“…In our study, the expression of cytokinins supports the possibility that they are involved in signaling defense responses after a pathogen attack, improving the resistance to pathogens [70].…”

Abstract:Forests are essential resources on a global scale, not only for the ecological benefits, but also for economical and landscape purposes. However, in recent years, a large number of forest species have suffered a serious decline, with maritime pine being one of the most affected. In Portugal, the maritime pine forest has been devastated by the pine wood nematode (PWN), the causal agent of pine wilt disease. In this study, RNA-Seq data was used to characterize the maritime pine response to infection with PWN, by determining the differentially expressed genes and identifying the regulatory networks and pathways associated. The analyses showed clear differences between an early response that occurs immediately after inoculation and a late response that is observed seven days after inoculation. Moreover, differentially expressed genes related to secondary metabolism, oxidative stress and defense against pathogen infection were identified over different time points. These results provide new insights about the molecular mechanisms and metabolic pathways involved in the response of Pinus pinaster against PWN infection, which will be a useful resource in follow-up studies and for future breeding programs to select plants with lower susceptibility to this disease.

“…Cytokinins have functions many physiological processes in plants, including stimulation of cell division, differentiation and growth, the promotion of biogenesis and chloroplast differentiation, the regulation of seed dormancy and germination, impediment of the leaf senescence, the formation of shoots from calluses in a culture, and inhibition of the root apical meristem. Moreover, CKs facilitate the assimilation of nutrition [74], the formation of nitrogen-fixing nodules [75], tolerances to adverse environments [76], and the improvement of the quantity and quality of crop plants [77]. It has also been uncovered that CKs play a key role in biological processes of microalgae including the induction of cell division, the stimulation of growth processes, and the augmentation of photosynthetic activity.…”

Phytohormones and Effects on Growth and Metabolites of Microalgae: A Review

et al. 2018

Microalgae cultivation is booming in agriculture, aquaculture, and bioenergy sectors. A wide range of bioactive compounds with attractive properties can be produced with microalgae, including pigments, vitamins, proteins, carbohydrates, and lipids. The biofuel yields from microalgae can exceed the yields obtained with energy crops by 10-100 times. Therefore, such cultivation is promising for the regulation of the biosynthesis of microalagae with phytohormones, which can enhance the production of high-valued bioproducts. This review reports the effect of auxins, abscisic acid, cytokinins, gibberellins, and ethylene on microalgal growth and metabolites, as well as the crosstalk of different phytohormones. The use of phytohormones is also promising because it can also reduce the inputs necessary to grow the selected microalgae and maximize the yields.

“…They are also involved in abiotic stresses [20] such as salinity [21] and drought [19]. They are also important for various crop traits such as productivity and enhanced stress tolerance [3,22]. CKs also release seeds from dormancy [18] and are considered as abscisic acid antagonists [23].…”
