Out of sight, out of mind

The proverb "Out of sight, out of mind" cannot find a better analogy than roots of higher plants. Historically, plant roots have been systematically ignored by scientists (Eshel & Beeckman, 2013). Perhaps it is very difficult to change perception, especially because the stalwarts of natural sciences chose to overlook the importance of plant roots. It is obvious that our very existence and the environment in which we live depend on plant roots and over a 100 years ago, Charles Darwin compared it to "the brain of one of the lower animals" in his book titled "The Power of Movement in Plants" published in 1897 (Darwin & Darwin, 2022). However, decades of apathy by the scientific community have led to a perception that roots are somewhat simple and relatively passive absorptive organs of plants that are unimportant and not worth studying. This perception trickles down to students, researchers, universities, institutions, and funding agencies who might not see any financial gains or career prospects involving root biology and allowed them to remain grounded deep in mystery.However, development in technology in the past decade have allowed scientists to investigate roots in greater details and the results show that roots are extremely plastic, dynamic, complex, and "intelligent" organs that associate with microbes, forms a belowground network, sequester nutrients and water for plants, and have much greater investment in plant health and environment than previously realized

Back to the roots: standardizing root length density terminology

The number of studies investigating root length has increased, particularly in the context of root length measurements observed through windows such as minirhizotrons and rhizoboxes. However, there are currently two obstacles constraining their broader utility: (1) the absence of standardized terminology or units for root length data, and (2) the translation from two-dimensional (2D) to three-dimensional (3D) data. Here, we delineate the fundamental disparities between root length measurements obtained from observation windows and via volumetric soil sampling and propose the adoption of more precise terminology to distinguish 2D planar (pRLD) from 3D volumetric (vRLD) root length density measurements. This differentiation should be accompanied with the use of standardized units and should not endeavour to make blanket conversions between dimensions unless this is supported by specific calibration data.
