To compete for nutrients in diverse soil microenvironments, plants proliferate lateral roots
preferentially in nutrient-rich zones. For nitrate, root foraging involves local and systemic …

Nitrate distribution in soils is often heterogeneous. Plants have adapted to this by modifying
their root system architecture (RSA). Previous studies showed that NITRATE …

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 …

Plants have evolved adaptive strategies that involve transcriptional networks to cope with
and survive environmental challenges. Key transcriptional regulators that mediate …

Highlights•Systems analyses allowed for the identification of TGA1/TGA4 and NAC4,
important transcription factors controlling root system architecture in response to …

Root system architecture (RSA) is required for the acquisition of water and mineral nutrients
from the soil. One of the essential nutrients, nitrate (NO3−), is sensed and transported by …

Nitrate can affect many aspects of plant growth and development, such as promoting root
growth and inhibiting the synthesis of secondary metabolites. However, the mechanisms …

In Arabidopsis the plasma membrane nitrate transceptor (transporter/receptor) NRT1. 1
governs many physiological and developmental responses to nitrate. Alongside facilitating …

When the root systems of many plant species are exposed to a localized source of nitrate
(NO_3^- they respond by proliferating their lateral roots to colonize the nutrient-rich zone …

Nitrate acts as a potent signal to control global gene expression in A rabidopsis. Using an
integrative bioinformatics approach we identified TGA 1 and TGA 4 as putative regulatory …
