Transcriptomic Insights into Exogenous Putrescine-Mediated Cold Adaptation in Cannabis sativa L. [miRNA-Seq]

ABSTRACT: Low temperature is a major abiotic stress factor that promotes oxidative stress and disrupts cellular homeostasis, ultimately impairing plant physiological functions. This study investigated the effects of exogenous putrescine treatment on the cold stress response of Cannabis sativa L. This in silico transcriptome analysis demonstrated that putrescine mediates cold stress tolerance in C. sativa, providing valuable insight for future in vitro validation studies and a foundational framework for the development of cold-resistant hemp cultivars.

Transcriptome Response of Leaves from Young Cannabis sativa L. under Heat Stress

Project description:Cannabis sativa L. is a dioecious, annual herbaceous crop (2n = 20) known for its diverse applications across textile, food, cosmetic, and medicinal industries. Recent increases in global temperatures have raised concerns about the impact of heat stress on hemp physiology. Although previous studies have demonstrated reductions in photosynthetic efficiency and cannabinoid levels under heat stress, transcriptome-wide insights into molecular responses remain limited. In this study, we performed a genome-wide transcriptomic analysis to investigate the molecular mechanisms of heat stress response in C. sativa cv. Pink Pepper. This dataset provides a high-resolution transcriptomic resource to explore thermotolerance in C. sativa and contributes to a better understanding of its molecular adaptation to heat stress. The findings can aid future breeding and biotechnology efforts aimed at enhancing stress resilience in hemp.

In silico gene expression profiling of Cannabis sativa

Project description:Even if a large amount of high-throughput functional genomic data exists, most researchers feature a strong background in molecular biology but lack advanced bioinformatics skills. In this work, publicly available gene expression datasets have been analyzed giving rise to a total of 40,224 gene expression profiles within different Cannabis tissues/developmental stages. The resource here proposed will provide researchers with a starting point for future investigations of Cannabis sativa.

Whole genome-wide expression profiles of hemp (Cannabis sativa L.) in response to drought stress

Project description:Drought stress is the main environmental factor influencing hemp growth and yield. However, little is known about the response mechanism of hemp to drought stress. A total of 44.10 M tags and 8.91G bases were sequenced in the control hemp (CK) and drought stress hemp (DS) libraries. A total of 1292 differentially expressed genes (DEGs), including 883 up-regulated genes and 409 down-regulated genes, were identified. These results may contribute toward improving our understanding about the drought stress regulatory mechanism of hemp, and improving its drought tolerance ability.

Transcriptomic Responses of Cannabis sativa L. to Trichoderma hamatum Treated under Drought Conditions

Project description:Cannabis sativa L., which has been reclassified as an agronomic crop, has experienced an increase in cultivation. Its interactions with a variety of environmental stressors have been extensively studied. However, the mechanisms of recovery through fungal associations remain underexplored. Trichoderma hamatum, known for its role as a biological agent, enhances plant growth and provides antagonistic defense against pathogenic microbes. This meta-dataset aims to investigate whether Th can enhance drought resistance in a Cannabis plants.

Transcription profiling of three developmental stages of the outer layer of hemp (Cannabis sativa) stems

Project description:Three 2cm segments were excised from different parts (TOP, MID, BOT) along the vertical axis of a 4 week old stem of hemp (C. sativa), and the outer layers of the stem were compared using a cDNA amplicon array. Each segment represented a different developmental stage, especially in relation to bast fibre differentiation (i.e. TOP= elongation, MID=transition, BOT= thickening). Only the cDNAs that showed the highest differential expression were sequenced.
