Climate change severely affects plant growth and jeopardizes yields of essential seed crops such as rice. Still, the mechanisms underlying the synergistic regulation of abiotic stress response and important agronomic traits remain poorly understood. Dong et al. cloned and characterized a major QTL in rice, named Grain Size and Abiotic stress tolerance 1 (GSA1) after […]

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.

Over the past decade, Next Generation Sequencing (NGS) has been used for de novo assembly of crop genomes (i.e., tomato, potato) under the motto “If it tastes good, let’s sequence it”. By contrast, the One Thousand Plant (1KP) Initiative set out to obtain transcriptomic data of phylogenetically diverse green plant species without any apparent economic […]
Biofuels can be obtained from bioenergy crops such as sorghum, maize and sugarcane. However, the production of bioethanol is still more expensive than that of petroleum. Given the importance of replacing conventional fossil fuels with renewable liquid fuels, the biorefinery system should be improved to reach the Minimum Ethanol Selling Price (MESP) of $2.50/galllon. One […]
Flower development has always been a fascinating field of research in plant biology. While molecular studies in the past focused on regulatory genes involved in the formation of floral organs in model species, current investigations are addressing the genetic determinants underlying the huge variety of flower. Recently, the genetic basis of the double flower trait […]
Among the myriad small interfering RNAs, 21- and 24-nucleotides siRNAs control plant development and immunity through mRNA cleavage and RNA-directed DNA methylation, respectively. Still, the regulation and biological function of 22-nt siRNAs remain unresolved. In this report, Wu and coworkers investigated the massive accumulation of 22-nt siRNAs in plants with mutations in DICER-like 4 (DCL4) […]
Thale cress (Arabidopsis thaliana) has been the absolute star of plant science research for more than 40 years, being the ideal model organism for its ease of handling and transferable knowledge to crops. In this review, Cesarino and coworkers explain how advances in “omics” technologies, together with improvements in molecular techniques and genetic transformation, have […]
Archeological remains and genetic analyses of ancient DNA have revealed that the loss of seed dispersal marks the onset of domestication for sexually reproduced crops such as cereal, legume and oils seed crops, for which annual cultivation is based on sowing seeds. In contrast, less is known about the domestication of vegetatively propagating plants including […]
To date, archeobotanical and genetic studies indicated four centers of plant cultivation in the early Holocene: China and the Near East in the Old World, and southwestern Mexico and northwestern South America in the New World. Recent research of Lombardo et al. revealed that Llanos de Moxos (Bolivia) in southwestern Amazonia could also be a […]
Plants evolved molecular mechanisms to integrate seasonal changes with developmental programs. For example, warmer temperatures and increasing day-length mark the transition from winter to spring, and trigger flowering. Now, the synchronisation of ambient temperature and photoperiod is perturbed by global warming, which causes growth alteration in different plant species. Nevertheless, plants are able to modify […]
