Root plasticity vs. elasticity – When are responses acclimative? (2024)
Journal Article

Spatiotemporal soil heterogeneity and the resulting edaphic stress cycles can be decisive for crop growth.

In Arabidopsis (Arabidopsis thaliana), AUX1 is... Read More about Mechanistic insight into the role of AUXIN RESISTANCE4 in trafficking of AUXIN1 and LIKE AUX1-2.

Turning up the volume: How root branching adaptive responses aid water foraging (2023)
Journal Article

Access to water is critical for all forms of life. Plants primarily access water through their roots. Root traits such as branching are highly sensitive to water availability, enabling plants to adapt their root architecture to match soil moisture di...

Transcription factor bHLH121 regulates root cortical aerenchyma formation in maize (2023)
Journal Article

Root anatomical phenotypes present a promising yet underexploited avenue to deliver major improvements in yield and climate resilience of crops by improving water and nutrient uptake. For instance, the formation of root cortical aerenchyma (RCA) sign... Read More about Transcription factor bHLH121 regulates root cortical aerenchyma formation in maize.

Hydraulic flux–responsive hormone redistribution determines root branching (2022)
Journal Article

Plant roots exhibit plasticity in their branching patterns to forage efficiently for heterogeneously distributed resources, such as soil water. The xerobranching response represses lateral root formation when roots lose contact with water. Here, we s...

Modeling root loss reveals impacts on nutrient uptake and crop development (2022)
Journal Article

Abstract Despite the widespread prevalence of root loss in plants, its effects on crop productivity are not fully understood. While root loss reduces the capacity of plants to take up water and nutrients from the soil, it may provide benefits by decr...

Root angle is controlled by EGT1in cereal crops employing anantigravitropic mechanism (2022)
Journal Article

Root angle in crops represents a key trait for efficient capture of soil resources. Root angle is determined by competing gravitropic versus anti-gravitropic offset (AGO) mechanisms. Here we report a new root angle regulatory gene termed ENHANCED GRA... Read More about Root angle is controlled by EGT1in cereal crops employing anantigravitropic mechanism.

Ethylene inhibits rice root elongation in compacted soil via ABA- and auxin-mediated mechanisms (2022)
Journal Article

Soil compaction represents a major agronomic challenge, inhibiting root elongation and impacting crop yields. Roots use ethylene to sense soil compaction as the restricted air space causes this gaseous signal to accumulate around root tips. Ethylene...

Root system size and root hair length are key phenes for nitrate acquisition and biomass production across natural variation in Arabidopsis (2022)
Journal Article

The role of root phenes in nitrogen (N) acquisition and biomass production was evaluated in 10 contrasting natural accessions of Arabidopsis thaliana L. Seedlings were grown on vertical agar plates with two different nitrate supplies. The low N treat...

Systems approaches reveal that ABCB and PIN proteins mediate co-dependent auxin efflux (2022)
Journal Article

Members of the B family of membrane-bound ATP-binding cassette (ABC) transporters represent key components of the auxin-efflux machinery in plants.
