Transcriptome landscape of a bacterial pathogen under plant immunity (PNAS)
Plant Science Research WeeklyMany studies have examined how plants respond transcriptionally to pathogen attack. This study investigates how a bacterial pathogen [Pseudomonas syringae pv. tomato DC3000 (Pto)] alters its transcriptome very early in the infection process. To accomplish this, Nobori et al. developed two methods to…
The impacts of phosphorus deficiency on the photosynthetic electron transport chain (Plant Physiol)
Plant Science Research WeeklyPhosphorus deficiency is widespread and can severely limit plant growth. Carstensen et al. investigated how P deficiency affects photosynthesis in barley. They compared chlorophyll a fluorescence transients (OJIP transients) between P-deficient, sufficient and resupplied plants. They observed depletion…
Iron availability sensed in leaf vasculature causes changes in transcriptional programs (Plant Cell Environ)
Plant Science Research WeeklyIron is an essential micronutrient for plants but it is often not bioavailable in the soil. Thus, plants have evolved difference processes for iron sensing and iron uptake. OLIGOPEPTIDE TRANSPORTER 3 (OPT3) is an important iron transporter and is a component of the systemic network that mediates iron…

WWR Full PostCommentary. 10KP: A phylodiverse genome sequencing plan
Nobody doubts the great insights we have gained about plant diversity and evolution from genome sequencing, but the patchy nature of available genomes within the plant phylogeny remains a problem. Cheng et al. describe the 10KP (10,000 Plants)…
Taproot S2E1: Phenotyping Roots without Pulling up Your Own with Guillaume Lobet
Blog, The Taproot Season 2, The-Taproot0 Comments
/
To kick off Season 2, Ivan and Liz talk with Guillaume Lobet, Assistant Professor at the Forschungszentrum Jülich and the Université Catholique de Louvain. He was also a graduate student at UCL and took three postdoctoral positions in Germany and Belgium before returning and starting his faculty position…

AUXIN RESPONSE FACTOR3 regulates floral meristem determinacy by repressing cytokinin biosynthesis and signaling ($) (Plant Cell)
Plant Science Research WeeklyThe cross-talk between cytokinin and auxin has been well established from different developmental perspective. In this article, Zhang et al. have explored the role of cytokinin and auxin cross-talk in floral meristem (FM) determinacy. The authors demonstrated that auxin induces the expression of ARF3…
Photoperiodic control of seasonal growth is mediated by ABA acting on cell-cell communication ($) (Science)
Plant Science Research WeeklyPlant growth is regulated seasonally, but our knowledge is limited about how their growth is inhibited or re-initiated seasonally. Looking at hybrid aspen, in this article, Tylewicz et al. explored how seasonal cycles of growth and dormancy help perennial plants adapt during winter. In the long days…
