[PMID: 39952161 DOI: 10.1016/j.plaphy.2025.109634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 02/06/2025] [Accepted: 02/09/2025] [Indexed: 02/17/2025]
Abstract
The FOREVER YOUNG FLOWER (FYF/AGL42) gene plays an important role in regulating the flower development especially the flowering time, and senescence and abscission of floral organs. Melon is an important horticultural crop, and the flower development has an important influence on pollination, fertilization and final fruit yield. However, the function of FYF homolog is still unknown in melon. In this study, the characteristic of melon CmFYF was analyzed combining with molecular biology, developmental biology and biochemical tools. CmFYF was present in all detected tissues of melon, but its expression level was significantly higher in shoot apex of lateral branches and male flowers than that in other tissues. Subcellular localization revealed that CmFYF was located in the nucleus. CmFYF was able to respond to multiple hormone and environmental signals including GA3, SA, MeJA, cold and drought. Ectopic expression of CmFYF in Arabidopsis resulted in the early flowering phenotype and increased plant height, but had no effect on the flower organs or fruits development. In melon, overexpression of CmFYF increased the number of male flowers, but inhibited the size of fruit. These results suggested that CmFYF of melon was partially equivalent to AtFYF of Arabidopsis. Further biochemical analyses indicated that CmFYF directly interacted with CmAGb (a homolog of Arabidopsis AGAMOUS), CmKNAT7 (KNOTTED-LIKE HOMEOBOX OF ARABIDOPSIS THALIANA 7) and itself at the protein level. Therefore, this study enriched the function of FYF homologs and revealed a preliminary molecular mechanism underlying the male flower production and fruit development in melon.

Improving Rice Quality by Regulating the Heading Dates of Rice Varieties without Yield Penalties. PLANTS (BASEL, SWITZERLAND) 2024; 13:2221. [PMID: 39204657 PMCID: PMC11360702 DOI: 10.3390/plants13162221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Revised: 07/25/2024] [Accepted: 08/08/2024] [Indexed: 09/04/2024]
Abstract
The heading date, a critical trait influencing the rice yield and quality, has always been a hot topic in breeding research. Appropriately delaying the flowering time of excellent northern rice varieties is of great significance for improving yields and enhancing regional adaptability during the process for introducing varieties from north to south. In this study, genes influencing the heading date were identified through genome-wide association studies (GWAS). Using KenDao 12 (K12), an excellent cultivar from northern China, as the material, the specific flowering activator, OsMADS50, was edited using the genome-editing method to regulate the heading date to adapt to the southern planting environment. The results indicated that the osmads50 mutant line of K12 flowered about a week later, with a slight increase in the yield and good adaptability in the southern region in China. Additionally, the expressions of key flowering regulatory genes, such as Hd1, Ghd7, Ehd1, Hd3a, and RFT1, were reduced in the mutant plants, corroborating the delayed flowering phenotype. Yield trait analysis revealed that the primary factor for improved yield was an increase in the number of effective tillers, although there is potential for further enhancements in the seed-setting rate and grain plumpness. Furthermore, there were significant increases in the length-to-width ratio of the rice grains, fat content, and seed transparency, all contributing to an overall improvement in the rice quality. In summary, this study successfully obtained a rice variety with a delayed growth period through OsMADS50 gene editing, effectively implementing the strategy for adapting northern rice varieties to southern climates. This achievement significantly supports efforts to enhance the rice yield and quality as well as to optimize production management practices.

[PMID: 38203405 PMCID: PMC10778694 DOI: 10.3390/ijms25010235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 12/17/2023] [Accepted: 12/20/2023] [Indexed: 01/12/2024] Open
Abstract
Cotton growth and yield are severely affected by abiotic stress worldwide. Mepiquate chloride (MC) and melatonin (MT) enhance crop growth and yield by reducing the negative effects of abiotic stress on various crops. Numerous studies have shown the pivotal role of MC and MT in regulating agricultural growth and yield. Nevertheless, an in-depth review of the prominent performance of these two hormones in controlling plant morpho-physiological activity and yield in cotton under abiotic stress still needs to be documented. This review highlights the effects of MC and MT on cotton morpho-physiological and biochemical activities; their biosynthetic, signaling, and transduction pathways; and yield under abiotic stress. Furthermore, we also describe some genes whose expressions are affected by these hormones when cotton plants are exposed to abiotic stress. The present review demonstrates that MC and MT alleviate the negative effects of abiotic stress in cotton and increase yield by improving its morpho-physiological and biochemical activities, such as cell enlargement; net photosynthesis activity; cytokinin contents; and the expression of antioxidant enzymes such as catalase, peroxidase, and superoxide dismutase. MT delays the expression of NCED1 and NCED2 genes involved in leaf senescence by decreasing the expression of ABA-biosynthesis genes and increasing the expression of the GhYUC5, GhGA3ox2, and GhIPT2 genes involved in indole-3-acetic acid, gibberellin, and cytokinin biosynthesis. Likewise, MC promotes lateral root formation by activating GA20x genes involved in gibberellin catabolism. Overall, MC and MT improve cotton's physiological activity and antioxidant capacity and, as a result, improve the ability of the plant to resist abiotic stress. The main purpose of this review is to present an in-depth analysis of the performance of MC and MT under abiotic stress, which might help to better understand how these two hormones regulate cotton growth and productivity.

Int J Mol Sci 2023; 24:ijms24119517. [PMID: 37298464 DOI: 10.3390/ijms24119517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 05/19/2023] [Accepted: 05/25/2023] [Indexed: 06/12/2023] Open
Abstract
Salinity is a major abiotic stress that restricts cotton growth and affects fiber yield and quality. Although studies on salt tolerance have achieved great progress in cotton since the completion of cotton genome sequencing, knowledge about how cotton copes with salt stress is still scant. S-adenosylmethionine (SAM) plays important roles in many organelles with the help of the SAM transporter, and it is also a synthetic precursor for substances such as ethylene (ET), polyamines (PAs), betaine, and lignin, which often accumulate in plants in response to stresses. This review focused on the biosynthesis and signal transduction pathways of ET and PAs. The current progress of ET and PAs in regulating plant growth and development under salt stress has been summarized. Moreover, we verified the function of a cotton SAM transporter and suggested that it can regulate salt stress response in cotton. At last, an improved regulatory pathway of ET and PAs under salt stress in cotton is proposed for the breeding of salt-tolerant varieties.
