Ammonium Transporter 1 (AMT1) Gene Family in Pomegranate: Genome-Wide Analysis and Expression Profiles in Response to Salt Stress

Current Issues in Molecular Biology, Journal Year: 2025, Volume and Issue: 47(1), P. 59 - 59

Published: Jan. 16, 2025

Understanding the ammonium (NH4+) uptake and transport systems, particularly AMT1 genes, is important for plant growth defense. However, there a lack of research on identifying analyzing genes in pomegranate, emphasizing need further investigation this area. Five (PgAMT1-1 to PgAMT1-5) were identified, all which contain PF00909 domain, feature transporters. Various characteristics these including gene length, coding sequence chromosomal locations, examined. This study evaluated isoelectric point, hydropathicity, conserved domains, motifs, synteny PgAMT1 proteins. Phylogenetic analysis confirmed homology with previously reported AMT Arabidopsis tomato. The tissue-specific expression revealed distinct patterns: PgAMT1-1 PgAMT1-2 predominantly expressed flowers, PgAMT1-3 exhibited notable roots, leaves, PgAMT1-4 was primarily leaf tissue, while PgAMT1-5 detected both leaves roots. impact salt-induced stress also examined, revealing that PgAMT1-1, PgAMT1-2, reduced under increased salt stress. These modifications can help regulate NH4+ assimilation conditions elevated salinity, maintaining cellular homeostasis ion balance. contributes comprehensive identification AMT1s family pomegranate; however, functional characterization identified PgAMT1s needed.

Effects of Source on the Nitrogen Uptake, Allocation Patterns, and Performance of Strawberry (Fragaria × ananassa Duch.): A 15N-Tracer Study

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 265 - 265

Published: Jan. 18, 2025

Nitrogen (N) is an essential determinant of strawberry growth and productivity. However, plants exhibit varying preferences for sources nitrogen, which ultimately affects its use efficiency. Thus, it imperative to determine the preferred N source optimization indoor production. This study employed 15N-tracer technique investigate effects on uptake, distribution, efficiency, as well plants’ growth, ‘Praratchatan 80’ strawberries in a greenhouse. Five treatments were applied: T1 (5.0 mM 15NO3−), T2 (2.5 15NO3− + 2.5 NH4+), T3 15NH4+), T4 15NH4+ NO3−), T5 (N-free, control) completely randomized design. Significant (p < 0.05) differences observed uptake distribution total concentration among treatments. Sole NH4+ promoted early accelerated flowering, while NO3− enhanced vegetative later-stage nitrogen efficiency (NUE). The application combined was most efficacious, balancing benefits both forms. treatment 15NUE by 46% compared NH4+, mixed demonstrated superior consistent over time. alone or with NO3−, expedited flowering 20 days sole N-free elucidates importance optimizing providing foundation developing tailored N-management strategies. Future research should focus refining ratios timings, exploring molecular mechanisms metabolism, evaluating long-term impacts production sustainability.

Effect of Environmental Variables on Plant Community Formation and Vegetation Dynamics in Northwest Ethiopia

International Journal of Forestry Research, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Identifying plant communities has been a central aspect of vegetation science for centuries, with emphasis on the distribution, composition, and classification communities. This study aimed to assess how environmental variables influence community formation dynamics in northwest Ethiopia. A systematic random sampling technique was employed gather data from 50 plots, each measuring 20 × m, arranged at 100‐m intervals along seven transects. In plot, encountered species their percentage cover‐abundance were recorded, which subsequently transformed into modified Braun–Blanquet scale. Additionally, composite soil samples collected 15 cm subplots analyzed parameters. The Shannon–Wiener index used measure diversity. Hierarchical clustering ordination analyses (DCA RDA) conducted floristic data, respectively, using R software. total 69 woody 64 genera 44 families recorded altitudes ranging 2485 2747 m above sea level. diversity (H) 3.74, evenness (J) 0.90. These high indices showed ecosystem health, stability, reflecting effective interactions, resource utilization. Among 6 terrain 14 edaphic factors, 12 these factors (altitude, slope, aspect, cutting, silt, pH, sand, organic carbon, matter, nitrogen, phosphorus, calcium) found significantly ( p ≤ 0.05) explain variation composition four area. observed patterns underscore need design different conservation measures tailored specific conditions elevations.
