EARLY BUD-BREAK 1 (EBB1) can promote bud break, and this function is likely conserved in woody plants. To get a more comprehensive understand of its function, peach (Prunus persica var. nectarina cultivar Zhongyou 4) PpEBB1 was overexpressed in Arabidopsis; the resultant phenotypes, including curved leaves, abnormal development of floral organs and low seed set, were similar to those of DORNRÖSCHEN-LIKE (DRNL) overexpression, indicating that PpEBB1 was a putative ortholog of AtDRNL. PpEBB1 bound to the GCC box-like element in the STYLISH1/SHI RELATED SEQUENCE5 (STY1/SRS5) promoter of peach, which has been proposed to occur in Arabidopsis as well. A GCC box-like element was also found in the YUCCA1 (YUC1) promoter, and PpEBB1 could bind to this element and activate the expression of YUC1. In addition to the elevated auxin content in the PpEBB1-oe plants as observed in our previous study, these results suggest that PpEBB1 can regulate auxin biosynthesis by directly activating related genes. Besides, we screened a zinc finger RING-finger protein, MYB30-INTERACTING E3 LIGASE 1 (PpMIEL1), showing interaction with PpEBB1, suggesting that the stability of PpEBB1 might be influenced by PpMIEL1 through ubiquitination.

Plants recognize molecular patterns unique to a certain group of microbes to induce effective resistance mechanisms. Elicitins are secretory proteins produced by plant pathogenic oomycete genera including and Treatment of INF1 (an elicitin produced by ) induces a series of defense responses in species, including reactive oxygen species (ROS) production, transient induction of ethylene production, hypersensitive cell death and accumulation of the sesquiterpenoid phytoalexin capsidiol. In this study, we analyzed the expression profiles of genes after INF1 treatment by RNAseq analysis.

MYB transcription factors play essential roles in regulating plant secondary metabolism and jasmonate (JA) signaling. Putrescine N-methyltransferase is a key JA-regulated step in the biosynthesis of nicotine, an alkaloidal compound highly accumulated in Nicotiana spp. Here we report the identification of NtMYB305a in tobacco (Nicotiana tabacum) as a regulatory component of nicotine biosynthesis and demonstrate that it binds to the JA-responsive GAG region, which comprises a G-box, an AT-rich motif, and a GCC-box-like element, in the NtPMT1a promoter.

Reactive oxygen species (ROS) act as important secondary messengers in abscisic acid (ABA) signaling and induce stomatal closure under dehydration stress. The breast cancer susceptibility gene 1 (BRCA1), an important tumor suppressor in animals, functions primarily in the maintenance of genome integrity in animals and plants. However, whether and how the plant BRCA1 regulates intracellular ROS homeostasis in guard cells under dehydration stress remains unknown.

Steroidal glycoalkaloids (SGAs) are cholesterol-derived specialized metabolites produced in species of the Solanaceae. Here, we report that a group of jasmonate-responsive transcription factors of the ETHYLENE RESPONSE FACTOR (ERF) family (JREs) are close homologs of alkaloid regulators in Cathranthus roseus and tobacco, and regulate production of SGAs in tomato. In transgenic tomato, overexpression and dominant suppression of JRE genes caused drastic changes in SGA accumulation and in the expression of genes for metabolic enzymes involved in the multistep pathway leading to SGA biosynthesis, including the upstream mevalonate pathway.
