- Open AccessHUA ENHANCER1 Is Involved in Posttranscriptional Regulation of Positive and Negative Regulators in Arabidopsis PhotomorphogenesisHuang-Lung Tsai, Yi-Hang Li, Wen-Ping Hsieh, Meng-Chun Lin, Ji Hoon Ahn, Shu-Hsing WuPlant Cell Jul 2014, 26 (7) 2858-2872; DOI: https://doi.org/10.1105/tpc.114.126722
This work reports that the expression of HEN1, a small regulatory RNA methyltransferase essential for microRNA biogenesis, is activated by light signaling pathways to regulate Arabidopsis photomorphogenesis. The expression of positive (HY5) and negative (TCPs) regulators is tuned by miR157d and miR319, respectively, in deetiolating seedlings, demonstrating a posttranscriptional control in the photomorphogenic development.

Contribution of cyclic electron flow to photosynthesis and biomass productivity is explored in a Chlamydomonas reinhardtii PGRL1-deficient mutant. Induction of different mechanisms, including cooperation between photosynthesis and mitochondrial respiration and oxygen photoreduction (direct or flavodiiron-mediated), efficiently compensates for the deficit in ATP supply under steady state, but not under transient or fluctuating conditions.

Arabidopsis seeds with a mutation in urate oxidase show a defect in germination, fail to develop the cotyledons, and exhibit partially blocked β-oxidation. These phenotypes result from the accumulation of uric acid and are suppressed by the additional mutation of xanthine dehydrogenase, which prevents uric acid accumulation. The data presented show that peroxisome maintenance is compromised by uric acid.

Arabidopsis seeds with a mutation in urate oxidase show a defect in germination, fail to develop the cotyledons, and exhibit partially blocked β-oxidation. These phenotypes result from the accumulation of uric acid and are suppressed by the additional mutation of xanthine dehydrogenase, which prevents uric acid accumulation. The data presented show that peroxisome maintenance is compromised by uric acid.

This work reports the discovery of the DELLA-binding transcription factor GAF1 and shows that DELLAs and TPR act as coactivators and a corepressor with GAF1, respectively. GA converts the GAF1 complex from transcriptional activator to repressor via degradation of DELLAs. Accordingly, DELLAs turn on or off two sets of GA-regulated genes by dual functions, namely titration and coactivation.

This work presents a model of the plant intracellular trafficking system developed by analyzing the subcellular localization of GNOM ARF-GEF, which is crucial for auxin transport-mediated plant development. The data show that GNOM is associated with Golgi body, rather than endosomes as previously believed, and redefine our notions about the identity and function of recycling endosomes in plants.

This study identified multiple whole-genome duplication (WGD) events among Brassicaceae species. Remarkably, these events, as well as previously identified WGD events, are synchronized in age, coincident with epoch transitions, adding to the evidence suggesting the environmental instability associated with these transitions favors polyploidy and rapid species diversification.
