Journal ArticleDOI
A new view of the tree of life
Laura A. Hug,Laura A. Hug,Brett J. Baker,Karthik Anantharaman,Christopher T. Brown,Alexander J. Probst,Cindy J. Castelle,Cristina N. Butterfield,Alex W Hernsdorf,Yuki Amano,Kotaro Ise,Yohey Suzuki,Natasha Dudek,David A. Relman,David A. Relman,Kari M. Finstad,Ronald Amundson,Brian C. Thomas,Jillian F. Banfield,Jillian F. Banfield +19 more
TL;DR: New genomic data from over 1,000 uncultivated and little known organisms, together with published sequences, are used to infer a dramatically expanded version of the tree of life, with Bacteria, Archaea and Eukarya included.
Journal ArticleDOI
Brassinosteroid perception in the epidermis controls root meristem size
Yael Hacham,Neta Holland,Cristina N. Butterfield,Susana Ubeda-Tomás,Malcolm J. Bennett,Joanne Chory,Joanne Chory,Sigal Savaldi-Goldstein,Sigal Savaldi-Goldstein +8 more
TL;DR: It is shown that BRs are required to maintain normal cell cycle activity and cell expansion, and that BR signaling in the root epidermis and not in the inner endodermis, quiescent center (QC) cells or stele cell files is sufficient to control root meristem size.
Journal ArticleDOI
Novel soil bacteria possess diverse genes for secondary metabolite biosynthesis
Alexander Crits-Christoph,Spencer Diamond,Cristina N. Butterfield,Brian C. Thomas,Jillian F. Banfield +4 more
TL;DR: It is concluded that the biosynthetic potential of abundant and phylogenetically diverse soil microorganisms has previously been underestimated and may represent a source of natural products that can address needs for new antibiotics and other pharmaceutical compounds.
Journal ArticleDOI
Mn(II,III) oxidation and MnO2 mineralization by an expressed bacterial multicopper oxidase
TL;DR: The results demonstrate that Mn oxidation from soluble Mn(II) to Mn(IV) oxides is a two-step reaction catalyzed by an MCO-containing complex, broadening the understanding of Mn mineral formation and the bioinorganic capabilities of MCOs.
Journal ArticleDOI
New auxin analogs with growth-promoting effects in intact plants reveal a chemical strategy to improve hormone delivery
Sigal Savaldi-Goldstein,Thomas J. Baiga,Florence Pojer,Tsegeye Dabi,Cristina N. Butterfield,Geraint Parry,Aaron Santner,Nihal Dharmasiri,Yi Tao,Mark Estelle,Joseph P. Noel,Joanne Chory +11 more
TL;DR: These studies exemplify the combined power of chemical genetics and biochemical analyses for discovering and refining prohormone analogs with selective activity in specific plant tissues, and can envision using these simple principles to study other plant hormone and small molecule responses in temporally and spatially controlled ways.
