Molecular Links between Flowering and Abiotic Stress Response: A Focus on Poaceae / D. Chirivì, C. Betti. - In: PLANTS. - ISSN 2223-7747. - 12:2(2023), pp. 331.1-331.16. [10.3390/plants12020331]
Abstract:
Extreme temperatures, drought, salinity and soil pollution are the most common types
of abiotic stresses crops can encounter in fields; these variations represent a general warning to
plant productivity and survival, being more harmful when in combination. Plant response to such
conditions involves the activation of several molecular mechanisms, starting from perception to
signaling, transcriptional reprogramming and protein modifications. This can influence the plant’s
life cycle and development to different extents. Flowering developmental transition is very sensitive
to environmental stresses, being critical to reproduction and to agricultural profitability for crops. The
Poacee family contains some of the most widespread domesticated plants, such as wheat, barley and
rice, which are commonly referred to as cereals and represent a primary food source. In cultivated
Poaceae, stress-induced modifications of flowering time and development cause important yield losses
by directly affecting seed production. At the molecular level, this reflects important changes in gene
expression and protein activity. Here, we present a comprehensive overview on the latest research
investigating the molecular pathways linking flowering control to osmotic and temperature extreme
conditions in agronomically relevant monocotyledons. This aims to provide hints for biotechnological
strategies that can ensure agricultural stability in ever-changing climatic conditions.
