Tracking the messengers: Emerging advances in mRNA-based plant communication
Curr Opin Plant Biol. 2024 Apr 24;79:102541. doi: 10.1016/j.pbi.2024.102541. Online ahead of print.ABSTRACTMessenger RNAs (mRNAs) are the templates for protein translation but can also act as non-cell-autonomous signaling molecules. Plants input endogenous and exogenous cues to mobile mRNAs and output them to local or systemic target cells and organs to support specific plant responses. Mobile mRNAs form ribonucleoprotein (RNP) complexes with proteins during transport. Components of these RNP complexes could interact with plasmodesmata (PDs), a major mediator of mRNA transport, to ensure mRNA mobility and transport selecti...

ROS are universal cell-to-cell stress signals
Curr Opin Plant Biol. 2024 Apr 20;79:102540. doi: 10.1016/j.pbi.2024.102540. Online ahead of print.ABSTRACTThe interplay between reactive oxygen species (ROS) and the redox state of cells is deeply rooted in the biology of almost all organisms, regulating development, growth, and responses to the environment. Recent studies revealed that the ROS levels and redox state of one cell can be transmitted, as an information 'state' or 'currency', to other cells and spread by cell-to-cell communication within an entire community of cells or an organism. Here, we discuss the different pathways that mediate cell-to-cell signaling in...

Spatiotemporal regulation of plant cell division

Online ahead of print.ABSTRACTPlant morphogenesis largely depends on the orientation and rate of cell division and elongation, and their coordination at all levels of organization. Despite recent progresses in the comprehension of pathways controlling division plane determination in plant cells, many pieces are missing to the puzzle. For example, we have a partial comprehension of formation, function and evolutionary significance of the preprophase band, a plant-specific cytoskeletal array involved in premitotic setup of the division plane, as wel...

Talk to your neighbors in an emergency: Stromule-mediated chloroplast-nucleus communication in plant immunity
Curr Opin Plant Biol. 2024 Apr 10;79:102529. doi: 10.1016/j.pbi.2024.102529. Online ahead of print.ABSTRACTHypersensitive response-programmed cell death (HR-PCD) is a response mounted by plants to defend themselves against pathogens. Communication between the chloroplast and the nucleus is critical for the progression of HR-PCD. Tubular protrusions of chloroplasts, known as stromules, are tightly associated with the HR-PCD progression. There is emerging evidence that signaling molecules originating from chloroplasts are transferred to the nucleus through stromules. The translocation of signaling molecules from the chloropl...

Finding the right balance: The enduring role of florigens during cereal inflorescence development and their influence on fertility
Curr Opin Plant Biol. 2024 Apr 9;79:102539. doi: 10.1016/j.pbi.2024.102539. Online ahead of print.ABSTRACTFlowering is a vital process in a plant's lifecycle and variation for flowering-time has helped cereals adapt to diverse environments. Much cereal research has focused on understanding how flowering signals, or florigens, regulate the floral transition and timing of ear emergence. However, flowering genes also perform an enduring role during inflorescence development, with genotypes that elicit a weaker flowering signal producing more elaborately branched inflorescences with extra floret-bearing spikelets. While this o...
