Apricot trees (Prunus armeniaca L.), renowned for their kernel use, are a vital fruit crop in arid regions, benefiting from resilience to harsh conditions including cold and drought. However, research into the genetic roots of the traits and their inheritances has been limited. To begin the current study, we analyzed the population structure of 339 apricot accessions and the genetic variation of kernel-consuming apricot cultivars using whole-genome re-sequencing. During the years 2019 and 2020, phenotypic data on 222 accessions were examined for 19 traits, encompassing kernel and stone shell characteristics, and the proportion of aborted flower pistils. In addition to other analyses, trait heritability and correlation coefficients were estimated. Stone shell length (9446%) displayed the most significant heritability. This was followed by the length/width ratio (9201%) and length/thickness ratio (9200%) of the shell. The breaking force of the nut (1708%), however, demonstrated very low heritability. Through the application of general linear models and generalized linear mixed models in a genome-wide association study, 122 quantitative trait loci were identified. On the eight chromosomes, the QTLs for kernel and stone shell traits showed a non-uniform distribution. Of the 1614 candidate genes identified across 13 consistently reliable quantitative trait loci (QTLs) detected by two genome-wide association studies (GWAS) methods and/or across two distinct seasons, 1021 were subsequently annotated. The sweet kernel trait was placed on chromosome 5, parallel to the almond's genetic mapping. On chromosome 3, a new region spanning 1734 to 1751 Mb, containing 20 candidate genes, was also discovered. The loci and genes uncovered in this study will be instrumental in advancing molecular breeding techniques, and the candidate genes hold significant promise for understanding the intricacies of genetic control mechanisms.

Soybean (Glycine max), a crucial crop in agricultural production, suffers from diminished yields due to water scarcity. While root systems are essential in environments with limited water availability, the intricate mechanisms behind their operation remain largely uncharted. Our earlier research yielded an RNA-Seq data set extracted from soybean roots at three different developmental stages, namely 20, 30, and 44 days of growth. RNA-seq data analysis in this study led to the selection of candidate genes, likely involved in root growth and development. Individual soybean candidate genes were functionally evaluated in transgenic hairy root and composite plants, accomplished through overexpression in intact soybean systems. Root length and/or root fresh/dry weight increased by up to 18-fold and 17-fold, respectively, in transgenic composite plants due to enhanced root growth and biomass stemming from the overexpression of the GmNAC19 and GmGRAB1 transcriptional factors. Greenhouse environments fostered a considerable upsurge in seed production for transgenic composite plants, resulting in approximately double the yield compared to the control plants. Across various developmental stages and tissues, expression profiling revealed GmNAC19 and GmGRAB1 exhibited their highest expression levels specifically within root tissues, demonstrating a clear preference for root development. Moreover, we ascertained that under conditions of insufficient water, the increased expression of GmNAC19 in transgenic composite plants led to amplified tolerance to water stress. By combining these results, we gain a more comprehensive perspective on the agricultural utility of these genes for cultivating soybean varieties with robust root growth and heightened tolerance for water deficits.

A significant obstacle in popcorn cultivation persists in acquiring and recognizing haploid specimens. The aim was to induce and assess haploids in popcorn, taking into consideration the Navajo phenotype, seedling vigor, and ploidy level. Crossed with the Krasnodar Haploid Inducer (KHI) were 20 popcorn genetic resources and 5 maize controls in our study. A completely randomized design, with three replicates, was used for the field trial. To determine the success of haploid induction and their identification, we considered the haploidy induction rate (HIR) and the rates of misidentification through the false positive rate (FPR) and the false negative rate (FNR). Subsequently, we additionally ascertained the penetrance of the Navajo marker gene, R1-nj. The R1-nj method's preliminary categorization of haploids was followed by their concurrent germination with a diploid standard, and a subsequent assessment of false positive and negative results based on their vigor levels. Using flow cytometry, the ploidy level was evaluated in seedlings collected from 14 female plants. The fitting of a generalized linear model, utilizing a logit link function, was performed on the HIR and penetrance data. The HIR of the KHI, calibrated by cytometry, ranged from 0% to 12%, with an average of 0.34%. Screening for vigor, using the Navajo phenotype, yielded an average false positive rate of 262%. Ploidy screening, under the same criteria, showed a rate of 764%. There were no instances of the FNR. R1-nj's penetrance varied considerably, falling somewhere between 308% and 986%. The temperate germplasm yielded fewer seeds per ear (76) compared to the tropical germplasm (98). Haploid induction is observed in the germplasm of both tropical and temperate regions. To ensure the Navajo phenotype, we advise the selection of haploids, directly validated through flow cytometry to confirm ploidy. Haploid screening, informed by the Navajo phenotype and seedling vigor characteristics, is proven effective in mitigating misclassification. R1-nj penetrance varies according to the genetic background and source of the germplasm. Since maize is a known inducer, the creation of doubled haploid technology in popcorn hybrid breeding requires a resolution to the problem of unilateral cross-incompatibility.

