Macropore effects on phosphorus acquisition by wheat roots – a rhizotron study

Plant and Soil, 2017
Macropores may be preferential root pathways into the subsoil. We hypothesised that the presence of macropores promotes P-uptake from subsoil, particularly at limited water supply in surface soil. We tested this hypothesis in a rhizotron experiment with spring wheat (Triticum aestivum cv.

Diversity of Root System Architecture in Mediterranean Maize Inbred Lines Provides New Breeding Opportunities to Improve Stress Resilience and Resource Efficiency. [PDF]

Plants (Basel)
A detailed characterization of root system architecture (RSA) and growth dynamics is key to develop stress-resilient maize varieties. We evaluated sixty-five Mediterranean maize inbred lines using automated high-throughput phenotyping under controlled ...

Phenotypic Diversity in Pre- and Post-Attachment Resistance to Striga hermonthica in a Core Collection of Rice Germplasms. [PDF]

Plants (Basel), 2022
In sub-Saharan Africa, upland rice cultivation is expanding into rainfed areas endemic to the root parasitic weed Striga hermonthica. We evaluated the Striga resistance of 69 accessions from the World Rice Core Collection (WRC) to estimate the phenotypic

Organ-specific terpenoid responses in Tanacetum vulgare are chemotype-dependent. [PDF]

Plant Biol (Stuttg)
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Effect of phosphorus deficiency on biomass and root system architecture in diverse <i>Medicago</i> accessions. [PDF]

Front Plant Sci
IntroductionPhosphorus (P) is essential for legume growth and symbiotic nitrogen fixation, yet its low availability in many soils frequently constrains plant productivity.MethodsTo evaluate phenotypic and genotypic variation in P efficiency, 200 ...

Spatial-Temporal Dynamics of Adventitious Roots of Typha domingensis Pers. Seedlings Grown with Auxin/Cytokinin. [PDF]

Life (Basel)
The spatial–temporal dynamics of an in vitro radicular system of Typha domingensis for the development of rhizofiltration technologies, with the potential for use as a phytotreatment of eutrophicated water, were studied for the first time in the roots of

Recurrent summer drought temporarily stimulates fine root growth but enhances winter root losses in alpine grassland. [PDF]

Front Plant Sci
By the end of the 21st century, frequent droughts and substantial shifts in snowmelt are expected to massively impact the biomass production of alpine grasslands.

Isoprene-Emitting Transgenic Tobacco Shapes Root Microbiome and Enhances Growth of Co-Cultivated Non-Emitting Plants. [PDF]

Plant Cell Environ
ABSTRACT Isoprene is the most abundant biogenic volatile organic compound emitted by terrestrial vegetation. Here we report the impact of isoprene on root‐associated microbiomes. Using isoprene‐emitting (IE) transgenic tobacco and isogenic non‐emitting (NE) controls, we performed co‐cultivation experiments in natural soil and analysed plant phenotypes ...

Phenotyping Tomato Root Developmental Plasticity in Response to Salinity in Soil Rhizotrons [PDF]

Plant Phenomics, 2021
Plants have developed multiple strategies to respond to salt stress. In order to identify new traits related to salt tolerance, with potential breeding application, the research focus has recently been shifted to include root system architecture (RSA) and root plasticity. Using a simple but effective root phenotyping system containing soil (rhizotrons),
