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 examined the effects of salt-tolerant Bacillus subtilis strain Y16 and biogas slurry (BGS) on the growth, physiology, and yield of sunflower under salt-affected soil conditions. The results demonstrated that the combined application of BGS and B. subtilis significantly improved sunflower growth, physiology, and yield, enhancing salt-stress tolerance in the plant.

Summary: Organic substitution is an effective approach to address soil degradation caused by excessive chemical fertilizer use. This study evaluated the effects of different organic substitution proportions on saline-sodic soil properties and sunflower growth, and recommended a 50% organic substitution ratio for optimal results.

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: 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 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 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: The study demonstrated that the concentration of 0.01 mg L-1 of GR24 had a positive impact on callus biomass and salt resistance in sunflowers. This concentration improved the weight and substance content of callus under non-saline conditions and enhanced antioxidant enzyme activity and protective substance content under salt stress conditions.

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 interaction between sunflower and microwave signal is still not fully understood. Our analysis reveals differences in the backscattering response of sunflower in the ascending and descending orbits for VV polarization and VH/VV polarization ratio due to the directional behavior of the flower head. We found that VH/VVdes is a preferable parameter for identifying sunflower phenological stages.

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: 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.
