Previous studies suggest that abscisic acid (ABA) stimulates the activities of antioxidant enzymes under normal and chilling temperature enhanced resistance in Stylosanthes guianensis. The objective this study was to test whether nitric oxide (NO) is involved ABA-induced guianensis due its nature as a second messenger stress responses. Plants were treated with NO donors, ABA, ABA combination scavengers or synthase (NOS) inhibitor their effects on activity production compared. results showed...
Abscisic acid (ABA) regulates the plant's adaptive responses to abiotic stresses. Over-expression of 9-cis-epoxycarotenoid dioxygenase gene (SgNCED1) in transgenic tobaccos increased ABA content and tolerance drought salt H2O2 nitric oxide (NO) contents were enhanced guard cells mesophyll plants, accompanied with transcripts activities antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) glutathione reductase (GR). The enhancements NO plants...
Litchi is an evergreen woody tree widely cultivated in subtropical and tropical regions. Defective flowering a major challenge for litchi production time of climate change global warming. Previous studies have shown that high temperature conditions encourage the growth rudimentary leaves panicles suppress flowering, while reactive oxygen species (ROS) generated by methyl viologen dichloride hydrate (MV) promote abortion leaves. To understand molecular function ROS-induced litchi, we...
The banana (Musa spp.) peel undergoes rapid softening during ripening, leading to finger drop and a shortened shelf life. regulatory mechanism behind this process remains be elucidated. In study, we confirmed the role of in uncovered underlying transcriptional network. Cell wall-related (CWR) genes were substantially upregulated both zone ethylene-induced ripening. Transcriptome analysis genome-wide profiling chromatin accessibility transcription factor (TF) binding revealed that two key...
Stylosanthes guianensis (Aublet) Sw. is an important pasture legume in tropical and subtropical countries. Chilling injury of S. a serious problem cultivated areas. An experiment was conducted under controlled conditions to study the effect abscisic acid (ABA) on its relation antioxidant systems chilling stress. seedlings were sprayed with 10 mg L −1 ABA or water. One day later, plants transferred 10°C growth chamber grown for 7 d 12‐h photoperiod at 160 μmol m −2 s photosynthetic photon...
Star fruit (Averrhoa carambola) is an important tree in tropical and subtropical Asia. The blooms several times fruits accordingly within one year. Controlling the flowering time understanding physiological mechanism of induction floral buds A. carambola are indispensable to industry. In this study, potted trees were subjected drought stress a growth chamber. To avoid excessive leaf abscission, watered every 7 d sprayed with water 2 d. rate was recorded, carbohydrate contents leaves, phloem,...
The objective of this work was to test whether Ca2+, a second messenger in stress response, is involved ABA-induced antioxidant enzyme activities Stylosanthes guianensis. Plants were sprayed with abscisic acid (ABA), calcium channel blocker, LaCl3, chelator, ethylene glycol-bis(β-amino ethyl ether)-N,N,N', N'-tetraacetid (EGTA), and ABA combination LaCl3 or EGTA. Their effects on superoxide dismutase (SOD) ascorbate peroxidase (APX) chilling resistance compared. results showed that decreased...
Passion fruit (Passiflora edulis), a commercially vital tropical crop, faces flowering instability due to photoperiod-sensitive patterns, particularly under the cloudy, rainy climates of subtropical regions. To mitigate floral suppression during unfavorable light conditions, this study implemented dual-modality strategy combining 16 h daily supplementary lighting (460 nm blue + 630 red spectrum) and foliar application high-phosphorus-containing nutrient, Plant-Prod...
Vegetative growth and reproductive strongly competes with each other during panicle development in litchi (Litchi chinensis Sonn.). We herein investigated the roles of hydrogen peroxide nitric oxide competition between rudimentary leaves development. The results show that chilling-induced flowering increased H2O2 NO contents mixed buds. Treatments sodium nitroprusside (SNP), donor, methyl viologen dichloride hydrate (MV), superoxide generator, MV SNP treatments promoted abscission encouraged...
In order to investigate the role of abscisic acid in litchi flowering, trees were treated with exogenous ABA before or when panicle primordia emerged. The results showed that spraying emerged reduced number leaves per panicle, enhanced axillary panicles and ratio total nodes panicle. When emerged, flowers ABA-treated was higher than control. biosynthesis inhibitor naproxen percentage flowering terminal shoots one suppressed homologue gene (LcAP1). To confirm whether AP1 expression depended...
Litchi is one of the most important subtropical evergreen fruit trees in southern Asia. Previous studies indicated that high-temperature conditions encourage growth rudimentary leaves panicles and suppress flowering. We have demonstrated methyl viologen dichloride hydrate (MV) sodium nitroprusside (SNP) promoted flowering litchi partially by inhibiting via reactive oxygen species (ROS) nitric oxide (NO). In present study, we examined microstructure ultrastructure, programmed cell death (PCD)...
Litchi is an important woody fruit tree. Floral initiation in litchi triggered by low temperatures. However, defective flowering a major challenge for production times of climate change and global warming. Previous studies have shown that the reactive oxygen species (ROS) generated methyl viologen dichloride hydrate (MV) promotes flowering. In this study, potted trees were transferred to growth chambers low-temperature (LT), medium-temperature (MT), high-temperature (HT) treatments. Trees at...
Warm winter and hot spring attributed to global warming affected floral development may induce abortion, resulted in poor flowering litchi. To identify genes potentially involved litchi six RNA-sequencing (RNA-Seq) libraries of the developing panicles (DPs) under low temperature (LT) conditions shrinking (SPs) high (HT) were constructed. 3.07–8.97 × 106 clean reads generated. Digital expression DPs with that SPs was compared. As a result, 1320 up-regulated 981 down-regulated differentially...
Litchi is an important subtropical fruit tree that requires appropriately low temperature to trigger floral initiation. Our previous studies have shown reactive oxygen species (ROS) are involved in litchi flowering. To identify oxidative stress-induced flowering related genes leaves, ‘Nuomici’ potted trees were grown at medium low-temperature conditions (18/13 °C for day/night, medium-temperature). The treated with the ROS generator methyl viologen dichloride hydrate (MV) as MV-generated...
Litchi trees flower at the apex of terminal shoots. Flowering is affected by maturity shoots before growth cessation occurs during winter. In this study, we focused on changes flowering in three important cultivars, Guiwei, Feizixiao, and Huaizhi, from Dec. 2012 to Mar. 2013 under natural winter conditions. rate, carbohydrate accumulation, expression flowering-related genes were determined different developmental stages with dark green, yellowish green red leaves, respectively. The results...
Litchi is one of the most important subtropical evergreen fruit trees in Southern Asia. floral buds are a mix axillary or apical panicle primordia, leaf and rudimentary leaves. Under usual winter early spring conditions, primordia prevail, leaves abscise when low temperatures reach certain threshold. The ultimately develop into pure panicles. Understanding regulatory mechanism senescence great importance for litchi flowering. In this study, potted at differentiation stage were treated with...
