Testing Zimmermann’s Telome Theory

Posted by on August 1st, 2018

A perspective on our recent paper ‘CLAVATA was a genetic novelty for the morphological innovation of 3D growth in land plants’1.   In the 1950’s, the German botanist Walter Zimmermann (photo here) hypothesized a series of developmental transitions enabling plant forms to radiate during evolution2. Zimmermann’s so-called Telome Theory has received much attention from those[…]

Building the BSDB family network

Posted by on July 23rd, 2018

This year the British Society for Developmental Biology turned 70, and celebrated the milestone at its Spring meeting at Warwick (check out Twitter for some of the fun, and Andreas Prokop gave a great meeting report over on the BSDB page).     The great and the good of British developmental biology were in attendance,[…]

The people behind the papers – Takanori Wakatake & Ken Shirasu

Parasitic plants are fascinating and agriculturally relevant organisms that rely for their success on the haustorium, a specialised root structure that invades host root vasculature to derive nutrients and water. A recent paper in Development addresses the developmental origins of these crucial structures in the facultative root parasite Phtheirospermum japonicum. We caught up with first author Takanori Wakatake and[…]

Life changing experiences with Embryos

Posted by on July 18th, 2018

It’s hard to describe with words how my experience has been at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, but I’m going to give it a try… My attendance at the 2018 Embryology course at the MBL, has been possible thanks to an award I won in my home country, during the International[…]

Asymmetric division is a widespread mechanism for generating cellular diversity during developmental patterning. The stomata of flowering plants are epidermal valves that regulate gas exchange, and provide an accessible system to investigate the mechanisms of asymmetric cell division both within and across species. A paper in the new issue of Development reports an investigation of the molecular control of this[…]

Evo-chromo: towards an integrative approach of chromatin dynamics across eukaryotes

Posted by on July 18th, 2018

***Deadline to apply for funded ECR places is July 20!***   In November, the Company of Biologists is hosting the latest in its series of Workshops. ‘Evo-chromo’ aims to integrate skills and interests of the fields of chromatin biology and evolutionary biology – if you are an early career researcher and this all sounds appealing[…]

Differentiating cells mechanically limit progenitor cells’ interkinetic nuclear migration to secure apical cytogenesis

Posted by on July 17th, 2018

Press release for Yuto Watanabe, Takumi Kawaue and Takaki Miyata‘s new Development paper   Key Points Developing brains use a mechanism like the Otoshi-buta (the drop lid), a kitchen wisdom. Differentiating cells in embryonic cerebral walls form a dense filter-like layer to mechanically barrier nuclei of neural stem cells. Loss of this barrier or fence results in[…]

The National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) is running a workshop bringing together rodent and non-mammalian model organism users, facilitating research partnerships and encouraging the development of new and innovative applications of non-mammalian organisms.     There will be an opportunity to: Hear from rodent and non-mammalian model organism users. Learn[…]

A day in the life of a Capitella teleta lab

Posted by on July 10th, 2018

It’s undoubtedly the middle of summer here in Saint Augustine, Florida. Daily temperatures are soaring into the 90s, and we’re grateful if the humidity dips below 70%. Thankfully, the Seaver lab doesn’t have to contend with much of this heat. Instead, our members are inside, comfortable though busier than ever, mentoring summer interns, piloting new[…]

All beauty must die

Posted by on July 9th, 2018

Anna Daneva, Zhen Gao and Moritz Nowack tell the story behind their recent paper in Nature Plants   The transience of flowers is proverbial. Degeneration of flowers is elicited after successful pollination by the onset of seed and fruit development. However, also unpollinated flowers do not last forever – on the contrary, the life span[…]
