IAB blog second year

The IAB blog site is very much alive, as it starts its third year. It has become a very dynamic complement to the old IAB web site. Due to the open collaboration structure, it is easier for anyone to post content on line, in comparison to the restricted access to update the static IAB we site at www.bryology.org. I invite all those interested in any aspect of bryophytes to become active collaborators to add blog content. This is the place for sharing news, commentaries on recent papers, spark discussions, share your pictures of bryologists in action, etc.

The map above shows a summary of visitors to the blog from September 2009 to August 2010. The Table below has the average number of visitors per month.

Conservation between higher plants and the moss Physcomitrella patens in response to the phytohormone abscisic acid: a proteomics analysis

The plant hormone abscisic acid (ABA) is ubiquitous among land plants where it plays an important role in plant growth and development. In seeds, ABA induces embryogenesis and seed maturation as well as seed dormancy and germination.

In vegetative tissues, ABA is a necessary mediator in the triggering of many of the physiological and molecular adaptive responses of the plant to adverse environmental conditions, such as desiccation, salt and cold.

Results: In this study, we investigated the influence of abscisic acid (ABA) on Physcomitrella patens at the level of the proteome using two-dimensional gel electrophoresis (2-DE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Sixty-five protein spots showed changes in response to ABA treatment.

Bryophyte photo of the week: Marchantia

By BlueRidgeKitties No real name given

Marchantia Sporangia

Sexual reproduction in Marchantia - the archegonial head makes the egg cells and, after fertilization with sperm splashed over by the rain from the male part of the plant, the zygote develops into a sporophyte that stays attached underneath the head. The young sporophytes are covered by the white calyptra developing from the wall of the archegonium until the sporangium emerges from its cover. The diploid sporophyte pretty much consists only of a foot (where it is attached to the gametophyte), a short stalk (or seta), and a sporangium which produces spores through meiosis. The rest of the plant is haploid.

Join the social network group at MyPlant.org

The Moss node at MyPlant.org, the social network for the plant sciences, is now active!

This Moss social network group has just begun with the goal of bringing together all different sort of researchers who study these plants, the most interesting clade on the tree of life!

This site has many advantages over static email lists with its nested structure, focused (and archived) discussion threads, documents, picture, and movie sharing, etc. For example, this might be the perfect place where to produce an up to date list of student research projects for MSc and PhD theses. Students need to join to be able to add content as a "post" with project description, the student's name, contact details, supervisor's name and contact details, school or institution affiliation, etc. Each post intended for the list will include a shared label to automate archiving and displaying. Something like: "Theses Research Projects" will work. Everyone can see all content browsing the Moss Clade homepage. https://my-plant.org/clade...

Please join in, add material, share data and information, and help make the group grow.
