DROUGHT AND SALT TOLERANCE IN PLANTS CRITICAL REVIEWS IN PLANT SCIENCES

Cytokinin (CK) is an important phytohormone, which not only plays significant role in plant development but also involves in mediating plant stress tolerance. Previous studies showed that the drought tolerance can be improved by stress-inducible overexpression of adenine isopentenyl transferase (IPT[r]

18. The amount of nitrogen and phosphorous cycling through an ecosystem is greatly affected by local environmental conditions, such as heavy rainfall or the removal of large numbers of plants. The amount of carbon in an ecosystem is seldom signifi- cantly affected by such factors bec[r]

A number of excellent papers and reviews are available in several areas of plant proteomics, dealing with the establishment of reference protein maps in plant tissues and organelles (Bar[r]

The ultimate goal of this work was to detect the role of transcription factors (TFs) concordantly expressed with genes related to programmed cell death (PCD) during PCD and salt stress.

The present investigation was carried out in 73 eggplant genotypes to assess the nature and extent of genetic variability, heritability and genetic advance under normal (0% PEG-6000 as control) and osmotic stress condition (12 % PEG-6000) in germination phases in three replications in a completely r[r]

Although miRNAs are reportedly involved in the salt stress tolerance of plants, miRNA profiling in plants has largely remained restricted to glycophytes, including certain crop species that do not exhibit any tolerance to salinity. Hence, this manuscript describes the results from the miRNA profilin[r]

grown on alluvial soils that had previously been contaminated at different concentrations of Cu. The main purposes of the research were to determine the effects of Cu and phosphorus applications on plant growth and Cu uptake by Brassica juncea L. Mature plants were ha[r]

Drought is the major environmental stress threatening crop-plant productivity worldwide. Identification of new genes and metabolic pathways involved in plant adaptation to progressive drought stress at the reproductive stage is of great interest for agricultural research.

Hence research efforts were made to develop high yielding, early maturing varieties with tolerance to drought, salinity and diseases including less loss in delayed harvesting.

Lentil (Lens culinaris Medikus) is an important winter season grain legume crop, mostly grown on residual soil moisture and is frequently subjected to terminal drought and heat stress, that results in low and variable seed yields. Moreover, delay in sowing even for two weeks causes the reproductive[r]

Physiological parameters and expression levels of drought related genes were analyzed in early vegetative stage of two bread wheat cultivars (Sids and Gmiza) differ in drought tolerance capacity. Both cultivars were imposed to gradual water depletion started on day 17 till day 32 after sowing. Sids,[r]

The most compounds have varied effects on the development of mycelia growth of fungi and the effect on sporulation rate and inhibition of germination ranging from a fungistatic effect to complete inhibition. The answer depends on the arrest of compounds derived from extracts of the[r]

Fresh leaves of A. marina were cut into 0.1 × 0.3 cm pieces and fi xed for 24 h with 2.5% glutaraldehyde at room temp- erature. The materials were then washed with 0.1 M phos- phate buffer solution ( pH 7.0), fi xed for 1.5 h with 1% OsO 4 and washed again with dist[r]

MicroRNAs (miRNAs) play critical roles in the processes of plant growth and development, but little is known of their functions during dehydration stress in wheat. Moreover, the mechanisms by which miRNAs confer different levels of dehydration stress tolerance in different wheat genotypes are unclea[r]

Abstract: The impact of salinity on three arboreal mangrove plants, Sonneratia apetala ( Sa ), S. caseolaris ( Sc ) and Rhizophora stylosa ( Rs ),[r]

Plant growth promoting rhizobacteria are found in the rhizosphere of plants worldwide and enhance their growth and development under unfavorable environmental condition. In the present investigation, twelve plant growth promoting rhizobacteria were isolated from the rhizosphere of different plants.[r]

Root characteristics play an important role in the drought mitigation strategies of maize plants the root length and the root volume results show that a significant increase in root volu[r]

Drought is the major abiotic stress that results in severe loss of yield to crops. It is estimated that there will be a steep rise in global water consumption in the coming years. On the other hand, it is also estimated that the sources of water will deplete due to rise in temperature and climate ch[r]

Salt tolerance in grapevine is associated with chloride (Cl− ) exclusion from shoots; the rate-limiting step being the passage of Cl− between the root symplast and xylem apoplast.

DNA methylation plays a vital roles in plant response to drought stress. Therefore, the present study was carried out to investigate differential cytosines methylation in leaves of maize under drought stress by using AMP method. Thirty days old maize seedlings were subjected to water deficit for nin[r]
