“…This agrees with previous results obtained for drought-stressed rice, in which a reduction in 1000-grain weight [57] was observed, and to the premise that drought stress contributed to a yield reduction in rice lines [58]. In soybean, seeds grown under adverse climatic conditions also had a lower 100-grain weight [59].…”

The identification of the genes responsible for complex traits is highly promising to accelerate crop breeding, but such information is still limited for popcorn. Thus, in the present study, a mixed linear model-based association analysis (MLMA) was applied for six important popcorn traits: plant and ear height, 100-grain weight, popping expansion, grain yield and expanded popcorn volume per hectare. To this end, 196 plants of the open-pollinated popcorn population UENF-14 were sampled, selfed (S 1 ), and then genotyped with a panel of 10,507 single nucleotide polymorphisms (SNPs) markers distributed throughout the genome. The six traits were studied under two environments [Campos dos Goytacazes-RJ (ENV1) and Itaocara-RJ (ENV2)] in an incomplete block design. Based on the phenotypic data of the S 1 progenies and on the genetic characteristics of the parents, the MLMA was performed. Thereafter, genes annotated in the MaizeGDB platform were screened for potential linkage disequilibrium with the SNPs associated to the six evaluated traits. Overall, seven and eight genes were identified as associated with the traits in ENV1 and ENV2, respectively, and proteins encoded by these genes were evaluated for their function. The results obtained here contribute to increase knowledge on the genetic architecture of the six evaluated traits and might be used for marker-assisted selection in breeding programs.

“…ERF transcription factors are AP2/EREBP proteins that contain only one AP2 domain and constitute the largest subfamily of the AP2/EREBP family [ 78 ]. Although a direct relationship has not been identified between GRMZM5G846057 and GY, this trait seems to be directly influenced by abiotic stress, as reported in several studies [ 79 , 80 , 81 , 82 , 83 ]. Therefore, it is possible to suggest that the trait GY is related to responses to stresses and when there is a reduction in grain yield, there is also overexpression of the GRMZM5G846057 gene, which codes AP2/EREBP, related to stresses in plants.…”

The method of regional heritability mapping (RHM) has become an important tool in the identification of quantitative trait loci (QTLs) controlling traits of interest in plants. Here, RHM was first applied in a breeding population of popcorn, to identify the QTLs and candidate genes involved in grain yield, plant height, kernel popping expansion, and first ear height, as well as determining the heritability of each significant genomic region. The study population consisted of 98 S1 families derived from the 9th recurrent selection cycle (C-9) of the open-pollinated variety UENF-14, which were genetically evaluated in two environments (ENV1 and ENV2). Seventeen and five genomic regions were mapped by the RHM method in ENV1 and ENV2, respectively. Subsequent genome-wide analysis based on the reference genome B73 revealed associations with forty-six candidate genes within these genomic regions, some of them are considered to be biologically important due to the proteins that they encode. The results obtained by the RHM method have the potential to contribute to knowledge on the genetic architecture of the growth and yield traits of popcorn, which might be used for marker-assisted selection in breeding programs.

“…Masoumi et al [38] indicated that activities of the antioxidants (CAT) were increased in all levels of water deficit stress in soybean cultivars. Induction of oxidative stress in drought-stressed plants reported in the previous studies [12,37]. They showed that enzymatic antioxidants content played an important role in scavenging harmful oxygen species and the activities of antioxidant enzymes were altered when plants were subjected to stress.…”

Plot trials were carried out in a research field in Tehran (Iran) to determine the effect of drought stress on the essential oil content and some of the plant biochemical characteristics of Anise Hyssop (Agastache foeniculum [Pursh] Kuntze), which is a valuable medicinal plant. Drought stress was conducted at different levels including: well-water (100% FC), mild drought stress (85% FC), moderate drought stress (70% FC), severe drought stress (55% FC), 100% FC (vegetative stage) 85% FC (reproductive stage), 100% FC (vegetative stage) 70% FC (reproductive stage), and 85% FC (vegetative stage) 100% FC (reproductive stage). The experiment was arranged as a RCBD with three replications. The output results showed that, water deficit stress significantly (P≤0.05) increased activities of antioxidant enzymes (Superoxide Dismutase, Catalase, Glutathione Peroxidase) as well as Essential Oil yield and Abscisic Acid content. Lipid and protein oxidation (malondialdehyde and dityrosine contents) also increased significantly under severe water deficit stress. According to the results, severe drought conduction (55% FC) is the optimum level of soil moisture to plant Anise Hyssop under water deficit stress.
