Project description:Leaf senescence is the final developmental process that includes the mobilization of nutrients from old leaves to newly growing tissues. The progression of leaf senescence requires dynamic but coordinated changes of gene expression. Although several transcription factors (TFs) are known to be involved in both negative and positive modes of regulation of leaf senescence, detailed mechanisms that underlie the progression of leaf senescence are largely unknown. We report here that the class II ERF transcriptional repressors are controlled by proteasome and regulate the progression of leaf senescence in Arabidopsis. Since we had previously demonstrated that NtERF3, a model of tobacco class II ERFs, specifically interacts with a ubiquitin-conjugating enzyme, we examined the stability of NtERF3 and found that bacterially produced NtERF3 was rapidly degraded by plant protein extracts in vitro. Whereas NtERF3 accumulation was low in plants, it was increased by treatment with a proteasome inhibitor. Arabidopsis class II ERFs, namely, AtERF4 and AtERF8, were also controlled by proteasome and stabilized by aging of plants. The transgenic plants in which NtERF3, AtERF4, and AtERF8 were individually expressed under the control of the 35S promoter exhibited the precocious leaf senescence. Our microarray and RT-PCR analyses revealed that AtERF4 regulated expression of genes involving in various stress responses and leaf senescence. In contrast, aterf4 aterf8 mutant exhibited delayed leaf senescence. Taken together, we present the important role of class II ERFs in the regulation of leaf senescence. Transcriptomes of 35S:AtERF4-HA and 35S:NLS-GFP-HA (control) Arabidopsis two-weeks seedling were compared.

Project description:Antirrhinum R2R3 MYB transcription factor MIXTA is known to regulate epidermal cell outgrowth in petal. Arabidopsis has three MIXTA-like proteins NOECK(NOK)/MYB106, MYB16 and MYB17 and nok mutant exhibits over-branched trichomes in rosette leaves. On the other hand, Arabidopsis AP2/ERF transcription factor WAX INDUCER1/SHINE1 is well known to induce cuticle development. Here, we report the transcriptional cascade of MYBs-WIN/SHNs coordinately regulates the epidermal cuticle development. The constitutive expression of MYB106 chimeric repressor, in which strong repression domain was fused with MYB106 (35S:MYB106SRDX), induced cuticle deficiency characterized by organ adhesion, reduction of epicuticular wax crystals and staining by toluidine blue in broad region of aerial parts in addition to the over-branched trichomes. Most these phenotypes were partially reproduced in T-DNA knockout plants and also similarly induced by the chimeric repressors of WIN1/SHINE1(SHN1), SHN2 and SHN3, which are AP2/ERF transcription factors previously shown as positive regulators of cutin. Microarray experiments revealed that MYB106SRDX and WIN1SRDX plants have similar transcriptomes, in which the expression of wax and cutin biosynthetic genes was suppressed. Conversely, VP16-fused MYB106 which has high activation ability induced ectopic production of cutin nanoridges in the transgenic plants and enhanced the reporter driven by promoters of WIN1 and wax-related genes in transient expression assay. These results suggest that MIXTA-like proteins regulate cutin biosynthesis partially via WIN1 and directly regulate wax accumulation as well as their known roles in epidermal cell differentiation. Transcriptomes of 35S:WIN1and vector-control Arabidopsis seedling were compared.
