EAT1 promotes tapetal cell death by regulating aspartic proteases during male reproductive development in rice.
It is demonstrated that ETERNAL TAPETUM 1 promotes aspartic proteases triggering plant programmed cell death, and reveals a dynamic regulatory cascade in male reproductive development in rice.
Plant Peroxisomes: Biogenesis and Function
Knowledge gained from plant peroxisomal research will be instrumental to fully understanding the organelle’s dynamic behavior and defining peroxISomal metabolic networks, thus allowing the development of molecular strategies for rational engineering of plant metabolism, biomass production, stress tolerance, and pathogen defense.
A Role for Peroxisomes in Photomorphogenesis and Development of Arabidopsis

Peroxisomes, whose functions are still largely unexplored, play a key role in a photomorphogenetic pathway negatively regulated by the DET1 and COP proteins.
Rice MADS3 Regulates ROS Homeostasis during Late Anther Development[W][OA]
It is suggested that MADS3 is a key transcriptional regulator that functions in rice male reproductive development, at least in part, by modulating ROS levels through MT-1-4b.
Peroxisome Biogenesis and Function
This review focuses on the advances in the understanding of peroxisome biogenesis and metabolism, and further explores the contribution of large-scale analysis, such as in sillco predictions and proteomics, in augmenting the knowledge of perxisome function In Arabidopsis.
Arabidopsis RING peroxins are E3 ubiquitin ligases that interact with two homologous ubiquitin receptor proteins(F).
The results suggest that Arabidopsis RING peroxins can function as E3 ligases and act together with the ubiquitin receptor protein DSK2 in the peroxisomal membrane-associated protein degradation system.
In-Depth Proteome Analysis of Arabidopsis Leaf Peroxisomes Combined with in Vivo Subcellular Targeting Verification Indicates Novel Metabolic and Regulatory Functions of Peroxisomes1[W][OA]
An in-depth proteome analysis of Arabidopsis (Arabidopsis thaliana) leaf peroxisomes is performed using one-dimensional gel electrophoresis followed by liquid chromatography and tandem mass spectrometry to establish the tripeptides SLM and SKV as new PTS1s and the nonapeptide RVx5HF as a putative new PTS2.
Jasmonic acid regulates spikelet development in rice.
A previously unknown role of the plant hormone jasmonic acid (JA) in determining rice (Oryza sativa) spikelet morphogenesis is reported and the role of JA in reproduction has diversified during the flowering plant evolution.
The PEROXIN11 Protein Family Controls Peroxisome Proliferation in Arabidopsis[W]
It is concluded that all five Arabidopsis PEX11 proteins promote peroxisome proliferation and that individual family members play specific roles in distinctPeroxisomal subtypes and environmental conditions and possibly in different steps of peroxISome proliferation.
A crucial role for the putative Arabidopsis topoisomerase VI in plant growth and development
The results suggest that BIN3 and BIN5 may constitute an Arabidopsis topoisomerase VI that modulates expression of many genes, including those regulated by BRs.
