The Impact

Abstract The influence of aquaporin (AQP) activity on plant water movement remains unclear, especially in plants subject to unfavorable conditions. We applied a multitiered approach at a range of plant scales to (i) characterize the resistances controlling water transport under drought, flooding and flooding plus salinity conditions; (ii) quantify the respective effects of AQP activity and xylem structure on root (Kroot), stem (Kstem) and leaf (Kleaf) conductances, and (iii) evaluate the impact of AQP-regulated transport capacity on gas exchange. We found that drought, flooding and flooding-salinity reduced Kroot and root AQP activity in Pinus taeda, whereas Kroot of the flood-tolerant Taxodium distichum did not decline under flooding. The extent of the AQP-control of transport efficiency varied among organs and species, ranging from 35%-55% in Kroot to 10%-30% in Kstem and Kleaf. In response to treatments, AQP-mediated inhibition of Kroot rather than changes in xylem acclimation controlled the fluctuations in Kroot. The reduction in stomatal conductance and its sensitivity to vapor pressure deficit were direct responses to decreased whole-plant conductance triggered by lower Kroot and larger resistance belowground. Our results provide new mechanistic and functional insights on plant hydraulics that are essential to quantifying the influences of future stress on ecosystem function.

World Environment

In today’s world, environment is exposed to lead due to various anthropogenic activities. It adversely affects plants as well as microorganisms by disturbing soil health and fertility. Bioremediation is a technique used to sequester heavy metals from the contaminated soil and it can be used to decontaminate the polluted soil. Lead-tolerant plant health promoting rhizobacteria (PHPR) can be used to enhance the efficacy of lead remediation. Lead uptake can be enhanced through bacteria by modifying root structure, secreting metal sequestering molecules in rhizosphere and alleviating lead induced phytotoxicity. For this purpose, lead-resistant auxin-producing bacteria were isolated from the rhizosphere of some plants. These auxin-producing lead-tolerant bacteria were used to treat Zea mays both in the presence and absence of lead-stress under laboratory conditions and its impact on plant growth and biochemical parameters of Zea mays were analysed.

<p class="042abstractstekst">Root structure modification can improve important agronomic traits including yield, drought tolerance and nutrient deficiency resistance. The aim of the present study was to investigate the diversity of root traits and to find simple sequence repeat (SSR) markers linked to root traits in chickpea (<em>Cicer arietinum </em>L.). This research was performed using 39 diverse accessions of chickpea. The results showed that there is significant variation in root traits among chickpea genotypes. A total of 26 alleles were detected 26 polymorphic bands were produced by 10 SSR markers in the eight linkage groups (LG). The results indicated that there is substantial variability present in chickpea<strong> </strong>germplasm for root traits.<strong> </strong>By analyzing the population structure, four subpopulations were identified.<strong> </strong>PsAS2, AF016458, 16549 and 19075 SSR markers on LG1, LG3, LG2 and LG1 linkage group respectively were<strong> </strong>associated with root traits<strong>.</strong> The research findings provide valuable information for improving root traits for chickpea breeders.</p>

Phytochemical Studies

The roots of Iostephane heterophylla are popular in Mexican traditional medicine and as such are a good candidate to develop herbal drug preparations to be used as phytomedicine. International criteria for validation and standardization of a herbal product as phytomedicine include, among others, the integration of microscopic and histochemical characteristics of the raw material, as in this case the herbal drug, to guarantee its authenticity. As an original contribution to the knowledge of the root structure of this species, fresh roots fixed in FAA, were processed with conventional histological techniques (paraffin embedment and subsequent transversal and longitudinal sections that were stained with safranin-fast green) and stained with histochemical markers for identification of cellular contents. The root description includes dermic, fundamental and vascular tissues as well as cellular contents (proteins, polysaccharides, polyphenols, condensed and hydrolyzed tannins, starches and lipids, some of which have been isolated in previous phytochemical studies). These characteristics are compared to those of other species of Asteraceae as an initial comparative study to contribute to identify medicinal plants based upon their underground parts.
