Our previous study has shown that MAIGO2 (MAG2) is a subunit of the Golgi/endoplasmic reticulum (ER) multi-subunit tethering complex, and is required for tolerance to general osmotic stresses and abscisic acid and response to ER stress during seed germination and early growth. MAG2 is crucial for multi-environmental stress responses. To verify this hypothesis, the response of mag2 mutants to gibberellic acid (GA), sugar, and heat shock was described in this study. The mag2 mutants showed defects during seed germination and early seedling development under treatments with the GA biosynthesis inhibitor paclobutrazol, sucrose, and glucose. MAG2 is also essential for basal thermotolerance. However, the MAG2 homolog (MAG2L) is not necessary for these responses. MAG2 is an important regulator in the response to multi-environmental stimuli, supposedly through its roles in Golgi/ER retrograde trafficking and ER stress response.

To solve the problem of offshore oilfield development, based on the newly introduced pulsed neutron oxygen activation logging instrument, the application research of test design and interpretation method was carried out and applied to actual production. The structure, technical indicators and logging principles of pulsed neutron oxygen activation logging tools were introduced. The test design under different well conditions was studied, including general positive and negative injection, oil sleeve injection, single oil pipe configuration and multi-tubing configuration. A large amount of field test data was collected and analysed technically. A set of effective interpretation models was proposed. The corresponding interpretation software was developed. A set of test design methods and operating specifications for different well conditions were developed. Based on the conventional interpretation method, the peak selection, the double-tuber peak identification and the carbon dioxide f looding interpretation method were added. The results show that the test design and interpretation methods were applied well through a large number of field tests and production applications. Therefore, pulsed neutron oxygen activated injection profile logging technology is successfully applied in offshore oil fields

The triphenyl tetrazolium chloride (TTC) reduction assay was evaluated and improved with maize seed (Zea mays cv. Zhengdan958). The reduced TTC in embryo was extracted with three kinds of organic solvents: trichloroacetic acid (TCA)/acetone, ethanol, and acetone. The absorbance spectra of the three extracts were similar, with a maximum at 485 nm. The efficiency of TCA/acetone in extracting the reduced TTC was higher than that of acetone and ethanol. A negative correlation between TTC reduction and malondialdehyde content in embryo was demonstrated. The TCA/acetone extraction may be used as a routine protocol for TTC reduction assay of seed vigor in cereal (e.g. maize, rice, wheat and barley) seeds.

The digastricus and omohyoideus muscles are digastric muscles with two muscle bellies. An insertion tendon of the posterior belly becomes an intermediate tendon in digastricus muscles, whereas a single band-like muscle in omohyoideus muscles may later be interrupted by an intermediate tendon, possibly due to muscle cell death caused by mechanical stress. In human foetuses, an intermediate tendon provides the temporal origins of the tensor veli palatini and tensor tympani muscles. Some reptiles, including snakes, carry multiple series of digastric-like axial muscles, in which each intersegmental septum is likely to become an intermediate tendon. These findings indicate that many pathways are involved in the development of digastric muscles. A review of these morphologies suggested that the flexor digitorum superficialis (FDS) muscle was a digastric muscle, although the intermediate tendon may not be visible in the surface view in adults. The present observations support the hypothesis that the proximal anlage at the elbow develops into a deep muscle slip to a limited finger, while the distal anlage at the wrist develops into the other slips. The findings suggest that, in the FDS muscle, the proximal and distal bellies of the embryonic digastric muscle fuse together to form a laminar structure, in which muscle slips accumulate from the palmar to the deep side of the forearm.

