Summary: Through analyzing the genomes of wild giraffes, the study found evidence of historical gene flow between Nubian and reticulated giraffes. However, contemporary gene flow between these two lineages is minimal. The study also observed a decline in effective population sizes of Nubian and reticulated giraffes. Overall, the findings suggest that these three giraffe lineages have maintained their reproductive isolation.

Summary: This study investigated the impact of different rates of marker genotyping error on the accuracy of genomic prediction using stochastic simulation. The results showed that marker genotyping error can decrease the accuracy of genomic evaluations and result in biased estimates of genomic breeding values. It is recommended to minimize marker genotyping errors to zero in genomic evaluation programs in order to obtain accurate results.

Summary: Climate-sensitive pikas in the Qinghai-Tibetan Plateau and its vicinity have experienced population reduction due to climate changes and human disturbance, while the plateau pika remains common. By sequencing the whole genomes of six closely related species, we found evidence of ancient introgression, lineage replacement, and bidirectional introgression. The strongest gene flow occurred from the dominant plateau pika to ecologically distinct species in peripheral areas. Our findings highlight the differences in hybridization consequences and the unique role of the Qinghai-Tibetan Plateau in conserving evolutionary processes.

Summary: Introgressive hybridization is more common in nature than previously thought, occurring more frequently in sympatric populations of recently diverged taxa. The study on Levant fritillary butterflies shows significant unidirectional gene flow from a distant congener Melitaea didyma to M. acentria, despite at least 5 million years of independent evolution. Elevated differentiation and lower level of introgression on the Z chromosome suggest intrinsic postzygotic barriers.

Summary: Hybridization between Helicoverpa armigera and H. zea was investigated, with heterosis observed during immature development. However, reproductive incompatibilities were also found between parental species and subsequent hybrids. Interspecific gene flow and introgression events were confirmed, suggesting the need to monitor hybridization and resistance to pesticides. Management strategies should be implemented to prevent interspecific crosses and minimize the selection of resistant individuals.

Summary: This study investigated the genetic mapping of plant architecture, flowering time, and maturity traits in cotton, and identified a total of 27 QTLs associated with these traits. The findings suggest that this population structure can help reduce background noise and small effect QTLs, and the germplasm developed in this study may serve as potential pre-breeding material for improving cotton cultivars.

Summary: This study found that the Crna Mlaka fishponds in Central Croatia are at a high risk of being invaded by non-native water frog species, leading to introgressive hybridization and genetic admixture. The presence of hybrid forms and introgressed mtDNA indicates the existence of a unique hybrid swarm in this location. The loss of the hybridogenetic reproductive system of Pelophylax kl. esculentus is also observed.

Summary: Understanding the foraging preferences of honey bees is crucial for increasing crop yields. This study found that floral volatile organic compounds (VOCs) play a significant role in honey bee foraging decisions. Different plant species have varying floral scents, some of which contain repellents that deter honey bees, while others have honey-fruity odors that attract more bees.

Summary: Alternaria brassicae can cause devastating disease in canola and mustard, but effective resistances are currently lacking. Screening of 150 diverse Brassicaceae varieties identified important novel resistances, including complete resistance in Camelina sativa '4076' and Diplotaxis erucoides 'Wasabi Rocket'. Other resistant varieties were also identified, such as Camelina sativa 'CSA', '4144', '405', and '3274'. These findings provide valuable resources for breeding programs to develop resistant commercial varieties and highlight the need to avoid highly susceptible varieties in both breeding and commercial settings.

Summary: The duration of flowering and post-harvest life of flowers are influenced by their senescence. This study investigated the physiological and biochemical changes that occur during the transition from floral bud to senescent flower in Chrysanthemum and Gladiolus. It was found that chemical manipulation at the loose bud stage or partially opened flower stage could delay senescence and improve the post-harvest performance of Chrysanthemum and Gladiolus flowers.

Summary: The study investigates the effects of plant developmental stage, cultivar, and inoculum concentration on the development of Phoma black stem and leaf spot disease and coumestrol production in annual Medicago spp. The results show that disease incidence and severity, as well as coumestrol production, are influenced by plant developmental stage, cultivar, and inoculum level. This study highlights the importance of timely grazing of Medicago stands with lower disease and phytoestrogen levels and the need for increased vigilance at later growth stages to mitigate the risk for grazing animals.

Summary: Rising concerns on CO2 emissions and fossil fuel depletion have prompted the development of technologies that produce hydrogen through zero-emission electrolytic pathways powered by renewables. The use of solid oxide electrolytic cell (SOEC) is a promising emerging technology that offers higher electric efficiency compared to other electrolysers. However, the lack of high-temperature redox stable electrocatalytically active cathode materials limits the potential of SOEC technology. This study investigates the electrochemical performance of different cathodes in steam electrolysis, revealing a promising candidate with excellent performance under certain conditions.

Summary: The lack of resistance in cultivated Brassicas to Lipaphis erysimi has led to significant loss of rapeseed-mustard productivity in India. B. fruticulosa, a wild crucifer, is known to have resistance to L. erysimi. In this study, the defense mechanisms and molecular components of B. juncea-B. fruticulosa introgression lines (ILs) against mustard aphid were evaluated. The ILs were categorized into resistant, moderately susceptible, and susceptible genotypes based on aphid population per plant (APP). Phenotypic assessment revealed that B. fruticulosa had the lowest aphid infestation among the tested genotypes. The activity of catalase (CAT) increased significantly in B. fruticulosa and resistant ILs after aphid infestation, and CAT2 was found to play a key role in resistance to mustard aphid.

Summary: This study assesses growers' perceptions of the value and availability of irrigation water in the Mississippi Delta region. The results show that water is considered important for farming and that agricultural irrigation is believed to be the main cause of groundwater depletion. Although respondents believe there is sufficient water, they also perceive a need for better management and regulation to protect the aquifer and ensure future water availability.
