Metabolic responses to combined water deficit and salt stress in maize primary roots
Journal of Integrative Agriculture, 2021 Soil water deficit and salt stress are major limiting factors of plant growth and agricultural productivity. The primary root is the first organ to perceive the stress signals for drought and salt stress.

The roles of microRNAs in regulating root formation and growth in plants
Journal of Integrative Agriculture, 2022 MicroRNAs (miRNAs) are small (ca. 20–24 nucleotides) non-coding RNAs that have recently been recognized as key post-transcriptional modulators of gene expression; and they are involved in many biological processes in plants, such as root growth and ...

Water supply and not nitrate concentration determines primary root growth in Arabidopsis [PDF]
, 2011 Understanding how root system architecture (RSA) adapts to changing nitrogen and water availability is important for improving acquisition. A sand rhizotron system was developed to study RSA in a porous substrate under tightly regulated nutrient supply ...
