Special Issue Information

Dear colleagues,

The idea to release a Special issue called “Plant Plasticity” came to my mind by chance when I found on the peduncle of my phalaenopsis at home, instead of a flower, the formation of a “baby” or keiki, a clone of a mother plant, the development of which begins with the formation of leaves. In vitro morphogenic plasticity is a common phenomenon for me since I have worked with plant cell cultures for many years, but this observation of in vivo morphogenic plasticity prompted me to think generally about what, in fact, gives us the world of “phenes” – the world that lies beyond the genotype. Strictly speaking, it is thanks to their phenotypic plasticity that plants exist on the earth. Phenotypic plasticity gives them the opportunity to adapt to the plethora of biotic and abiotic stressors. Plasticity compensates for the main disadvantage of plants – the inability to move and hide from danger. Phenotypic plasticity is not only the appearance of new morphotypes in one genotype – it may have no visible morphological manifestation, but it can change the anatomy, biochemistry, and physiology of a plant. And all this the result of the interaction between the genotype and the environment! In our century, the study of plant phenotypic plasticity and its regulation, I think, will be the main topic of plant biology. The knowledge of how phenotypic plasticity is regulated in wild and cultivated plants will determine the ability of breeders to obtain stable yields in changing climates. Plant plasticity is a real challenge of the time and can include many subtopics.

This Special Issue of Plants will focus on different aspects of environmentally induced plant plasticity and the mechanisms underlying it.

The subtopics discussed will be the following (however, this list might be expanded):

  • The contribution of epigenetic factors in plant plasticity
  • Genetic control of phenotypic plasticity
  • Physiological plasticity
  • Developmental plasticity
  • Stress adaptive plasticity
  • Cell plasticity and differentiation
  • Plasticity in morphogenetic expression in plants and tissue cultures
  • Biochemical plasticity of plants and plant cell cultures
  • The impact of plant–microbe interactions on plant phenotypic plasticity and fitness

The Effect of Leaf Plasticity on the Isolation of Apoplastic Fluid from Leaves of Tartary Buckwheat Plants Grown In Vivo and In Vitro

Vacuum infiltration–centrifugation (VIC) is the most reproducible technique for the isolation of apoplast washing fluid (AWF) from leaves, but its effectiveness depends on the infiltration–centrifugation conditions and the anatomical and physiological peculiarities of leaves. This study aimed to elaborate an optimal procedure for AWF isolation from the leaves of Tartary buckwheat grown in in vivo and in vitro conditions and reveal the leaf anatomical and physiological traits that could contribute to the effectiveness of AWF isolation. Here, it was demonstrated that leaves of buckwheat plants grown in vitro could be easier infiltrated, were less sensitive to higher forces of centrifugation (900× g and 1500× g), and produced more AWF yield and apoplastic protein content than in vivo leaves at the same forces of centrifugation (600× g and 900× g). The extensive study of the morphological, anatomical, and ultrastructural characteristics of buckwheat leaves grown in different conditions revealed that in vitro leaves exhibited significant plasticity in a number of interconnected morphological, anatomical, and physiological features, generally driven by high RH and low lighting; some of them, such as the reduced thickness and increased permeability of the cuticle of the epidermal cells, large intercellular spaces, increase in the size of stomata and in the area of stomatal pores, higher stomata index, drop in density, and area of calcium oxalate druses, are beneficial to the effectiveness of VIC. The size of stomata pores, which were almost twice as large in in vitro leaves as those in in vivo ones, was the main factor contributing to the isolation of AWF free of chlorophyll contamination. The opening of stomata pores by artificially created humid conditions reduced damage to the in vivo leaves and improved the VIC of them. For Fagopyrum species, this is the first study to develop a VIC technique for AWF isolation from leaves. Full article

Leaves are essential plant organs with numerous variations in shape and size. The leaf size is generally smaller in plants that thrive in areas of higher elevation and lower annual mean temperature. The Qinghai–Tibetan Plateau is situated at an altitude of >4000 m with relatively low annual average temperatures. Most plant species found on the Qinghai–Tibetan Plateau have small leaves, with Rheum tanguticum Maxim. ex Balf. being an exception. Here, we show that the large leaves of R. tanguticum with a unique three-dimensional (3D) shape are potentially an ideal solution for thermoregulation with little energy consumption. With the increase in age, the shape of R. tanguticum leaves changed from a small oval plane to a large palmatipartite 3D shape. Therefore, R. tanguticum is a highly heteroblastic species. The leaf shape change during the transition from the juvenile to the adult phase of the development in R. tanguticum is a striking example of the manifestation of plant phenotypic plasticity. The temperature variation in different parts of the leaf was a distinct character of leaves of over-5-year-old plants. The temperature of single-plane leaves under strong solar radiation could accumulate heat rapidly and resulted in temperatures much higher than the ambient temperature. However, leaves of over-5-year-old plants could lower leaf temperature by avoiding direct exposure to solar radiation and promoting local airflow to prevent serious tissue damage by sunburn. Furthermore, the net photosynthesis rate was correlated with the heterogeneity of the leaf surface temperature. Our results demonstrate that the robust 3D shape of the leaf is a strategy that R. tanguticum has developed evolutionarily to adapt to the strong solar radiation and low temperature on the Qinghai–Tibetan Plateau.
