Wheat wounding-responsive HD-Zip IV transcription factor GL7 is predominantly expressed in grain and activates genes encoding defensins
Plant Molecular Biology - Tập 101 - Trang 41-61 - 2019
Nataliya Kovalchuk, Wei Wu, Natalia Bazanova, Nicolas Reid, Rohan Singh, Neil Shirley, Omid Eini, Alexander A. T. Johnson, Peter Langridge, Maria Hrmova, Sergiy Lopato
Several classes of transcription factors are involved in the activation of defensins. A new type of the transcription factor responsible for the regulation of wheat grain specific defensins was characterised in this work. HD-Zip class IV transcription factors constitute a family of multidomain proteins. A full-length cDNA of HD-Zip IV, designated TaGL7 was isolated from the developing grain of bre...... hiện toàn bộ
Characterization and expression of Metallothionein-like genes in cotton
Plant Molecular Biology - Tập 31 - Trang 701-705 - 1996
Richard L. Hudspeth, Susan L. Hobbs, David M. Anderson, Kanniah Rajasekaran, John W. Grula
We have characterized cotton (Gossypium hirsutum L.) genes encoding type 1 metallothionein-like proteins that are highly expressed in roots. Little or no expression of these genes was detected in other organs and tissues. The deduced amino acid sequences have a high degree of similarity with type 1 metallothionein-like proteins from other plants, including a central hydrophobic domain flanked by c...... hiện toàn bộ
The PSI family of nuclear proteins is required for growth in arabidopsis
Plant Molecular Biology - Tập 86 - Trang 289-302 - 2014
Nils Stührwohldt, Jens Hartmann, Renate I. Dahlke, Claudia Oecking, Margret Sauter
PSI1 was identified as a gene that is co-expressed with the phytosulfokine (PSK) receptor genes PSKR1 and PSKR2 in Arabidopsis thaliana. It represents a plant-specific protein family of unknown function with six members in two clades. Clade 1 members PSI1, PSI2 and PSI3 were characterized in this study. All three are nuclear localized. A predicted N-terminal myristoylation site was functionally an...... hiện toàn bộ
Characterization of mango (Mangifera indica L.) transcriptome and chloroplast genome
Plant Molecular Biology - - 2014
M. Kamran Azim, Ishtaiq A. Khan, Yong Zhang
We characterized mango leaf transcriptome and chloroplast genome using next generation DNA sequencing. The RNA-seq output of mango transcriptome generated >12 million reads (total nucleotides sequenced >1 Gb). De novo transcriptome assembly generated 30,509 unigenes with lengths in the range of 300 to ≥3,000 nt and 67× depth of coverage. Blast searching against nonredundant nucleotide databases an...... hiện toàn bộ
The chloroplast DNAs of flax genotrophs
Plant Molecular Biology - Tập 1 - Trang 183-189 - 1982
David Coates, Christopher A. Cullis
The chloroplast DNA of L. usitatissimum var. “Stormont Cirrus” has been mapped with respect to the recognition sites for the enzymes SalP1, Sst1 and SalG1. It is a circular molecule of about 160 kilobasepairs, with an inverted repeat containing the rDNA. Comparisons between chloroplast DNA of uninduced and induced flax genotrophs show there to be no major structural differences.
The structure and organization of the luciferase gene in the photosynthetic dinoflagellate Gonyaulax polyedra
Plant Molecular Biology - Tập 36 - Trang 275-284 - 1998
Liming Li, J. Woodland Hastings
The structural features of dinoflagellate nuclei are distinct from those of other eukaryotes in several respects, and the mechanisms of DNA replication and transcription are almost completely unknown. In this study we investigated the structure and organization of the gene coding for luciferase (LCF), the enzyme catalyzing the bioluminescent reaction in the dinoflagellate Gonyaulax polyedra. The g...... hiện toàn bộ
Transcriptional regulation by abscisic acid in barley (Hordeum vulgare L.) seeds involves autoregulation of the transcription factor HvABI5
Plant Molecular Biology - Tập 57 Số 1 - Trang 21-34 - 2005
José A. Casaretto, Tuan‐Hua David Ho
WRKY1 regulates stomatal movement in drought-stressed Arabidopsis thaliana
Plant Molecular Biology - Tập 91 - Trang 53-65 - 2016
Zhu Qiao, Chun-Long Li, Wei Zhang
A key response of plants to moisture stress is stomatal closure, a process mediated by the phytohormone abscisic acid (ABA). Closure is affected by changes in the turgor of the stomatal guard cell. The transcription factor WRKY1 is a part of the regulatory machinery underlying stomatal movements, and through this, in the plant’s response to drought stress. The loss-of-function T-DNA insertion muta...... hiện toàn bộ
A comparison of the expression patterns of several senescence-associated genes in response to stress and hormone treatment
Plant Molecular Biology - Tập 37 - Trang 455-469 - 1998
Louis M. Weaver, Susheng Gan, Betania Quirino, Richard M. Amasino
The expression of several Arabidopsis thaliana senescence-associated genes (SAGs) in attached and/or detached leaves was compared in response to age, dehydration, darkness, abscisic acid, cytokinin, and ethylene treatments. Most of the SAGs responded to most of the treatments in a similar fashion. Detachment in darkness and ethylene were the strongest inducers of both SAGs and visible yellowing. D...... hiện toàn bộ
Identification of short promoter regions involved in the transcriptional expression of the nitrate reductase gene in Chlamydomonas reinhardtii
Plant Molecular Biology - - 2001
Roland Loppes, Michèle Radoux
In Chlamydomonas reinhardtii, the expression of the Nia1 gene encoding NAD(P)H nitrate reductase is controlled at the transcriptional level, positively by light and negatively by ammonium. Previous work has shown that the region −279 to +269 with respect to the start site of transcription was sufficient to confer regulated expression of a promoterless arylsulfatase (Ars) reporter gene. To understa...... hiện toàn bộ
