Summary

Plant-environment interactions are important determinants of agroecosystem performance. Unraveling the intricacy of these interconnections is a big scientific problem, especially for optimizing agroecosystem systems. We highlight recent advances and new techniques in this special issue that contribute to the knowledge of the interactions between crops and their environment (biotic and abiotic factors, management practices, climate change, and so on) in order to improve crop yield and quality, soil sustainability, and water quality. Plant physiology, metabolism, and soil fertility are all likely to be impacted by climate change. Plant growth, fertility, and production are all hampered as a result of this. To ensure the long-term viability of ecosystems, we must improve our understanding of molecules that drive important processes and may play a role in plant stress resilience mechanisms.

  • Transcriptome Analysis via RNA Sequencing Reveals the Molecular Mechanisms Underlying the Hedera helix Response to High Temperature
  • Abstract Hedera helix is an evergreen ornamental plant that is resistant to cool but not high temperature and deserves to be further researched for improving its adaptability to heat stress. Two Hedera helix cultivars, heat-tolerant (HT) ‘Jessica’ and heat-sensitive (HS) ‘Shamrock’, were used for differences analyses of transcriptome. We detected 6179 differentially expressed genes (DEGs) and 5992 DEGs in ‘Jessica’ and ‘Shamrock’ to heat stress, respectively. Among these, 1983 upregulated DEGs and 1400 downregulated DEGs were shared between both varieties, resulting in enhancement of various pathways such as biosynthesis of secondary metabolites, glyoxylate dicarboxylate metabolism, and protein processing in endoplasmic reticulum… More

  • Predicted Functional Shifts Due to Type of Soil Microbiome and Watering of Two Wild Plants in Western Region of Saudi Arabia
  • Abstract The present study aimed to predict differential enrichment of pathways and compounds in the rhizosphere microbiomes of the two wild plants (Abutilon fruticosum and Nitrosalsola vermiculata) and to predict functional shifts in microbiomes due to water. Amplicon sequencing of 16S rRNA region V3–V4 was done and gene-based microbial compositions were enrolled in PICRUSt to predict enriched pathways and compounds. The results indicated that “ABC transporters” and “Quorum sensing” pathways are among the highest enriched pathways in rhizosphere microbiomes of the two wild plants compared with those of the bulk soil microbiomes. The highest enriched compounds in soil microbiomes of the… More

  • Tea Plantation Frost Damage Early Warning Using a Two-Fold Method for Temperature Prediction
  • Abstract As the source and main producing area of tea in the world, China has formed unique tea culture, and achieved remarkable economic benefits. However, frequent meteorological disasters, particularly low temperature frost damage in late spring has seriously threatened the growth status of tea trees and caused quality and yield reduction of tea industry. Thus, timely and accurate early warning of frost damage occurrence in specific tea garden is very important for tea plantation management and economic values. Aiming at the problems existing in current meteorological disaster forecasting methods, such as difficulty in obtaining massive meteorological data, large amount of calculation… More

  • Changes in Florets’ Vertical Direction within Inflorescence Affects Pollinator Behavior, and Fitness in Trifolium repens
  • Abstract Ecological interactions between flowers and pollinators greatly affect the reproductive success. To facilitate these interactions, many flowers are known to display their attractive qualities, such as scent emission, flower rewards and floral vertical direction, in a rhythmic fashion. However, less is known about how plants regulate the relationship between these flower traits to adapt to pollinator visiting behavior and increase reproduction success. Here we investigated the adaptive significance of the flower bending from erect to downward in Trifolium repens. We observed the flowering dynamic characteristics (changes of vertical direction of florets, flowering number, pollen grain numbers, pollen viability and stigma… More
