Icewine fingerprint involved in latitude under climate change.

Aroma plays a crucial role in determining icewine quality and influencing the profit of growers, but the influence of climate change on icewine sustainable production and the diversity of aroma volatiles in icewine among different regions are unknown. Here, we employed aroma volatiles of 8 Vidal icewines from 2 typical premium production regions (Liaoning in China and Ontario in Canada) and an emerging low-latitude mountainous area (Yunnan in China) to project future diversity and sustainability. We found that Ontario and Yunnan's icewines were characterized with intense apricot or peach and tropical fruit aromas, which was consistent with the excellent grade icewine around the world based on 225 icewine aroma datasets from 5 countries.

PavSPLs are key regulators of growth, development, and stress response in sweet cherry.

SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes are plant-specific transcription factors essential for plant growth, development, and stress responses.

Horticulture crop under pressure: Unraveling the impact of climate change on nutrition and fruit cracking.

Climate change is increasingly affecting the nutritional content and structural integrity of horticultural crops, leading to challenges such as diminished fruit quality and the exacerbation of fruit cracking. This manuscript systematically explores the multifaceted impacts of these changes, with a particular focus on the nutritional quality and increased incidence of fruit cracking. An exhaustive review of current research identifies the critical role of transcription factors in mediating plant responses to climatic stressors, such as drought, temperature extremes, and saline conditions.

Comparative genomics of N-acetyl-5-methoxytryptamine members in four Prunus species with insights into bud dormancy and abiotic stress responses in Prunus avium.

This study provides novel insights into the evolution, diversification, and functions of melatonin biosynthesis genes in Prunus species, highlighting their potential role in regulating bud dormancy and abiotic stresses. The biosynthesis of melatonin (MEL) in plants is primarily governed by enzymatic reactions involving key enzymes such as serotonin N-acetyltransferase (SNAT), tryptamine 5-hydroxylase (T5H), N-acetylserotonin methyltransferase (ASMT) and tryptophan decarboxylase (TDC). In this study, we analyzed Melatonin genes in four Prunus species such as Prunus avium (Pavi), Prunus pusilliflora (Ppus), Prunus serulata (Pser), and Prunus persica (Pper) based on comparative genomics approach.

Oxygenation alleviates waterlogging-caused damages to cherry rootstocks.

Waterlogging has occurred more frequently in recent years due to climate change, so it is a huge threat to crop yield and quality. Sweet cherry, a fruit tree with a high economic value, is sensitive to waterlogging stress. One of the most effective methods for enhancing the waterlogging tolerance of sweet cherries is to select waterlogging-tolerant rootstocks.

Chromosome-scale genome assembly of provides novel insights into genome evolution, disease resistance, and dormancy release in L.

is a wild cherry germplasm resource distributed mainly in Southwest China. Despite its ornamental and economic value, a high-quality assembled genome is unavailable, hindering our understanding of its genetic background, population diversity, and evolutionary processes. Here, we assembled a chromosome-scale genome using Oxford Nanopore, Illumina, and chromosome conformation capture sequencing.

Strigolactones modulate stem length and diameter of cherry rootstocks through interaction with other hormone signaling pathways.

Stem growth and development has considerable effects on plant architecture and yield performance. Strigolactones (SLs) modulate shoot branching and root architecture in plants. However, the molecular mechanisms underlying SLs regulate cherry rootstocks stem growth and development remain unclear.

PavGA2ox-2L inhibits the plant growth and development interacting with PavDWARF in sweet cherry (Prunus avium L.).

Dwarf dense planting is helpful to improve the yield and quality of sweet cherry, which has enormous market demand. GA2oxs (GA oxidases) affect plant height, dormancy release, flower development, and seed germination by participating in the metabolic regulation and signal transduction of GA (Gibberellin). However, the research on GA2ox in sweet cherry is little and worthy of further investigation.

Identification and Comprehensive Genome-Wide Analysis of Glutathione S-Transferase Gene Family in Sweet Cherry () and Their Expression Profiling Reveals a Likely Role in Anthocyanin Accumulation.

Glutathione S-transferases (GSTs) in plants are multipurpose enzymes that are involved in growth and development and anthocyanins transportation. However, members of the GST gene family were not identified in sweet cherry (). To identify the GST genes in sweet cherry, a genome-wide analysis was conducted.

Climatic suitability projection for deciduous fruit tree cultivation in main producing regions of northern China under climate warming.

China is the largest fruit producer and consumer market in the world. Understanding the growing conditions responses to climate change is the key to predict future site suitability of main cultivation areas for certain deciduous fruit trees. In this study, we used dynamic and growing degree day models driven by downscaled daily temperatures from 22 global climate models to project the effects of climate change on growing conditions for deciduous fruit trees under two representative concentration pathway (RCP) 4.

Evolutionary and Integrative Analysis of Gibberellin-Dioxygenase Gene Family and Their Expression Profile in Three Rosaceae Genomes (, , and ) Under Phytohormone Stress.

Cold induced genes (CIGs) regulate flower development and dormancy in Prunus avium L.

The flower buds continue to develop during the whole winter in tree fruit species, which is affected by environmental factors and hormones. However, little is known about the molecular mechanism of flower development during dormancy phase of sweet cherry in response to light, temperature and ABA. Therefore, we identified two cold induced gene (CIG) PavCIG1 and PavCIG2 from sweet cherry, which were closely to PpCBF and PyDREB from Prunus persica and Prunus yedoensis by using phylogenetic analysis, suggesting conserved functions with these evolutionarily closer DREB subfamily genes.
