Special Issue Information

Dear Colleagues,

Plant roots are vital organs that not only anchor plants to the soil, but also support above-ground growth by absorbing water and nutrients from the soil. This Special Issue titled "Plant Root: Anatomy, Structure, and Development" aims to provide a platform for researchers, scholars, and scientists to delve into the diverse aspects of plant roots. The scope encompasses a wide range of topics, including root anatomy, cellular and tissue-level structures, molecular mechanisms governing root development, environmental interactions, and the ecological significance of roots in terrestrial ecosystems. Contributors are encouraged to explore both fundamental and applied aspects of plant roots, offering a holistic view of this essential plant organ.

This Special Issue welcomes the submission of manuscripts, including original research, brief research reports, and review articles in (but not limited to) the following areas:

  1. Root Anatomy and Morphology: Explore the diverse anatomical structures and morphological adaptations of plant roots.
  2. Developmental Mechanisms: Investigate the molecular and genetic processes underlying root development.
  3. Root–Environment Interactions: Examine how roots respond to and interact with their surrounding environment, including soil, microorganisms, and stress factors.
  4. Root System Ecology: Explore the ecological roles of roots in nutrient cycling, soil stability, and ecosystem functioning.

Paddy fields are important anthropogenic emission sources of methane (CH4). However, it is not clear how rice root development and rhizosphere soil properties affect CH4 emissions. Therefore, we selected rice varieties with similar growth periods but different root traits in the local area. We measured CH4 emission fluxes, cumulative CH4 emissions, root dry weight, root length, and the dissolved organic carbon (DOC), microbial biomass carbon (MBC), redox potential (Eh), ammonium nitrogen (NH4+–N), and nitrate nitrogen (NO3−–N) contents in rhizosphere soil. Methanogens and methanotrophs are crucial factors influencing CH4 emissions; thus, their abundance and community composition were also assessed. The result showed that CH4 fluxes of each rice variety reached the peak at tillering stage and jointing-booting stage. The CH4 emissions in tillering stage were the largest in each growth period. CH4 emissions had negative correlations with root length, root dry weight, Eh NO3−–N, methanotroph abundance, and the pmoA/mcrA ratio, and positive correlations with NH4+–N, MBC, DOC, and methanogen abundance. Path analysis confirmed methanogens and methanotrophs as direct influences on CH4 emissions. Root development and rhizosphere soil properties affect CH4 emissions indirectly through these microbes. This study suggests that choosing rice varieties with good root systems and managing the rhizosphere soil can effectively reduce CH4 emissions. Full article

The maintenance of the root stem cell niche identity in Arabidopsis relies on the delicate balance of reactive oxygen species (ROS) levels in root tips; however, the intricate molecular mechanisms governing ROS homeostasis within the root stem cell niche remain unclear. In this study, we unveil the role of ATP hydrolase superfamily protein 1 (ASP1) in orchestrating root stem cell niche maintenance through its interaction with the redox regulator cystathionine β-synthase domain-containing protein 3 (CBSX3). ASP1 is exclusively expressed in the quiescent center (QC) cells and governs the integrity of the root stem cell niche. Loss of ASP1 function leads to enhanced QC cell division and distal stem cell differentiation, attributable to reduced ROS levels and diminished expression of SCARECROW and SHORT ROOT in root tips. Our findings illuminate the pivotal role of ASP1 in regulating ROS signaling to maintain root stem cell niche homeostasis, achieved through direct interaction with CBSX3. Full article

Abstract: The role of geneticists and breeders is to develop plants with root traits that enhance productivity under different environmental conditions. However, there is a need for a better understanding of root functional traits and how these traits relate to overall plant strategies to improve crop yield under different environmental conditions. The root morphology that promotes high crop yield varies under different soil conditions. For example, under drought conditions, roots tend to grow deep with thin root diameter and high root length density. Under salt stress conditions, greater root length, root surface area, root volume and root dry weight are beneficial for high yield. Under drought conditions, the smaller diameter of the xylem vessels can store water from deeper layers of the soil, which can be used by the crop during critical periods of water demand, thereby increasing yield. However, key questions remain: which root traits provide the greatest benefit for plant growth, and under what conditions do they operate? Therefore, this article mainly provides an overview of root anatomy and root morphology that contribute to crop yield enhancement under abiotic stress conditions and points out directions for further research.
