Накратко на български

Механизмите за формиране на плодовете при растенията се изследват чрез сравнение между сърцевидните плодове на Capsella rubella и тези на Arabidopsis. Разбирането на тези процеси помага да се разбере как еволюира разнообразието от форми и как се координира растежът на тъканите.

Shaping fruit morphogenesis of floWEring plants by ElucidaTing HEART-shaped fruit development in Capsella rubella

The flowering plants (angiosperms) evolved over 100 million years ago and quickly colonized every habitable corner of the planet. Such success hinges largely on their extraordinary reproduction system. Among all, fruit development is an essential process to protect and nurture developing seeds and eventually promote successful dissemination of viable progeny into habitable environmental niches. The Brassicaceae family comprises approximately 3,700 species including the model plant Arabidopsis thaliana and several agriculturally and economically important crops from the Brassica species, such as B. oleracea (broccoli) and B. napus(canola). Although the overall composition and organization of fruit tissues are highly conserved among members of the Brassicaceae family, massive variation is observed in fruit shape, from simple spheres and cylinders to more complex curved forms. However, the mechanism underlying such diversity is still poorly understood. In many cases it is not immediately evident what advantages the different shapes provide for fitness and dispersal. It is also unclear how such variation in form can evolve when coordination of tissue growth and specification is of pivotal importance for timely development and seed release. To investigate factors controlling fruit shape, Capsella rubella is emerging as a good comparative model against Arabidopsis due to the distinct heart-shaped fruit shape and its close evolutionary proximity. In summary, my SWEETHEART project aimed to address this knowledge gap by answering several important questions: (1) Can I find other factors exist that control fruit shape in Capsella? (2) How is the well-known protein ANGUSTIFOLIA (AN) controlling fruit development in Arabidopsis and Capsella? (3) To which extent is the AN/FUL/IND module controlling fruit shape in Arabidopsis and Capsella? Answering these questions will contribute to our understanding of plant organ morphogenesis in general and help to explain fruit-shape diversity in Brassicaceae in particular. Importantly, oilseed rape is the 2nd most important oilseed crop worldwide and the study of fruit development will provide insight for the crop breeding industry in developing varieties with improved performance in terms of yield.

Цел на проекта

The flowering plants (angiosperms) evolved over 100 million years ago and quickly colonized every habitable corner of the planet. Such success hinges largely on the formation of fruits that protect and nurture the developing seeds. Moreover, a massive range of diversity in fruit shape arose during a relatively short time, which allowed for the development of ingenious ways of fertilisation as well as strategies for efficient seed dispersal. The Brassicaceae family contains a wealth of diversity in fruit morphologies and includes some of our genetically best characterised model plants and important crop species. Thus, the Brassicaceae family provides an ideal group of plants to study how specific shapes are established. Although many genes controlling fruit patterning in the model plant Arabidopsis thaliana have been identified, processes leading to specific fruit morphologies are still poorly understood. To unravel these processes, I will study fruit shape using the heart-shaped fruits from Capsella rubella as a model system to unravel molecular mechanisms by which growth is oriented and coordinated to generate this shape. I will exploit a panel of Capsella fruit-shape mutants including the heartless (htl) mutant, which encodes a putative orthologue of the Arabidopsis ANGUSTIFOLIA (AN) protein. To investigate the molecular mechanism by which the HTL/AN protein controls fruit shape formation in Capsella, I will characterize the interacting proteins of HTL by immunoprecipitation followed by mass spectrometry analysis. Novel genetic regulators of fruit shape will be identified and I will study their role in fruit development using biochemical, molecular and genetic analyses. Beyond the elucidation of how the genetic network is established to control anisotropic growth during development, the work described in this proposal will provide new directions for shaping seed and fruit crops for enhanced performance.
