“…In A. thaliana , the stem (initial) cells located around the QC ( Dolan et al, 1993 ) give rise to all tissue types ( Figure 2 ). While cell cycle duration in the transit-amplifying domain in young A. thaliana seedlings, irrespective of accession, is on average 16.6 h ( Zhukovskaya et al, 2018 ), proximal stem cells divide on average every 58.6 h ( Rahni and Birnbaum, 2019 ).…”

In multicellular organisms, tissue generation, maintenance, and homeostasis depend on stem cells. Cellular metabolic status is an essential component of different differentiated states, from stem to fully differentiated cells. Threonine (Thr) metabolism has emerged as a critical factor required to maintain pluripotent/multipotent stem cells in both plants and animals. Thus, both kingdoms conserved or converged upon this fundamental feature of stem cell function. Here, we examine similarities and differences in Thr metabolism-dependent mechanisms supporting stem cell maintenance in these two kingdoms. We then consider common features of Thr metabolism in stem cell maintenance and predict and speculate that some knowledge about Thr metabolism and its role in stem cell function in one kingdom may apply to the other. Finally, we outline future research directions to explore these hypotheses.

“…In V. faba , P. sativum , Z. mays , P. vulgaris ( MacLeod and Thompson, 1979 ), and Arabidopsis ( Dubrovsky et al, 2001 ), the Td from early to later stages of LRP development increases from 8.2, 2.9, 4.5, 6.9, and 2.7 h to 14.16, 9.96, 17.65, 11.4, and 4.9 h, respectively. For Arabidopsis , the average Td in LRP cells is 7.1 h ( von Wangenheim et al, 2016 ), about half the average cell cycle duration observed in the primary-root apical meristem (reviewed in Zhukovskaya et al, 2018 ). Therefore, an overall short cell cycle and a gradual increase in cell cycle duration over time seems to be a general tendency.…”

Morphogenetic processes are the basis of new organ formation. Lateral roots (LRs) are the building blocks of the root system. After LR initiation and before LR emergence, a new lateral root primordium (LRP) forms. During this period, the organization and functionality of the prospective LR is defined. Thus, proper LRP morphogenesis is a decisive process during root system formation. Most current studies on LRP morphogenesis have been performed in the model species Arabidopsis thaliana; little is known about this process in other angiosperms. To understand LRP morphogenesis from a wider perspective, we review both contemporary and earlier studies. The latter are largely forgotten, and we attempted to integrate them into present-day research. In particular, we consider in detail the participation of parent root tissue in LRP formation, cell proliferation and timing during LRP morphogenesis, and the hormonal and genetic regulation of LRP morphogenesis. Cell type identity acquisition and new stem cell establishement during LRP morphogenesis are also considered. Within each of these facets, unanswered or poorly understood questions are identified to help define future research in the field. Finally, we discuss emerging research avenues and new technologies that could be used to answer the remaining questions in studies of LRP morphogenesis.

“…This aspect of Peter's work is represented in the SIAB by Zhukovskaya et al [66] Information on cell cycle duration (T) in the root apical meristem illuminates growth, development, and evolution of that plant organ. Obtaining estimates of that parameter are therefore important.…”

“…However, and although classical, that radioactive method is both laborious and time-consuming. In order to speed-up ascertainment of T, Zhukovskaya et al [66] present a global analysis of 73 angiosperm species using the RCP method, and compare the derived T values with those from the 3 H-thymidine method. They find that, in most species examined, T values obtained by both methods were nearly identical, and conclude that the RCP method enables cell cycle duration in the root apical meristem to be both rapidly and accurately determined.…”

Dr Peter Barlow, who died in 2017, was one of the most respected botanists and biologists of the latter half of the 20th Century. His interests covered a wide range of plant biological topics, e.g. root growth and development, plant cytoskeleton, effects of gravity, plant intelligence, pattern formation, and evolution of eukaryotic cells. Here we consider Peter’s numerous contributions to the: elucidation of plant patterns; understanding of root biology; role of the plant cytoskeleton in growth and development; influence of the Moon on terrestrial vegetation; Cell Body concept; and plant neurobiology. In so doing we attempt not only to provide an overview of Peter’s important work in many areas of plant biology, but also to place that work in the context of recent advances in plant and biological sciences.
