The Elegant Simplicity of the Liverwort Marchantia polymorpha.
Plants have evolved several ways to remain dormant until the time is right for growth. For example, seeds maintain dormancy through the antagonistic effects of the phytohormones abscisic acid (ABA) and gibberellic acid. Auxin (indole-3-acetic acid [IAA]), in turn, regulates ABA-induced seed dormancy through its interaction with the ABA signaling pathway (Liu et al., 2013). Dormancy is also cruc...
متن کاملMolecular evolution of mitochondrial introns in the liverwort Marchantia polymorpha
We here describe in detail the characterization and molecular evolution of group II introns in the mitochondrial genome of the liverwort Marchantia polymorpha. We find that 18 introns of the 25 group II introns can be assigned by their similarities to six clusters, indicating an intra-genomic propagation of one ancestral intron each into the respective clusters in the liverwort mitochondrial ge...

رشد انفجاری تکنولوژی فرصت های آموزشی مهیج و جدیدی را پیش روی فراگیران و آموزش دهندگان گذاشته است. امروزه معلمان برای اینکه در امر آموزش زبان بروز باشند باید روش هایی را اتخاذ نمایند که درآن ها از تکنولوژی جهت کمک در یادگیری زبان دوم و چندم استفاده شده باشد. با در نظر گرفتن تحولاتی که رشته ی آموزش زبان در حال رخ دادن است هم اکنون زمان مناسبی برای ارزشیابی نگرش های موجود نسبت به تکنولوژی های جدید...
15 صفحه اولCryopreservation of Gemmae from the Liverwort Marchantia polymorpha L.
The liverwort Marchantia polymorpha L. is one of the key model plants in evo-devo studies, and an increasing number of transgenic and mutant lines have been established. For reliable long-term preservation of M. polymorpha plants, spores have been used, but crossing is indispensable to obtain them. Gemmae, however, are vegetative clones and readily available in large numbers without crossing, t...
متن کاملSexual Organs of Marchantia polymorpha
A total of 935 expressed sequence tags (ESTs) from male immature sexual organ were determined, of which 600 ESTs were assembled into 110 non-redundant groups, resulting in 445 unique EST sequences. Of these, 244 sequences shared significant similarities to known nucleotide or amino acid sequences in other organisms. The remaining 201 unique sequences showed no significant matches and thus are l...
