The effects of soil compaction on wheat seedling root growth are specific to soil texture and soil moisture status (2023)
Journal Article

Soil structure is a crucial soil physical property that determines a soil's ability to support the growth and development of plants. Soil compaction modifies soil structure by reducing pore space between soil particles thereby leading to a denser soi...

Soil structure has a greater effect on the rooting of wheat (Triticum aestivum L.) than nitrogen fertilisation rate or genotype (2023)
Journal Article

Despite extensive research over the last century concerning the application of nitrogen fertilizer to support the production of wheat (Triticum aestivum L.), our understanding on how this impacts on root growth in subsoils is limited. In this study,... Read More about Soil structure has a greater effect on the rooting of wheat (Triticum aestivum L.) than nitrogen fertilisation rate or genotype.

ERFVII action and modulation through oxygen-sensing in Arabidopsis thaliana (2023)
Journal Article

Oxygen is a key signalling component of plant biology, and whilst an oxygen-sensing mechanism was previously described in Arabidopsis thaliana, key features of the associated PLANT CYSTEINE OXIDASE (PCO) N-degron pathway and Group VII ETHYLENE RESPON...

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...

X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil (2022)
Journal Article

The spatial arrangement of the root system, termed root system architecture, is important for resource acquisition as it directly affects the soil zone explored. Methods for phenotyping roots are mostly destructive, which prevents analysis of roots o... Read More about X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil.

Plant roots sense soil compaction through restricted ethylene diffusion (2021)
Journal Article

© 2021 The Authors, some rights reserved. Soil compaction represents a major challenge for modern agriculture. Compaction is intuitively thought to reduce root growth by limiting the ability of roots to penetrate harder soils. We report that root gro...

CEP receptor signalling controls root system architecture in Arabidopsis and Medicago (2020)
Journal Article

© 2020 The Authors. New Phytologist © 2020 New Phytologist Trust Root system architecture (RSA) influences the effectiveness of resources acquisition from soils but the genetic networks that control RSA remain largely unclear. We used rhizoboxes, X-r... Read More about CEP receptor signalling controls root system architecture in Arabidopsis and Medicago.

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...

Soil seal development under simulated rainfall: structural, physical and hydrological dynamics (2017)
Journal Article

This study delivers new insights into rainfall-induced seal formation through a novel approach in the use of X-ray Computed Tomography (CT). Up to now seal and crust thickness have been directly quantified mainly through visual examination of sealed/...

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.

Comparative morphological trade-offs between pre- and post-copulatory sexual selection in Giant hissing cockroaches (Tribe: Gromphadorhini) (2016)
Journal Article

Sperm competition theory predicts that animals face a trade-off between investment in weaponry and investment in ejaculate composition. Within the Madagascan giant hissing cockroaches (Tribe Gromphadorhini) differences in morphology exist that may in...
