Cell Type-Specific Gene Expression Analyses by RNA Sequencing Reveal Local High Nitrate-Triggered Lateral Root Initiation in Shoot-Borne Roots of Maize by Modulating Auxin-Related Cell Cycle Regulation.
Plants have evolved a unique plasticity of their root system architecture to flexibly exploit heterogeneously distributed mineral elements from soil. Local high concentrations of nitrate trigger lateral root initiation in adult shoot-borne roots of maize (Zea mays) by increasing the frequency of early divisions of phloem pole pericycle cells. Gene expression profiling revealed that, within 12 h...
متن کاملRoot-type-specific plasticity in response to localized high nitrate supply in maize (Zea mays).
BACKGROUND AND AIMS Shoot-borne roots contribute to most of the nutrient uptake throughout the life cycle of maize (Zea mays). Compared with numerous studies with embryonic roots, detailed information on the phenotypic plasticity of shoot-borne roots in response to a heterogeneous nitrogen supply is scarce. The present study therefore provides a comprehensive profile of fine-scale plastic respo...
متن کاملThe putative high-affinity nitrate transporter NRT2.1 represses lateral root initiation in response to nutritional cues.
Lateral root initiation is strongly repressed in Arabidopsis by the combination of high external sucrose and low external nitrate. A previously isolated mutant, lin1, can overcome this repression. Here, we show that lin1 carries a missense mutation in the NRT2.1 gene. Several allelic mutants, including one in which the NRT2.1 gene is completely deleted, show similar phenotypes to lin1 and fail ...
متن کاملThe optimal lateral root branching density for maize depends on nitrogen and phosphorus availability.
Observed phenotypic variation in the lateral root branching density (LRBD) in maize (Zea mays) is large (1-41 cm(-1) major axis [i.e. brace, crown, seminal, and primary roots]), suggesting that LRBD has varying utility and tradeoffs in specific environments. Using the functional-structural plant model SimRoot, we simulated the three-dimensional development of maize root architectures with varyi...
متن کاملLateral Root Inducible System in Arabidopsis and Maize.
Lateral root development contributes significantly to the root system, and hence is crucial for plant growth. The study of lateral root initiation is however tedious, because it occurs only in a few cells inside the root and in an unpredictable manner. To circumvent this problem, a Lateral Root Inducible System (LRIS) has been developed. By treating seedlings consecutively with an auxin transpo...
