Article Synopsis
- The study utilized a novel experimental design to identify key biological pathways affected by nitrogen deficiency in an evergreen tree crop, highlighting processes like lignin biosynthesis and defense responses.
- The research found significant upregulation of the MAPK pathway and ATP-binding cassette transporters, with a greater focus on calcium signaling over hormone signaling, particularly involving auxin and abscisic acid.
- A total of 45 transcription factors were increased under nitrogen deficiency, indicating a shared regulatory role in both nitrogen and pathogen responses, especially in relation to flavanoids and cell wall integrity.
Article Synopsis
- Early detection of stress in tea plants is essential for improving breeding strategies and understanding plant genetics.
- Hyperspectral technology enables rapid assessment of plant health through specific reflectance indices, but these must be validated for each crop.
- Out of 31 vegetation indices studied, several were effective in distinguishing between stress-tolerant and susceptible tea plants, particularly those that utilize near-infrared reflectance, which aids in managing tea germplasm under abiotic stress conditions.
Introduction: Low temperatures and drought are two main environmental constraints reducing the yield and geographical distribution of horticultural crops worldwide. Understanding the genetic crosstalk between stress responses has potential importance for crop improvement.
Methods: In this study, Illumina RNA-seq and Pac-Bio genome resequencing were used to annotate genes and analyze transcriptome dynamics in tea plants under long-term cold, freezing, and drought.
Citrus collections from extreme growing regions can be an important source of tolerant germplasms for the breeding of cold-tolerant varieties. However, the efficient utilization of these germplasms requires their genetic background information. Thus, efficient marker systems are necessary for the characterization and identification of valuable accessions.

Calcium participates in most of cellular signaling processes, and its important role in stress detection and triggering a response has been shown in many crops.
