Special Issue Information

Dear Colleagues,

Human society requires ever-increasing and diversified food resources, and climate change and unadapted technologies are creating huge pressures on horticultural ecosystems for food production. The germplasm of a horticultural species is an essential genetic resource for identifying and selecting valuable attributes of tolerance to abiotic stressors. In recent decades, the investigation techniques of the physiological processes involved in increasing the tolerance of plants to stressors have reached levels of performance that are difficult to imagine, and their association with methods of molecular biology, breeding or applied biochemistry, have led to the achievement of remarkable findings in horticultural species. Additionally, huge advances have been made in the use of artificial intelligence, integrated sensor systems, information, analysis and communication technologies for the induction, detection and monitoring of abiotic parameters that can act as stressors of plants, with a determination of the impact on metabolic processes of productivity and the quality of crops.

However, there are still many unknowns regarding the complex functioning mechanisms of plants in a huge variety of ecosystems, either cultivated or spontaneous, each with specific characteristics. There are also many unsolved questions related to the multitude of structural and/or functional mechanisms for the adaptation of plants to their environments.

The germplasm sources of horticultural crops (vegetables, fruit or floricultural species, ornamental trees and shrubs, fungi, etc.) are real "gene banks", suppliers of valuable attributes of adaptations to stress, productivity, and quality, which must be further discovered, characterized, evaluated, protected and preserved to be used for improving the performance of cultivated species.

This Special Issue will highlight the importance of horticultural germplasm sources in improving tolerance characteristics to the multitude of environmental stressors (water, soil, air, climate, etc.) in cultivated species by analyzing biochemical, morphological, physiological and genetic parameters involved in reactions to stress and their influence on the bio-productivity, growth and development of plants.

Calmodulins (CAMs) and calmodulin-like proteins (CMLs) can participate in the regulation of various physiological processes via sensing and decoding Ca2+ signals. To reveal the characteristics of the CAM/CML family in Ginkgo biloba, a comprehensive analysis was performed at the genome-wide level. A total of 26 CAMs/CMLs, consisting of 5 GbCAMs and 21 GbCMLs, was identified on 11 out of 12 chromosomes in G. biloba. They displayed a certain degree of multiplicity in their sequences, albeit with conserved EF hands. Collinearity analysis suggested that tandem rather than segmental or whole-genome duplications were likely to play roles in the evolution of the Ginkgo CAM/CML family. Furthermore, GbCAMs/GbCMLs were grouped into higher, lower, and moderate expression in magnitude. The cis-acting regulatory elements involved in phytohormone-responsiveness within GbCAM/GbCML promotors may explain their varied expression profiles. The ectopic expression of a GbCML gene (Gb_30819) in transgenic Arabidopsis led to phenotypes with significantly shortened root length and seedling height, and decreased yields of both pods and seeds. Moreover, an electrophoresis mobility shift assay demonstrated the Ca2+-binding activity of Gb_30819 in vitro. Altogether, these results contribute to insights into the characteristics of the evolution and expression of GbCAMs/GbCMLs, as well as evidence for Ca2+-CAM/CML pathways functioning within the ancient gymnosperm G. biloba.
