ParkerPlant Cell Jul 2011, 23 (7) 2788-2803; DOI: https://doi.org/10.1105/tpc.111.087684
This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

This study shows that the major ubiquitin receptors involved in targeting ubiquitylated proteins for proteasome-mediated proteolysis are functionally redundant in Arabidopsis. Interestingly, in addition to playing a redundant role in substrate recognition, the Arabidopsis proteasome subunit RPN10 maintains the structural integrity of proteasome, which is critical for vegetative and reproductive growth.

- Open AccessRecruitment of a Ribosomal Release Factor for Light- and Stress-Dependent Regulation of petB Transcript Stability in Arabidopsis ChloroplastsRhea Stoppel, Lina Lezhneva, Serena Schwenkert, Salar Torabi, Susanne Felder, Karin Meierhoff, Peter Westhoff, Jörg MeurerPlant Cell Jul 2011, 23 (7) 2680-2695; DOI: https://doi.org/10.1105/tpc.111.085324
The plastid ribosomal release factor-like protein PrfB3 arose from a gene duplication and has subsequently lost the two most important tripeptide motifs required for stop codon recognition and catalysis. This work shows that PrfB3 is essential in vascular plants and has been recruited for binding and environment-dependent stabilization of petB RNA to regulate cytochrome b6f complex levels.

Whereas microtubules and cellulose synthase trajectories are transversely oriented on the outer epidermal surface of Arabidopsis hypocotyl cells only for part of the growth cycle, microtubules and microfibrils at the inner surface remain transverse throughout growth. The inner face of the epidermis is thus established as a regulator of growth anisotropy in the hypocotyl.

ParkerPlant Cell Jul 2011, 23 (7) 2788-2803; DOI: https://doi.org/10.1105/tpc.111.087684
This work identified two different Arabidopsis mutants that have reduced susceptibility to an infectious biotrophic pathogen due to overaccumulation of the amino acid Thr. This is detrimental for the host plant and the infecting pathogen but does not affect disease caused by some other pathogen species. Therefore, the host metabolic state can influence disease in quite a specific manner.

In plants grown under field conditions, seed dormancy varies considerably with the time of year the seed is set, and this variation is important for the coordination of plant life history and seed quality. This work elucidates the mechanisms through which environmental temperature during seed set affects the germination behavior of seeds when released from the mother plant.

We constructed a CRE/lox clonal deletion system named BOB (Brother of Brainbow), which allows tissue-specific elimination of gametophytic essential genes from desired cells. The null sectors, marked by a combination of fluorescent proteins, show that genomic removal of RBR leads to cell-autonomous overproliferation of the quiescent center and distal columella stem cells.

Whereas microtubules and cellulose synthase trajectories are transversely oriented on the outer epidermal surface of Arabidopsis hypocotyl cells only for part of the growth cycle, microtubules and microfibrils at the inner surface remain transverse throughout growth. The inner face of the epidermis is thus established as a regulator of growth anisotropy in the hypocotyl.

Fernie, Harry J. KleePlant Cell Jul 2011, 23 (7) 2738-2753; DOI: https://doi.org/10.1105/tpc.111.086975
Ectopic expression of a MYB transcription factor, ODO1, in tomato fruit altered Phe and phenylpropanoid metabolism, as shown by metabolic profiling and flux analysis. This disruption permitted identification of a set of coregulated genes, including prephenate aminotransferase, which converts prephenate to arogenate. The results establish a fruit arogenate pathway for Phe synthesis.

The plastid ribosomal release factor-like protein PrfB3 arose from a gene duplication and has subsequently lost the two most important tripeptide motifs required for stop codon recognition and catalysis. This work shows that PrfB3 is essential in vascular plants and has been recruited for binding and environment-dependent stabilization of petB RNA to regulate cytochrome b6f complex levels.

We constructed a CRE/lox clonal deletion system named BOB (Brother of Brainbow), which allows tissue-specific elimination of gametophytic essential genes from desired cells. The null sectors, marked by a combination of fluorescent proteins, show that genomic removal of RBR leads to cell-autonomous overproliferation of the quiescent center and distal columella stem cells.
