Rice tillering determines grain yield, yet the molecular regulatory network is still limited. In this study, we demonstrated that the transcription factor OsMADS60 promotes the expression of the auxin transporter OsPIN5b to affect auxin distribution and inhibit rice tillering and grain yield. Natural variation was observed in the promoter region of OsMADS60, with its expression level negatively correlated with tiller number and inducible by auxin.

The widely distributed heat shock protein DnaJ is renowned for its pivotal role in enhancing thermal tolerance in plants; however, its involvement in drought tolerance remains elusive. In this study, genes encoding DnaJ1 were cloned from drought-resistant wild tomato (Solanum pennellii) and drought-sensitive cultivated tomato (Solanum lycopersicum). SpDnaJ1 and SlDnaJ1 from both tomato species were localized in the chloroplast, and their gene expression was induced by various abiotic stresses.

College of Horticulture and Gardening, Yangtze University, Jingzhou 434025, Hubei, China.
Efforts to protect germplasm resources of Fraxinus hupehensis (Oleaceae), an endangered species endemic to Dahong Mountain, Hubei Province, China, are facing difficulties due to the deep dormancy of its seeds. To elucidate the molecular regulatory networks underlying dormancy release, an integrated investigation combining physiological profiling with transcriptomic and metabolomic analyses was performed on seeds of F. hupehensis during six critical germination stages.

Materials And Methods: Serum iodine (I), selenium (Se), and zinc (Zn) concentrations were measured using inductively coupled plasma ionization tandem mass spectrometry (Agilent 8900 ICP-MS Triple Quad); by chemiluminescent immunoassay on an automatic analyzer Architect i2000 - TSH and AT-TPO in blood serum; by enzyme immunoassay - ZnT8A; biochemical method - ALP, SOD1 in 1150 people aged from 18 to 65 years (the average age of the subjects was 40±5 years). Ultrasound of the thyroid gland was performed in the supine position using a portable ultrasound machine LOGIQe with a multifrequency linear sensor 10-15 MHz; during the study, the volume of the thyroid gland, the presence of nodules and their characteristics according to the TIRADS classification, the structure of the thyroid gland and its echogenicity were assessed.
