Leucaena leucocephala (Leucaena) is a leguminous tree widely cultivated in tropical and subtropical regions due to its strong environmental suitability for abiotic stresses, especially drought. However, the molecular mechanisms key pathways involved Leucaena's drought response require further elucidation. Here, we comparatively analyzed physiological early transcriptional responses of leaves roots under stress simulated by polyethylene glycol (PEG) treatments. Drought induced changes...

ABA is an important messenger that acts as a signaling mediator for regulating the adaptive response of plants to drought stress. Two production pathways, de novo biosynthesis and hydrolysis glucose-conjugated by β-glucosidase (BG), increase cellular levels in plants. catabolism via hydroxylation 8'-hydroxylase (CYP707A), or conjugation uridine diphosphate glucosyltransferase (UGT), decreases levels. The transport through ATP-binding cassette (ABC)-containing transporter proteins, members...

The bacterial wilt of peanut (Arachis hypogaea L.) caused by Ralstonia solanacearum is a devastating soil-borne disease that seriously restricted the world production. However, molecular mechanism R. solanacearum-peanut interaction remains largely unknown. We found HA4-1 and PeaFJ1 isolated from plants showed different pathogenicity inoculating more than 110 cultivated peanuts. Phylogenetic tree analysis demonstrated both belonged to phylotype I sequevar 14M, which indicates high degree...

Waxy corn has a short growth cycle and high multiple cropping index. However, after being planted in early spring, late autumn winter, it is susceptible to low temperature (LT), which reduces the emergence rate yield. Therefore, important analyze response mechanism of waxy under LT stress.All phenotype indexes inbred lines N28 were significantly higher than N67 LT. With increase stress time, all physiological showed an upward trend N67. Differentially expressed genes (DEGs) 16,017 14,435...

Abscisic acid (ABA) catabolism is one of the determinants endogenous ABA levels affecting numerous aspects plant growth and abiotic-stress responses. The major catabolic pathway triggered by 8'-hydroxylation catalysed 8'-hydroxylase, cytochrome P450 CYP707A family. In this study, full-length cDNAs AhCYP707A1 AhCYP707A2 were cloned characterized from peanut. Expression analyses showed that expressed ubiquitously in peanut roots, stems, leaves with different transcript accumulation levels,...

Acyl-CoA-binding proteins (ACBPs), members of a vital housekeeping protein family, are present in various animal and plant species. They divided into four classes: small ACBPs (class I), ankyrin-repeat II), large III), kelch-ACBPs IV). Plant play pivotal role intracellular transport, protection, pool formation acyl-CoA esters, promoting development stress response. Even though legume crops important for vegetable oils, proteins, vegetables green manure, not well investigated. To...

Pentatricopeptide repeat (PPR) proteins, with tandem 30–40 amino acids, were characterized as one kind of nucleus coding protein. They have been demonstrated to play important roles in RNA editing, plant growth and development, immunity. Although the PPR gene family has some species, less is known about this peanut, especially their functions response Ralstonia solanacearum. In study, we performed a genome-wide analysis identify genes resistance R. Here, 389, 481, 1079 identified from...

Pyruvate kinase (PK), a pivotal enzyme in glycolysis, serves as multifunctional regulator of plant growth, development, and stress adaptation. Despite its significance, the functional roles PKs peanut remain largely unexplored. Here, we performed genome-wide identification systematic characterization PK genes cultivated peanut, identifying 21 AhPK (AhPK1–AhPK21). Phylogenetic classification divided these into two subfamilies: PKc (comprising PKc-1 PKc-2 subgroups) PKp PKp-α PKp-β subgroups)....

Soybean (Glycine max (L.) Merr.) is a significant economic oilseed crop, and saline-alkali soils restrict soybean yield. Identifying salt-tolerant genes key strategy for enhancing productivity under conditions. The roles of the GmABCB gene family in growth, development, stress resistance remain incompletely understood. Bioinformatics approaches were employed to identify analyze genes. A total 39 identified analyzed genome, focusing on their phylogenetic relationships, chromosomal...

Salt stress severely constrains global crop productivity. However, most sweet corn cultivars exhibit weak tolerance to salt stress. In this study, two CSSLs, salt-tolerant line D55 and salt-sensitive D96, were selected as materials. We conducted comparative phenotyping physiological profiling of seedlings under salinity treatment, transcriptome analysis was carried out by sampling root tissues at 0 h, 4 12 72 h post-treatment. The results indicated that exhibited enhanced seedling height,...

Bacterial wilt caused by Ralstonia solanacearum is a serious soil-borne disease that limits peanut production and quality, but the molecular mechanisms of response to R. remain unclear. In this study, we reported first work analyzing transcriptomic changes resistant susceptible leaves infected with HA4-1 its type III secretion system mutant strains cutting leaf method at different timepoints (0, 24, 36, 72 h post inoculation). A total 125,978 differentially expressed genes (DEGs) were...

A rate-limiting step in abscisic acid (ABA) biosynthesis plants is catalyzed by 9-cis-epoxycarotenoid dioxygenase (NCED). Here we present the cloning, characterization of a cDNA from dehydrated peanut (Arachis hygogaea L.) leaves that encodes putative NCED. The 2486-bp full-length (designated as AhNCED1), obtained rapid amplification ends (RACE), has an open reading frame 601 amino residues and protein with calculated molecular weight 66.86 kDa isoelectric point 8.39. Sequence analysis shows...

The vase life of cut flowers is largely affected by post-harvest water loss. Cuticular wax the primary barrier to uncontrolled loss for aerial plant organs. Studies on leaf cuticular transpiration have been widely conducted; however, little known about in flowers. Here, rate and composition three lily cultivars were determined. minimum conductance tepal cuticles was higher at green bud than open flower stage. Lily exhibited cultivar- organ-specific differences, where from tepals leaves...

Ultrasonic (US) treatment is an efficient method to induce crop tolerance against heavy metal toxicity; however, US-induced aluminum (Al) in peanuts was rarely studied. This study comprised of two treatments, namely, CK, without ultrasonic treatment, and US, seed for 15 min.
