Organogenic events during gynoecium and fruit development in Arabidopsis
Curr Opin Plant Biol. 2023 Aug 24;75:102440. doi: 10.1016/j.pbi.2023.102440. Online ahead of print.ABSTRACTAngiosperms are the most successful group of land plants. This success is mainly due to the gynoecium, the innermost whorl of the flower. In Arabidopsis, the gynoecium is a syncarpic structure formed by two congenitally fused carpels. At the fusion edges of the carpels, the carpel margin meristem forms. This quasi-meristem is important for medial-tissue development, including the ovules. After the double fertilization, both the seeds and fruit begin to develop. Due to the importance of seeds and fruits as major food s...

Post-transcriptional and translational regulation of plant gene expression by transposons
Curr Opin Plant Biol. 2023 Aug 22;75:102438. doi: 10.1016/j.pbi.2023.102438. Online ahead of print.ABSTRACTTransposons are mobile DNA sequences that can move within the genome and integrate in new genomic locations. They are widespread in eukaryotes and prokaryotes and can influence gene expression when landing within or nearby a gene. Although transposon-induced regulation of gene expression at the transcriptional level has been extensively studied, there has been less focus on regulation at the post-transcriptional and translational levels. Recent studies in maize (Zea mays) and other plant species suggest that transposo...

Insights into the role of phytohormones in plant female germline cell specification
Curr Opin Plant Biol. 2023 Aug 19;75:102439. doi: 10.1016/j.pbi.2023.102439. Online ahead of print.ABSTRACTGermline specification is a fundamental process in plant reproduction, and the Megaspore Mother Cell (MMC), is a critical cell that differentiates and develops into the female gametophyte. While numerous studies have investigated the molecular mechanisms underlying female germline specification, previous reviews have mainly focused on gene regulatory networks, epigenetic pathways, and small RNAs, neglecting the potential contribution of phytohormones to this process. This review aims to address this gap by highlightin...

Moving targets: Mechanisms regulating siRNA production and DNA methylation during plant development
Curr Opin Plant Biol. 2023 Aug 18;75:102435. doi: 10.1016/j.pbi.2023.102435. Online ahead of print.ABSTRACTDNA methylation is a conserved modification that must be precisely regulated during development to facilitate its roles in silencing transposable elements and regulating gene expression. In plants, DNA methylation changes during reproduction are widely documented and, in many cases, the underlying mechanisms are well understood. In somatic tissues, the diversity of methylation patterns are only recently emerging but they are often associated with the RNA-directed DNA methylation (RdDM) pathway. Here, we discuss advanc...

Stochasticity in gene body methylation
Curr Opin Plant Biol. 2023 Aug 17;75:102436. doi: 10.1016/j.pbi.2023.102436. Online ahead of print.ABSTRACTGene body methylation (gbM) is a widely conserved epigenetic feature of plant genomes. Efforts to delineate the mechanisms by which gbM contributes to transcriptional regulation remain largely inconclusive, and its evolutionary significance continues to be debated. Curiously, although steady-state gbM levels are remarkably stable across mitotic and meiotic cell divisions, the methylation status of individual CG dinucleotides in gbM genes is highly stochastic. How can these two seemingly contradictory observations be r...

It is becoming clear how chromatin organization is linked to transcriptional regulation in response to environmental stresses. Regulation of specific chromatin positions in the nuclear space is important for transcription, and the mechanisms that enable such chromatin dynamics are gradually being unveiled.
