The jujube (Ziziphus jujuba Mill.), a member of family Rhamnaceae, is major dry fruit and traditional herbal medicine for more than one billion people. Here we present high-quality sequence the complex genome, first genome using an integrated strategy. final assembly spans 437.65 Mb (98.6% estimated) with 321.45 anchored to 12 pseudo-chromosomes contains 32,808 genes. has undergone frequent inter-chromosome fusions segmental duplications, but no recent whole-genome duplication. Further...

Association mapping can quickly and efficiently dissect complex agronomic traits. Rapeseed is one of the most economically important polyploid oil crops, although its genome sequence not yet published. In this study, a recently developed 60K Brassica Infinium(®) SNP array was used to analyse an association panel with 472 accessions. The single-nucleotide polymorphisms (SNPs) were in silico mapped using 'pseudomolecules' representative rapeseed establish their hypothetical order perform seed...

Terminal drought during the reproductive stage is a major constraint to yield of chickpea in many regions world. Termination watering (WS) podding small-seeded desi (Cicer arietinum L.) cultivar, Rupali, and large-seeded kabuli Almaz, induced decrease predawn leaf water potential (LWP), rate photosynthesis, stomatal conductance. Compared well-watered (WW) controls, WS treatment reduced flower production by about two-thirds. In WW treatment, 15% flowers aborted 42% (Rupali) 67% (Almaz) pods...

Although Rho-associated kinase (ROCK) activity has been implicated in cardiovascular diseases, the tissue- and isoform-specific roles of ROCKs vascular response to injury are not known. To address role this process, we generated haploinsufficient Rock1 (Rock1(+/-)) Rock2 (Rock2(+/-)) mice performed carotid artery ligations. Following intervention, found reduced neointima formation Rock1(+/-) compared with that WT or Rock2(+/-) mice. This correlated decreased smooth muscle cell proliferation...

Unreduced gametes (gametes with the somatic chromosome number) may provide a pathway for evolutionary speciation via allopolyploid formation. We evaluated effect of genotype and temperature on male unreduced gamete formation in Brassica allotetraploids their interspecific hybrids. The frequency post-meiosis was estimated sporads from dyads or giant tetrads, pollen viable compared normal pollen. Giant tetrads were twice volume presumably resulted pre-meiotic doubling number. defined as more...

Drought is one of the common abiotic stresses that limit wheat production worldwide. To ensure food security for rapidly increasing world populations, improving yield under drought stress urgent and relevant. In this study, a RNA-seq analysis was conducted to study effects on transcriptome changes during reproductive stages field conditions. Our results indicated early periods had more severe impact development, gene expression compared with around flowering periods. total, 115,656 genes...

Drought stress can directly inhibit seedling establishment in canola (Brassica napus), resulting lower plant densities and reduced yields. To dissect this complex trait, 140 B. napus accessions were phenotyped under normal (0.0 MPa, S0) water-stressed conditions simulated by polyethylene glycol (PEG) 6000 (–0.5 S5) a hydroponic system. Phenotypic variation heritability indicated that the root to shoot length ratio was reliable indicator for water tolerance. Thereafter, 66 (16 tolerant, 34...

Abstract Drought stress poses a severe threat to global wheat production, necessitating an in-depth exploration of the genetic basis for drought tolerance associated traits. This study employed 90 K SNP array conduct genome-wide association analysis, unravelling determinants key traits related in wheat, namely plant height, root length, and shoot dry weight. Using mixed linear model (MLM) method on 125 accessions subjected both well-watered treatments, we identified 53 SNPs significantly...

We introduce and review Brassica crop improvement via trigenomic bridges. Six economically important species share three major genomes (A, B, C), which are arranged in diploid (AA, BB, CC) allotetraploid (AABB, AACC, BBCC) the classical triangle of U. Trigenomic bridges interspecific hybrid plants that contain various combinations, either triploid (ABC), unbalanced tetraploid (e.g., AABC), pentaploid AABCC) or hexaploid (AABBCC). Through bridges, breeders can access all genetic resources U...

Light-harvesting chlorophyll a/b-binding protein (LHCP) is one of the most abundant chloroplast proteins in plants. Its main function to collect and transfer light energy photosynthetic reaction centers. However, roles different LHCPs light-harvesting antenna systems remain obscure. Exploration nucleotide variation genes encoding LHCP can facilitate a better understanding functions LHCP. In this study, variations Lhcb1, gene barley, were investigated across 292 barley accessions collected...

Heat and drought are among the major obstacles confronting crop production under climate change. The present study was conducted to evaluate 50 diverse wheat genotypes for cell membrane stability (CMS) chlorophyll content at seedling anthesis stages heat stress conditions, understand effect of two abiotic factors find promising future breeding. Experiments were in glasshouse (seedling stage) field (anthesis stage). Analysis variance showed significant variation (P ≤ 0.05) all traits stages....
