“…ABA signaling pathway cross talks with SA and JA defense hormone pathways, implying ABA is also involved in regulating plant disease resistance (Anderson et al, 2004;Berens et al, 2017). This is evidenced by several studies, for example, spraying 100 μM of exogenous ABA induced expression levels of PR4 and PR10 genes in lentil seedlings (Ford et al, 2017). Additionally, ABA hormone can modulate rice MAPK5 gene and protein biosynthesis, influencing downstream signaling processes of both disease resistance and abiotic stress tolerance (Xiong & Yang, 2003).…”

Cannabis sativa L. has been widely grown for millennia, serving humankind with a range of benefits (Chandra, Lata, et al., 2017).There are two major C. sativa varieties, medicinal cannabis and industrial hemp, which are differentiated by the amount of tetrahydrocannabinol (THC) content in plant dry weight. Medicinal cannabis (high-THC cannabis) is used for treating inflammation, seizure, nausea, vomiting and spasticity (Slawek et al., 2022). Industrial hemp (low-THC cannabis) has a robust fiber, used for making cloth, textiles, rope, yarn, paper and building blocks (Zimniewska, 2022).Additionally, hemp seed is consumed as a food supplement due to

Fungal pathogens pose a major threat toCannabis sativaproduction, requiring safe and effective management procedures to control disease. Chitin and chitosan are natural molecules that elicit plant defense responses. Investigation of their effects onC. sativawill advance understanding of plant responses towards elicitors and provide a potential pathway to enhance plant resistance against diseases. Plants were grown in thein vitroRoot-TRAPR system and treated with colloidal chitin and chitosan. Plant morphology was monitored, then plant tissues and exudates were collected for enzymatic activity assays, phytohormone quantification, qPCR analysis and proteomics profiling. Chitosan treatments showed increased total chitinase activity and expression of pathogenesis-related (PR) genes by 3-5 times in the root tissues. In the exudates, total peroxidase and chitinase activities and levels of defense proteins such as PR protein 1 and endochitinase 2 were increased. Shoot development was unaffected, but root development was inhibited after chitosan exposure. No significant effects on plant defense were observed upon chitin treatment. These results indicate that colloidal chitosan significantly promoted production and secretion of plant defense proteins inC. sativaroot system and could be used as a potential elicitor, particularly in hydroponic scenarios to manage crop diseases.

“…Finally, in many important plant pathological systems, phytohormones are essential for the activation of signaling during disease defense responses [ 103 , 104 , 105 , 106 , 107 ]. PR4 and PR10 were significantly upregulated in both the leaf and stem tissues of highly resistant lentil varieties after treatment with ABA, suggesting that ABA is a key hormonal activator of necrotrophic fungal defense response signaling in lentil [ 108 ]. Several PR10 genes are also induced by ABA [ 50 , 109 ].…”

The AP2/ERF GmERF113 Positively Regulates the Drought Response by Activating GmPR10-1 in Soybean

Ethylene response factors (ERFs) are involved in biotic and abiotic stress; however, the drought resistance mechanisms of many ERFs in soybeans have not been resolved. Previously, we proved that GmERF113 enhances resistance to the pathogen Phytophthora sojae in soybean. Here, we determined that GmERF113 is induced by 20% PEG-6000. Compared to the wild-type plants, soybean plants overexpressing GmERF113 (GmERF113-OE) displayed increased drought tolerance which was characterized by milder leaf wilting, less water loss from detached leaves, smaller stomatal aperture, lower Malondialdehyde (MDA) content, increased proline accumulation, and higher Superoxide dismutase (SOD) and Peroxidase (POD) activities under drought stress, whereas plants with GmERF113 silenced through RNA interference were the opposite. Chromatin immunoprecipitation and dual effector-reporter assays showed that GmERF113 binds to the GCC-box in the GmPR10-1 promoter, activating GmPR10-1 expression directly. Overexpressing GmPR10-1 improved drought resistance in the composite soybean plants with transgenic hairy roots. RNA-seq analysis revealed that GmERF113 downregulates abscisic acid 8′-hydroxylase 3 (GmABA8’-OH 3) and upregulates various drought-related genes. Overexpressing GmERF113 and GmPR10-1 increased the abscisic acid (ABA) content and reduced the expression of GmABA8’-OH3 in transgenic soybean plants and hairy roots, respectively. These results reveal that the GmERF113-GmPR10-1 pathway improves drought resistance and affects the ABA content in soybean, providing a theoretical basis for the molecular breeding of drought-tolerant soybean.
