DAO1 catalyzes temporal and tissue-specific oxidative inactivation of auxin in Arabidopsis thaliana
(2016-09-27)
Tight homeostatic regulation of the phytohormone auxin [indole-3-acetic acid (IAA)] is essential to plant growth. Auxin biosynthetic pathways and the processes that inactivate auxin by conjugation to amino acids and sugars ...
High auxin and high phosphate impact on rsl2 expression and ros-homeostasis linked to root hair growth in arabidopsis thaliana
(Frontiers Research Foundation, 2018-08)
Root hair size determines the surface area/volume ratio of the whole roots exposed to the nutrient and water pools, thereby likely impacting nutrient and water uptake rates. The speed at which they grow is determined both ...
Arabidopsis thaliana SURFEIT1-like genes link mitochondrial function to early plant development and hormonal growth responses
(Wiley Blackwell Publishing, Inc, 2020-04)
Mutations in SURFEIT1 (SURF1) genes affect cytochrome c oxidase (COX) levels in different prokaryotic and eukaryotic organisms. In this work, we report that Arabidopsis thaliana has two genes that potentially encode SURF1 ...
ABA biosynthesis genes are down regulated while auxin and cytokinin biosynthesis genes are up-regulated during the release of grapevine buds from endodormancy
(Springer, 2017)
Auxin–cytokinin (CK) interactions have been
extensively studied in the control of bud outgrowth in herbaceous
plants. However, in temperate woody plants where
the meristem of dormant buds can be repressed by either
exogenous ...
Molecular link between auxin and ROS-mediated polar growth
(National Academy of Sciences, 2017-05)
Root hair polar growth is endogenously controlled by auxin and sustained by oscillating levels of reactive oxygen species (ROS). These cells extend several hundred-fold their original size toward signals important for plant ...
Multiple resistance evolution in Bipyridylium- resistant Epilobium ciliatum after recurrent selection
(Frontiers in Plant Science, 2019)
Induction of gibberellin 20-oxidases and repression of gibberellin 2b-oxidases in unfertilized ovaries of entire tomato mutant, leads to accumulation of active gibberellins and parthenocarpic fruit formation
(Springer, 2015-03)
In tomato (Solanum lycopersicum L.), auxin
and gibberellins (GAs) cross-talk plays an important role
during fruit-set. The entire tomato mutant has been previ-
ously reported to carry a deletion in the coding region ...
Effect of pollination and fertilization on the expression of genes related to floral transition, hormone synthesis and berry development in grapevine
(ELSEVIER GMBH, 2011)
In the present work, the effect of assisted fertilization on anatomical, morphological and gene expression changes occurring in carpels and during early stages of berry development in Vitis vinifera were studied. Inflorescences ...
