The 25 conservation of genetic functions conferring carpel identity has been widely studied 26 in higher plants. However, although genetic networks directing the development of 27 characteristic features of angiosperm carpels such as stigma and style are 28 increasingly known in Arabidopsis thaliana, little information is available on the 29 conservation and diversification of these networks in other species. -
Other Roles of Euap2 Genes in Plant Development Charles U
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 24 October 2019 doi:10.20944/preprints201901.0035.v3 Review Besides and Beyond Flowering: Other roles of euAP2 genes in plant development Charles U. Solomon1, 2* and Sinead Drea1 1Department of Genetics and Genome Biology, University of Leicester, UK; [email protected]; [email protected] 2Department of Plant Science and Biotechnology, Abia State University, Uturu, Nigeria *Correspondence: [email protected] Abstract: EuAP2 genes are famous for their role in flower development. A legacy of the founding member of this subfamily of transcription factors, whose mutants lacked petals in Arabidopsis. However, studies of euAP2 genes in several species have accumulated evidence highlighting the diverse roles of euAP2 genes in other aspects of plant development. Here, we emphasize other developmental roles of euAP2 genes in various species and suggest a shift from regarding euAP2 genes as just flowering genes to consider the global role they may be playing in plant development. We hypothesize that their almost universal expression profile and pleiotropic effects of their mutation suggest their involvement in fundamental plant development processes. Keywords: EuAP2 genes; Flowering; Plant Development Introduction APETALA 2 (AP2) genes are named after a series of Arabidopsis mutants characterized by homeotic transformations of their sepals to leaves and petals to staminoid petals. Analysis of the ap2 mutants along with other floral mutants gave birth to the ABC model of flower development where AP2 is classified as an A-class gene [1, 2]. The forerunner AP2 protein was cloned and characterized in Arabidopsis [3]. The Arabidopsis AP2 protein comprising 432 amino acids (aa) is mainly characterized by the possession of two AP2 domains, each made up of 68-aa with an 18-aa core conserved section that forms an amphipathic -훼–helix . -
Hypothetical Cytokinin-Binding Riboswitches in Arabidopsis Thaliana Jeremy Grojean1, Brian Downes2*
Grojean and Downes Biology Direct 2010, 5:60 http://www.biology-direct.com/content/5/1/60 HYPOTHESIS Open Access Riboswitches as hormone receptors: hypothetical cytokinin-binding riboswitches in Arabidopsis thaliana Jeremy Grojean1, Brian Downes2* Abstract Background: Riboswitches are mRNA elements that change conformation when bound to small molecules. They are known to be key regulators of biosynthetic pathways in both prokaryotes and eukaryotes. Presentation of the Hypothesis: The hypothesis presented here is that riboswitches function as receptors in hormone perception. We propose that riboswitches initiate or integrate signaling cascades upon binding to classic signaling molecules. The molecular interactions for ligand binding and gene expression control would be the same as for biosynthetic pathways, but the context and the cadre of ligands to consider is dramatically different. The hypothesis arose from the observation that a compound used to identify adenine binding RNA sequences is chemically similar to the classic plant hormone, or growth regulator, cytokinin. A general tenet of the hypothesis is that riboswitch-binding metabolites can be used to make predictions about chemically related signaling molecules. In fact, all cell permeable signaling compounds can be considered as potential riboswitch ligands. The hypothesis is plausible, as demonstrated by a cursory review of the transcriptome and genome of the model plant Arabidopsis thaliana for transcripts that i) contain an adenine aptamer motif, and ii) are also predicted to be cytokinin- regulated. Here, one gene, CRK10 (for Cysteine-rich Receptor-like Kinase 10, At4g23180), contains an adenine aptamer-related sequence and is down-regulated by cytokinin approximately three-fold in public gene expression data. -

In grapevine (Vitis vinifera L.), it has been suggested that abnormalities in pollen development lead to the phenomenon called parthenocarpy that occurs in some varieties of this cultivar. At present, a network involving several transcription factors types has been revealed and key roles have been assigned to members of the C2H2 zinc-finger proteins (ZFP) family in model plants. However, particularities of the regulatory mechanisms controlling pollen formation in grapevine Citation: Arrey-Salas, O.; remain unknown. In order to gain insight into the participation of ZFPs in grapevine gametophyte Caris-Maldonado, J.C.; development, we performed a genome-wide identification and characterization of genes encoding Hernández-Rojas, B.; Gonzalez, E. ZFP (VviZFP family). -

Pollination-Induced Gene Changes That Lead to Senescence in Petunia × Hybrida
Pollination-Induced Gene Changes That Lead to Senescence in Petunia × hybrida DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Shaun Robert Broderick, M.S. Graduate Program in Horticulture and Crop Science The Ohio State University 2014 Dissertation Committee: Michelle L. Jones, Advisor Feng Qu Eric J. Stockinger Esther van der Knaap Copyrighted by Shaun Robert Broderick 2014 Abstract Flower longevity is a genetically programmed event that ends in flower senescence. Flowers can last from several hours to several months, based on flower type and environmental factors. For many flowers, particularly those that are ethylene- sensitive, longevity is greatly reduced after pollination. Cellular components are disassembled and nutrients are remobilized during senescence, which reduces the net energy expenditures of floral structures. The goal of this research is to identify the genes that can be targeted to extent shelf life by inhibiting pollination-induced senescence. Identifying and characterizing regulatory shelf-life genes will enable breeders to incorporate specific alleles that improve post production quality into ethylene-sensitive crops. Petunia × hybrida is particularly amenable to flower longevity studies because of its large floral organs, predictable flower senescence timing, and importance in the greenhouse industry. A general approach to gene functional analysis involves reducing gene expression and observing the resulting phenotype. Viruses, such as tobacco rattle virus (TRV), can be used to induce gene silencing in plants like petunia. We optimized several parameters that improved virus-induced gene silencing (VIGS) in petunia by increasing the consistency and efficiency of silencing. -

The conversion of the tachyzoite-containing parasitophorous vacuole membrane into the less permeable bradyzoite cyst wall, allows the parasite to persist for years within the host to maximize transmissibility to both primary (felids) and secondary (virtually all other warm-blooded vertebrates) hosts. This review presents our current understanding of the latent stage, including the factors that are important in bradyzoite induction and maintenance. Also discussed are the recent studies that have begun to unravel the mechanisms behind stage switching. Keywords Toxoplasma; toxoplasmosis; differentiation; encystation; tachyzoite; bradyzoite; latency; gene regulation; epigenetics; immunity INTRODUCTION Toxoplasma gondii is an obligate intracellular protozoan parasite capable of infecting warm- blooded vertebrates world-wide [1]. -

Overexpression (OE) lines of Arabidopsis thaliana purple acid phosphatase 2 (AtPAP2) were shown to grow faster and exhibit higher ATP and sugar contents. Leaf microarray studies showed that many genes involved in microRNAs (miRNAs) and trans-acting siRNAs (tasiRNAs) biogenesis were significantly changed in the fast-growing lines. In this study, the sRNA profiles of the leaf and the root of 20-day-old plants were sequenced and the impacts of high energy status on sRNA expression were analyzed. Results: 9-13 million reads from each library were mapped to genome. miRNAs, tasiRNAs and natural antisense transcripts-generated small interfering RNAs (natsiRNAs) were identified and compared between libraries. In the leaf of OE lines, 15 known miRNAs increased in abundance and 9 miRNAs decreased in abundance, whereas in the root of OE lines, 2 known miRNAs increased in abundance and 9 miRNAs decreased in abundance.
