Phytochrome Signaling: Time to Tighten up the Loose Ends

Tying up syntactic loose ends

Loose Ends

Most research projects produce generalizations to be pursued, conjectures to be proved, and special cases to be pondered–often meant to be dealt with at a later date. In this talk, I’ll give examples of such postponements from my own work that I hope will be interesting. Notation is pretty standard, I think. An [n; k]q code is a linear code of length n and dimension k over the …nite …eld Fq of ...

Loose ends

T wo is the fundamental number for genetics; all of us are the products of single zygotic events but the zygote is formed from two gametes, and two different sets of chromosomes make up our genomes. When I first learnt genetics, it was about diploids, and meiosis and the generation of haploid gametes was central to its understanding. Incidentally, lacking a classical education, I thought haplo ...

Tying up loose ends: ribosome recycling in eukaryotes and archaea.

Ribosome recycling is the final - or first - step of the cyclic process of mRNA translation. In eukaryotes and archaea, dissociation of the two ribosomal subunits proceeds in a fundamentally different way than in bacteria. It requires the ABC-type ATPase ABCE1 [previously named RNase L inhibitor (Rli)1 or host protein (HP)68], but the reaction and its regulation remain enigmatic. Here, we focus...

Tying up Loose Ends in Chondrule Formation by Shocks

Chondrule formation is a long-standing problem in meteoritics. Furnace experiments designed to reproduce chondrule textures constrain their cooling rates between their liquidus and solidus temperatures to be in the range 10-1000 K/hr [1]. This constraint, and nearly all other known constraints on chondrule formation, are satisfied if chondrules were melted by passage through solar nebula shocks...
