TL;DR

Transgenic evaluations confirmed that OsSLT1 acts as a positive regulator of salt tolerance at the seedling stage, and no significant changes in Na+ or K+ accumulation were observed in flag leaves under the tested salt-stress condition, suggesting that OsSLT1 may regulate salt tolerance through mechanisms beyond classical shoot ion accumulation.

Integrated Genome-Wide Association and QTL Mapping Elucidate the Genetic Basis of Fruit Yield and Quality Traits in Pepper under Water Stress.

Water deficit is a major constraint on pepper (Capsicum annuum) yield, yet the genetic architecture of reproductive-stage drought tolerance remains poorly resolved. We phenotyped a Balkan C. annuum diversity panel (n = 133) and an interspecific backcross inbred line (BIL) population (n = 76) under well-watered (WW) and...

Phylogenetic diversity and genome-wide association mapping of salt tolerance traits in Cambodian rice germplasm

The screening at the seedling stage showed CAR 11 was a highly salt-tolerant variety in response to salt stress, suggesting this variety could be used in actual salt-affected fields using the transplanting method and may also serve as a valuable genetic resource for salt-tolerance breeding.

Genome-Wide Association Study and Identification of Core Candidate Genes for Shoot and Root Length in Wheat During Germination

The genetic architecture and core candidate genes for shoot length (SL) and root length (RL) at the germination stage are dissected and seven core candidate genes for SL and 13 for RL are identified, including three pleiotropic genes regulating both traits.

Genome-wide Association Study of Total Root Weight at the Seedling Stage in Korean Rice Cultivars (Oryza sativa L.)

Root biomass is an important determinant of seedling vigor that contributes to water and nutrient acquisition in rice (Oryza sativa L.). In this study, we evaluated the total root weight (TRW) of 127 Korean rice cultivars, comprising 110 temperate japonica (TEJ) and 17 Tongil-type cultivars, under hydroponic conditions...

Genetic Dissection and Fine-Mapping of QTL for Salinity Tolerance at the Reproductive Stage on Chromosome 2 of Rice Variety Nona Bokra

Soil salinity is a major constraint limiting rice productivity, particularly at the reproductive stage. To elucidate the genetic basis of reproductive stage salinity tolerance, this study validated and fine-mapped quantitative trait loci (QTL) for yield-related traits using a salinity-tolerant line SL506, identified th...

Genome-Wide Association Studies of Agronomic and Yield Traits in Sweet Corn (Zea mays L. var. saccharata)

Sweet corn is a globally important dual-purpose crop for both food and fresh vegetables. The plant architecture and ear-related traits directly determine its yield potential and field ecological adaptability. To elucidate the genetic architecture of these traits and identify superior alleles for breeding, we conducted...
