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...

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...

Emergent Protective Organogenesis in Date Palms: A Morpho-devo-dynamic Adaptive Strategy During Early Development (2019)
Journal Article

Desert plants have developed mechanisms for adapting to hostile desert conditions, yet these mechanisms remain poorly understood. Here, we describe two unique modes used by desert date palms (Phoenix dactylifera L.) to protect their meristematic tiss...

Rice auxin influx carrier OsAUX1 facilitates root hair elongation in response to low external phosphate (2018)
Journal Article

Root traits such as root angle and hair length influence resource acquisition particularly for immobile nutrients like phosphorus (P). Here, we attempted to modify root angle in rice by disrupting the OsAUX1 auxin influx transporter gene in an effort...

Roots-eye view: using microdialysis and microCT to non-destructively map root nutrient depletion and accumulation zones (2017)
Journal Article

Improvement in fertiliser use efficiency is a key aspect for achieving sustainable agriculture in order to minimise costs, greenhouse gas emissions and pollution from nutrient runoff. To optimise root architecture for nutrient uptake and efficiency w...

Shaping 3D root system architecture (2017)
Journal Article

Plants are sessile organisms rooted in one place. The soil resources that plants require are often distributed in a highly heterogeneous pattern. To aid foraging, plants have evolved roots whose growth and development are highly responsive to soil si... Read More about Shaping 3D root system architecture.

Root hydrotropism is controlled via a cortex-specific growth mechanism (2017)
Journal Article

Plants can acclimate by using tropisms to link the direction of growth to environmental conditions. Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but whose molecular and cellular basis remains unclear...

Non-destructive determination of floral staging in cereals using X-ray micro computed tomography (µCT) (2017)
Journal Article

Background Accurate floral staging is required to aid research into pollen and flower development, in particular male development. Pollen development is highly sensitive to stress and is critical for crop yields. Research into male development under...
