Advances in the omics research of Rosaceae

Ornamental Plant Research, Journal Year: 2024, Volume and Issue: 4(1), P. 0 - 0

Published: Jan. 1, 2024

Rosaceae plants are widely distributed worldwide. These plants, including well-known ornamental and those producing temperate fruits, have significant economic value. The utilization of omics technologies has significantly advanced the research progress on in various areas germplasm resources, molecular breeding, evolutionary domestication. Here, we provide an overview applications Rosaceae. It includes whole-genome sequencing assembly as well genome-wide association studies, transcriptome, proteomics, metabolomics, comparative genomics. techniques used to understand genetic regulatory mechanisms underlying important traits such flower color, fragrance, stress tolerance, fruit quality. We outline prospects genomics aiming establish a foundation for comprehending breeding traits. This could potentially theoretical support rapidly cultivating new varieties.

Identification and expression analysis of CCCH gene family and screening of key low temperature stress response gene CbuC3H24 and CbuC3H58 in Catalpa bungei

BMC Genomics, Journal Year: 2024, Volume and Issue: 25(1)

Published: Aug. 11, 2024

Catalpa bungei, a tree indigenous to China, is renowned for its superior timber quality and as an ornamental in horticulture. To promote the cultivation of C. bungei cold regions expand distribution, enhancing tolerance essential. The CCCH gene family widely involved plant growth, development, expression under stress conditions, including low-temperature stress. However, comprehensive identification analysis these genes have not yet been conducted. This study aims identify key cold-tolerance-related within providing necessary theoretical support expansion regions. In this study, 61 were identified characterized. Phylogenetic assessment divided into 9 subfamilies, with 55 members mapped across 16 chromosomes. structures protein motifs indicated that same subfamily shared similar exon/intron distribution motif patterns, supporting phylogenetic classification. Collinearity suggested segmental duplications played significant role family. Notably, RNA sequencing 4 °C conditions CbuC3H24 CbuC3H58 exhibiting most responses, highlighting their importance zinc finger response findings lay foundation further exploring mechanisms crucial insights

Low ground temperature is a major factor limiting overwintering in cucumber cultivation facilities northern alpine regions. Lower temperatures the root zone directly affect physiological function of system, which turn affects normal activity plants. However, importance has not attracted sufficient attention.

Physiological and Structural Changes in Apple Tree Branches of Different Varieties during Dormancy

Horticulturae, Journal Year: 2023, Volume and Issue: 9(8), P. 947 - 947

Published: Aug. 20, 2023

Low temperature is an abiotic stress factor limiting the distribution of fruit tree cultivation areas. As temperate deciduous trees, apple (Malus domestica) trees go dormant in winter to adapt or avoid damage caused by low temperatures. The capacity for cold resistance closely linked physiological, biochemical, and structural characteristics one-year-old branches. In this study, we investigated such changes branches cold-resistant ‘Hanfu’ (HF) cold-sensitive ‘Naganofuji 2’ (CF) varieties. relative electrical conductivity, malondialdehyde content, reactive oxygen species content HF were lower than those CF branches, while antioxidant enzyme activity was higher HF. proline, soluble protein, sugar contents both varieties showed initial increase, followed a subsequent decrease. Sucrose sorbitol main components, but sucrose fructose CF. periderm, phloem, xylem also found be thicker vessel diameter smaller density greater. results study provide theoretical reference further research on adaptability during dormancy.

Comprehensive insights into herbicide resistance mechanisms in weeds: a synergistic integration of transcriptomic and metabolomic analyses

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Oct. 11, 2023

Omics techniques, including genomics, transcriptomics, proteomics, and metabolomics have smoothed the researcher’s ability to generate hypotheses discover various agronomically relevant functions mechanisms, as well their implications associations. With a significant increase in number of cases with resistance multiple herbicide modes action, studies on are currently one predominant areas research within field weed science. High-throughput technologies already started revolutionizing current molecular biology studies. The evolution weeds (particularly via non-target site mechanism) is perfect example complex, multi-pathway integration-induced response. To date, functional transcriptomic metabolomic been used separately research, however there substantial lack integrated approach. Hence, despite omics provide insights into functioning weeds, using single can sometimes be misleading. This mini-review will aim discuss progress transcriptome-based metabolome-based approaches along systematic integration.
