“…Under drought stress, starch granules are hydrolysed to release energy to supplement the insufficient energy supply caused by photosynthesis damage under stress. Meanwhile, the hydrolysed starch granules can increase the concentration of cell fluid and osmotic pressure to ensure the normal absorption of cell water to alleviate the drought (Pang et al 2020). In this study, the wheat chloroplasts had almost had no starch granule accumulation under drought treatment, which is consistent with previous net photosynthetic rate results (Wang et al 2018).…”

5-Aminolevulinic acid (ALA), as a precursor of plant chlorophyll synthesis, can alleviate damage to photosynthesis and thus improve the drought resistance of plants, but the mechanism behind this is still obscure, especially its correlation with functional gene transcription and noncoding RNA regulation. The leaves were collected from Aikang-58 wheat seedlings subjected to drought stress and exogenous ALA application for ultrastructure observation and gene transcription analysis. The results indicated that drought stress attenuated the photosynthesis evidenced by the decrease of net photosynthetic rate (P n ) and stomatal conductance (g s ), damaged the chloroplast ultrastructure by destroying the thylakoid matrix, degrading the chlorophyll, and leading to lipid peroxidation of the cells due to the toxicity of free radicals, causing lipids to dissociate and combine with osmium acid to form plastoglobuli. Under drought stress, exogenous ALA pretreatment can increase the transcript abundance of the chlorophyll synthesis-related genes. Moreover, exogenous ALA increased psb28 transcript abundance under drought stress, to alleviate the damage to the chloroplast ultrastructure and photosynthesis. Our data revealed the possible gene transcriptional regulation patterns in response to drought stress and exogenous ALA alleviation.

“…Plants organize structure and function to adapt in most cases without causing permanent harm to different environmental stress conditions [12]. To withstand the complex physiological reactions that control drought stress, photosynthetic pigments efficiency was stimulated, and plant growth survival was promoted [13,14]. The net photosynthetic rate and chlorophyll content decreased in drought stress conditions due to decreased stomatal conductance, as stomatal closure is one of the first responses to drought stress [15].…”

Background Melatonin played an essential role in numerous vital life processes of animals and captured the interests of plant biologists because of its potent role in plants as well. As far as its possible contribution to photoperiodic processes, melatonin is believed to act as a growth regulator and a direct free radical scavenger/indirect antioxidant. The objective of this study to identify a precise melatonin concentration for a particular application method to improve plant growth requires identification and clarification. Methods This work establishes unique findings by optimizing melatonin concentration in alleviating the detrimental effects of drought stress in maize. Maize plants were subjected to drought stress (40–45% FC) after treatments of melatonin soil drenching at different concentrations (50, 100, and 150 µM) to consider the changes of growth attribute, chlorophyll contents, photosynthetic rate, relative water content (RWC), chloroplast ultrastructure, endogenous hormonal mechanism, and grain yield. Results Our results showed that the application of melatonin treatments remarkably improved the plant growth attributes, chlorophyll contents, photosynthetic rate, RWC, hormonal mechanism, and grain yield plant−1 under drought conditions at a variable rate. Conclusion Our current findings hereby confirmed the mitigating potential of melatonin application 100 µM for drought stress by maintaining plant growth, hormone content, and grain yield of maize. We conclude that the application of melatonin to maize is effective in reducing drought stress tolerance. Graphical Abstract

“…The need to reduce soil erosion and increase community diversity has increased the demand for adaptable plant species as pioneer plants [2]. Therefore, considerable attention on exploring and selecting the ideal adaptable plant species due to their environmental adaptability such as higher productive forces, better resistance to adversity [3][4][5][6][7][8]. Although, abound of plants have been studies and used for ecological restoration, the ideal adaptable plant species source for ecological restoration of rocky desertification should consider environmental, plant species characteristics aspects [9][10][11][12][13].…”

In order to obtain the genetic basis of transcriptome data of Orychophragmus violaceus seedlings, the transcriptome of Orychophragmus violaceus was paired-end sequenced by Illumina Novaseq 6000 platform, a total of 59174171 clean reads (17.75 Gb clean bases) were obtained, and 110919 unigenes were obtained after assembly by de novo, with the longest and shortest length of 15030, 301 bp and an average length of 784 bp. The N50 was 947 bp and the N90 was 396 bp. These unigenes were compared among seven public databases including Non-redundant protein sequences (NR), Nucleotide (NT), Swiss-prot protein database (Swiss-Prot), Protein family (Pfam), Eu-karyotic ortholog groups (KOG), Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG), as a result of 75369 (67.94%), 69004 (62.21%), 62258 (56.12%), 56068 (50.54%), 27796 (25.05%), 56066 (50.54%), 32897 (29.65%) unigenes were annotated respectively. These annotation results showed that Orychophragmus violaceus had most homologous sequences with 13610 unigenes with Quercus suber. The GO annotations showed that 56066 unigenes were annotated with 219038, which were divided into 3 categories and 43 functional groups. The KOG annotations showed that 27796 unigenes were annotated and grouped into 25 functional categories. The KEGG annotations showed that 32897 unigenes were involved in 34 types of metabolic pathways and 305 metabolic pathway branches. A total of 18118 SSR sites and 112584 CDS sequences were detected according to analyzing the coding sequences and microsatellite. Base on the high-throughput transcriptome sequencing of Orychophragmus violaceus, with a large number of functional genes are excavated, which provide certain basic data support for the subsequent development of bioinformatics analysis such as molecular markers and functional metabolic pathways.
