Blueberries are a relatively recently domesticated species, primarily bred through hybridization. Mutation breeding, which uses chemical or physical treatment to increase plant mutation, has not yet been applied blueberries. This study introduces mutation breeding strategy for the highbush blueberry cultivar Vaccinium corymbosum. We established high-efficiency regeneration protocol, was leaves and stems exposed gamma irradiation using 60Co-γ rays at doses of 10, 20, 40, 80, 120 gray (Gy), efficiency mutated cells develop into adventitious shoots. determined that median lethal dose (LD50) approximately 56 Gy leaf explants 80 stem explants. Phenotypic variations, including changes in color growth characteristics, may be due altered response environmental factors, were successfully observed first-generation (M1) plants. The height M1 plants quantitatively decreased with increasing doses. To evaluate mutants induced by each dose, whole-genome resequencing conducted on individuals from group, revealing significant genomic alterations dose. approach provides valuable reference future programs aimed enhancing genetic diversity improving performance.

Heterotrimeric G-proteins: multi-dimensional regulation in plant growth, development and abiotic stress responses

Stress Biology, Journal Year: 2025, Volume and Issue: 5(1)

Published: Jan. 6, 2025

Abstract Heterotrimeric G-proteins, comprising Gα, Gβ, and Gγ subunits, act as crucial molecular switches for signaling transduction in all eukaryotic organisms. Through precise modulation of specific receptors or effectors coupled with heterotrimeric G-proteins cascades, plants have the capability to activate suppress unique pathways necessary plant growth, development, stress responses. This review provides an overview pathway obtained date, highlights novel areas future exploration agricultural application based on emerging significance potential G proteins regulating development responses abiotic stress.

Integrating high‐throughput phenotyping and genome‐wide association studies for enhanced drought resistance and yield prediction in wheat

New Phytologist, Journal Year: 2024, Volume and Issue: 243(5), P. 1758 - 1775

Published: July 11, 2024

Summary Drought, especially terminal drought, severely limits wheat growth and yield. Understanding the complex mechanisms behind drought response in is essential for developing drought‐resistant varieties. This study aimed to dissect genetic architecture high‐yielding ideotypes under drought. An automated high‐throughput phenotyping platform was used examine 28 392 image‐based digital traits (i‐traits) different conditions during flowering stage of a natural population. Of i‐traits examined, 17 073 were identified as drought‐related. A genome‐wide association (GWAS) 5320 drought‐related significant single‐nucleotide polymorphisms (SNPs) 27 SNP clusters. notable hotspot region controlling tolerance discovered, which TaPP2C6 shown be an important negative regulator response. The tapp2c6 knockout lines exhibited enhanced resistance without yield penalty. haplotype analysis revealed favored allele that significantly correlated with resistance, affirming its potential value breeding programs. We developed advanced prediction model using 24 analyzed by machine learning. In summary, this provides comprehensive insights into ideotype approach rapid wheat.

Evaluating Drought Tolerance in Codonopsis pilosula Seedlings: Combining Growth, Physiology, Yield, and Tolerance Indices

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(4), P. 1600 - 1600

Published: Feb. 13, 2025

Drought stress during the Codonopsis pilosula (Campanulaceae) seedling stage significantly affects its growth, quality, and yield. The aim of this study was to identify drought-tolerant cultivars C. by using growth-physiology-yield composite index (GPYCI) indices. Nine were evaluated under normal-watered (black plastic film hole sowing, BF) water-stressed (spread in open field, SF) conditions a design that adopted two-factor paired experiment with three replications. emergence rate influenced water treatment, while both treatment cultivar affected root length, proline content, APX activity, chlorophyll levels. G1 performed better than others multiple aspects. Yields their attributes varied among different average yield 7350.76 kg/hm2 BF 4856.32 SF conditions. reduced total single fresh weight, 18.33%, 28.4%, 33.9%, respectively. Correlation analysis revealed unique physiological response mechanisms changes cultivars. tolerance indices comprehensive factor indicated varying levels drought This has provided valuable insights into physiology, laid foundation for breeding

The drought resistance of rice is an indirect observational and complex trait whose phenotype reflected in the response directly traits to stress. To objectively accurately evaluate rice, soil moisture gradient quantification was designed as a general water index among different types. Through control, consumption calculation, yield test, examination, statistical analysis, relationship between quantitative control treatment studied establish controllable evaluation system resistance. Four kinds gradients, namely, 100%, 80%, 60%, 40% field capacity, were experiment. Six tested varieties grew under long-term treatment. four levels capacity from transplanting returning green maturity. calculation actual shows that design formed significant reached very difference. (GQWC) significantly influenced tiller formation, grain yield, component traits, use efficiency. Under GQWC treatment, difference wide ecological amplitude. There levels. differences differ due various gradients direct traits. It difficult with single gradient.
