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 […]

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.

Vilarrasa-Blasi and coworkers described their impressive work on a huge barcoded Chlamydomonas collection, in which they screened almost 60,000 insertion mutants grown under a wide range of environmental and chemical stress conditions. The authors assessed genotype-phenotype specificity for almost 80% of C. reinhardtii genes, represented by one or multiple allelic variants, and shed new light […]
Auxin shapes the plant body and drives the formation of lateral organs such as roots and ovules. In the current model, AUXIN RESPONSE FACTORs (ARFs) are transcription factors that regulate plant growth by activating signaling in an auxin dose-dependent manner, regulated by Aux/IAA proteins. Here, Cucinotta and coworkers demonstrate a new twist on this paradigm, […]
Global warming and intensive farming are increasing soil salinity, which is predicted to affect 30% of cultivated land by 2050. Salinity represents a major threat for agriculture as most crops drastically reduce their growth and productivity in saline environments. Understanding the strategies used by halophytes (salt-tolerant plants) and transferring them to glycophytes (salt-intolerant plants) could […]
The onset of reproductive development is tightly regulated in response to environmental cues as early and delayed flowering greatly affects seed production. In Arabidopsis, the timing of flower formation is controlled by members of the Phosphatidyl Ethanolamine-Binding Protein (PEBP) family: TERMINAL FLOWER 1 (TFL1) promotes inflorescence fate whereas FLOWERING LOCUS T (FT) promotes floral fate. […]
Cis-regulatory elements (CREs) are DNA sequences found near or within genic regions that drive proper gene expression in time and space. Thus, CREs play essential roles in the diversification of spatially distinct cell-types with specialized function in multicellular organisms. To identify CREs underlying the specification of different organs in the crop species Zea mays (maize), […]
Gene gain through duplication and gene loss through loss-of-function (LoF) mutations determine genetic variation underlying diversification and adaptive evolution. In this review, Xu and Guo highlight the importance of LoF mutations in the evolutionary success of several organisms as revealed by advancements in whole-genome sequencing. The authors focused on the genome-wide distribution of LoF variants […]
In Arabidopsis pistils, ovule primordia differentiate from the placenta – meristematic tissue within the two fused carpels – in parallel rows with a regular spacing of 2-4 cells. Since fruit growth and ovule formation determine the maximum number of seeds enclosed in a silique, these two processes should be tightly coordinated to ensure reproductive success. […]
Plants communicate with the environment through stomata (i.e., pores found on leaf surfaces) and regulate gas exchange depending on internal and external cues by optimizing stomata density. Still, how plants integrate metabolic and environmental signals remain to be determined. Here, Han and colleagues discovered that stomatal index in Arabidopsis leaves decreased under conditions associated with […]
