New insights into the functional roles of reactive oxygen species during embryo sac development and fertilization in Arabidopsis thaliana
(Taylor & Francis, 2013-10)
Previously considered as toxic by-products of aerobic metabolism, reactive oxygen species (ROS) are emerging as essential signaling molecules in eukaryotes. Recent evidence showed that maintenance of ROS homeostasis during ...
PATELLINS are regulators of auxin-mediated PIN1 relocation and plant development in Arabidopsis thaliana
(Company of Biologists, 2018)
Coordinated cell polarization in developing tissues is a recurrent theme in multicellular organisms. In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback ...
The MED30 subunit of mediator complex is essential for early plant development and promotes flowering in arabidopsis thaliana
(Company of Biologists, 2019-05)
Mediator is a large multiprotein complex that is required for the transcription of most, if not all, genes transcribed by RNA Polymerase II. A core set of subunits is essential to assemble a functional Mediator in vitro ...
Arabidopsis thaliana embryo sac mitochondrial membrane potential stain
(Bio-protocol LLC, 2014-05)
The aim of this experiment is to study mitochondrial functional status in Arabidopsis embryo sacs using the membrane potential indicator JC-1. Changes in the membrane potential are presumed to be due to the opening of the ...
Arabidopsis Qc‑SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation
(2015-10-01)
Pollen tubes are rapidly growing specialized structures that elongate in a polar manner. They play a crucial role in the delivery of sperm cells through the stylar tissues of the flower and into the embryo sac, where the ...

Lack of cytochrome c in Arabidopsis decreases stability of Complex IV and modifies redox metabolism without affecting Complexes i and III
(Elsevier Science, 2012-07)
We studied the role of cytochrome c (CYTc), which mediates electron transfer between Complexes III and IV, in cellular events related with mitochondrial respiration, plant development and redox homeostasis. We analyzed ...
The DC1-domain protein VACUOLELESS GAMETOPHYTES is essential for development of female and male gametophytes in Arabidopsis
(Wiley Blackwell Publishing, Inc, 2017-01-20)
In this work we identified VACUOLELESS GAMETOPHYTES (VLG) as a DC1 domain-containing protein present in the endomembrane system and essential for development of both female and male gametophytes. VLG was originally annotated ...
