Significance This work reports discovery of a unique gene important for rice agriculture. A significant yield enhancement in modern cultivar was achieved by identification gene, SPIKELET NUMBER ( SPIKE ) Indonesian landrace. The increased grain an indica IR64, which is widely grown the tropics, over four seasons at field level and improved plant architecture without changing quality or growth period, are regional adaptability. These results indicate finding will be extremely valuable...
A decline in rice (Oryza sativa L.) production caused by heat stress is one of the biggest concerns resulting from future climate change. Rice spikelets are most susceptible to at flowering. The early-morning flowering (EMF) trait mitigates heat-induced spikelet sterility stage escaping during daytime. We attempted develop near-isogenic lines (NILs) for EMF indica-type genetic background exploiting locus wild rice, O. officinalis (CC genome). stable quantitative (QTL) flower opening time...
Alzheimer's disease (AD) is an irreversible neurodegenerative disorder with a complex pathophysiology. Type 2 diabetes (T2D) strong risk factor for AD that shares similar abnormal features including metabolic dysregulation and brain pathology such as amyloid and/or Tau deposits. Emerging evidence suggests circulating branched-chain amino acids (BCAAs) are associated T2D. While excess BCAAs shown to be harmful neurons, its connection poorly understood. Here we show individuals have elevated...
ABSTRACT Studies on heat tolerance in rice ( Oryza sativa L.) have focused a range of accessions that are currently not grown or cultivated small localized geographic regions, while popular cultivars occupying millions hectares been tested for their response to stress. Hence, 18 across tropical and subtropical regions were subjected 38°C 6 h stress at anthesis five selected contrasting entries exposed six consecutive days (6 each day) coinciding with both gametogenesis anthesis. Among the...
Abstract Background High-protein diets are often enriched with branched-chain amino acids (BCAAs) known to enhance protein synthesis and provide numerous physiological benefits, but recent studies reveal their association obesity diabetes. In support of this, or BCAA supplementation is shown disrupt glucose metabolism while restriction improves it. However, it not clear if these primary, direct effects BCAAs secondary other changes during chronic manipulation dietary BCAAs. Methods...
Total spikelet number per panicle (TSN) is one of the determinants grain productivity in rice (Oryza sativa L.). In this study, we attempted to detect quantitative trait loci (QTLs) for TSN introgression lines with high TSN, derived from cross Indica Group variety IR 64 new plant type lines. Two QTLs were detected on long arm chromosome 12: qTSN12.1 BC4F2 population YTH63/IR and qTSN12.2 BC4F3 YTH83/IR 64. main tiller was significantly higher near-isogenic (NILs) (IR 64-NIL1; 188.6)...
Type 2 diabetes (T2D) is a challenging health concern worldwide. A lifestyle intervention to treat T2D difficult adhere, and the effectiveness of approved medications such as metformin, thiazolidinediones (TZDs), sulfonylureas are suboptimal. On other hand, bariatric procedures Roux-en-Y gastric bypass (RYGB) being recognized for their remarkable ability achieve remission, although underlying mechanism not clear. Recent evidence points branched-chain amino acids (BCAAs) potential contributor...
Abstract Cotton is a tropical/subtropical crop and innately susceptible to cold. Using an approach that integrates morphological, biochemical, transcriptome analyses, the study aimed understand molecular underpinnings of phenotypic adjustments in cotton seedlings under cold stress. Exposure six accessions 15°C during seedling stage significantly reduced chlorophyll content, stomatal conductance, plant height, biomass, but increased malondialdehyde proline production. Comparative profiling...
Circulating branched-chain amino acids (BCAAs) are elevated in obesity and diabetes, recent studies support a causal role for BCAAs insulin resistance defective glycemic control. The physiological mechanisms underlying BCAA regulation poorly understood. Here we show that signaling the mediobasal hypothalamus (MBH) of rats is mandatory lowering plasma BCAAs, most probably by inducing hepatic catabolism. Insulin receptor deletion only agouti-related protein (AgRP)–expressing neurons (AgRP...
Abstract Upland cotton ( Gossypium hirsutum ) is inherently susceptible to low temperature stress especially during the early seedling growth and boll maturation stages. The goal of study identify novel sources genetic variation that can be used improve cold tolerance seed germination. Genetic diversity analysis thirty accessions from core Diversity Reference Set (GDRS) twenty recombinant inbred lines derived intercrossing mutants with altered fatty acid content profiles established in test...
Solanum lycopersicoides is a wild nightshade relative of tomato with known resistance to wide range pests and pathogens, as well tolerance cold, drought salt stress. To effectively utilize S . genetic resource in breeding for improvement, the underlying basis observable traits species needs be understood. Molecular markers are important tools that can unlock underpinnings phenotypic variation crop relatives. Unfortunately, DNA specific limited number, distribution polymorphism rate. In this...
Abstract Key message Alien introgressions that were captured in the genome of diploid plants segregating from progenies monosomic alien addition lines S. lycopersicoides confer novel phenotypes with commercial and agronomic value tomato breeding. Solanum is a wild relative natural adaptation to wide array biotic abiotic challenges. In this study, we identified characterized (MAALs) establish their potential as donors breeding for target trait improvement tomato. Molecular genotyping 28 38...
