The bacterial leaf blight in rice caused by Xanthomonas oryzae pv. oryzae (Xoo) affects crop losses worldwide. In spite of developing resistant varieties by introgressing different Xa genes, the occurrence of diseases is evident. Here we report identification of several genes that are associated with improved plant immunity against Xoo in a resistant genotype BPT-5204 in comparison with susceptible genotype TN-1. The RNA sequencing information was developed to identify the genes that could provide durable resistance in rice. Xoo-resistant rice genotype BPT-5204 with Xa 5, 13 and 21 genes is compared with sensitive Taichung Native 1 (TN-1) to identify the genetic pathways and gene networks involved in resistance mechanisms. The higher levels of salicylic acid resulted in upregulation of many pathogenesis-related (PR) and redox protein encoding transcripts which resulted in higher hypersensitive response in BPT-5204. Many Serine/threonine protein kinase, leucine-rich repeat (LRR) transmembrane protein kinase, protein kinase family genes, Wall-associated kinase (WAK) were upregulated that resulted in activation of bZIP, WRKY, MYB, DOF and HSFs transcription factors that are associated with improved plant immunity. Trichostatin A The study provided roles of many genes and their associated plant immunity pathways that can be used for developing resistant rice cultivars.Hydrocortisone is used in preterm infants. However, early disruption of growth velocities was observed in infants exposed to hydrocortisone. This retrospective study aimed to explore the postnatal brain growth of extremely preterm infants requiring hydrocortisone treatment as well as its association with perinatal factors. Extremely preterm infants exposed to hydrocortisone from 2011 to 2016 who survived up to 12 months were included. Each of them was matched with two infants not treated with hydrocortisone exhibiting similar gestational ages and nearly similar birth head circumferences. The outcome variables were brain tissue areas on MRIs performed at term-equivalent age and postnatal head circumference growth up to a corrected age of 12 months. Univariate and multiple regression analyses were performed. Infants treated with hydrocortisone (n=20) were matched with 40 infants not exposed to hydrocortisone. The infants exposed to hydrocortisone exhibited a lower birth weight (p=0.04) and a longer duration of e conditions did not show independent effect on brain growth up to the corrected age of 12 months. However, a different effect of hydrocortisone according to sex can't be excluded and needs further explorations. • Perinatal factors as birth weight and duration of mechanical ventilation were determinant for the subsequent brain growth.Sociodemographic factors and lifestyle behaviours were evidenced as correlates of self-reported 24-hour movement behaviours in high-income settings. However, it is unclear how these relations occur in a middle-income country setting, with unique cultural and social characteristics. This study aimed to examine the association between sociodemographic, dietary, and substance use factors with accelerometer-measured 24-hour movement behaviours in Brazilian adolescents. Information on sex, age, socioeconomic status (SES), family structure, dietary behaviours, and history of substance use were collected by a questionnaire. Sleep duration, sedentary behaviour, and light- and moderate-to-vigorous physical activity (LPA and MVPA) were measured using wrist-worn accelerometers. On average, females slept more (β = 21.09, 95%CI 13.18; 28.98), engaged in more LPA (β = 17.60, 95%CI 8.50; 27.13), and engaged in less sedentary behaviour (β = -16.82, 95%CI -30.01; -4.30) and MVPA (β = -4.76, 95%CI -7.48; -1.96) than males. Agers. What is New • Sex, age, and dietary behaviours were associated with the 24-hour movement behaviours. • No associations were found between socioeconomic status and substance use with the 24-hour movement behaviours.We found mycoheterotrophic seedling growth (initial mycoheterotrophy) of Gentiana zollingeri, a spring-flowering photosynthetic species of Gentianaceae family. Small seeds (about 300 µm in length) were buried in a habitat by using seed packets, and development of the subterranean seedlings to form shoots, more than 3 cm in length, was observed in symbiosis with arbuscular mycorrhizal (AM) fungi in the dark (i.e., underground of a field). Hyphal coils and their degenerations were observed in the root cortical cells of the subterranean seedlings as well as those of adult plants. Among the mycobionts identified on the basis of partial small subunit rDNA sequences, it was found that AM fungi of a lineage in Glomeraceae dominantly colonized, and the AM fungi were also dominant in adult individuals of G. zollingeri in three habitats separated one another by 17.2, 34.7, and 49.6 km. Though initial mycoheterotrophy in symbioses with AM fungi has been observed in some pteridophytes, this is the first study to demonstrate this type of symbiosis in a photosynthetic seed plant. The mycoheterotrophy means that an energy distribution occurs through the hyphal bridges of AM fungi among different photosynthetic seed plants, which may be important in constructing plant species diversity in some ecosystems.
In this manuscript, we present recent findings concerning concordance and discrepancy between biological measures and self-reports of these three outcomes of HIV programs HIV status, adherence to antiretroviral medications (ARVs) and use of and adherence to pre-exposure prophylaxis medication (PrEP), and condom use/unprotected sex.
Recent studies suggest that three successive rapid HIV tests (for those whose first test in positive) might be reasonably inexpensive and valid biological data to collect to combine with self-reports of HIV status, dried blood spots sufficiently affordable to combine with self-reports of adherence to ARVs and use of or adherence to PrEP, and that the discrepancy between self-reports of condom use and biomarkers of unprotected sex may be relatively small in high-income countries. Additional work on assessment of incorrect condom usage and breakage, standardized self-report measures of condom use, and more private data collection methodologies in low-income settings might reduce the recent observed discrepancies even further.
