Frontiers in Genetics, Journal Year: 2022, Volume and Issue: 13

Published: Aug. 9, 2022

More than a half-century has passed since it was discovered that phytohormone cytokinin (CK) is essential to drive cytokinesis and proliferation in plant tissue culture. Thereafter, emerged as the primary regulator of cell cycle numerous developmental processes. Lately, growing body evidence suggests role mitigating both abiotic biotic stress. Cytokinin defend plants against excessive light exposure unique kind stress generated by an altered photoperiod. Secondly, also exhibits multi-stress resilience under changing environments. Furthermore, homeostasis affected several forms Therefore, diverse roles reaction stress, well its interactions with other hormones, are discussed detail. When comes agriculture, understanding functioning processes cytokinins environmental conditions can assist utilizing phytohormone, increase productivity. Through this review, we briefly describe biological enhancing performance growth challenges probable mechanisms underpinning cytokinin-induced tolerance. In addition, article lays forth strategy for using biotechnological tools modify genes pathway engineer tolerance plants. The information presented here will better function their effective investigation cropping system.

Friends in Arms: Flavonoids and the Auxin/Cytokinin Balance in Terrestrialization

Plants, Journal Year: 2023, Volume and Issue: 12(3), P. 517 - 517

Published: Jan. 23, 2023

Land plants survive the challenges of new environments by evolving mechanisms that protect them from excess irradiation, nutrient deficiency, and temperature water availability fluctuations. One such evolved mechanism is regulation shoot/root growth ratio in response to balancing actions hormones auxin cytokinin. Plant terrestrialization co-occurred with a dramatic expansion secondary metabolism, particularly evolution establishment flavonoid biosynthetic pathway. Flavonoid biosynthesis responsive wide range stresses, numerous synthesized species offer two main evolutionary advantages land plants. First, flavonoids are antioxidants thus defend against those adverse conditions lead overproduction reactive oxygen species. Second, aid protecting deficiency modulating root development establishing symbiotic relations beneficial soil fungi bacteria. Here, we review different aspects relationships between auxin/cytokinin module flavonoids. The current body knowledge suggests whereas both cytokinin regulate biosynthesis, act fine-tune only auxin, which turn regulates action. This conclusion agrees established master regulatory function controlling ratio.

MicroRNA: A Dynamic Player from Signalling to Abiotic Tolerance in Plants

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(14), P. 11364 - 11364

Published: July 12, 2023

MicroRNAs (miRNAs) are a class of non-coding single-stranded RNA molecules composed approximately 20–24 nucleotides in plants. They play an important regulatory role plant growth and development as signal abiotic tolerance. Some stresses include drought, salt, cold, high temperature, heavy metals nutritional elements. miRNAs affect gene expression by manipulating the cleavage, translational or DNA methylation target messenger RNAs (mRNAs). This review describes current progress field considering two aspects: (i) way produced regulated (ii) miRNA/target genes used responses to various stresses. Studying molecular mechanism action miRNAs’ downstream could optimize genetic manipulation crop conditions provide more theoretically optimized basis for improving production. MicroRNA is novel signalling interplant communication relating

CRISPR-mediated promoter editing of a cis-regulatory element of OsNAS2 increases Zn uptake/translocation and plant yield in rice

Frontiers in Genome Editing, Journal Year: 2024, Volume and Issue: 5

Published: Jan. 23, 2024

Developing nutritious rice with a higher yield is one approach to alleviating the problem of micronutrient deficiency in developing countries, especially human malnutrition involving zinc and iron (Fe) deficiency, achieving better adoption. The transport micronutrients such as Fe Zn mainly regulated via nicotianamine synthase ( OsNAS ) gene family, whereas complex trait that involves multiple loci. Genome editing CRISPR (clustered regularly interspaced short palindromic repeat)-Cas9, focusing on OsNAS2 promoter, particularly deletion cis -regulatory element ARR1AT at position −933, was conducted for an enhanced accumulation grain per plant. results showed our promoter increased concentration Evidence also improved spikelet number main panicle led traits were inherited “transgene-free” homozygous plant progenies. Further investigation needs be validate performance under field conditions elucidate cause increase.
