HYL1's multiverse: A journey through miRNA biogenesis and beyond canonical and non-canonical functions of HYL1
Curr Opin Plant Biol. 2024 May 7;80:102546. doi: 10.1016/j.pbi.2024.102546. Online ahead of print.ABSTRACTA delicate balance in gene expression, a process highly controlled by post-transcriptional gene silencing mediated by miRNAs, is vital during plant growth and responses to stress. Within the miRNA biogenesis pathway, HYL1 is one of the most important proteins, initially recognized for its role as a cofactor of DCL1. Yet, HYL1's functions extend beyond miRNA processing, encompassing transcriptional regulation and protein translation between other recently discovered functions. This review comprehensively examines our cu...

The evolutionary and ecological significance of phylloclade formation: A morpho-anatomical approach
Curr Opin Plant Biol. 2024 May 5;79:102545. doi: 10.1016/j.pbi.2024.102545. Online ahead of print.ABSTRACTInstead of leaves, in a few species the main photosynthetic organ is a flattened structure that can be a modified branch (e.g. Ruscus, Jacksonia) or a fused combination of branch and leaf tissue (e.g. Phyllocladus) called a phylloclade. The phylloclades of Phyllocladus lack xeromorphic features in their wet habitat. They are broad under the low light conditions as are those of Ruscus which can occur in forest understories. However Ruscus is also common in dry habitats and shows numerous xeromorphic features. In Jackson...

Creating an explosion: Form and function in explosive fruit
Curr Opin Plant Biol. 2024 Apr 29;79:102543. doi: 10.1016/j.pbi.2024.102543. Online ahead of print.ABSTRACTAdaptations for seed dispersal are found everywhere in nature. However, only a fraction of this diversity is accessible through the study of model organisms. For example, Arabidopsis seeds are released by dehiscent fruit; and although many genes required for dehiscence have been identified, the genetic basis for the vast majority of seed dispersal strategies remains understudied. Explosive fruit generate mechanical forces to launch seeds over a wide area. Recent work indicates that key innovations required for explosi...

Beauty is more than epidermis deep: How cell division and expansion sculpt the leaf spongy mesophyll
Curr Opin Plant Biol. 2024 Apr 29;79:102542. doi: 10.1016/j.pbi.2024.102542. Online ahead of print.ABSTRACTAs the main location of photosynthesis, leaf mesophyll cells are one of the most abundant and essential cell types on earth. Forming the bulk of the internal tissues of the leaf, their size, shape, and patterns of interconnectivity define the internal structure and surface area of the leaf, which in turn determines the efficiency of light capture and carbon fixation. Understanding how these cellular traits are controlled and translated into tissue- and organ-scale traits, and how they influence photosynthetic performa...

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...