A critical factor in the growth of tomatoes (Solanum lycopersicum L.) is water, and knowing the water condition of the tomato plant is key for efficient irrigation management. genetic cluster The goal of this research is to evaluate the water condition of tomato plants by merging RGB, NIR, and depth image data via a deep learning system. Tomatoes were cultivated using five irrigation levels, adjusted to 150%, 125%, 100%, 75%, and 50% of reference evapotranspiration, calculated according to a modified Penman-Monteith equation, enabling different water states for the plants. Vardenafil The water management of tomatoes was divided into five categories: severe irrigation deficit, slight irrigation deficit, moderate irrigation, slight over-irrigation, and severe over-irrigation. Data sets comprised of RGB, depth, and near-infrared images from the tomato plant's upper region were collected. Using the data sets, tomato water status detection models were trained and tested, with the models being constructed utilizing single-mode and multimodal deep learning networks. In a single-mode deep learning network, a total of six different training configurations were established by training the VGG-16 and ResNet-50 CNNs using a single RGB, depth, or near-infrared (NIR) image. Twenty different training configurations were used in a multimodal deep learning network, each involving combinations of RGB, depth, and NIR images, with individual models trained using either VGG-16 or ResNet-50. In the context of tomato water status detection, single-mode deep learning demonstrated accuracy ranging from 8897% to 9309%. Multimodal deep learning methods, conversely, achieved a higher level of accuracy, fluctuating from 9309% to 9918%. Multimodal deep learning's proficiency was significantly higher than that of single-modal deep learning. A multimodal deep learning network, using ResNet-50 for RGB images and VGG-16 for depth and near-infrared images, was employed to develop an optimal tomato water status detection model. This investigation introduces a novel, non-destructive methodology for determining the water condition of tomatoes, offering a valuable resource for optimized irrigation management.

Strategies for enhancing drought tolerance are employed by rice, a leading staple crop, to consequently improve its overall yield. Plants exhibit enhanced resistance to both biotic and abiotic stresses through the action of osmotin-like proteins. The role of osmotin-like proteins in rice's inherent drought resilience remains an area of ongoing investigation. OsOLP1, a newly discovered protein akin to osmotin in its form and properties, was found to be induced by drought and salt stress in this investigation. Investigating OsOLP1's influence on rice drought tolerance involved the employment of CRISPR/Cas9-mediated gene editing and overexpression lines. Transgenic rice plants overexpressing OsOLP1 displayed remarkable drought resistance compared to wild-type plants, marked by leaf water content as high as 65% and an impressive survival rate over 531%. This resilience was attributable to a 96% reduction in stomatal closure, a rise in proline content surpassing 25-fold, driven by a 15-fold increase in endogenous ABA, and about 50% heightened lignin synthesis. Nevertheless, OsOLP1 knockout lines exhibited a drastic reduction in ABA levels, a decline in lignin accumulation, and a compromised capacity for drought resistance. In essence, the results highlight that the drought-induced alterations in OsOLP1 are correlated with the accumulation of ABA, the management of stomatal function, the elevation of proline levels, and the enhancement of lignin synthesis. These findings offer fresh perspectives on how rice endures periods of drought.
