The present study investigated and screened the top 50 most closely interacting proteins in the flowering plant Dendranthema grandiflorum ‘Jinba’ (i.e., chrysanthemum), and mapped the protein interaction network. This was to gain a comprehensive understanding of the differentially expressed proteins affected by heat stress, and clearly demonstrate the protein-protein interactions. The circles represent differentially expressed proteins, and the colors represent the differential expression of the proteins (blue for down-regulated proteins, red for up-regulated proteins). The larger the circle, the more proteins it interacted with, and the more important the protein was in the network.

Abstract
This review highlights the key role that mycorrhizal fungi play in making phosphorus (Pi) more available to plants, including pathways of phosphorus absorption, phosphate transporters and plant-mycorrhizal fungus symbiosis, especially in conditions where the level of inorganic phosphorus (Pi) in the soil is low. Mycorrhizal fungi colonization involves a series of signaling where the plant root exudates strigolactones, while the mycorrhizal fungi release a mixture of chito-oligosaccharides and liposaccharides, that activate the symbiosis process through gene signaling pathways, and contact between the hyphae and the root. Once the symbiosis is established, the extraradical mycelium acts as an extension of the… More >

Abstract Soybean (Glycine max (L.) Merr) is an agro-economic crop growing across the world to cater nutrition for both
human and animal feed due to the high oil and protein content in its edible seeds. The genes and QTLs associated
with important agronomic traits in this crop have already been identified and validated for soybean cyst nematode
(SCN), Phytophthora root and stem rot, Pythium root rot and aphid resistance, seed quality, nutrient values, and
also employed for genetic improvement in soybean. In the last decade, micro RNAs (miRNAs) have been considered the effector molecules, so the detection and characterization of novel… More >

Abstract Abiotic stresses such as drought, heat, cold, nutrient deficiency, excess salt and hazardous metals can hamper plantgrowth and development. Intensive agriculture of only a few major staple food crops that are sensitive and intolerant to environmental stresses has led to an agrarian crisis. On the other hand, nutritionally rich, gluten free and stress tolerant plants like millets are neglected and underutilized. Millets sustain about one-third of the world’s population and show exceptional tolerance to various abiotic and biotic stresses. Millets are C4 plants that are adapted to marginal and dry lands of arid and semi-arid regions, and survive low rainfall… More >

Abstract It is known that the high level of sugar including glucose suppresses seed germination through ABA signal. ABI5 is
an essential component to mediate ABA-dependent seed germination inhibition, but underlying mechanism
needs more investigation. Previous study demonstrated the PIF4 activated the expression of ABI5 to suppress seed
germination in darkness. Here we reported that PIF4 also mediated the seed germination inhibition through ABI5
under high concentration of glucose treatment. Furthermore, we found that PIF4 interacted with PAP1, the central factor to control anthocyanin biosynthesis. Such interaction was confirmed in vitro and in planta. Biochemical
and physiological analysis revealed that PAP1… More >

Abstract The halophilic unicellular green alga Dunaliella salina is characterized as the distinct tolerance to high salt in the
field. Normally the organism is concurrently subjected with salt and alkali stress, but the feature of D. salina in
response to high alkali stress was not investigated before. In this study, we used high pH stress to simulate high
alkali stress and found D. salina also showed tolerance to high alkali stress, even grown under pH at 11.0, with
high cell density and chlorophyll biosynthesis. High-throughput transcriptome analysis revealed the dramatically
different expression of genes associated with nitrogen metabolism, lipid and β-carotene… More >

Abstract Chrysanthemum is one of the most important ornamental flowers in the world, and temperature has a significant influence on its field production. In the present study, differentially expressed proteins were investigated in the leaves of Dendranthema grandiflorum ‘Jinba’ under high temperature stress using label-free quantitative proteomics techniques. The expressed proteins were comparatively identified and analyzed. A total of 1,463 heat-related, differentially expressed proteins were successfully identified by Liquid Chromatography-tandem Mass Spectrometry (LC-MS/MS), and 1,463 heat-related, differentially expressed proteins were successfully identified by mass spectrometry after a high temperature treatment. Among these, 701 proteins were upregulated and 762 proteins were downregulated.… More >

Abstract This study was undertaken to investigate oxidative stress tolerant mechanisms in chilli (Capsicum annuum L.)
under drought genotypes through evaluating morphological, physiological, biochemical and stomatal parameters.
Twenty genotypes were evaluated for their genetic potential to drought stress tolerant at seedling stage. Thirty
days old seedlings were exposed to drought stress induced by stop watering for the following 10 days and rewatering for the following one week as recovery. Based on their survival performance, two tolerant genotypes
viz. BD-10906 and BD-109012 and two susceptible genotypes viz. BD-10902 and RT-20 were selected for studying
the oxidative stress tolerance mechanism. Drought reduced root… More >

Abstract Somatic cells respond to considerable stress, and go through a series of phytohormone pathways, then forming an embryo. The developmental process is recorded as somatic embryogenesis (SE). One of the key components regulating SE are the microRNAs (miRNAs). Despite previous studies, it is still not clear exactly how miRNAs exert their function of regulating targets during conditionally activated early SE. Here, we use Liriodendron sino-americanum as a model system and perform a combined analysis of microfluidic chips and degradome sequencing to study this process. We identified a total of 386 conserved miRNAs and 153 novel miRNAs during early SE. According… More >

Abstract Brassinosteroids participate in many physiological processes in plants; however, their regulatory roles on the activities of the enzymes involved in dark phase of photosynthesis remains elusive. In this study, detached leaves and protoplasts of maize seedlings were treated with epi-brassinolide (EBR) and brassinazole followed by the determination of the contents of chlorophyll (a+b) and soluble sugars, and the activity of dark reaction enzymes and the expression of the relevant genes. The results showed that chlorophyll (a+b) content increased by 7.4% under 0.1 μM EBR treatment for 48 h; furthermore, chlorophyll (a+b) content increased by 34% in detached leaves that were… More >

Abstract Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation and production. This study examined the effects of nanosilver on growth and development of rice root systems. Study results showed that fresh weight of rice belowground organs and root length both increased significantly by 5% and 25%, respectively, after rice radicles were treated with 2 ppm of nanosilver for three days. However, the H2O2 level reached its peak at 2 days from treatment, but the activities of the antioxidant enzymes CAT, APX, and GR… More >
