Summary

Plants exhibits different types of abiotic and biotic stresses continuously throughout its life cycle. Being sessile, plants can’t avoid the stresses through escaping their natural habitat but can tolerate to a certain extent through modifying its physiology and metabolism. In addition, plants are also capable in formation of new molecules and molecular mechanisms to withstand in stressed condition. Different types of physiological and molecular mechanisms i.e.; ion homeostasis and compartmentalization, synthesis of compatible solutes, activation of antioxidants, hormonal regulation is developed in plant to combat with stressed condition of plants. Increment of crop production is crucial to feed the increasing population throughout the world. Both abiotic and biotic stress hinder the crop production to a great extent.

 

Nowadays, many researches are undertaken to escape the stresses or to induce tolerance in plants. Scientists are trying to improve the tolerance mechanisms by exogenous application of substances. To meet up the demand of upcoming food crisis, more high yielding crop varieties should be introduced, incorporating the knowledge of stress tolerance mechanism.

 

In this special issue, we aimed at accumulating the recent progress in plant biology research. Articles on recent advances in plant biology (original research papers, short communications, reviews, mini-reviews) are welcome.

    Abstract Allium senescens, is an important economic and ecological grassland plant with drought-resistant characteristics. A TCP protein transcription factor is important in the regulation of plant development and adverse responses. However, the mechanism by which TCP transcription functions in drought resistance in Allium senescens is still not clear. Here, we obtained a total of 190,305 transcripts with 115,562 single gene clusters based on RNA-Seq sequencing of Allium senescens under drought stress. The total number of bases was 97,195,096 bp, and the average length was 841.06 bp. Furthermore, we found that there were eight genes of the TCP family that… More >

    DURGA KORA, ANANYA DEY, BABITA PAL, UTHPAL KRISHNA ROY, NIVEDITA DEY, TREESHA BHATACHARJEE, SOUMEN BHATTACHARJEE
    BIOCELL, Vol.47, No.3, pp. 503-521, 2023, DOI:10.32604/biocell.2023.025744
    (This article belongs to the Special Issue: Physiology and Molecular Biology of Plant Stress Tolerance)
    Abstract The elaborate redox network of the cell, comprising of events like turnover of reactive oxygen species (ROS), redox sensing, signaling, expression of redox-sensitive genes, etc., often orchestrates with other bonafide hormonal signaling pathways through their synergistic or antagonistic action in the plant cell. The redox cue generated in plant cells under fluctuating environmental conditions can significantly influence other hormonal biosynthetic or signaling mechanisms, thereby modulating physiology towards stress acclimation and defense. There is also strong evidence of the recruitment of ROS as a ‘second messenger’ in different hormonal signaling pathways under stress. Moreover, the retrograde… More >

    Abstract Salinity is one of the major abiotic factors that limit the growth and productivity of plants. Foliar application of plant growth regulators (PGRs) may help plants ameliorate the negative impacts of salinity. Thus, a field experiment was conducted at the Botanical Garden University of Balochistan, Quetta, to explore the potential role of PGRs, i.e., moringa leaf extract (MLE; 10%), proline (PRO; 1 µM), salicylic acid (SA; 250 µM), and thiourea (TU; 10 mM) in ameliorating the impacts of salinity (120 mM) on Plantago ovata, an important medicinal plant.

    Abstract Calmodulin (CaM) proteins play a key role in signal transduction under various stresses. In the present study, the effects of a sugarcane ScCaM gene (NCBI accession number: GQ246454) on drought and salt stress tolerance in transgenic Arabidopsis thaliana and Escherichia coli cells were evaluated. The results demonstrated a significant negative role of ScCaM in the drought and salt stress tolerance of transgenic lines of A. thaliana, as indicated by the phenotypes. In addition, the expression of AtP5CS and AtRD29A, two genes tightly related to stress resistance, was significantly lower in the overexpression lines than in the wild type. The growth More >

    Abstract

    Cadmium (Cd) causes oxidative stress, which leads to the oxidation of various biomolecules by the production of reactive oxygen species (ROS) to facilitate programmed cell death (PCD). The antioxidant defense system fails to detoxify ROS when it is produced in excess. Nitric oxide (NO), a gaseous free radical and a phytohormone, regulates various physiological processes of plants. Therefore, this work was undertaken to study the effects of the application of exogenous sodium nitroprusside (SNP, a NO donor) on growth parameters, oxidative stress, accumulation of secondary metabolites, and activities of antioxidant enzymes under Cd stress.

    Abstract The metabolic activity of the fruits continues even after harvest, which results in the loss of bioactive compounds, a decrease in the quality of the fruits, softening and browning, among other negative effects. The use of certain elements such as silicon can improve postharvest quality, since it is involved in the metabolic, physiological and structural activity of plants, moreover can increase the quality of the fruits. In addition, nanotechnology has had a positive impact on crop yield, nutritional value, fruit quality and can improve antioxidant activity.

    (This article belongs to the Special Issue: Physiology and Molecular Biology of Plant Stress Tolerance)
    Abstract Dehydrins (DHNs), as members of the late embryogenesis abundant protein family, play critical roles in the protection of seeds from dehydration and plant adaptation to multiple abiotic stresses. Vitrification is a basic method in plant cryopreservation and is characterized by forming a glassy state to prevent lethal ice crystals produced during cryogenic storage. In this study, ApSK3 type DHN was genetically transformed into embryogenic calluses (EC) of Agapanthus praecox by overexpression (OE) and RNA interference (RNAi) techniques to evaluate the in vivo protective effect of DHNs during cryopreservation. The cell viability showed a completely opposite trend in OE… More >

    Abstract NAC (NAM, ATAF, CUC) is a class of transcription factors involved in plant growth regulation, abiotic stress responses, morphogenesis and metabolism. Salvia miltiorrhiza is an important Chinese medicinal herb, but the characterization of NAC genes in this species is limited. In this study, based on the Salvia miltiorrhiza genomic databases, 82 NAC transcription factors were identified, which were divided into 14 groups. Meanwhile, phylogenetic analysis, gene structure, chromosomal localization and potential role of SmNACs in abiotic stress conditions were also studied. The results revealed that some SmNACs had different structures than others, which advised that these genes may have multiple/distinct More >

    Abstract Plant U-box (PUB) E3 ubiquitin ligases play important roles in hormone signaling pathways and in response to different abiotic stresses, but little is known about U-box genes in Danshen (root of Salvia miltiorrhiza Bunge). Here, we identified and characterized 70 SmPUB genes based on its genome sequence. Phylogenetic analysis of U-box genes from S. miltiorrhiza and Arabidopsis suggested that they can be clustered into seven subgroups (I–VII). Typical U-box domains were found in all identified SmPUB genes through the analysis of conserved motifs. Moreover, qRT-PCR was applied to analyze the relative expression levels of U-box genes in S. miltiorrhiza roots and More >

    Abstract

    Drought stress is one of the major environmental obstacles that limit the production and development of apples (Malus domestica Borkh.). The role of melatonin is well known in the protection of plants under environmental stresses. In this study, we investigated the effect of melatonin on apple rootstock M. hupehensis Rehd under drought stress. The results showed that drought inhibited the growth of M. hupehensis and dramatically reduced root surface area, root volume, the number of tips and forks, and root diameter. Drought-induced growth inhibition was significantly decreased by adding melatonin. Net photosynthetic rate (Pn), intercellular CO2 concentration (Ci), stomatal
