Cytokinin functions as an asymmetric and anti-gravitropic signal in lateral roots [PDF]
Nature Communications, 2019 Lateral roots emerge from the primary root at right angles but briefly grow asymmetrically to set a distinct growth angle. Here Waidmann et al. show that cytokinin acts as an anti-gravitropic signal that impairs growth on the upper side of emerged ...

Antigravitropic PIN polarization maintains non-vertical growth in lateral roots. [PDF]
Nat Plants, 2023 Lateral roots are typically maintained at non-vertical angles with respect to gravity. These gravitropic setpoint angles are intriguing because their maintenance requires that roots are able to effect growth response both with and against the gravity ...

Heterogeneous nutrient supply promotes maize growth and phosphorus acquisition: additive and compensatory effects of lateral roots and root hairs. [PDF]
Ann Bot, 2021 BACKGROUND AND AIMS Root proliferation is a response to heterogeneous nutrient distribution. However, the growth of root hairs in response to heterogeneous nutrients and the relationship between root hairs and lateral roots remain unclear.

Same same, but different: growth responses of primary and lateral roots. [PDF]
J Exp Bot, 2020 We highlight the similarities and differences in primary and lateral root growth, focusing on the differential impact that phytohormones and environmental cues have on these.

Two mechanisms regulate directional cell growth in Arabidopsis lateral roots. [PDF]
Elife, 2019 Morphogenesis in plants depends critically on directional (anisotropic) growth. This occurs principally perpendicular to the net orientation of cellulose microfibrils (CMFs), which is in turn controlled by cortical microtubules (CMTs).

Genome-wide analysis of long non-coding RNAs (lncRNAs) in tea plants (Camellia sinensis) lateral roots in response to nitrogen application [PDF]
Frontiers in Plant Science, 2023 Tea (Camellia sinensis) is one of the significant cash crops in China. As a leaf crop, nitrogen supply can not only increase the number of new shoots and leaves but also improve the tenderness of the former. However, a conundrum remains in science, which

Auxin Modulated Initiation of Lateral Roots Is Linked to Pericycle Cell Length in Maize. [PDF]
Front Plant Sci, 2019 Auxin is essential for the regulation of root system architecture by controlling primary root elongation and lateral root (LR) formation. Exogenous auxin has been reported to inhibit primary root elongation and promote the formation of LRs. In this study,

Nitrate: A Crucial Signal during Lateral Roots Development. [PDF]
Front Plant Sci, 2017 Root plasticity is an important trait for plants to forage nutrient and adapt to survival in a complicated environment. Lateral roots (LRs) are generally more sensitive than primary roots in response to changing environmental conditions.

Root type matters: measurement of water uptake by seminal, crown, and lateral roots in maize. [PDF]
J Exp Bot, 2018 We showed that crown roots have a different capacity to transport water compared with seminal roots. Acknowledging such differences between root types is crucial to understand optimal root traits.

Priming and positioning of lateral roots in Arabidopsis. An approach for an integrating concept. [PDF]
J Exp Bot, 2016 Highlight Lateral root pattern formation is controlled mechanistically by separate processes: oscillating priming signals determine lateral root frequency and mechanical cues determine their spatial positioning along the primary root.
