Improved mesophyll–bundle sheath connectivity is achieved via different mechanisms in C2 vs C4 Alternanthera

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3675-3686, June 2026.
Leaf anatomy and biochemistry of C3, C2, and C4 plants. Summary Connectivity between mesophyll (M) and bundle sheath (BS) cells must improve during the evolution of C4 photosynthesis to facilitate large metabolite fluxes between these cell types, but the trait combinations that enhance M–BS connectivity and the points at which these enhancements occur ...

Phytohormonal and Transcriptomic Mechanisms of Multigenerational Stress Memory in Wheat Under Weed Competition

open access: yesPlant, Cell &Environment, Volume 49, Issue 6, Page 3436-3454, June 2026.
ABSTRACT Multigenerational stress exposure induces stress memory in plants, influencing resource allocation, defence mechanisms, and productivity. Weed competition imposes both resource‐based (abiotic) and allelopathic (biotic) stress, engaging overlapping hormonal pathways.

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...
