Summary: Sunflower downy mildew is a serious disease that significantly reduces sunflower yields worldwide. Understanding the spread and evolution of the pathogen population is crucial for developing resistant sunflower lines. In this study, the presence of the resistance gene Pl(36) in the sunflower line 803-1 was confirmed and its genetic mapping was conducted.

Summary: This study investigated the effects of nickel application on physiological and biochemical attributes of sunflower cultivars grown in sand culture. Results showed that increasing nickel concentration significantly decreased vegetative parameters and photosynthetic attributes, while low levels of nickel improved growth attributes to some extent. The study also found that high nickel concentration had negative effects on leaf water potential, osmotic potentials, and relative water contents, but increased leaf turgor potential and membrane permeability. Hysun-33 exhibited higher tolerance to nickel stress compared to SF-187.

Summary: This study investigated the resistance against basal stalk rot (BSR) caused by Sclerotinia sclerotiorum in cultivated sunflower, introgressed from the wild sunflower Helianthus praecox ssp. runyonii. The research identified 19 BSR resistance quantitative trait loci (QTL) on nine sunflower chromosomes, with 16 of them deriving resistant alleles from H. praecox parent. These findings provide genetic markers for marker-assisted breeding to combat BSR in sunflower.

Summary: Sunflower exhibits strong alkali tolerance. Alkali stress alters the lipid components of sunflower seeds, potentially affecting the quality of sunflower seed oils. Alkali stress promotes the accumulation of various substances in sunflower roots. Interaction of multiple phytohormones and bioactive molecules play a role in mediating alkali tolerance in sunflower.

Summary: This study identified loci governing basal stalk rot (BSR) resistance derived from H. petiolaris through an advanced backcross population (AB-QTL). A total of 14 QTL associated with BSR resistance were identified on nine chromosomes, with most alleles conferring increased BSR resistance coming from the H. petiolaris parent. The results suggest the potential for breeding sunflower cultivars with improved resistance to the BSR pathogen.

Summary: This study identified major loci associated with nectar volume variation in sunflower using genetic mapping. Increased nectar volume was found to be associated with increased sugars and total energy per floret. Candidate genes on chromosomes were found to be homologous to genes with nectary function in Arabidopsis.

Summary: This study provides the first comprehensive characterization of the WOX family in sunflower, a member of the Asteraceae family. Through phylogenetic analysis, 18 putative HaWOX genes were identified and classified into three major clades. These genes show conserved structural and functional motifs and are evenly distributed on sunflower chromosomes. Gene expression analysis reveals a specific pattern of regulation during embryo growth and meristem differentiation, suggesting a pivotal role for the HaWOX family in sunflower development.

Summary: This study used DNA-based analysis to determine the genetic purity of 23 sunflower parents and their 60 hybrids. The researchers used SSR markers to analyze the polymorphism and identified the allele sizes of the parents and hybrids. The results showed that the hybrids had similar allele sizes to their parents, confirming the genetic purity. The findings of this study are important for accurate identification of hybrids and improving seed genetic purity testing globally.

Summary: Infection by a plant pathogen leads to the production of reactive oxygen intermediates (ROIs) in the plant, which play an important role in plant resistance. Susceptible genotypes exhibit higher levels of ROIs, resulting in cell damage, while resistant genotypes have lower levels of ROIs and higher antioxidant enzyme activities.

Summary: This study investigated the translocation of foliar-applied zinc in sunflower leaves using synchrotron-based X-ray fluorescence microscopy (XFM) and transcriptome analysis. The results showed that the distribution of zinc changed over time, with initial accumulation in the epidermal layers and subsequent movement to the vascular tissues. Transcriptome analysis revealed genes involved in stress response, cell wall reinforcement, and binding. These findings are of significance for improving the efficiency of foliar zinc fertilizers.

Summary: The study focused on the effect of varying sowing dates on sunflower genotypes' seed dormancy levels, finding that late sowings can increase germination rates and accelerate dormancy release. The sensitivity of embryos to ABA inhibition may play a role in alleviating dormancy in sunflower seeds.

Summary: An extruded magnesium AZ31 alloy was processed by rotary swaging and then deformed by tension and compression at room temperature. The work-hardening behavior was analyzed, indicating that dislocation accumulation on obstacles and twin boundaries plays a decisive role in strain hardening. Profuse twinning in compression leads to higher hardening, while the main softening mechanism is attributed to cross-slip between pyramidal planes of different orders.
