Exogenous tryptophan enhances cold resistance of soybean seedlings by promoting melatonin biosynthesis

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(2)

Published: March 1, 2025

Given the global climate change, soybean production is highly susceptible to low temperature. Although tryptophan, synthesis precursors of melatonin and auxin, exhibited a positive effect in regulating plant growth, it still unclear whether tryptophan could improve tolerance temperature stress through endogenous synthesis. Therefore, on resistance two varieties seedlings (4°C) was evaluated, main regulation pathway verified with inhibitors. The results revealed that significantly inhibited growth soybean, while application exogenous enhanced antioxidant activity reduce content reactive oxygen species, including O2 - (11.3%) H2O2 (17.8%), effectively protected photosynthetic capacity leaves, involving net rate (22.94%), transpiration (15.31%), stomatal conductance (20.27%). And increased leaf area (16.63%), height (7.14%), root surface (24.37%), volume (22.92%) tip number (29.67%) at However, p-chlorophenylalanine eliminated tryptophan. In conclusion, mainly improved cold by promoting synthesis, which provided theoretical basis for enhance field production.

Harnessing de novo transcriptome sequencing to identify and characterize genes regulating carbohydrate biosynthesis pathways in Salvia guaranitica L.

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: Sept. 26, 2024

Introduction Carbohydrate compounds serve multifaceted roles, from energy sources to stress protectants, found across diverse organisms including bacteria, fungi, and plants. Despite this broad importance, the molecular genetic framework underlying carbohydrate biosynthesis pathways, such as starch, sucrose, glycolysis/gluconeogenesis in Salvia guaranitica , remains largely unexplored. Methods In study, Illumina-HiSeq 2500 platform was used sequence transcripts of S. leaves, generating approximately 8.2 Gb raw data. After filtering removing adapter sequences, 38 million reads comprising 210 high-quality nucleotide bases were obtained. De novo assembly resulted 75,100 unigenes, which annotated establish a comprehensive database for investigating glycolysis biosynthesis. Functional analyses glucose-6-phosphate isomerase ( SgGPI ), trehalose-6-phosphate synthase/phosphatase SgT6PS sucrose synthase SgSUS ) performed using transgenic Arabidopsis thaliana . Results Among 410 identified putatively involved these metabolic 175 related 235 starch Overexpression A. enhanced leaf area, accelerated flower formation, promoted overall growth compared wild-type Discussion These findings lay foundation understanding roles genes offering insights into future engineering strategies enhancing production valuable or other

Expression Profiling Analysis of the SWEET Gene Family in In Vitro Pitaya Under Low-Temperature Stress and Study of Its Cold Resistance Mechanism

Plants, Journal Year: 2024, Volume and Issue: 13(21), P. 3092 - 3092

Published: Nov. 2, 2024

Pitaya (Hylocereus undatus) fruit is an attractive, nutrient-rich tropical with commercial value. However, low-temperature stress severely affects the yield and quality of pitaya. The relevant mechanisms involved in response pitaya to remain unclear. To study whether SWEET gene family mediates H. undatus related mechanisms, we performed genome-wide identification pitaya, used ‘Baiyulong’ tissue-cultured plantlets as material present study. We identified 28 members from genome divided these into four groups. Members this presented some differences sequences introns exons, but structure, especially motifs, relatively conserved characteristics. promoter regions most HuSWEETs have multiple stress- or hormone-related cis-elements. Three duplicated pairs were identified, including one tandem duplication two fragment pairs. results revealed that genes may regulate transport distribution soluble sugars plants; indirectly enzyme activities CAT, POD, T-SOD through its expression products; are play vital roles process. After ABA MeJA treatment, changed significantly, cold was also alleviated. This elucidated molecular mechanism physiological changes sugar metabolism when it experiences provided a theoretical basis for cold-resistant variety breeding.
