“…In contrast, in the more rapidly growing M. deliciosa , many mitoses are found in the growing zone and rhizoderm, including oblique divisions that lead to polycyte branching. According to our data, mitoses in M. deliciosa occurred at a considerable distance and the growth pattern may be intermittent (Eskov et al, 2016 ). In addition, for some aerial roots with negative geotropism, we described the reduction of the meristem (Eskov et al, 2017 ).…”

“…In M. deliciosa roots, the number of polycytes increases with increasing root thickness. It is also assumed that there is a gliding (intrusive) growth in polycytes when proliferating cells and new cell rows can invade intercellular spaces (Eskov et al, 2016 ). If there exists the gliding type of growth in polycytes, then this is a rather unexpected example of its manifestation because it is traditionally believed that it is peculiar to individual cells: cambial initials, primary and secondary fibers, tracheids, trichosclereids, and some other cells (Snegireva et al, 2010 ).…”

“…We hypothesized a fundamentally different structure and nature of growth in aerial roots because these do not experience substrate root-soil resistance (Eskov et al, 2016 ). Even at the dawn of experimental biology, aerial root growth was observed to be different from that of the substrate roots (Went, 1895 ; Linsbauer, 1907 ; Blaauw, 1912 ).…”

Cellular Growth in Aerial Roots Differs From That in Typical Substrate Roots

Background and AimsIn the roots of most vascular plants, the growth zone is small, the meristem and the elongation zone are sharply separated, and only meristematic cells divide. This statement is based almost entirely on studies with soil-rooted plants. Whether aerial roots of structurally dependent (=epiphytic/hemiepiphytic) species differ is virtually unexplored.MethodsGrowth of aerial roots in 20 structurally dependent plant species from eight families was studied ex situ. In 12 species, we studied the anatomical structure and distribution of cortex cell lengths and rhizoderm in the growth zone.Key ResultsAll the studied aerial roots had an open apical meristem, and mitoses were not restricted to the meristem. In contrast to belowground roots, relative growth rate did not strongly increase upon transition to the elongation zone, while elongating growth was often prolonged. Still, the relative growth rate was lower than in belowground roots in soil, and in different species, it did not change considerably compared to each other.ConclusionsA distinct elongation zone with rapid cell growth was missing in the studied aerial roots. Rather, there was a growth zone in which division, growth, and differentiation co-occurred. We observed a generally low relative growth rate in aerial roots and a surprisingly similar initial growth pattern in spite of the diversity in taxonomy and ecology, which resembled initial cellular growth in leaves, stems, and fleshy dicotyledonous fruit.

Here we report on a pilot study of the Living Root Bridges (LRBs) in the Indian State Meghalaya, which are grown with aerial roots of Ficus elastica , a facultative hemiepiphyte developing abundant aerial roots. Locals use these aerial roots to build living bridges, which strengthen themselves over time due to adaptive secondary growth and their capacity to form a mechanically stable structure via inosculations. An extensive inventory of LRBs in Meghalaya including data of location, altitude, approximate age and bridge length was performed in field studies. Root morphology was characterised by measurements of cross-sectional area and shape-related parameters and analysed in relation to the orientation of the roots. LRBs are found to occur mainly in the mountainous limestone rainforests where F. elastica may be native or traditionally cultivated. They cover an altitude range of 57–1211 m a.m.s.l. and display a length of 2 to 52.7 m. Some bridges are several hundreds of years old. Horizontally and vertically trained roots differ significantly in shape and cross-sectional area when approximately even-aged roots are compared. The results are discussed from an interdisciplinary perspective, considering the adaptive traits in the natural life cycle of F. elastica and possible applications in living architecture (Baubotanik).
