Hydrosensing will be featured on the 39th EPSO Plant Science Seminar

By Hydrosensing News

On 16th January 2025 at 15:00 (CET) Hydrosensing will be featured at the 39th EPSO Plant Science Seminar. We will present four talks exploring “Hydrosensing – an ERC Synergy Grant in Plant Sciences”

Hydropatterning responses revealed in public sector breeding lines of Zea mays (maize). (A and B) Schematic of the (A) hydropatterning response in (B) our custom-built hydropatterning assay. Primary roots of maize seedlings are grown in a vertical position along moist paper while being prevented from growing off the paper by a mesh cover. Lateral root (LR) primordia are preferentially induced towards the water-saturated paper (contact-side) and suppressed on the air-exposed side (air-side). Longitudinal cross-section of maize root (B73 inbred) stained with Calcofluor White (cell walls; gray) and SYBR Green (LRs; green). (C and D) Distribution of (C) contact-(blue) and air-side (white) LR densities from 250 maize inbred lines characterized using the hydropatterning assay and calculated (D) percent air-side LRs (purple). Each inbred line is represented by its median value (n = 1-3 seedlings/inbred) (data S2). Gray lines connect corresponding inbred lines. Population median (white circles). (E) X-ray Computed Tomography showing LR patterning on primary roots of strong (CI64) and weak (OH7B) hydropatterning inbred lines grown through an air-filled macropore in soil.

Roots employ several classes of hormones including rhizocrine signals that spend time outside of plant tissues in the rhizosphere. A schematic diagram illustrating (A) a longitudinal cross-section of a root growing in soil, and (D–E) examples of the contrasting modes of action for different hormone classes (denoted as yellow circles) involving (D) endocrine signalling (i.e. acting in other organs after long-distance transport), and (E) rhizocrine signalling, where this class of hormone moves outside its root source via the soil (denoted by the blue arrow), returning to the root in response to a soil stress (denoted by the red arrow), triggering an adaptive response, denoted by the green arrow and receptor binding of the hormone signal.

Hydrosensing launches on social media

By Hydrosensing News

We are thrilled to announce the official ONLINE launch of HYDROSENSING, a UE funded project backed by the European Research Council, — a ERC Synergy Project dedicated to unlock the secrets of how plants perceive and adapt to changing water conditions by pinpointing how ABA moves and acts within plants.
