Angiosperms differentiate from the meristem to form flower buds, to the development of flowers and flowering is a complex process. To ensure the successful reproduction of plants, multiple molecular pathways regulated by genetic and environmental factors are involved in this process. The extended life cycle of perennial woody plants such as coffee, such as a two-year cycle, continuous flowering, and winter bud dormancy, is an adaptation mechanism established by plants for successful reproduction in a changeable environment. The driving force of coffee flowering, especially during its reproductive growth stage, incorporates a variety of stimulating factors to induce changes in its physiological form.
In 2021, a team of Professor Antonio Chalfun-Junior of the Plant Physiology Laboratory of the Department of Biology of the Federal University of Lavras, Brazil, published anoverview of the endogenous and environmental factors related to the Coffeaarabica flowering at Beverage Plant Research Overview of the process.
This paper comprehensively discusses various factors directly or indirectly related to the various molecular pathways involved in the transformation of coffee reproductive meristem, flower development and flowering. In this paper, the authors propose to redefine some concepts related to coffee flowering, such as summarizing genes that may be involved in flowering pathways, reclassifying buds according to the position of buds on the nodes to avoid misunderstandings caused by uneven developmental stages, and discussing the development of coffee flower organ chakras in depth by comparing the differences between Arabidopsis thaliana and tomato ABC models. The authors also propose to solve problems such as the improvement of bud activity, the control of flowering time, the control of flowering synchronization (to promote more uniform fruit ripening), how to reduce the failure of breeding or early flowering, and increase the results through cooperation, so as to promote research on coffee breeding and production.
Figure The model of induction and coffee blossom development under environmental conditions proposed in this paper
This article explores the relationship between physiological and molecular pathways during coffee flowering, and will shed light on the evolution of other tropical perennials, especially those that flower out of sync, and rubiaceae.
