miRNA-Mediated Regulation of Germination

Guo et al. show that miR9678 affects seed germination in wheat by generating phased siRNAs and modulating abscisic acid/gibberellin signaling. Plant Cell https://doi.org/10.1105/tpc.17.00842 By Guanghui Guo and Yingyin Yao Background:  Seed germination is important for grain yield and quality and rapid, near-simultaneous germination in a crop helps in cultivation; however, cultivars that germinate too readily […]

A Brake For Nitrogen Starvation Responses

Kiba et al. focus on transcriptional regulation of nitrogen starvation responses. Plant Cell https://doi.org/10.1105/tpc.17.00810 By Takatoshi Kiba Background: Nitrogen availability in the soil profoundly affects plant growth and productivity, and thus crop yield. To meet expanding food demands, the global use of nitrogen fertilizer in agricultural production has increased dramatically since the 1950s and the […]

Gender Identity in Kiwifruit

Akagi et al. identify a gender determining gene in kiwifruit. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00787 By T. Akagi, I. M. Henry, H. Ohtani, T. Morimoto, K. Beppu, I. Kataoka, and R. Tao Background: In flowering plants, hermaphroditism, or the presence of both male and female organs in each flower, represents the most common state, and […]

A New Player In Plant Respose to Far-red Light

Zhang et al. discover a protein that interacts with the photoreceptor phyA and plays a role in plant response to far-red light. Plant Cell https://doi.org/10.1105/tpc.17.00677  By Shaoman Zhang, Cong Li and Jigang Li Background:  Far-red (FR) light, corresponding to 700- to 750- nm wavelengths of sunlight, is not used by plants for photosynthesis and thus […]

How Plants Generate Circadian Rhythms in Transcription

Ma et al. investigate a protein complex that controls steady-state mRNA circadian oscillations  https://doi.org/10.1105/tpc.18.00052  By Yuan Ma, Sergio Gil, Klaus D. Grasser and Paloma Mas Background: Circadian clocks are internal time-keeping mechanisms that help organisms to adapt to the environmental changes that occur during the day and night cycle. In Arabidopsis thaliana, the circadian clock […]

B-GATAs Fine Tune Greening

Bastakis et al. investigate control of the greening process in Arabidopsis https://doi.org/10.1105/tpc.17.00947. By Emmanouil Bastakis Background: The greening of the plants is based on the synthesis and accumulation of the chlorophylls, which takes place in chloroplasts. Chlorophylls capture the energy from sunlight and then use it to convert CO2 from the atmosphere into sugars, which […]

Protein Editing for Multi-Tasking

Zauner et al. investigate the mechanism of protein re-purposing. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00963. By Florian B. Zauner, Elfriede Dall and Hans Brandstetter Background: Plants cannot run away from herbivores, drought, or heat. To withstand adverse conditions, plants have developed a diverse arsenal of proteins, their proteomes (total complement of proteins). Certain enzymes function to […]
