Tweets from the first two lectures at the International Botanical conference. Follow it at http://www.facebook.com/ibc2011 or on the web at http://ibc2011.com/

It looks like a lot of tweets for Thursday, so there’ll be a few posts today. Tim Entwisle has another IBC post up this morning about tweeting, talking about its value as conferences.
Talking Plants: International Botanical Congress in Melbourne all a twitter

Half way through the International Botanical Congress in Melbourne it’s time to draw breath. The pace has been cracking, particularly with hands on Twitter, eyes on the speaker and mind on running the Congress. Some background first. The International Botanical Congress is held every six years and attracts botanists from around the world to discuss the latest developments in plant science.

..and now this morning’s Plenary lectures. First is Prof. Peter Quail who is talking about Phytochrome photosensory signaling and transcriptional networks to a slightly depleted audience. For one reason or another.

Plenary ranks thin post-gala: suspect there may be a few botanical heads in buckets around town this AM. #ibc18

Wondered why there were so many grans on my tram to #ibc18 this morning. "Craft & Quilt Expo" next door 🙂

Hope someone who knows what phytochrome is gets here to tweet soon… #ibc18

Peter Quail – hero of phytochrome. But, @IBC11, its hard for him to tweet while talking. #ibc18

I’m here, but my knowledge of phytochrome is a few decades old. Looking forward to catching up! #ibc18

Quail: red light enhancing phosphorylation of PIF phyt int fctr serine residues: is it necessary for ubiquitylation –> degradation? #ibc18

Liking Peter Quail already, he started at the beginning. And that accent… #ibc18

Quail: yin-yang model of PIFs giving etiolation (skotomorphogenesis), phytochromes for photomorphogensis. #ibc18
Pathh1
July 27, 2011
Or even yin-yang 🙂 RT @TimEntwisle: Quail: Skotomorphogenesis-photomorphogenesis like yin-gang [but not as catchy…] #ibc18

skotomorphogenesis – now there’s a word you don’t hear every day. #ibc18

Quail: PIFs also involved in cellular signalling hub, allowing plant to respond effectively to changes in its environment. #ibc18
IBC11
July 27, 2011
Quail: PIFs function as cellular signalling hub. (TIPs review – http://bit.ly/ogXbwP ) Me: complexity of networks with interactions! #ibc18
Pathh1
July 27, 2011
But can we reduce network complexity and then model? We would like to test http://bit.ly/olHzod. with big plant networks #ibc18

Then came the next plenary lecture.
Next up: Jonathan Wendel on evolution of polyploidy in cotton #ibc18

Jonathan Wendel: Charles Darwin remains relevant 200 years after birth. His questions still important & we have new technologies. #ibc18

Wendel:"Cotton’s history interlinked with slavery & white man invasion of new world" Quotes "Cotton, 1 of Egypt’s greatest treasures" #ibc18

Wendel: Australia 7th-largest cotton producing country in world. #ibc18

#ibc18. Wendel: so happy not to have to explain ‘anthesis’ and ‘trichome’ to the audience. #roomfullofbotanygeeks

Wendel: polyploidy "ubiquitous, episodic, recurring". Ref. to Jiao et al.: http://j.mp/oOzzlv #ibc18
IBC11
July 27, 2011
Wendel: And polyploidy is a relative concept – i.e. all/most angiosperms have it to varying degrees. Gossypium, e.g., is 48-ploid. #ibc18 .
TimEntwisle
July 27, 2011
Wendel: tough life leaving Iowa in the winter to look for wild cotton in Hawaii. #ibc18
IBC11
July 27, 2011
Wendel makes great case of why knowing the whole genus of cotton then comparative analysis is so valuable for science, breeding. #ibc18
Pathh1
July 27, 2011
Wendel: oulining the evolution of cotton species an ploidy events, an elegant well-documented historical geophylo reconstruction. #ibc18

Wendel at #ibc18: 3-5% of ESTs in genome-wide scan of cotton have experienced gene conversion of small tracts, not just for ribosomal loci
EveEmshwiller
July 27, 2011
Wendel: genomic dominance in polyploids: shown in a few so far, but likely to be in most polyploids. #ibc18

Wendel: "three botany degrees… but I wouldn’t have known a profilin if it hit me in the head". #ibc18
IBC11
July 27, 2011
Wendel Summary: "here’s what I think I said!" So many non-Mendelian events to think about! #ibc18

That closes the plenary tweets. I’ll pick up the morning session i the next post.
