The MYB (v-myb avian myeloblastosis viral oncogene homolog) transcription factor family plays an important role in plant growth, development, and response to biotic abiotic stresses. However, the gene functions of factors sweet potato (Ipomoea batatas (L.) Lam) have not been elucidated. In this study, gene, IbMYB308, was identified isolated from potato. Multiple sequence alignment showed that IbMYB308 is a typical R2R3-MYB factor. Further, quantitative real-time PCR (qRT-PCR) analysis revealed expressed root, stem, and, especially, leaf tissues. Moreover, it had tissue-specific profile. experiment also expression induced by different stresses (20% PEG-6000, 200 mM NaCl, 20% H2O2). After NaCl treatment, several stress-related genes (SOD, POD, APX, P5CS) upregulation transgenic plants, CAT activity, POD proline content, protein content tobacco increased, while MDA decreased. conclusion, study demonstrated could improve salt stress tolerance tobacco.

Long non-coding RNAs (lncRNAs) play important roles in response to biotic and abiotic stress through acting as competing endogenous (ceRNAs) decoy mature miRNAs. However, whether this mechanism is involved cotton salt remains unknown. We report the characterization of an lncRNA, lncRNA354, whose expression was reduced salt-treated localized at nucleus cytoplasm. Using target mimic (eTM) analysis, we predicted that lncRNA354 had a potential binding site for miR160b. Transient tobacco demonstrated miR160b eTM attenuated suppression its genes, including auxin factors (ARFs). Silencing or overexpressing affected ARFs. targets GhARF17/18 resulted taller plants enhanced resistant stress. Overexpression Arabidopsis led dwarf plants, decreased root dry weight tolerance. Our results show lncRNA354-miR160b effect on may modulate signalling thus affect growth. These also shed new light lncRNA-associated responses

Plant growth and development are greatly affected by the environment. Many genes have been identified to be involved in regulating plant adaption of abiotic stress. Apart from protein-coding genes, more evidence indicates that non-coding RNAs (ncRNAs), including small long ncRNAs (lncRNAs), can target developmental stress-responsive mRNAs, regulatory DNA regions, proteins regulate transcription various at transcriptional, posttranscriptional, epigenetic level. Currently, molecular mechanisms sRNAs lncRNAs controlling response being deeply explored. In this review, we summarize recent research progress plants, focusing on signal factors, expression characters, targets functions, interplay network their stress responses.

SUMMARY The cuticular wax layer on leaf surfaces limits non‐stomatal water loss to the atmosphere and protects against pathogen invasion. Although many genes associated with biosynthesis transport in plants have been identified, their regulatory mechanisms remain largely unknown. Here, we show that MYB transcription factor OsMYB60 positively regulates this helps rice ( Oryza sativa ) tolerate drought stress. Compared wild type japonica cultivar ‘Dongjin’), osmyb60 null mutants osmyb60‐1 osmyb60‐2 exhibited increased sensitivity, more chlorophyll leaching higher rates of loss. Quantitative reverse‐transcription PCR showed function led downregulation genes, leading reduced amounts total components under normal conditions. Yeast one‐hybrid, luciferase transient transcriptional activity, chromatin immunoprecipitation assays revealed directly binds promoter OsCER1 (a key gene involved very‐long‐chain alkane biosynthesis) upregulates its expression. Taken together, these results demonstrate enhances resilience stress by promoting surfaces.
