Salt, Jo Ann BanksPlant Cell Jun 2010, 22 (6) 2045-2057; DOI: https://doi.org/10.1105/tpc.109.069773
Gametophytes of the fern Pteris vittata can accumulate and tolerate more than 1% of their dry weight as arsenic. The authors provide evidence that the ACR3 arsenic transporter protein plays an important role in tolerance to high levels of arsenic by transporting arsenic into the vacuole.

Floral scent and color play major roles in the plant's life cycle. Using petunia as a model system, a MYB-like factor was identified that transcriptionally regulates floral scent but not pigmentation. The multilayered regulation allows efficient control of metabolic flux in the phenylpropanoid pathway.

- You have accessRestricted AccessGravitropism of Arabidopsis thaliana Roots Requires the Polarization of PIN2 toward the Root Tip in Meristematic Cortical CellsAbidur Rahman, Maho Takahashi, Kyohei Shibasaki, Shuang Wu, Takehito Inaba, Seiji Tsurumi, Tobias I. BaskinPlant Cell Jun 2010, 22 (6) 1762-1776; DOI: https://doi.org/10.1105/tpc.110.075317
Gravitropism of roots depends on a flow of auxin from the root cap to the zone of elongation via the auxin efflux carrier PIN2. While PIN2 in epidermis and lateral root cap is positioned appropriately, PIN2 in the cortex has the opposite polarity. We report that, despite this, PIN2 functions in the root cortex for optimal gravitropism, apparently by limiting the auxin flow.

Plant development depends on the balance of stem cell renewal and differentiation in several stem cell niches that is achieved by yet unknown regulatory mechanisms. Using inducible RNA interference-mediated downregulation, Arabidopsis RETINOBLASTOMA-RELATED protein is shown to regulate the proliferation, maintenance, and differentiation of stem cells and organ production from stem cell niches.

- Open AccessThe Conserved Splicing Factor SUA Controls Alternative Splicing of the Developmental Regulator ABI3 in ArabidopsisMatteo Sugliani, Vittoria Brambilla, Emile J.M. Clerkx, Maarten Koornneef, Wim J.J. SoppePlant Cell Jun 2010, 22 (6) 1936-1946; DOI: https://doi.org/10.1105/tpc.110.074674
The Arabidopsisgene ABI3 shows developmentally regulated alternative splicing. ABI3-α and ABI3-β splice variants encode full-length and truncated ABI3 proteins, respectively. The conserved splicing factor SUA reduces splicing of a cryptic ABI3 intron, which leads to the accumulation of ABI3-α. Mutations in sua suppress the frameshift mutant abi3-5 by restoring its reading frame.

In yeast and vertebrates, the essential telomere binding protein POT1 protects chromosome ends, but in Arabidopsis, POT1 proteins have evolved to bind telomerase instead. This study examines the function of POT1 in the moss Physcomitrella patens. The findings show that moss POT1 functions in a manner similar to yeast and vertebrate POT1. Thus, POT1 proteins are evolving very rapidly in plants.

BaskinPlant Cell Jun 2010, 22 (6) 1762-1776; DOI: https://doi.org/10.1105/tpc.110.075317
Gravitropism of roots depends on a flow of auxin from the root cap to the zone of elongation via the auxin efflux carrier PIN2. While PIN2 in epidermis and lateral root cap is positioned appropriately, PIN2 in the cortex has the opposite polarity. We report that, despite this, PIN2 functions in the root cortex for optimal gravitropism, apparently by limiting the auxin flow.

While PIN2 in epidermis and lateral root cap is positioned appropriately, PIN2 in the cortex has the opposite polarity. We report that, despite this, PIN2 functions in the root cortex for optimal gravitropism, apparently by limiting the auxin flow.

BaskinPlant Cell Jun 2010, 22 (6) 1762-1776; DOI: https://doi.org/10.1105/tpc.110.075317
Gravitropism of roots depends on a flow of auxin from the root cap to the zone of elongation via the auxin efflux carrier PIN2. While PIN2 in epidermis and lateral root cap is positioned appropriately, PIN2 in the cortex has the opposite polarity. We report that, despite this, PIN2 functions in the root cortex for optimal gravitropism, apparently by limiting the auxin flow.

- Open AccessArabidopsis Small Ubiquitin-Like Modifier Paralogs Have Distinct Functions in Development and DefenseHarrold A. van den Burg, Ramachandra K. Kini, Robert C. Schuurink, Frank L.W. TakkenPlant Cell Jun 2010, 22 (6) 1998-2016; DOI: https://doi.org/10.1105/tpc.109.070961
This report describes the effect that protein modifications by isoforms of the small ubiquitin-like modifier (SUMO) have on plant development and innate immunity. SUM1 and SUM2 were found to be essential for suppressing defense responses in noninfected plants by preventing accumulation of the defense hormone salicylic acid, whereas SUM3 enhances these defense responses in infected plants.

This study describes a newly isolated altered auxin response mutant. It finds that the mutant exhibits a reduction in polar auxin transport caused by a decrease in the levels of members of the PIN family of auxin efflux proteins.

This article reports that DWA1 and DWA2 may be the substrate receptors for a CULLIN E3 ligase and that they interact with themselves and each other. Heterodimeric cooperation between DWAs is a previously unknown regulatory mechanism for the action of CULLIN E3 ligases.

Class XI myosins are unique to plants and known to function in cytoplasmic streaming. This study demonstrates that the two myosin XI genes present in the moss Physcomitrella patens are functionally redundant, localize to the apical region of actively growing protonemal cells, and play a key role in tip growth.

Inherited transpositions of the endogenous Ds create stable insertion lines, a resource for targeting gene knockouts and examining mechanisms of transposition. Ds preferentially inserts into genes, at target sites within 16-bpair segments of DNA with specific structural properties. These results suggest approaches to predict insertion sites in transposon mutagenesis experiments.

Floral scent and color play major roles in the plant's life cycle. Using petunia as a model system, a MYB-like factor was identified that transcriptionally regulates floral scent but not pigmentation. The multilayered regulation allows efficient control of metabolic flux in the phenylpropanoid pathway.
