“…The mechanisms of salt tolerance in halophytes have been gradually revealed over the past few years. The salt tolerance of a halophyte is determined by effective coordination between various physiological processes, metabolic pathways and gene networks under salt stress, including activation of antioxidant enzymes, induction and modulation of plant hormones, biosynthesis of compatible solutes and osmoprotectants, selective accumulation, exclusion of ions, and other mechanisms [15][16][17][18]. Furthermore, numerous genes that were isolated from halophytes have also been exploited by various modern biotechnological techniques to identify the genes that function in salt tolerance, including genes encoding for transcription factors [19,20], the Na + /H + antiporter gene [21,22] and genes encoding antioxidant enzymes [23,24].…”

Background Clerodendrum inerme (L.) Gaertn, a halophyte, usually grows on coastal beaches as an important mangrove plant. The salt-tolerant mechanisms and related genes of this species that respond to short-term salinity stress are unknown for us. The de novo transcriptome of C. inerme roots was analyzed using next-generation sequencing technology to identify genes involved in salt tolerance and to better understand the response mechanisms of C. inerme to salt stress. Results Illumina RNA-sequencing was performed on root samples treated with 400 mM NaCl for 0 h, 6 h, 24 h, and 72 h to investigate changes in C. inerme in response to salt stress. The de novo assembly identified 98,968 unigenes. Among these unigenes, 46,085 unigenes were annotated in the NCBI non-redundant protein sequences (NR) database, 34,756 sequences in the Swiss-Prot database and 43,113 unigenes in the evolutionary genealogy of genes: Non-supervised Orthologous Groups (eggNOG) database. 52 Gene Ontology (GO) terms and 31 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were matched to those unigenes. Most differentially expressed genes (DEGs) related to the GO terms “single-organism process”, “membrane” and “catalytic activity” were significantly enriched while numerous DEGs related to the plant hormone signal transduction pathway were also significantly enriched. The detection of relative expression levels of 9 candidate DEGs by qRT-PCR were basically consistent with fold changes in RNA sequencing analysis, demonstrating that transcriptome data can accurately reflect the response of C. inerme roots to salt stress. Conclusions This work revealed that the response of C. inerme roots to saline condition included significant alteration in response of the genes related to plant hormone signaling. Besides, our findings provide numerous salt-tolerant genes for further research to improve the salt tolerance of functional plants and will enhance research on salt-tolerant mechanisms of halophytes.

“…Permasalahan penting dalam budidaya tanaman jagung di lahan salin kawasan rawa pantai adalah keracunan Na + . Gharbi et al, 2017a;Zorb et al, 2019, mengemukakan cekaman Na + menyebabkan kerusakan sel tanaman dan defisit air sehingga pertumbuhan tanaman terhambat. Pada tanah salin, hambatan pertumbuhan semakin meningkat terutama pada kondisi air pasang dan musim kemarau, menyebabkan rendahnya kelarutan hara esensial sehingga terjadi kekahatan (Sahrawat, 2010;Haryoko et al, 2012).…”

Salt solubility is the abiotic pressure which has the most effect on the loss of plant quantity and quality. Salinity not only makes plants stressful but also presents severe constraints on crop production so an attempt to understand plant adaptation mechanisms is important for expanding agricultural production on saline soils. This study aimed to obtain a mechanism for the adaptation of hybrid and composites maize to NaCl stress through anion and cation absorption patterns. The experiments were carried out at the LLDikti Region X Laboratory from May to August 2016. The experiments were arranged in a factorial complete randomized design with three replications. The first factor was corn varieties, namely: hybrid corn (Pioneer 22 and Bisi 12), and composite corn (Bisma and Sukmaraga). The second factor was level of NaCl, namely: 0.0 mg kg-1 NaCl pH 5.0, and 4,000 mg kg-1 NaCl pH 5.0. Measurement of anions and cations using Spectroquant Thermoreator TR Nova 420. The adaptability of hybrid maize and composites to NaCl stress occurred through the mechanism of anion absorption and cation metabolism. The difference in the percentage of NO3-, NO2-, PO4-, NH4+, and K+ levels between hybrid maize varieties and composites showed a difference in the adaptation ability of maize varieties to salinity stress.

Increased production, many face increasingly complex challenges. The problem, which is not less important is the limited rice varieties tolerant to iron stress. The aim of the study was to obtain growth and distribution patterns of Fe2+ ions in several hybrid rice varieties. Experiment in Koto Baru, Sitiung I, Dharmasraya Regency, West Sumatra. The experiment used a completely randomized design, with five replications. The single factor is rice varieties, namely: Mekongga, Inpari 24, Inpari 27 and Inpari 28. The paddy fields used contain 104.69 mg kg-1 Fe2+, these concentrations greatly affect growth which causes poisoning. The production of milled dry grain in all varieties remained high even though it was iron-strapped, because the number of productive tillers formed in the SBSU system was more than 21 stems per clump, with production of grain weight > 5.4 Mg ha-1. The pattern of iron distribution occurs through absorption and translocation in the vegetative and generative phases to roots, stems, leaves, grain, and rice. The difference in iron levels in each part shows the ability of each variety to adapt. To obtain rice grains rich in iron and able to grow and produce well in iron-clamped conditions, it is recommended that aquaculture using the SBSU system with Inpari 27 varieties be able to produce iron content in rice grains of more than 27 mg kg-1 with production of grain weight 6.83 Mg ha-1.
