Drought and salinity are two major environmental factors that reduce plant productivity. Many factors interrelate and alter the effect of salinity such as soil fertility, humidity, ambient temperature, light, irrigation, and so on. Generally, the survival and growth of plants are measured to determine the tolerance of plants to salinity. The current experimental study was executed to identify the best suitable maize germplasm for salt affected areas based on their performance. This experiment was conducted at the weir house of Department of Plant Breeding and Genetics, The Islamia University of Bahawalpur using the CRD with their replications to determine the selection criteria for salt tolerant maize genotypes at the seedling stage using Chlorophyll Content, Root length, Shoot length, Root fresh weight, shoot fresh weight, Root dry weight, Shoot dry weight and Root shoot ratio. The 06 genotypes were assessed under normal and heat stress using factorial Complete Randomized design. Analysis of variance showed a significant and non-significant variation among the studied germplasms. The root fresh weight and shoot fresh weight were correlated with root dry weight and shoot dry weight under both normal and stress conditions. So, selection on the base of these traits enhances the performance of other traits. The root length and chlorophyll content were non-significant and negatively associated with all other studied characters. The results recommended that selection for root length and chlorophyll content could not be suitable for salinity tolerance. The genotypes which performed good under salinity stress conditions can be useful in future maize breeding programs, and evaluation of salinity stress tolerant germplasm on the base of studied traits.

“…Owing to the complexity, variability, and dynamic changes in phenotype formation, the study of phenotypes is relatively slow. Phenotypic traits are the most intuitive expression of plant adaptation to stressful environments, and comprehensive and accurate phenotypic information is essential to perform in-depth evaluations on the function of related genes and reveal their regulatory networks [18,19].…”

The low availability of phosphorus has become a common problem worldwide. Phosphorus is essential for phenotypic morphology and ginsenoside synthesis. However, the effects of Pi stress on ginseng phenotype and ginsenoside synthesis remain unclear. Phenotypic analyses and transcriptomics revealed the phenotypic construction and regulation of differential genes involved in the physiological metabolism of ginseng under low-Pi stress. Root length and stem length were found to be significantly inhibited by phosphate-deficiency stress in the half-phosphate (HP) and no-phosphate (NP) treatment groups; however, the number of fibrous roots, which are regulated by phytohormones, was found to increase. In ginseng leaves, the indexes of physiological stress, superoxide anion (221.19 nmol/g) and malonaldehyde (MDA) (0.05 μmol/min/g), reached the maximum level. Moreover, chlorophyll fluorescence images and chlorophyll content further confirmed the inhibition of ginseng photosynthesis under low-Pi stress. A total of 579 and 210 differentially expressed genes (DEGs) were shared between NP and total phosphate (TP) and HP and TP, respectively, and only 64 common DEGs were found based on the two comparisons. These DEGs were mainly related to the synthesis of phosphate transporters (PHTs), phytohormones, and ginsenosides. According to KEGG analyses, four DEGs (Pg_s 0368.2, Pg_s3418.1, Pg_s5392.5 and Pg_s3342.1) affected acetyl-CoA production by regulating glycometabolism and tricarboxylic acid cycle (TCA). In addition, related genes, including those encoding 13 PHTs, 15 phytohormones, and 20 ginsenoside synthetases, were screened in ginseng roots under Pi-deficiency stress. These results indicate that changes in the ginseng phenotype and transcriptional regulation of DEGs are involved in the Pi-deficiency stress environment of ginseng, thereby providing new information regarding the development of ginseng for low-Pi tolerance.
