Canvis epigenètics en resposta a elevades temperatures en Arabidopsis
(Universitat Politècnica de Catalunya, 2023-09-14)
Treball Final de Grau
Accés obertThe chromatin remodeling protein LIKE HETEROCHROMATIN PROTEIN1 (LHP1) participates in the transcriptional regulation of a wide variety of genes. It is known that the mechanism for doing this is through Polycomb activity ... -
Current perspectives on the hormonal control of seed development in Arabidopsis and maize: a focus on auxin.
(2014)
Article
Accés obertThe seed represents the unit of reproduction of flowering plants, capable of developing into another plant, and to ensure the survival of the species under unfavorable environmental conditions. It is composed of three ... -
DRACULA2 is a dynamic nucleoporin with a role in regulating the shade avoidance syndrome in Arabidopsis
(2016)
Article
Accés obertWhen plants grow in close proximity basic resources such as light can become limiting. Under such conditions plants respond to anticipate and/or adapt to the light shortage, a process known as the shade avoidance syndrome ... -
Especificidad de los componentes antivirales vegetales por tipos celulares
(Universitat Politècnica de Catalunya, 2023-02-15)
Treball Final de Grau
Accés obert
Realitzat a/amb: Centre for Research in Agricultural GenomicsGene silencing is a cellular mechanism by which gene expression is inhibited in eukaryotic organisms. It is present in both endogenous and exogenous control nucleic acids and is classified as transcriptional gene silencing ... -
Estudi dels canvis en la cromatina en resposta a proximitat vegetal en diferents estadis del desenvolupament d'Arabidopsis
(Universitat Politècnica de Catalunya, 2023-07-18)
Treball Final de Grau
Accés obert
Realitzat a/amb: Universitat Autònoma de BarcelonaPlants have mechanisms to cope with changes in the surrounding environment. One of them is the shade avoidance syndrome (SAS), thanks to which, through changes in gene expression, they adapt their development to the quality ... -
Generació de vectors de clonació i transformació transitòria de Nicotiana benthamiana per a l’estudi d’interaccions proteïna-proteïna mitjançant la tècnica TurboID
(Universitat Politècnica de Catalunya, 2023-10-30)
Treball Final de Grau
Accés obertIn high plant density conditions, plants detect changes in the quality of the light they receive and activate a system called the "shade avoidance syndrome", which involves a series of changes in their development to compete ... -
Genome-wide analysis of the emigrant family of MITEs: amplification dynamics and evolution of genes in Arabidopsis thaliana
(2002-01)
Report de recerca
Accés obertMITEs are structurally similar to defective class II elements but their high copy number and the size and sequence conservation of most MITE families suggest that they can be amplified by a replicative mechanism. Here ... -
Identification of key sequence features required for microRNA biogenesis in plants
(Nature Research, 2020)
Article
Accés obertMicroRNAs (miRNAs) are endogenous small RNAs of ∼21 nt that regulate multiple biological pathways in multicellular organisms. They derive from longer transcripts that harbor an imperfect stem-loop structure. In plants, the ... -
Maternal control of PIN1 is required for female gametophyte development in Arabidopsis
(Public Library of Science (PLOS), 2013)
Article
Accés obertLand plants are characterised by haplo-diploid life cycles, and developing ovules are the organs in which the haploid anddiploid generations coexist. Recently it has been shown that hormones such as auxin ... -
Molecular and physiological study of light regulation of plant development
(Universitat Politècnica de Catalunya, 2020-11-26)
Treball Final de Grau
Accés obertA plant can detect a possible situation of shade by perceiving changes in the ratio between Red light and Far Red light (R:FR ratio). When it detects it, a wide network of components is activated. If the plant is a ... -
Ovule development, a new model for lateral organ formation
(2014)
Article
Accés obertIn spermatophytes the ovules upon fertilization give rise to the seeds. It is essential to understand the mechanisms that control ovule number and development as they ultimately determine the final number of seeds and, ... -
Paper del factor de transcripció PIF7 en la remodelació de cromatina
(Universitat Politècnica de Catalunya, 2023-07-26)
Treball Final de Grau
Accés obertQuan hi ha canvis ambientals, aquests són percebuts per les plantes, les quals poden respondre modificant el seu desenvolupament per adaptar-se a la nova situació. Les senyals ambientals són captades per receptors, que ... -
PAR1 and PAR2 integrate shade and hormone transcriptional networks
(2008)
Article
Accés restringit per política de l'editorialPHYTOCHROME RAPIDLY REGULATED1 (PAR1) and PAR2 are two negative regulators of shade avoidance syndrome (SAS) responses in Arabidopsis. PAR1 and PAR2 belong to the bHLH family of transcription factors and act as direct ... -
Photoreceptor activity contributes to contrasting responses to shade in cardamine and arabidopsis seedlings
(American Society of Plant Biologists, 2019-09-17)
Article
Accés obertPlants have evolved two major ways to deal with nearby vegetation or shade: avoidance and tolerance. Moreover, someplants respond to shade in different ways; for example, Arabidopsis (Arabidopsis thaliana) undergoes an ... -
