Ambient temperature induces the hypocotyl elongation of seedling, called as thermomorphogenesis. In this issue, Deng et al. found that the canonical bHLH transcriptional factor PIF7 mediates the seedling thermomorphogenesis in the model plant Arabidopsis. During this process, an essential regulator AFP2, which is previously reported to be associated with abscisic acid signal, interacts with PIF7, thus fine turns the transcriptional activity, subsequently precisely modulates downstream auxin biosynthesis to coordinate hypocotyl elongation.

Abstract Carotenoids represent a large group of mainly red, orange, and yellow natural metabolites mainly involved in regulation of many metabolic processes. Carotenoids are beneficial for human health. Current study describes the importance, chemical composition and functioning of carotenoids. It is well known that carotenoids support pigments acting in light absorbance mechanisms during photosynthesis, and are known to protect the chlorophyll molecules from oxidative stress and reactive oxygen species (ROS) damage. Carotenoids are involved in signaling processes in plants, responses to environmental stresses, pollination, germination and reproduction, and development regulation. As nutrients of strong antioxidant activity that is primarily linked to… More >

Abstract Tristeza is a devastating viral disease in all the citrus growing countries throughout the world and has killed millions of citrus trees in severely affected orchards. The citrus species grafted on sour orange rootstock are affected
by this disease. Predominantly, the sweet orange, grapefruit and lime trees grafted on sour orange exhibit severe
symptoms like quick decline, vein clearing, pin holing, bark scaling and degeneration leading to variable symptoms. Symptomatic expression of Citrus tristeza virus (CTV) in different hosts has been attributed to virus isolates
which are from severe to mild. Different serological and molecular assays have been deployed to… More >

Abstract Seed germination or dormancy status is strictly controlled by endogenous phytohormone and exogenous environment signals. Abscisic acid (ABA) is the important phytohormone to suppress seed germination. Ambient high temperature (HT) also suppressed seed germination, or called as secondary seed dormancy, through upregulating ABI5, the essential component of ABA signal pathway. Previous result shows that appropriate nitric oxide (NO) breaks seed dormancy through triggering S-nitrosoglutathion reductase (GSNOR1)-dependent S-nitrosylation modification of ABI5 protein, subsequently inducing the degradation of ABI5. Here we found that HT induced the degradation of GSNOR1 protein and reduced its activity, thus accumulated more reactive nitrogen species (RNS) to… More >

Abstract Ambient temperature induces the hypocotyl elongation of seedling, called as thermomorphogenesis. It has been reported that the bHLH transcriptional factor PIF7 acts as the critical component to modulate plant thermomorphogenesis, but the underlying mechanism remains elusive. The phytohormone abscisic acid (ABA) suppresses the hypocotyl elongation under high temperature (HT) stress. As the ABI5 binding protein, AFP2 acts as the negative factor to control ABA signaling. In this study, we first identified AFP2 as the interaction protein of PIF7 in vitro and in vivo. Phenotype analysis revealed that overexpressing AFP2 reduced the hypocotyl elongation, while loss-of-function afp2 mutant showed longer hypocotyl… More >

Abstract Leaf color mutants are ideal materials for studying many plant physiological and metabolic processes such as photosynthesis, photomorphogenesis, hormone physiology and disease resistance. In this study, the genetically stable yellow-green leaf mutant ygl16 was identified from mutated “Xinong 1B”. Compared with the wild type, the pigment concentration and photosynthetic capacity of the ygl16 decreased significantly. The ultrastructural observation showed that the distribution of thylakoid lamellae was irregular in ygl16 chloroplasts, and the grana and matrix lamellae were blurred and loose in varied degrees, and the chloroplast structure was disordered, while the osmiophilic corpuscles increased. The results of the genetic analysis… More >

Abstract Rice ratooning, or the production of a second rice crop from stubble after the harvest of the main crop, is considered
to be a green and resource-efficient rice production system. The present study was conducted to examine variance in
amylose content (AC), grain morphology, crystal structure, and thermal properties of starch between main- and
ratoon-season rice of seven varieties. Ratoon-season rice grains had higher ACs and significantly lower transition
gelatinization temperatures (To, Tp, and Tc) than did main-season rice grains. The relative crystallinity and lamellar
peak intensity of ratoon-season rice starch were 7.89% and 20.38% lower, respectively, than those of… More >

Abstract Melon (Cucumis melo), belonging to the Cucurbitaceae family, is a globally important economic crop. GRAS (GAI, RGA, SCR) genes, which are a type of transcription factor, play a critical role in plant growth and development, including processes such as radial root patterning, light signalling, abiotic/biotic stress, axillary shoot meristem formation, and phytohormone (gibberellin) signal transduction. In this study, the GRAS family in melon was analysed comprehensively with respect to chromosomal location, motif prediction, gene structure, and expression pattern. A total of 37 GRAS genes were first identified in melon, after which a phylogenetic tree was built with the GRAS genes… More >

Abstract
The hyperaccumulator Sedum alfredii Hance (S. alfredii) may be employed for zinc (Zn) and cadmium (Cd)-polluted soil remediation. However, the low phytoremediation efficiency, related to the low biomass production, limits its use with that purpose. In this experiment, nitrogen (N), phosphorus (P), and potassium (K) fertilizers, and organic manure were applied to investigate the phytoremediation ability of S. alfredii. Hydroponic and pot experiments were conducted using Zn-Cd polluted soil. The hydroponic experiment indicated that appropriate fertilizer application could increase (p < 0.05) the amount of accumulated Zn and Cd in S. alfredii. When N supply ranged from 0.5 to 2.5… More >

Abstract Greenhouse vegetable cultivation (GVC) is an example of intensive agriculture aiming to increase crop yields by
extending cultivation seasons and intensifying agricultural input. Compared with cropland, studies on the effects

Abstract Soil fungi are extremely important for maintaining soil health and plant production in agricultural systems. Currently, the effect of continuous cropping of sweet potato on soil fungal communities and physiochemical parameters has not been well documented. In the present study, four sweet potato fields consecutively

fungal community composition, whereas fungal diversity was almost unchanged. Ascomycota and Basidiomycota

Abstract Soil nutrients are commonly heterogeneously distributed and earthworms are one of the most common soil organisms. While effects of both soil nutrient heterogeneity and earthworms have been well studied, their interactive effect on plant community productivity has rarely been tested. In a greenhouse experiment, we constructed experimental plant communities by sowing seed mixtures of four grasses, two legumes and two forbs in either a heterogeneous soil consisting of low and high nutrient soil patches or a homogeneous soil where the low and high nutrient soil patches were evenly mixed. The earthworm Eisenia fetida was either added to these soils or… More >
