SCI1 Is a Direct Target of AGAMOUS and WUSCHEL and Is Specifically Expressed in the Floral Meristematic Cells
(Frontiers Media, 2021-03-18)
The specified floral meristem will develop a pre-established number of floral organs and, thus, terminate the floral meristematic cells. The floral meristematic pool of cells is controlled, among some others, by WUSCHEL ...
Tomato Abscisic Acid Stress ripening (ASR) gene family revisited
(PLOS, 2014-10-13)
Tomato ABSCISIC ACID RIPENING 1 (ASR1) was the first cloned plant ASR gene. ASR orthologs were then cloned from a large number of monocot, dicot and gymnosperm plants, where they are mostly involved in response to abiotic ...
Class I TCP transcription factors activate the SAUR63 gene subfamily in gibberellin-dependent stamen filament elongation
(American Society of Plant Biologist, 2020-01)
In autogamous plants like Arabidopsis (Arabidopsis thaliana), stamen filament elongation must be finely regulated to ensure that anthers reach the pistil at the correct developmental stage. In this work, we studied the ...

Oligomerization studies show that the kinase domain of the tomato pollen receptor kinase LePRK2 is necessary for interaction with LePRK1
(Elsevier France-editions Scientifiques Medicales Elsevier, 2012-04)
LePRK1 and LePRK2 are two pollen-specific receptor-like kinases from Solanum lycopersicum that are involved in signaling during pollen-pistil communication. Previously, we showed that both proteins interact in pollen and ...
Differential methylation patterns in apomictic vs. Sexual genotypes of the diplosporous grass Eragrostis curvula
(Multidisciplinary Digital Publishing Institute, 2021-05-10)
DNA methylation is an epigenetic mechanism by which a methyl group is added to a cytosine or an adenine. When located in a gene/regulatory sequence it may repress or de-repress genes, depending on the context and species. ...
Reproductive biology of duodichogamous Koelreuteria elegans (Sapindaceae): the rare case of a female–male–female flowering sequence
(Csiro Publishing, 2019-05)
Monoecious species are common within Sapindaceae, and among them a large variation in sexual expression has been reported. In this work we evaluate the sexual expression, phenology, floral biology, and mating system in ...
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 ...
Genetic diversity and reproductive biology of the dioecious and epiphytic bromeliad Aechmea mariae-reginae (Bromeliaceae) in Costa Rica: implications for its conservation
(2019)
Ecological traits and pollination mode associated with dioecious sexual expression in plants are likely to influence
their reproductive success and levels of genetic diversity. Dioecy is an uncommon condition in Bromeliaceae. ...
