Peanut (Arachis hypogaea L.) is an important oilseed, cash crop grown worldwide mainly in a tropical and subtropical climate. Drought stress (DS) is one of the serious abiotic stresses that alter the morphological, physiological, biochemical and molecular responses of plants and causes huge production loss across the globe. The aim of this study, to investigate the twenty widely grown Korean genotypes at the seedling stage under the control and drought stress conditions, to identify tolerant lines as well as related traits. In addition, the influence of DS and rehydration or recovery after stress on peanut genotypes was also studied. Initial screening showed that given genotypes had a differential response to DS, demonstrating a wide range of variation in tested peanut genotypes during the seedling stage towards the DS. Further, based on investigation of the different growth attributes and biochemical assessment six genotypes (Palkwang, Milkwang, and Daekwang) and (Daekwang, Haeol, and Heukhwaseang) were observed as drought-tolerant and drought-sensitive lines respectively. The findings of this study will aid in the selection of peanut genotypes in future breeding efforts aimed at improving drought tolerance and minimizing peanut production loss.

First initiation of breeding started thousands of years ago when human practiced selection based in visually appealing traits. Further, domestication of wild plants eased adaptation of plant breeding. With increase in population the demand for food also increased which resulted in development of various breeding methodologies. Conventional breeding is a selective breeding methodology where crops are selected based on superior performances. Pure-line selections, mass selection, back cross breeding, recurrent selection, hybridization were most famous traditional breeding methods. It is a longer breeding method and is over-dependent on phenotype of plants. However, phenotypes of a plant are affected by various externalities. So, selection based on phenotypic expression is not accurate. As a result, breeder started integrating various branches of biology in plant breeding and developed modern breeding practices. After Mendelian theory and identification of DNA and RNA, plant breeding diverted to molecular era. People started breeding based on less environmentally susceptible parameters like genotypes, visual and genetic markers, image analysis and loci mapping. Some of the most common modern breeding practices include genomic selection, markers assisted breeding, high throughput phenotyping and CRISPR-Cas9. Despite these, plant breeding has fired up the problems of gene erosion due to loss of local landraces and wild-type plants.

This study estimated the genetic variability and gene action of several traits in the F4 and F5 rice populations to determine a trait for selection program. The trait of date to flowering and date to harvesting had narrow genetic variability, whereas trait productive tillers, number of fertile grain, and total grains had moderate to wide genetic variability. Genetic variability in trait number of fertile grain and total grains showed decreased in F5 generation compare to the F4 generation, whereas trait productive tillers, date to flowering, and date to harvesting showed an increase. Additive gene action with duplicate and complementary epistasis was found in all traits, except for trait productive tillers only showed additive gene action with duplicate epistasis. Kurtosis less than 3 was found in all traits which indicate many genes control the traits. The number of fertile grain trait showed wide genetic variability which decreased in F5 generation compare to the F4 generation, and there is an additive gene action with duplicate epistasis. It indicates selection will be effective with the trait of number of fertile grain.

Plant breeders have accumulated hybrid effects to increase food production in order to counteract the loss of arable land. Hybrids may possess novel genetic potential to increase agricultural productivity; however, the relationships between genetic resources for optimizing crop productivity remain mostly unclear. In this study, we recorded heterosis effects of genetically inherited traits by reciprocal hybridization of the Solanum lycopersicum cultivar Micro-Tom and the commercial cultivar M82, which are currently available as in silico mutant populations, to identify mutant genes which can induce heterosis. The genetic variations between M82 and Micro-Tom caused intermediate phenotypic effects with regard to flowering time, plant height, and fruit size, indicating additive interactions among variations with a hybrid background. The total yield of F1 hybrid was similar to that of cultivar M82, regardless of reduced vegetative biomass, and it revealed an overdominance effect regarding number of harvested fruits. The inheritance of the phenotypes was similar among reciprocal F1 hybrids with different paternal and maternal materials. Based on the consistency of hybrids and wild types, Micro-Tom mutants showing floral homeotic defects and large plant size can be efficiently screened for overdominant yield mutants in F1 hybrids. Therefore, we suggest that identical traits in reciprocal hybrids between Micro-Tom and M82 varieties are useful as control F1 hybrids to improve field tomato productivity by screening mutant hybrids of Micro-Tom mutants and commercial variety M82.

Doubled haploid (DH) technology enables the generation and evaluation of new plant genotypes in ≤ 2 years, which is in stark contrast to the 6-7 years required for conventional breeding. Recently, a few proteins including MATRILINEAL (MTL) were found to trigger haploid induction in monocot plants. However, MTL function in dicot plants remains unclear. Here, we investigate the effects of Arabidopsis PATATIN-RELATED PHOSPHOLIPASE 2A (pPLA-IIα), a maize MTL homolog, on the expression of genes that modulate pollen development and fertilization in Arabidopsis. Quantitative real-time PCR analysis showed that transcript levels of four pollen tube growth-related genes and six pollen guidance- or reception-related genes were increased in the ppla-iiα T-DNA insertion mutant compared with the wild type. In addition, transcript levels of four mitosis- and meiosis-related genes, two hormone-related genes, and a calcium pump-encoding gene were also upregulated in the ppla-iiα mutant, whereas expression levels of genes encoding a synergid-secreted peptide (AtLURE1.1) and calmodulin-activated Ca 2+ -ATPase ion pump 9 (ACA9) protein were downregulated in the ppla-iiα mutant compared with the wild type. Taken together, these results suggest that AtLURE1.1 and ACA9 play positive roles in pPLA-IIα-mediated fertilization. Thus, pPLA-IIα controls fertilization through the modulation of pollen germination and pollen tube growth and guidance in Arabidopsis.

Acer rubrum (red maple) is one of the most important ornamental trees in North America. It is used in urban forestry and landscaping, as well as timber and syrup production. Drought is a major challenge that hinders the development and growth of maples and other tree species. The objective of the present study was to evaluate three red maple cultivars namely, October glory, Autumn red, and Red sunset for their physiological and molecular response to drought stress. Saplings of three cultivars of red maple were subjected to drought stress (up to 28 days unirrigated) in the summer of 2018 and 2019, and leaf samples were used to quantify physiological, biochemical, and expression changes under stress. Decrement of chlorophyll content significantly correlated with the soil moisture content observed in all three genotypes subjected to drought stress. Significant variation in proline concentration, Malondialdehyde levels, and increase in superoxide dismutase (SOD) activity at various stages of the experiments showed the ability of the maple plants to respond to drought stress. RT-qPCR analyses revealed higher and variable expression of drought-responsive genes GGAT1 encoding glutamate-glyoxylate aminotransferase, and CSD2 encoding SOD, in the red maple plants under drought stress. The results from this study indicate that the red maple plants alleviate drought stress by the possible mechanism involving decreased lipid peroxidation, and enhanced production of osmolyte and antioxidants.

From an agricultural point of view, deep learning models can be used in a variety of way to study the agricultural properties of soybean. Object detection can be performed using image or video data on phenotypic traits of soybean. In this project, a study on the phenotype analysis about soybean seed was conducted by artificial intelligence (AI) based on the YOLOv5 model. In model summary, layers and parameters were calculated as 243 and 7020913, respectively. Means of average precision (mAP)@[0.5: 0.95] was recorded as 0.835, 0.739, 0.785 for each class, and Daewonkong (DW) with yellow seed coat color was calculated as the highest value, and landrace with black seed coat color (NG2) revealed the lowest value. As a result of prediction performance in the confusion matrix, each class of DW, NG2, and inbreeding line with green seed coat color (NGT) showed significant correlation of true positive (TP) in the matrix with the same output value for the input value.
