Summary: This study identified 30 cyclophilin genes in the 'Golden Delicious' apple genome and categorized them into three clades. The analysis also revealed the involvement of MdCYP16 as a nuclear-localized MD cyclophilin in response to salt and drought stress in apple. The research provides valuable insights into the apple cyclophilin gene family and offers candidate genes for stress response in apple.

Summary: The study investigated the effects of a plant growth regulator and low O2 controlled atmosphere storage on the surface microbiome of 'Gala' apples. It was found that the storage conditions influenced the composition, diversity, and function of the microbiomes inhabiting fruit surfaces. The results provide a greater understanding of biocontrol and pathogen population dynamics.

Summary: This study investigated the reproductive biology of traditional apple cultivars in the Basque-style cider-producing area in northern Spain. The results showed that some varieties have good pollen quality, while others are not suitable for self-pollination. Furthermore, the study identified rare S26 and novel S60 alleles in the region. These findings will contribute to improving orchard management and increasing potential yields.

Summary: Apple production is significantly affected by apple scab disease caused by the fungus Venturia inaequalis. Breeding for polyploid cultivars could enhance resistance of apple cultivars against different V. inaequalis isolates. The role of polyploidy in conferring resistance to biotic challenges is plant-pathogen-specific.

Summary: MdbHLH51 plays a crucial role in the coloration and accumulation of anthocyanins in apple fruits, promoting the red coloring of fruit skin through enhancing the accumulation of anthocyanins. Additionally, MdbHLH51 can also increase the anthocyanin content in other plants.

Summary: The pattern of cuticle deposition is crucial in managing strain buildup in fruit cuticles. Recent evidence suggests a strain gradient within apple fruit cuticle, with outer layers being more strained and prone to microcracking. The deposition of cutin primarily occurs on the inner surface of the cuticle, resulting in a radial gradient in cuticular age.

Summary: A high-performance nitrogen-doped chitosan-TiO2 nanocomposite was successfully prepared by a simple precipitation method and showed significant photocatalytic activities for the degradation of patulin in apple juice. The nanocomposite effectively degraded patulin within 35 minutes under ultraviolet irradiation, with little impact on the quality of apple juice.

Summary: Microscopic cracks are causative in fruit skin disorders of apple, while deposition of cuticle can reduce these cracks. Feeding C-13-labeled oleic acid to developing apple fruit surface results in rapid incorporation, with some cultivars showing higher incorporation. The rate of incorporation decreases over time during fruit development.

Summary: The effects of targeting the key gene MdPGT1 involved in phloridzin biosynthesis in apple using conventional transgenesis and CRISPR/Cas9-mediated genome editing were simultaneously assessed. Knockdown lines showed impaired growth and leaf morphology, while genome-edited lines exhibited normal growth despite reduced phloridzin levels. Transcriptomic and metabolic analyses revealed regulated genes involved in phenylpropanoid and flavonoid pathways. Phytohormone profiling demonstrated differential modulation, with increased salicylic and jasmonic acid levels in dwarf lines and no correlation between auxin and ABA with growth phenotype.

Summary: Bitter pit is a relevant post-harvest disorder for the apple industry, usually related to calcium deficiency. XRF technology can be used to predict the incidence of bitter pit by analyzing the signal intensity of various mineral elements in the fruit. The study found that, in addition to potassium and calcium, other elements also play a key role in bitter pit prediction.

Summary: MdPG1 encoding polygalacturonase is a key gene related to fruit firmness and texture variations in apple. We identified a SNPA/C variant in the promoter region of MdPG1 and found that the promoter with SNPA could be strongly bound and activated by MdCBF2, while the promoter with SNPC could not. We also discovered a novel long non-coding RNA, lncRNA(PG1), in the promoter of MdPG1, which was a causative variant. Our study provides new insights into the genetic regulation of MdPG1 allele expression and has implications for apple breeding.

Summary: The study investigated the distribution of streptomycin-resistant Erwinia amylovora strains in major apple production regions of New York over the past 6 years, revealing a few cosmopolitan strains and novel CRISPR profile diversity across regions. Streptomycin-resistant E. amylovora was detected in a small area and associated with specific CRISPR profile, suggesting the original strain was not fully eradicated and went undetected due to low disease pressure.

Summary: Sweetness is a crucial factor for consumer preference in apples, however, there is no established method for producing apples high in soluble solids content (SSC). Through a regression model, we found that solar radiation and crop load significantly affect the SSC of fruit. Additionally, there is a strong correlation between starch content and SSC at harvest. Therefore, restricting the number of fruits per tree during growth can increase the SSC in apples.

Summary: The composition of bacterial and fungal endophytes within the phyllosphere of apple trees is influenced by host genetics and environment. A study on apple trees infected with the fungal pathogen Neonectria ditissima showed that multiple loci have a significant effect on the abundance of individual endophytic taxa. Some of these loci are associated with tolerance to Neonectria ditissima. These findings suggest that apple endophyte composition has a genetic basis and can be modified through breeding.

Summary: Polyploidization is an important source of variability for breeding, with newly obtained tetraploids showing enhanced resistance to apple scab. However, tetraploids of 'Free Redstar' exhibit poor growth compared to diploid plants, especially during the early growth phase, with differences in morphological parameters noted between the two types of plants.

Summary: Research was conducted on 36 Japanese plum cultivars at an Experimental Orchard in Dabrowice near Skierniewice from 2015 to 2020, focusing on various aspects including frost resistance, susceptibility to sharka, flowering biology, fruit setting, yield, and ploidy levels. The findings revealed that some cultivars were susceptible to frost and sharka disease, while others performed well in the climate of Central Europe.

Summary: Interspecific hybridisation plays a crucial role in the formation of allopolyploid cultivars in Brassica. This study examined the ploidy of F-1 and F-2 generations resulting from interspecific hybridisation between different Brassica lines and evaluated the effect of meiotic polyploidisation on phenotypic and anatomical traits. The results showed that F-2 hybrids had superior agronomic traits and pollen viability compared to parental lines and F-1 hybrids.

Summary: The study concludes that the morphological traits and nuclear DNA content of narcissus can be used to determine the possible ploidy level. The information on the origin and parental forms of narcissus can also be helpful in determining the ploidy level. However, further confirmation of the ploidy level requires verification of chromosome number and preferably karyotyping.

Summary: Polyploids, including octoploids, are commonly used in breeding programs for horticultural plants due to their vigorous growth and enhanced resistance to stress. This study successfully induced octoploidy in Saskatoon berry through in vitro cultures, resulting in the first octoploid individuals of the genus Amelanchier. However, the octoploids exhibited slow growth and a tendency towards premature dormancy.

Summary: This work focuses on the achievements of Polish researchers in the field of vegetative reproduction of plants under in vitro conditions. Micropropagation methods have been used in Poland for over 50 years whenever clonal reproduction is needed. Different regenerative and in vitro propagation systems have been developed to achieve goals such as pathogen elimination, reproduction of healthy plants, rapid multiplication of valuable breeding lines and cultivars, and breeding for polyploids, haploids, and doubled haploids.
