Rice, a globally important food crop, faces significant challenges due to salt and drought stress. These abiotic stresses severely impact rice growth and yield, manifesting as reduced plant height, decreased tillering, reduced biomass, and poor leaf development. Recent advances in molecular biology and genomics have uncovered key physiological and molecular mechanisms that rice employs to cope with these stresses, including osmotic regulation, ion balance, antioxidant responses, signal transduction, and gene expression regulation.

Preharvest sprouting (PHS) is an undesirable trait that decreases yield and quality in rice production. Understanding the genes and regulatory mechanisms underlying PHS is of great significance for breeding PHS-resistant rice. In this study, we identified a mutant, preharvest sprouting 39 (phs39), that exhibited an obvious PHS phenotype in the field.

Article Synopsis
  • Deep eutectic solvent (DES) is a new eco-friendly solvent used to effectively pretreat lignocellulosic materials like soybean straw.
  • By adding p-toluenesulfonic acid as a catalyst to create a ternary DES with benzyltriethylammonium chloride and glycerol, significant removal of lignin (92.0%) and hemicellulose (88.2%) was achieved under optimal conditions.
  • The pretreated soy straw showed great potential for enzymatic hydrolysis, yielding high concentrations of glucose (37.3 g/L) and reducing sugars (42.3 g/L) after using cellulase, making this method a promising approach for turning agricultural waste into useful sugars.

Two causal OsTTL and OsSAPK1 genes of the key locus qNL3.1 significantly associated with seed germination under salt stress were identified via a genome-wide association study, which could improve rice seed germination under salt stress. Rice is a salt-sensitive crop, and its seed germination determines subsequent seedling establishment and yields.

Article Synopsis
  • The study identified a new gene, OsHIPL1, linked to rice seed vigour, which is crucial for successful direct seeding.
  • OsHIPL1 affects seed germination by regulating levels of abscisic acid (ABA), with alterations in ABA-related gene expression observed in mutant strains compared to standard rice plants.
  • Additionally, OsHIPL1 interacts with a water transport protein (OsPIP1;1), suggesting it plays a role in enhancing water uptake to improve germination rates, with a specific haplotype showing a positive correlation with seed germination.

Article Synopsis
  • Seed germination is crucial for plants, but the mechanisms behind it aren't fully understood; this study identified 19 quantitative trait loci (QTLs) related to rice seed germination through genome-wide studies.
  • Two major stable QTLs, qSG4 and qSG11.1, were consistently linked to germination rates and indexes over two years, highlighting their importance.
  • The gene OsPK5, which encodes a pyruvate kinase, is identified as a key regulator of seed germination; disruptions in OsPK5 lead to slower germination and issues with energy metabolism, offering new insights for rice breeding improvements.

Retinitis pigmentosa (RP) is a major cause of blindness that is difficult to diagnose and treat. PKM2, a subtype of pyruvate kinase, is strongly associated with oxidative stress and is expressed in photoreceptors. We investigated whether PKM2 reduces photoreceptor cell apoptosis and evaluated possible antiapoptotic mechanisms in RP.

Objective: Middle-age patients with retinal detachment (RD) exhibit a loss of visual information, and previous studies of functional magnetic resonance imaging (fMRI) have demonstrated abnormal spontaneous activity in the RD brain. Therefore, this study assessed changes in local functional connectivity density (lFCD) and long-range functional connectivity density (longFCD) in middle-age RD patients during resting-state FC.

Methods: In total, 32 middle-age patients with RD (18 men and 14 women), and 32 age-, sex-, and education-matched normal controls (NCs) (18 men and 14 women) were recruited and underwent functional magnetic resonance examination in the resting state.

Background: The outcomes of patients with postmenopausal breast cancer(PBC) can be improved through the early detection of intraocular metastases(IOMs). In this study, we investigated patients with PBC, and compared those with IOMs with those with non-intraocular metastases(NIOMs) in terms of blood lipid levels, and then differentiated the risk factors associated with IOMs.

Methods: Student's t-test and a chi-square test were used to discriminate between the IOMs and NIOMs groups.
