Extracellular ATP, nitric oxide and superoxide act coordinately to regulate hypocotyl growth in etiolated Arabidopsis seedlings
(Elsevier Gmbh, 2009-12)
Etiolated Arabidopsis thaliana seedlings germinated in the presence of reducing buffers such as reduced gluthathione (GSH) and dithiothreitol (DTT) have altered morphology. GSH and DTT inhibited hypocotyl elongation in a ...
Hormonal modulation of photomorphogenesis-controlled anthocyanin accumulation in tomato (Solanum lycopersicum L. cv Micro-Tom) hypocotyls: Physiological and genetic studies
(ELSEVIER IRELAND LTD, 2010)
Hormones are likely to be important factors modulating the light-dependent anthocyanin accumulation. Here we analyzed anthocyanin contents in hypocotyls of near isogenic Micro-Tom (MT) tomato lines carrying hormone and ...
Azospirillum growth promotion is related to changes in ferulate and dehydrodiferulate contents in cell wall of inoculated cucumber seedlings hypocotyls
(2015-06)
Azospirillum brasilense is a well known plant growth-promoting rhizobacterium. Plant cell growth is constrained by the primary cell wall (CW) which contains polysaccharide-bound hydroxycinammic acids (HCAs). They derive ...
Supraoptimal ethylene acts antagonistically with exogenous gibberellins during Solanum lycopersicum (Solanaceae) hypocotyl growthDosis supraóptimas de etileno actúan antagónicamente con giberelinas exógenas durante el crecimiento del hipocótilo de Solanum lycopersicum (Solanaceae)
(Sociedad Argentina de Botánica, 2016-02)
In many plant species ethylene and gibberellins interact to regulate plant growth and development. In some cases, these hormones can act in a synergistic way whereas in others they can be antagonistic. To date, the control ...
Influence of seed color on germination performance and storage organ color in the high-Andean crop Lepidium meyenii (Maca)
(Taylor and Francis, 2021)
Maca (Lepidium meyenii) is a high-Andean crop whose subterranean storage organs (hypocotyls) show distinctive colors that are related to pharmacological properties. Little is known about seed color variation and its influence ...
Measurement of expansin activity and plant cell wall creep by using a commercial texture analyzer
(Pontificia Universidad Catolica de Valparaíso, 2017-03)
Background Expansins play an important role in cell wall metabolism and fruit softening. Determination of expansin activity is a challenging problem since it depends on measuring cell wall properties by using ad hoc ...
Convergence of constitutive photomorphogenesis 1 and phytochrome interacting factor signalling during shade avoidance
(Wiley, 2016-04)
Shade-avoidance responses require CONSTITUTIVE PHOTOMORPHOGENESIS 1 (COP1) but the mechanisms of action of COP1 under shade have not been elucidated. Using simulated shade and control conditions, we analysed: the transcriptome ...
Repression of shade-avoidance reactions by sunfleck induction of HY5 expression in Arabidopsis
(Wiley Blackwell Publishing, Inc, 2011-10)
The light environment provides signals that play a critical role in the control of stem growth in plants. The reduced irradiance and altered spectral composition of shade light promote stem growth compared with unfiltered ...
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 ...
