This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact

My idea of a theory in biology is quite different from the theoretical biology that is expressed as equations of observed or photographed phenomena. I have a simpler, more concrete conception. Not a mathematical description of what is seen, but an evolving model, a tool developed through bricolage, with mathematics perhaps, but also natural language: one that serves above all to understand the unseen; to guess, beneath the visible, the invisible dimensions of life forms, the underlying “logic”.

The fruit is an important plant structure. Not only does it provide a suitable environment for seeds to develop and serve as a vehicle for seed disposal, but it is also an indispensable part of the human diet. Despite its agronomic and nutritional value and centuries of intensive genetic selection, little is known about the molecular mechanism of its development or the evolution of its diverse forms. The last few years have witnessed a surge of investigations on the early stages of fruit development propelled by the advancement of high throughput sequencing technology, genome sequencing of fruit bearing species, and detailed molecular insights based on studies of model organisms. This research topic is focused on early stage fruit development that ranges from pre-fertilization patterning of the female ovary through post-fertilization fruit initiation and growth. Provided by the renowned experts in the field, these papers are intended to highlight recent progress and shed light on different aspects of fruit development from structure, function, to molecular genetics, and evolution.

Rakov Škocjan is a basin in a small karst plain comprising the Rak Valley and the small basin Podbojev Laz. Bedrock terraces in the basin slopes indicate flattening of the basin floor at the water table level at higher elevations and progressive basin development and transformation with surface water flow. Detailed studies of the surface and subsurface karst features in Rakov Škocjan made it possible to describe the basin’s evolution and its development in previous genetic stages. The study (‘Geomorphological Characteristics of Rakov Škocjan‘) based on detailed morphographic mapping, collection of morphometric data, speleological analyses, and granulometric analyses of loamy sediments. A synthesis of the findings shows that the basin’s genesis and development was much more complex than described in earlier literature. The basin was formed as a surface karst feature through several development stages in which the locations of springs and ponors had changed. Morphogenetic characteristics resulted in an exceptional variety of karst phenomena in a small area, although the basic water course in the broader regional sense did not significantly change. Kotlina Rakov Škocjan je poglobitev v manjši kraški uravnavi, sestavljena iz doline Raka in kotanje Podbojev laz. V pobočjih kotline so izoblikovane živoskalne uravnave, ki kažejo na uravnavanje dna kotline na višjih nadmorskih višinah, postopen razvoj in preoblikovanje s površinsko tekočo vodo. Podrobno so bile preučene površinske in podzemne kraške oblike, ki nakazujejo razvoj kotline v preteklih razvojnih fazah. Preučevanje je temeljilo na podrobnem morfografskem kartiranju območja, zajemu morfometričnih podatkov preučevanih oblik, speleoloških analizah jam in laboratorijskih analizah ilovnatega sedimenta. Sinteza nakazuje, da sta nastanek in razvoj kotline kompleksnejša, kot je bilo doslej predstavljeno v literaturi. Kotlina se je namreč kot površinska kraška oblika oblikovala v več fazah, v katerih so se lokacije izvirov in ponorov spreminjale. To je povzročilo izredno pestrost kraških pojavov na majhnem območju.

Plant architecture is a major determinant of the resource use efficiency of crops. The architecture of a plant shows ontogenetic structural changes which are modified by multiple environmental factors: Plant canopies are exposed to natural fluctuations in light quantity and the dynamically changing canopy architecture induces local variations in light quality. Changing temperature conditions or water availability during growth additionally affect plant architecture and thus crop productivity, because plants have various options to adapt their architecture to the available resources. Meeting the challenge of ensuring food security we must understand the plant’s mechanisms for integrating and responding to an orchestra of environmental factors. ‘Virtual plants’ describe plant architecture in silico. Virtual plants have the potential to help us understanding the complex feedback processes between canopy architecture, multiple environmental factors and crop productivity. As a research tool, they have become increasingly popular within the last decade due to their great power of realistically visualizing the plant’s architecture. This Research Topic highlights current research carried out on modeling plant architecture in changing environments.

How can we explain the fundamental paradox of living matter, which combines stability and robustness of form with constant internal dynamics? It is not only the genetic information contained in every cell, but also numerous stochastic biomolecular processes that are at work in morphogenesis. In addition, the shaping of an organism is driven by mechanical forces that operate within and between cells, across tissues and organs. The dynamics of morphogenesis is a self-organized process that emerges from biological control and physical constraints at all scales. Its study is currently bringing together a fast-growing interdisciplinary community that observes, analyses and models living organisms.

De nombreux organismes sont composés de parties répétées, identiques ou modifiées (segments de vers de terre, vertèbres, etc.). Ce mode d’organisation fait l’objet depuis la fin du XVIIIe siècle, de nombreuses interrogations de la part des biologistes : quelle est sa signification anatomique, comment se met-il en place lors de l’embryogenèse, que peut-on en déduire sur l’évolution des espèces, etc. ? Ce livre retrace l’histoire de ces questionnements, des théories et des concepts qu’ils ont suscités depuis deux siècles. Il montre que ce problème de la répétition des parties n’a cessé d’occuper une position centrale, au carrefour de plusieurs disciplines biologiques, et ce jusqu’à nos jours.
