The term gender scissor describes the distribution of men and women throughout their scientific career: while girls represent more than a half of the University students, the percentage of women in science markedly decreases beyond the PhD. This trend has been reported in different European Union member states including France. In this country, female scientists […]

About Michela Osnato
I completed my studies at the University of Milan (ITALY), first with a M.S. in Plant Biotechnology and then with a PhD in Plant Biology and crop productivity.
The plasticity of plant development has always fascinated me. For this reason, I decided to investigate Gene Regulatory Networks underlying the development of vegetative and reproductive organs in model species and cereal crops. Recently, I have focused my research on the crosstalk between phytohormones and regulatory genes in plant adaptation to climate change (e.g. elevated ambient temperature, water limitation, soil salinity). The long-term goal is to use novel findings to obtain plant varieties characterized by improved climate resilience.
Despite thinking of myself as a motivated biotechnologist, my interest for public engagement progressively swayed me towards the participation in different outreach activities. Among others, I developed my own science communication project and disseminated science using Social networks (@secretlifeofaplantbiologist).
I am currently a member of the Plantae fellow program and regularly contribute to Science News stories with summaries and graphical abstracts.

According to FAO, only a hundred out of several thousands edible plants contribute to the global food system. Specifically, twelve species dominate food production worldwide; more than a half of our daily calorie intake comes from four seed crops (maize, soybean, rice and wheat). Although the agricultural relevance of a crop largely associates with its […]
In Arabidopsis, flowering is promoted by the activation of the florigen FT in response to long days and by the accumulation of the phytohormone GA under short days (SD). Despite the extensive knowledge of regulatory networks involving FT, the molecular mechanism controlled by GA is still unresolved. Fukazawa and coworkers previously identified GAI-ASSOCIATED FACTOR1 (GAF1), […]
Gamma-aminobutyric acid (GABA) is a non-protein amino acid produced by animals and plants, but is its function conserved across kingdoms? In mammals, GABA acts as chemical messenger in the central nervous system by inhibiting neurotransmission. In plants, GABA accumulates in response to stress but its role in cellular communication is still unresolved. In this study, […]
One of the most fascinating challenges in developmental biology is to understand how a few stem cells hidden in a microscopic region of the shoot apex give origin to all aerial parts of the plant. Technological advances such as single-cell RNA-sequencing (scRNA-seq) are enabling the comprehensive analysis of heterogeneous cell populations with unprecedent resolution. Zhang […]
In maize (Zea mays), loss of function mutations in genes involved in starch biosynthesis characterize sweet corn varieties that have increased sugar content in the kernel. Specifically, lines carrying the shrunken2 (sh2) allele revolutionized the corn industry in Northern America in the last 50 years thanks to improved quality traits and shelf life. Besides the […]
Gibberellin (GA) controls multiple developmental processes throughout the plant life cycle, from seed germination to flowering. In Arabidopsis, GA also regulates division of meristematic cells at the tip of the root and cell elongation in the growing zone. Despite its importance, little is known about the events that generate the GA gradient that drives growth […]
Jasmonate (JA) coordinates plant development and response to a wide range of biotic and abiotic stresses. JA production is stimulated by wounding, which damages cell walls, and increased in plants carrying mutations in cellulose biosynthetic genes. Nevertheless, the intracellular events connecting mechanical stress and JA production largely remain unresolved. In a forward genetic screen aimed […]
Angiosperms synchronize the floral transition with optimal internal and external conditions such as daylength to maximize reproductive success. Despite the wealth of knowledge on the molecular mechanisms controlling flowering time, little is known about the cellular events that occur as the vegetative meristem converts into a reproductive meristem. Here, Kinoshita and coworkers combined confocal microscopy […]
