“…The absorption and transport of water under strong osmotic stress due to high soil salinity are crucial for growth and survival of mangrove plants 22,23,24,25 . Root anatomical structures, such as the stele and cortex, are directly related to root water absorption and transportation 26,27,28 , and the anatomical traits, hereafter termed root hydraulic traits or root hydraulics.…”

Interactions among root and leaf traits (in particular, leaf hydraulic and leaf economics traits) are fundamental in generating diverse strategies in land plants, yet it remains a knowledge gap in mangrove plants that experiences saline stress distinct from most other vascular plants. Here, we tested the trait relationships in mangrove plants and compared them with typical land plants (non-mangrove). Consistent with non-mangrove plants, leaf hydraulic and economics traits were decoupled in mangrove plants. However, mangrove leaf economics traits correlated strongly with root hydraulic traits, which are normally decoupled in non-mangrove plants. Moreover, we observed a unique scaling relationship between leaf dry mass per area and root hydraulic traits in mangroves. The novel coordination between leaves and roots arises from the wide-presence of leaf water storage tissues in mangroves, and this potentially represents a new paradigm with which we look into the ecology, physiology and evolution of this important vegetation.

SUMMARYThe osmotic resistance mechanism has been extensively studied in whole plants or plant tissues. However, little is known about it in embryogenic tissue (ET) which is widely used in plant‐based biotechnological systems. Suberin, a cell wall aliphatic and aromatic heteropolymer, plays a critical role in plant cells against osmosis stress. The suberin regulatory biosynthesis has rarely been studied in gymnosperms. Here, PaMYB11, a subgroup 11 R2R3‐MYB transcription factor, plays a key role in the osmotic resistance of Norway spruce (Picea abies) ETs during cryoprotectant pretreatment. Thus, RNA‐seq, histological, and analytical chemical analyses are performed on the stable transformations of PaMYB11‐OE and PaMYB11‐SRDX in Norway spruce ETs. DAP‐seq, Y1H, and LUC are further combined to explore the PaMYB11 targets. Activation of PaMYB11 is necessary and sufficient for suberin lamellae deposition on Norway spruce embryogenic cell walls, which plays a decisive role in ET survival under osmotic stress. Transcriptome analysis shows that PaMYB11 enhances suberin lamellae monomer synthesis by promoting very long‐chain fatty acid (VLCFA) synthesis. PaPOP, PaADH1, and PaTET8L, the first two (PaADH1 and PaPOP, included) involved in VLCFA synthesis, are proved to be the direct targets of PaMYB11. Our study identified a novel osmotic response directed by PaMYB11 in Norway spruce ET, which provides a new understanding of the resistance mechanism against osmosis in gymnosperms.
