“…These genes participate in the metabolic process of carbohydrates, increasing the content of soluble sugars in leaves and therefore providing nutrients and energy for plant growth, development and flowering. Additionally, nitrogen sources are thought to play a crucial role in plant developmental processes, including the regulation of flowering time (Zhang et al, 2021;Zhang et al, 2023). Our study showed that the CEPRECEPTOR1 (CEPR1) gene, which is involved in nitrate absorption and signal transduction (Ota et al, 2020;Taleski et al, 2020), was downregulated and reduced nitrogen source substances in oat, resulting in early flowering under a long-day photoperiod.…”

Proper flowering is essential for the reproduction of all kinds of plants. Oat is an important cereal and forage crop; however, its cultivation is limited because it is a long-day plant. The molecular mechanism by which oats respond to different photoperiods is still unclear. In this study, oat plants were treated under long-day and short-day photoperiods for 10 days, 15 days, 20 days, 25 days, 30 days, 40 days and 50 days, respectively. Under the long-day treatment, oats entered the reproductive stage, while oats remained vegetative under the short-day treatment. Forty-two samples were subjected to RNA-Seq to compare the gene expression patterns of oat under long- and short-day photoperiods. A total of 634-5,974 differentially expressed genes (DEGs) were identified for each time point, while the floral organ primordium differentiation stage showed the largest number of DEGs, and the spikelet differentiation stage showed the smallest number. Gene Ontology (GO) analysis showed that the plant hormone signaling transduction and hormone metabolism processes significantly changed in the photoperiod regulation of flowering time in oat. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Mapman analysis revealed that the DEGs were mainly concentrated in the circadian rhythm, protein antenna pathways and sucrose metabolism process. Additionally, transcription factors (TFs) involved in various flowering pathways were explored. Combining all this information, we established a molecular model of oat flowering induced by a long-day photoperiod. Taken together, the long-day photoperiod has a large effect at both the morphological and transcriptomic levels, and these responses ultimately promote flowering in oat. Our findings expand the understanding of oat as a long-day plant, and the explored genes could be used in molecular breeding to help break its cultivation limitations in the future.

“…Fertilizers and plant nutrient solutions are applied as a common practice to alleviate abiotic stress and enhance crop yield [ 3 , 8 , 9 ]. Recently, nutrient deficiency (references in [ 10 , 11 , 12 ]), imbalance of nutrients [ 13 , 14 , 15 , 16 ], and heavy metal accumulation in soil [ 17 , 18 ] have been reported to influence flowering time [ 8 ], leading to altered plant growth.…”

“…Previously, NPK fertilizers have been used to control flowering time in crop plants [ 19 , 20 ]. A recent study documented the process of how major nutrient elements influence flowering time and the genes involved in NPK nutrient-mediated regulation of flowering time [ 10 ]. Largely, loss of function of genes encoding nutrient transporter proteins localized in the plasma membrane or subcellular organelles and signaling genes involved in nutrient assimilation, consequently responsible for nutrient (N, P, and K) deficiency, are reported to induce flowering [ 10 ].…”

Flowering time in plants is a complex process regulated by environmental conditions such as photoperiod and temperature, as well as nutrient conditions. While the impact of major nutrients like nitrogen, phosphorus, and potassium on flowering time has been well recognized, the significance of micronutrient imbalances and their deficiencies should not be neglected because they affect the floral transition from the vegetative stage to the reproductive stage. The secondary major nutrients such as calcium, magnesium, and sulfur participate in various aspects of flowering. Micronutrients such as boron, zinc, iron, and copper play crucial roles in enzymatic reactions and hormone biosynthesis, affecting flower development and reproduction as well. The current review comprehensively explores the interplay between microelements and flowering time, and summarizes the underlying mechanism in plants. Consequently, a better understanding of the interplay between microelements and flowering time will provide clues to reveal the roles of microelements in regulating flowering time and to improve crop reproduction in plant industries.

Climate change cause a temperature increase, decreasing soil fertility and causing a reduced microbial and nutrient availability, and increased salinization, so it cannot support the growth of soybean plants. Soybeans are vulnerable to climate change, which can lead to lower yields. Biochar is an organic material that can improve soil's physical, chemical, and biological fertility. This study aims to obtain soybean varieties and biochar types that increase growth and yield in low soil fertility cultivation. This research was conducted in August 2022 – June 2023 at the Agricultural Faculty Experimental Field of Universitas Sebelas Maret. The research was designed in randomized complete block design factorial with three replications. The first factor was soybean varieties, and the second factor was types of biochar. Data analyzed using analysis of variance (ANOVA), followed by DMRT 5% if there was a significant difference. The results showed that Demas 1 variety significantly affects growth and yield with biochar addition compared to Dena 1 and Gepak Kuning. The addition of rice husk biochar can increase the growth and yield of 3 soybean varieties, compared to the addition of sugar palm fiber biochar and without the addition of biochar.
