Constructing and testing a genetic network for controlling seed germination in Arabidopsis
(2023-06-05)
The funiculus (FUN) is continuous with the chalazal seed coat (CSC) during seed development. We previously reported that AUXIN SIGNALING F-BOX PROTEIN 1 and 5 (AFB1 and 5) expressed in FUN and CSC suppress seed germination. ...
Loss-of-function mutants and overexpression lines of the Arabidopsis cyclin CYCA1;2/TARDY ASYNCHRONOUS MEIOSIS exhibit different defects in prophase-I meiocytes but produce the same abnormal meiotic products
(2014-11-17)
In Arabidopsis, loss-of-function mutations in the A-type cyclin CYCA1;2/TARDY ASYNCHRONOUS MEIOSIS (TAM) gene lead to the production of abnormal meiotic products including triads and dyads. Here we report that overexpression ...
AFB1 and 5 act maternally outside the seed to promote seed growth in Arabidopsis
(2018-07-14)
The plant hormone auxin in maternal tissues plays a major role in promoting seed growth. However, whether auxin affects seed growth in maternal tissues in or outside the seed is unclear. In the process of investigating the ...
CELLULASE6 and MANNANASE7 affect cell differentiation and silique dehiscence in Arabidopsis
(2017-06-19)
Cellulases, hemicellulases and pectinases play important roles in fruit development and maturation, but mutants with defects in the fruit have not been reported for cellulase or hemicellulase genes. Here we report the ...
Predicting maternal auxin-signaling networks for seed dormancy regulation in Arabidopsis
(2021-06-21)
Auxin, like ABA, promotes seed dormancy, but how auxin promotes seed dormancy is not well understood. In studying seed dormancy regulation, we found that AUXIN SIGNALING F-BOX PROTEIN 1 (AFB1) and 5 maternally promoted ...