The identification of proteins involved in pollen germination and tube growth is important for fundamental studies of fertility and reproduction in flowering plants. We used 2-DE and MALDI-TOF-MS to identify differentially expressed proteins in mature (P0) and 1-h germinated (P1) maize pollen. Among about 470 proteins separated in 2D gels, the abundances of 26 protein spots changed (up- or down-regulation) between P0 and P1. The 13 up-regulated protein spots were mainly involved in tube wall modification, actin cytoskeleton organization, energy metabolism, signaling, protein folding and degradation. In particular, pectin methylesterase, inorganic pyrophosphatase, glucose-1-phosphate uridylyltransferase and rab GDP dissociation inhibitor α are highly up-regulated, suggesting their potential role in pollen tube growth. The down-regulated 13 protein spots mainly include defense-related proteins, pollen allergens and some metabolic enzymes. This study would contribute to the understanding of the changes in protein expression associated with pollen tube development.

Background: Prenatal twisting of the femoral neck seems to result in an angle of anteversion or torsion, but the underlying process has not been elucidated. Materials and methods: This study analysed sagittal, frontal and horizontal sections of 34 embryo and foetal specimens of gestational age (GA) 6–16 weeks (crown-rump length 21–130 mm). At GA 6–7 weeks, the iliopsoas (IP) and gluteus medius (GME) muscles were inserted into the anterior and posterior aspects of the femur, respectively, allowing both insertions to be viewed in a single sagittal section. Results: At GA 8 weeks, the greater trochanter and the femoral neck angle became evident, and the GME tendon was inserted into the upper tip of the trochanter. At GA 9 weeks, the location of IP insertion was to the medial side of the GME insertion. After 9 weeks, the IP insertion consisted of a wavy, tendinous part of the psoas muscle and another part of the iliacus muscle, with many fibres of the latter muscle attached to the joint capsule. After GA 12 weeks, the IP was inserted into the anteromedial side of the greater trochanter, while the aponeurotic insertion of the GME wrapped around the trochanter. At GA 15–16 weeks, a deep flexion at the hip joint caused an alteration in the relative heights of the lesser and greater trochanter, with the former migrating from the inferior to the slightly superior side. Conclusions: These findings indicate that twisting of the femoral neck started at GA 8–9 weeks. (Folia Morphol 2019; 78, 2: 408–418)

The soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) play essential roles in intracellular trafficking. However, few experimental data have clarified their roles in the stress responses and the early secretary pathway in Arabidopsis. The AtSec20 gene encodes a protein that is homologous to yeast Sec20p and mammalian BNIP1, which are involved in the Golgi-to-ER retrograde trafficking in yeast and mammalian cells. In this study, AtSec20 is found to be required for the responses to salt stress, osmotic stress and gibberellin (GA) during seed germination and early seedling establishment. Mutation of AtSec20 unaffects the morphology of intracellular organelles, such as endoplasmic reticulum (ER), trans-Golgi network, and peroxisome, and vacuolar protein trafficking is normal in sec20 mutants. Collectively, these results imply that the AtSec20 is involved in abiotic stress tolerance, potentially via roles in retrograde vesicle fusion process in Arabidopsis.

Mitochondrial uncoupling proteins (UCPs) play crucial role in the regulation of metabolic thermogenesis, photosynthesis, redox poise, and response to stress situations. However, the involvements UCPs and its regulatory mechanisms in plant mitochondrial respiration and electron transport have not yet been fully substantiated. In this article, we show that UCP is essential for effective respiratory balance and mitochondrial electron transport poise under chilling stress in tomato. Compared with pTRV (non-silenced) plants, suppression of LeUCP the expression by virus-induced gene silencing significantly decreased the total, SHAM-resistant, and CN-resistant respiratory rates, but increased cytosolic glycolysis pathway- related gene expression and enzymes’ activities under chilling stress. The transcripts’ abundances of UCRH, COX1, COX2, AOX1a, AOX2, and NDC1 genes involved in main and bypass miETC components were decreased, while those of NDUO and SDH4 were slightly increased in the leaves of LeUCP-silenced plants. In addition, silencing of LeUCP aggravated H2O2 and O2- accumulation levels in leaves under chilling stress. Our results provide strong evidence that LeUCP is critical for respiratory homeostasis and mitochondrial electron transport signaling under chilling stress in tomato.
