Functional characterization of the homeodomain leucine zipper i transcription factor AtHB13 reveals a crucial role in Arabidopsis development
(Oxford University Press, 2015-09)
AtHB13 is a homeodomain leucine zipper I transcription factor whose function in development is largely unknown. AtHB13 and AtHB23 mutant and silenced lines were characterized by expression studies, reciprocal crosses, ...
Arabidopsis AtHB7 and AtHB12 evolved divergently to fine tune processes associated with growth and responses to water stress
(Biomed Central, 2014-06)
Background: Arabidopsis AtHB7 and AtHB12 transcription factors (TFs) belong to the homeodomain-leucine zipper subfamily I (HD-Zip I) and present 62% amino acid identity. These TFs have been associated with the control of ...
Arabidopsis thaliana HomeoBox 1 (AtHB1), a Homedomain-Leucine Zipper I (HD-Zip I) transcription factor, is regulated by PHYTOCHROME-INTERACTING FACTOR 1 to promote hypocotyl elongation
(Wiley Blackwell Publishing, Inc, 2015-08)
Arabidopsis thaliana HomeoBox 1 (AtHB1) is a homeodomain-leucine zipper transcription factor described as a transcriptional activator with unknown function. Its role in A. thaliana development was investigated. AtHB1 ...
ATHB2 is a negative regulator of germination in Arabidopsis thaliana seeds
(Springer Nature, 2021-02)
The germination timing of seeds is of the utmost adaptive importance for plant populations. Light is one of the best characterized factors promoting seed germination in several species. The germination is also fnely regulated ...
AtHB23 participates in the gene regulatory network controlling root branching and reveals differences between secondary and tertiary roots
(Wiley Blackwell Publishing, Inc, 2019-08)
In Arabidopsis, lateral root (LR) development is mainly controlled by several known auxin-regulated transcription factors (TFs). Here, we show that AtHB23 (a homeodomain-leucine zipper I TF) participates in this intricate ...
Caracterización funcional de los factores de transcripción vegetales pertenecientes a la familia HD-Zip que participan en los mecanismos de respuesta al estrés
(2014-04-28)
Los factores de transcripción (FTs) HD-Zip I de Arabidopsis thaliana, AtHB12 y AtHB7, presentan una alta similitud de secuencia con NaHD20 de Nicotiana attenuata.
La expresión de NaHD20 se induce por tratamientos relacionados ...
Influencia de los patrones de expresión, la conservación y la divergencia de secuencias de los factores de transcripción HD-Zip I de Arabidopsis thaliana sobre su función biológica
(2017-02-16)
Los factores de transcripción (FT) de la familia homeodominio-cierre de leucinas (HD-Zip) son exclusivos de plantas y se clasifican en cuatro subfamilias. Los miembros de la subfamilia I participan principalmente de las ...
The homologous HD-Zip i transcription factors HaHB1 and AtHB13 confer cold tolerance via the induction of pathogenesis-related and glucanase proteins
(Wiley Blackwell Publishing, Inc, 2012-01)
Plants deal with cold temperatures via different signal transduction pathways. The HD-Zip I homologous transcription factors HaHB1 from sunflower and AtHB13 from Arabidopsis were identified as playing a key role in such ...
Identificación de las vías de señalización reguladas por factores de transcripción HD-Zip de plantas que derivan en características diferenciales de posible aplicación biotecnológica
(2021-11-30)
Los factores de transcripción (FTs) de tipo Homeodominio-cierre de leucinas (HD-Zip) I participan en el desarrollo vegetal y la respuesta a factores ambientales. En esta Tesis nos enfocamos en dos miembros de esta familia, ...
