Summary: This study identified QTL for salt tolerance and ion content in leaves under salt stress in barley and revealed the mechanisms of salt tolerance controlled by two major QTL. It also challenged the traditional view on the role of HvHKT1;5 transporters in Na(+) exclusion in barley's adaptive response to salinity stress.

Summary: The study identified that GmSALT3 plays a significant role in salt tolerance by promoting net influx and accumulation of Na+, K+ and Cl- in plant cells. Grafting experiments demonstrated that shoot Cl- exclusion is dependent on the presence of GmSALT3 in shoots, revealing a novel mechanism for salt tolerance in plants.

Summary: In this study, genetic diversity and population structure in eighty-eight Aegilops accessions were evaluated under control and water deficit stress conditions using various physio-chemical traits and SSR markers. The results indicated significant correlations between photosynthetic pigments and antioxidant enzyme activity, with genetic diversity mainly observed among populations. Eight MTAs showed stable expression across both conditions, and Xgwm-455 marker was associated with multiple traits. This study contributes to the understanding of genetics and breeding for key physio-chemical properties.

Summary: Soil salinity is a major constraint that affects plant growth and development, especially rice. The ability of the plant to exclude cytosolic Na+ is strongly correlated with salinity stress tolerance. A study comparing cultivated rice and wild rice found that salt-tolerant cultivated rice relies more on cytosolic Na+ exclusion mechanism to deal with salt stress, regulated at a post-translational level.

Summary: Aegilops cylindrica Host is a highly salt-tolerant species within the Triticeae tribe. Amphidiploid plants derived from hybridization with contrasting salt tolerance genotypes showed similar traits to A. cylindrica under salt stress, with significant differences in gene expression patterns. These findings suggest that the hybridized amphiploids could be valuable resources for improving salt tolerance in wheat through the backcrossing approach.

Summary: The formation of allotetraploid wheat through allotetraploidization of A and S genome species had a dominant effect on salinity tolerance. The concentration of Na+ in leaves was not the key factor determining salt sensitivity, while ROS metabolism and flavonoid concentration played important roles in salt sensitivity.

Summary: In this study, novel genomic-SSR (g-SSR) markers were used to characterize Tinospora cordifolia and related species. The g-SSR marker was compared with EST-SSR and SCoT markers and found to be a better marker for genetic diversity studies of T. cordifolia. In addition, the g-SSR marker showed high cross-species transferability, making it useful for studying related species.

Summary: Lodging is a crucial factor affecting wheat yield, and Emmer wheat is a potential gene source for improving durum wheat, despite being highly susceptible to lodging. The genetic studies on the traits related to lodging in durum x emmer crosses are limited. Additive gene actions play a major role in controlling lodging-related traits, with potential for increasing genetic gain through selection for reduced plant height and increased stem diameter.

Summary: Evaluation of drought tolerance in tall fescue native Iranian landraces and assessment of genotype x environment interaction has been rarely studied. Water stress had a negative impact on dry forage yield and genetic variation, particularly in foreign genotypes. The stress tolerance index and multivariate analysis methods identified the most stable and high-yielding drought-tolerant genotypes.

Summary: Improving flower yield in saffron is a major goal in breeding, and one way to achieve this is by using plant growth regulators such as methyl jasmonate and 6-benzyl amino purine. These hormones regulate the expression of flowering-related genes and affect the activity of antioxidant enzymes and nutrient content. This study found that treatments with methyl jasmonate and 6-benzyl amino purine resulted in changes in gene expression and enzyme activity, suggesting their significant role in the transition from vegetative to reproductive phase in saffron.

Summary: This study investigated the genetic basis of salt tolerance in wheat plants under salinity stress conditions, revealing the importance of additive genetic variance, epistatic gene effects, and the six-parameter model in controlling traits such as plant height, K/Na, and yield. The findings highlight the significance of total chlorophyll, carotenoid, SPAD chlorophyll, and K/Na ratio in saline conditions, as well as the implications for developing salt-tolerant wheat cultivars.

Summary: By comparing the transcriptomic profiles of salt-tolerant and salt-sensitive barley genotypes under salt stress conditions, this study found that the wild barley genotype showed better tolerance to salt stress due to higher expression levels of salt-tolerance related genes. These differences provide insights into the salt-tolerance mechanism in wild barley and can contribute to a better understanding of salt tolerance in barley species.

Summary: The popular perception that gluten-containing foods are bad for health has led to the promotion of 'ancient grains' with claims of lower gluten content. However, analysis shows that ancient wheats actually have higher protein and gluten content, along with more CD-active epitopes. Therefore, no specific wheat type can be recommended for reducing the risks or severity of CD.

Summary: Better understanding of the genetic structure of economic traits is important for forage plant breeding. The present study used the REML/BLUP procedure to assess genetic variation, estimate genetic parameters, and predict breeding values in tall fescue. The results showed significant genotypic variability for all traits, with non-additive gene actions playing an important role in the inheritance of dry forage yield. Traits related to yield and flowering time were found to have higher heritability and significant genetic correlations with forage yield, suggesting their potential for indirect genetic improvement. The study demonstrated the suitability of the REML/BLUP procedure for identifying and selecting superior genotypes in tall fescue breeding programs.

Summary: This study characterized productivity, post-drought recovery, and persistence in the medicinal plant fennel. High genotypic variation and associations between phytochemical properties and post-drought recovery or persistence were observed. The highest persistence and essential oil content were found in ssp. piperitum and var. dulce, respectively. Seed yield and persistence were negatively associated, and post-drought recovery was negatively associated with fenchone and estragole but positively associated with trans-anethole. Results indicate the possibility of indirect selection for post-drought recovery and persistence through phytochemical properties.

Summary: Association analysis was conducted to identify the associations of recovery, persistence, and summer dormancy with SRAP markers in smooth bromegrass genotypes. Polymorphic markers were identified and association analysis revealed marker-trait associations under normal and water deficit regimes. The markers could potentially be used for marker-assisted selection and targeted trait introgression for the improvement of drought tolerance in smooth bromegrass.

Summary: Limited information is available on the impact of deliberate selfing compared with open-pollination and its interaction with water deficit on productivity and phytochemical constituents of essential oil in fennel. This study found that water deficit greatly decreased grain yield and essential oil content, while increasing other constituents. Selfing reduced the yield of seeds and essential oil compared with open-pollination and also affected other constituents. Genetic analysis showed that additive gene action played an important role in controlling most traits.
