Special Issue Information

Dear Colleagues,

Today, environmental stresses represent the main constraints for agriculture, affecting plant growth, physiology, and crop productivity worldwide.

Given the increasing challenges imposed by climate change, this Special Issue aims to provide insights that contribute to sustainable agriculture and global food security. This Special Issue will focus on crop responses related to plant resilience under actual and projected environmental constraints. We are open to all aspects of the responses and mechanisms of plant resilience to abiotic stresses (as are drought, flooding, extreme temperatures, salinity, nutrient deficiencies, high radiation, shade, UV radiation, ozone, etc.). Submissions addressing model species, major crops, and underutilized species relevant to local or global agriculture are all welcome. Contributions of physiological, biochemical, molecular and agronomical studies about crop responses to abiotic stresses will be welcomed. Integrative approaches combining omics, phenotyping, genome editing, and computational modeling to understand and improve crop resilience are also encouraged.

This Special Issue aims to bring together a collection of original research, reviews, and opinion articles that highlight recent advances obtained about genotype–phenotype association studies to select more resilient and/or productive varieties; metabolomics approaches to characterize biochemical responses and pathways of stress responses; architectural studies of ideotypes resilient to stress; molecular traceability studies to ensure crop yields and quality; and molecular and physiological responses under sustainable methods of agricultural production.

Coffea canephora cultivation areas in Brazil are frequently exposed to successive cycles of water deficit, triggering plant stress responses. In addition to water deficit, increased air temperature can act as a second stress factor. The recurrence of these stress factors may induce plant tolerance mechanisms, potentially mitigating future stress responses even of a different stress nature. We hypothesized that repeated cycles of water deficit can trigger tolerance mechanisms that make C. canephora leaves more resilient to supra-optimal temperatures. To test this hypothesis, young C. canephora plants were grown under non-limited water conditions for seven months (ΨmSoil > −20 kPa), after which they were subjected to two consecutive cycles of water deficit (ΨmSoil < −300 kPa), followed by rehydration. Two clones were used, ‘A1’ and ‘3V’, previously classified as drought sensitive and tolerant, respectively, considering the dynamics of physiological and architectural responses. After the second cycle, leaf discs were collected from completely expanded leaves formed during the two stress cycles and exposed to heat treatments (35 °C, 40 °C, 45 °C, 50 °C, and 55 °C) for 15 min in a water bath. Chlorophyll a fluorescence emission was then monitored, and the results were analyzed using OJIP transient kinetics and the JIPTest. High temperatures induced negative changes in both OJIP kinetics and JIPTest-derived parameters. A significant increase in F0 and a reduction in FM were observed mainly at 50 °C and 55 °C, due to changes in the stages of the OJIP curve. These changes impacted the “energy connectivity” and consequently the electron transport along the electron transfer chain (ETC), increasing energy dissipation, as confirmed by the JIPTest variables. Despite the high temperature impacts, previous water deficit induced heat tolerance in clone ‘A1’, while it increased sensitivity in clone ‘3V’. This study suggests that selecting drought-resistant varieties should consider their subsequent response to short high-temperature stress to avoid cross-sensitivity caused by selecting for a single environmental factor.
