Abstract Plants of wheat growing in pots with silicon (Si) applied before sowing had greater plant height, leaf area, and dry materials compared to those without Si well watering conditions. Drought stress was by withholding for 12 days from 26‐day old seedlings. In the conditions, plants Si‐applied soil could maintain higher relative water content (RWC), potential area applied. Moreover, were not significantly changed drought while decreased, this mainly due growth inhibition shoots....
Abstract Na+ uptake by plant roots has largely been explored using species that accumulate little into their shoots. By way of contrast, the halophyte Suaeda maritima accumulates, without injury, concentrations order 400 mm NaCl in its leaves. Here we report cAMP and Ca2+ (blockers nonselective cation channels) Li+ (a competitive inhibitor uptake) did not have any significant effect on S. when plants were 25 or 150 (150 is near optimal for growth). However, inhibitors K+ channels, TEA+ (10...
Soil salinity is an increasingly serious problem worldwide that reduces agricultural output potential. Selected beneficial soil bacteria can promote plant growth and augment tolerance to biotic abiotic stresses. Bacillus subtilis strain GB03 has been shown confer promotion stress in the model Arabidopsis thaliana. Here we examined effect of this bacterium on salt legume forage crop, white clover. Plants clover (Trifolium repens L. cultivar Huia) were grown from seeds with or without...
Puccinellia tenuiflora is a useful monocotyledonous halophyte that might be used for improving salt tolerance of cereals. This current work has shown P. stronger selectivity K+ over Na+ allowing it to maintain significantly lower tissue and higher concentration than wheat under short- or long-term NaCl treatments. To assess the relative contribution efflux influx net accumulation, unidirectional 22Na+ fluxes in roots were carried out. It was firstly found into root (by 31-37%) 100 150 mM...
Puccinellia tenuiflora is a typical salt-excluding halophytic grass with excellent salt tolerance. Plasma membrane Na+/H+ transporter SOS1, HKT-type protein and tonoplast antiporter NHX1 are key Na+ transporters involved in plant Based on our previous research, we had proposed function model for these homeostasis according to the expression of PtSOS1 Na+, K+ levels P. responding stress. Here, analyzed patterns PtSOS1, PtHKT1;5 PtNHX1 under 25 150 mM NaCl further validate this by combining...
Summary Salinity and drought are major environmental factors limiting the growth productivity of alfalfa worldwide as this economically important legume forage is sensitive to these kinds abiotic stress. In study, transgenic lines expressing both tonoplast NXH H + ‐ PP ase genes, Zx NHX VP 1‐1 from xerophyte Zygophyllum xanthoxylum L., were produced via Agrobacterium tumefaciens ‐mediated transformation. Compared with wild‐type ( WT ) plants, plants co‐expressing grew better greater plant...
Atriplex canescens (fourwing saltbush) is a C4 perennial fodder shrub with excellent resistance to salinity. However, the mechanisms underlying salt tolerance in are poorly understood. In this study, 5-week-old A. seedlings were treated various concentrations of external NaCl (0-400 mM). The results showed that growth was significantly stimulated by moderate salinity (100 mM NaCl) and unaffected high (200 or 400 NaCl). Furthermore, higher photosynthetic capacity under treatments (except for...
Plant h igh-affinity K + t ransport (HKT) proteins are so named because of their relation to bacterial and fungal transporters that mediate high-affinity uptake. The view HKT family members sodium-selective uniporters or sodium-potassium symporters is widely held. We have found one the rice also functions as a Ca 2+ -permeable cation channel conducts current carried by wide range monovalent divalent cations. gene, OsHKT2;4 , expressed in several cell types, including root hairs vascular...
Background and Aims In order to cope with arid environments, the xerohalophyte Zygophyllum xanthoxylum efficiently compartmentalizes Na+ into vacuoles, mediated by ZxNHX, maintains stability of K+ in its leaves. However, function ZxNHX controlling homeostasis at whole-plant level remains unclear. this study, role regulating expression genes involved transport spatial distribution was investigated. Methods The maintaining Z. studied using post-transcriptional gene silencing via...
The inward-rectifying K+ channel AKT1 constitutes an important pathway for acquisition in plant roots. In glycophytes, excessive accumulation of Na+ is accompanied by deficiency under salt stress. However, the succulent xerophyte Zygophyllum xanthoxylum, which exhibits excellent adaptability to adverse environments, concentration remains at a relatively constant level despite increased levels salinity and drought conditions. this study, contribution ZxAKT1 maintaining homeostasis Z....
Nitrate (NO3-) and ammonium (NH4+) are major inorganic nitrogen (N) supplies for plants, but NH4+ as the sole or dominant N source causes growth inhibition in many known toxicity. Small amounts of NO3- can significantly mitigate toxicity, anion channel SLAC1 homolog 3 (SLAH3) is involved this process, mechanistic detail how SLAH3 regulates nitrate-dependent alleviation toxicity still largely unknown. In study, we identified SnRK1.1, a central regulator energy homeostasis, various stress...
Abstract Revealing the genetic basis for stress-resistant traits in extremophile plants will yield important information crop improvement. Zygophyllum xanthoxylum, an extant species of ancient Mediterranean, is a succulent xerophyte that can maintain favorable water status under desert habitats; however, this adaptive trait poorly understood. Furthermore, phylogenetic position Zygophyllales, to which Z. xanthoxylum belongs, remains controversial. In study, we sequenced and assembled...
Lotus corniculatus L. is an important legume for forage, but sensitive to salinity and drought. To develop salt- drought-resistant corniculatus, ZxNHX ZxVP1-1 genes encoding tonoplast Na+/H+ antiporter H+-pyrophosphatase (H+-PPase) from a succulent xerophyte Zygophyllum xanthoxylum L., which well adapted arid environments through accumulating Na+ in its leaves, were transferred into this forage. We obtained the transgenic lines co-expressing (VX) as expressing gene alone (VP). Compared with...
Codonopsis pilosula (Franch.) Nannf. is a traditional Chinese herbal medicinal plant and low-cost succedaneum for Panax ginseng contains various bioactivity components. In this work, we first evaluated the effects of inoculation growth-promoting rhizobacteria Bacillus amyloliquefaciens strain GB03 on growth metabolite accumulation C. pilosula. The results demonstrated that application B. significantly improved compared to DH5α, Luria broth medium, water treatment, respectively. On other...
SMALL AUXIN-UP RNAs (SAURs) comprise the largest family of early auxin response genes. Some SAURs have been reported to play important roles in plant growth and development, but their functional relationships with signaling remain unestablished. Here, we report Arabidopsis (Arabidopsis thaliana) SAUR15 acts downstream factors ARF6,8 ARF7,19 regulate signaling-mediated lateral root (LR) adventitious (AR) formation. The loss-of-function mutant saur15-1 exhibits fewer LRs ARs. By contrast,...
