Singh K, Gupta S, Singh AP. Review: Nutrient-nutrient interactions governing underground plant adaptation strategies in a heterogeneous environment. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2024; 342:112024. [PMID: 38325661 DOI: 10.1016/j.plantsci.2024.112024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 12/20/2023] [Accepted: 02/01/2024] [Indexed: 02/09/2024]
Abstract
Plant growth relies on the mineral nutrients present in the rhizosphere. The distribution of nutrients in soils varies depending on their mobility and capacity to bind with soil particles. Consequently, plants often encounter either low or high levels of nutrients in the rhizosphere. Plant roots are the essential organs that sense changes in soil mineral content, leading to the activation of signaling pathways associated with the adjustment of plant architecture and metabolic responses. During differential availability of minerals in the rhizosphere, plants trigger adaptation strategies such as cellular remobilization of minerals, secretion of organic molecules, and the attenuation or enhancement of root growth to balance nutrient uptake. The interdependency, availability, and uptake of minerals, such as phosphorus (P), iron (Fe), zinc (Zn), potassium (K), nitrogen (N) forms, nitrate (NO3-), and ammonium (NH4+), modulate the root architecture and metabolic functioning of plants. Here, we summarized the interactions of major nutrients (N, P, K, Fe, Zn) in shaping root architecture, physiological responses, genetic components involved, and address the current challenges associated with nutrient-nutrient interactions. Furthermore, we discuss the major gaps and opportunities in the field for developing plants with improved nutrient uptake and use efficiency for sustainable agriculture.

Abstract
Based on the established efficient regeneration system for watercress in our laboratory, we optimized the processes of pretreatment, co-culture, and differentiation culture. Through GFP fluorescence and PCR identification, we successfully obtained transgenic watercress with the DR5 gene, which allowed us to investigate the distribution details of auxin in the growth process of watercress. Our findings provide an effective method for gene function research and lay the foundation for innovative utilization of germplasm resources of watercress.

Abstract
A well-developed root system is crucial for the rapid growth, asexual reproduction, and adaptation to the drought environments of the watercress. After analyzing the transcriptome of the watercress root system, we found that a high concentration of auxin is key to its adaptation to dry conditions. For the first time, we obtained DR5::EGFP watercress, which revealed the dynamic distribution of auxin in watercress root development under drought conditions. Via the application of naphthylphthalamic acid (NPA), 4-biphenylboronic acid (BBO), ethylene (ETH), abscisic acid (ABA), and other factors, we confirmed that auxin has a significant impact on the root development of watercress. Finally, we verified the role of auxin in root development using 35S::NoYUC8 watercress and showed that the synthesis of auxin in the root system mainly depends on the tryptophan, phenylalanine, and tyrosine amino acids (TAA) synthesis pathway. After the level of auxin increases, the root system of the watercress develops toward adaptation to dry environments. The formation of root aerenchyma disrupts the concentration gradient of auxin and is a key factor in the differentiation of lateral root primordia and H cells in watercress.
