“…Ethylene signaling stands as the sole example of a phytohormone with a clear signaling cascade reported to be functionally conserved between land plants and Zygnematophyceae, although its biosynthetic pathway may not need to be necessarily conserved 54,55 . Exogenous ethylene treatment of the zygnematophyceaen alga Spirogyra induces growth phenotypes and the differential expression of stress- and photosynthesis-associated genes identified in land plants 56 .…”

The earliest land plants faced a significant challenge in adapting to environmental stressors. Stress on land is unique in its dynamics, entailing swift and drastic changes in light and temperature. While we know that land plants share with their closest streptophyte algal relatives key components of the genetic makeup for dynamic stress responses, their concerted action is little understood. Here, we combined time-course stress profiling using photophysiology, transcriptomics on 2.7 Tbp of data, and metabolite profiling analyses on more than 270 distinct samples, to study stress kinetics across three 600-million-year-divergent streptophytes. Through co-expression analysis and Granger causal inference we predict a gene regulatory network that retraces a web of ancient signal convergence at ethylene signaling components, osmosensors, and chains of major kinases. These kinase hubs already integrated diverse environmental inputs since before the dawn of plants on land.

“…Ethylene is an important regulator of plant development, and its actions were described a relatively long time ago [ 149 , 150 , 151 ]. Ethylene can be considered a typical stress hormone [ 152 ]; therefore, it has a dual role during plant morphogenesis in vitro. Ethylene should get special attention in PTC since plant growth is relatively small in isolated volumes with lower air exchange rates than in natural conditions, a system with a high risk of ethylene accumulation.…”

Precise knowledge of all aspects controlling plant tissue culture and in vitro plant regeneration is crucial for plant biotechnologists and their correlated industry, as there is increasing demand for this scientific knowledge, resulting in more productive and resilient plants in the field. However, the development and application of cell and tissue culture techniques are usually based on empirical studies, although some data-driven models are available. Overall, the success of plant tissue culture is dependent on several factors such as available nutrients, endogenous auxin synthesis, organic compounds, and environment conditions. In this review, the most important aspects are described one by one, with some practical recommendations based on basic research in plant physiology and sharing our practical experience from over 20 years of research in this field. The main aim is to help new plant biotechnologists and increase the impact of the plant tissue culture industry worldwide.

“…Ethylene is known to spontaneously accumulate in the plant body because of the limitation of gas exchange under submerged conditions (Davis and McKetta 1960 ), and ABA is involved in the water stress response (Kuromori et al 2018 ). Moreover, an ethylene response has been observed in a wide range of angiosperms (Van de Poel and de Vries 2023 ), and the ABA pathway is conserved in green plant lineages (Takezawa et al 2011 ). Therefore, it seems reasonable that these hormones are utilized to trigger submergence responses such as heterophylly.…”

Leaf form can vary at different levels, such as inter/intraspecies, and diverse leaf shapes reflect their remarkable ability to adapt to various environmental conditions. Over the past two decades, considerable progress has been made in unraveling the molecular mechanisms underlying leaf form diversity, particularly the regulatory mechanisms of leaf complexity. However, the mechanisms identified thus far are only part of the entire process, and numerous questions remain unanswered. This review aims to provide an overview of the current understanding of the molecular mechanisms driving leaf form diversity while highlighting the existing gaps in our knowledge. By focusing on the unanswered questions, this review aims to shed light on areas that require further research, ultimately fostering a more comprehensive understanding of leaf form diversity.
