested were applied to a total of 625 individuals from ...

Arabidopsis, a small annual plant belonging to the mustard family, is the subject of study for an estimated 7,000 researchers around the world. At the end of the year 2000, Arabidopsis will be the first higher plant genome completely sequenced by an international public effort, the Arabidopsis Genome Initiative (AGI; AGI et al., 2000). Similar collaborative efforts are under way to undertake a ...

Pods play a key role in encapsulating the developing seeds and protecting them from pests and pathogens. In addition to this protective function, it has been shown that the photosynthetically active pod wall contributes assimilates and nutrients to fuel seed growth. Recent work has revealed that signals originating from the pod may also act to coordinate grain filling and regulate the reallocat...
