- Regulation of DELLA rice protein interactors and their influence on plant developmentPublication . Fernandes, Telma; Abreu, Isabel"DELLA proteins play a pivotal role as key repressors in the gibberellin (GA) signalling pathway. The GA signal perception by the receptor GID1 initiates the formation of the GA-GID1-DELLA complex, leading to DELLA polyubiquitination and subsequent degradation. In the absence of GA, DELLA proteins exert their inhibitory effect on GA-mediated plant growth. Beyond their direct involvement in GA signalling, DELLA proteins act as central players in cellular responses, serving as transcriptional hubs through interactions with transcription factors and transcriptional regulators."
- Agronomic, Physiological, and Proteomic Characterization of Three Improved Varieties of Maize (Zea mays L.)Publication . Miquitaio, Dizimalta"Maize is the most important food crop in Mozambique. However, maize production is low and is cyclically impaired due to abiotic stresses such as recurrent droughts (particularly in the arid and semi-arid areas), soil infertility, floods, and cyclones events. Biotic stresses, such as pests and diseases, also affect food production. Altogether, these constraints lead to food insecurity and the need for humanitarian food aid from local and international communities. (...)"
- Unveiling the regulatory mechanisms behind SUMOylation to improve rice abiotic stress responsePublication . Rosa, Margarida T. Gomes"Climate change is one of the biggest concerns worldwide due to its effect on many physical and biological systems. Intense episodes of drought, heat, cold, and high salinity are becoming more frequent, compromising crop productivity. Thus, it is crucial to equip the plants with tools that will allow them to grow in such erratic/sub-optimal climate conditions. In order to achieve these biotechnological improvements, it is of utmost importance to understand the molecular mechanisms governing stress tolerance in crops, such as rice.(...)"
- Insights into the rice response to abiotic stress:Publication . Gonçalves, Nuno M."Abiotic stress is one of the biggest threats to food security worldwide, enhanced by a changing global climate and the alarming gap in crop productivity to face population growth. Rice (Oryza sativa) is one of the top staple food crops worldwide, along with wheat and maize, and is also one of the most susceptible monocots to abiotic stress, such as salinity, with moderate stress leading to up to 90% production losses."
