Although the relationship between basal (BT), acquired (AT) and maintenance of acquired thermotolerace (MT) has been illustrated in a heat resistant tomato genotype and sensitive tomato genotypes, whether more resistant and sensitive tomato genotypes are satisfied with the rule and the relationships of antioxidant enzymes (AE) activity in three kinds of thermotolerance are not known. Here, we have observed the intension of three kinds of tomato thermotolerance is associated with AE activities. The priming and enhancement of thermotolerance was temperature dependent with stronger thermotolerance priming by moderately high temperatures than warmer temperatures. Interestingly, AE activity also showed significantly higher in seedlings under moderately high temperature than ones at warmer temperatures. While after the first optimized priming of different high temperatures combined with secondary priming for a reasonable period, AE activity and its thermotolerance further enhanced. Surprisingly, these optimized acclimation treatments showed no difference in AE activity and MT intension, suggesting that secondary priming could supply gaps produced by the first priming of warmer high temperatures, through enhancing AE activity. Additionally, the basal heat resistant genotypes showed stronger AE activity and thermotolerance (AT and MT) than sensitive genotypes. Results from this study will provide insights into understanding mechanism behind regulating tomato thermotolerance and facilitate the development of heat tolerant cultivars.

Melanophilin (MLPH) gene has been characterized as one of the candidate genes for coat colour dilution in human, mice and dog, but little is known about it in goat. Part of the 5’UTR (650bp,JQ743911) was sequenced leading to identify four polymorphic loci (g.G426A, g.A570G, g.G592T and g.612-614insCTC). The genetic diversity was analysed in 120 individuals of four breeds of goat. The possible transcription factors in the four loci were mined by online tools. The results show that the four loci were in Hardy-Weinberg equilibrium (P>0.05) and there was a significant difference in gene sequence between Jining Grey (JN) and Leizhou Black (LZ) breeds (P < 0.05). JN has the highest allele frequency of A, A, G and insertion CTC at the four loci; and LZ has the highest allele frequency of G, G, T and deletion CTC. JN has the lowest effective allele number and the lowest value of Shannon I at the four polymorphic loci. LZ has the highest effective allele number and the highest Shannon I at the four polymorphic loci. Moreover, JN has the highest Fst and Gst (0.08 and 0.12, respectively) and the lowest Nm (2.80) compared to LZ. In silico analysis showed that the possible transcription factors having a potential binding site in the sequence consisting of A, A and G and insertion CTC in the four polymorphic loci of 5’UTR of MLPH gene were BRN2, CCAT,P, STAT and USF. The sequence consisting of G, G, T and deletion CTC in the 5’UTR region of MLPH formed the possible binding sites of MyoD, c-Myb, v-Myb, AP-1, USF and NKX25. It could be concluded that JN has different gene sequence in the four mutation sites of 5’UTR of MLPH compared to LZ and the mutation caused the variation of possible transcription factors that may play a role in the MLPH gene expression regulation; so JN has dilute, ashen and grey coat colours and LZ is of solid black colour.

Phosphorus as a major nutrient element in water ecosystems is a key factor affecting algae growth in rivers. This paper adopts the sequential extraction method for phosphorus fractionation to study the distribution of phosphorus forms in riparian soils and peripheral river sediments, then to analyze the relationship between different phosphorus forms and their significance within a watershed environment. The results show that: 1) the contents of NH₄Cl-P, BD-P, and HCl-P in riparian soils are more widespread than those in river sediments, 2) the distribution patterns of phosphorus fractions in different catchments of Jianxi Basin are varied for soil and sediment, and 3) the ratio of BAP/TP is the highest in Chongyangxi catchment and the lowest in Songxi catchment. Phosphorus in riparian soils is mainly affected by agricultural activities, significantly for NaOH-P and HCl-P. And phosphorus forms in sediments are obviously affected by domestic sewage. The phosphorus contents and fractions in riparian soils change more significantly than those in river sediments.

To understand physiological acclimation of psammophyte to repeated soil drought and rewatering, two psammophytes (Setaria viridis and Digitaria ciliaris) were subjected to three cycles of soil drought and rewatering. The response process of leaf relative water content (RWC), membrane permeability, lipid peroxidation, gas exchange characteristics, antioxidant enzymes, soluble protein, and free proline was examined. Leaf RWC, the net photosynthesis rate, stomatal conductance, and water use efficiency decreased, while membrane permeability, lipid peroxidation, intercellular CO₂ concentration, soluble protein, and free proline increased during three soil drought periods for both psammophytes. These physiological characteristics were recovered to the control levels following rewatering for 4 days. However, activities of SOD, CAT, and POD were induced continuously under soil drought conditions, and remained higher than those in the control throughout the whole experiment period, which agrees with our hypothesis that drought hardening activates defensive systems of both psammophytes continuously. Decreasing level of leaf RWC and increasing levels of leaf membrane permeability and lipid peroxidation were suppressed with increasing the number of drought cycles, suggesting that drought hardening alleviates damages of both psammophytes and improves their drought tolerance and acclimation to soil drought conditions in the future. Additionally, the photosynthesis decreased more slowly in the subsequent drought cycles than in the first cycle, allowing both psammophytes to maximize assimilation in response to repeated soil drought conditions. Thus, both psammophytes acclimatize themselves to repeated soil drought.

As a member of tyrosinase-related family, tyrosinase-related protein-1 (TYRP1) has been reported to play an important role in melanin biosynthetic pathway in some species, but little is known about its role in goat. In this study, almost complete goat TYRP1 gene (17554 bp, HMO70243) encompassing complete CDS was identified, the coding region amounting to 1614 bp, distributed in 7 exons (2-8), and intron 5 was found to possess GC-AG as its splice sites. Dozens of SNPs as well as simple sequence repeat (SSR) motifs were detected in goat TYRP1 gene, in which 4 SSR motifs in intron 5 are combined in a tandem. Correlation analysis showed the allele A to be advantageous compared to C at site g.1263A>C and allele C compared to T at g.1428C>T, implyimg that haplotype AC is in favour of eumelanin biosynthesis, and haplotype CC is in favour of pheomelanin formation.Marked deficiency of heterozygotes occurred in Nanjiang Yellow Goat Black strain and Nanjiang Yellow Goat Fast Grow strain, indicating the high inbreeding in both strains.

Sonneratia alba (S. alba) is a mangrove species grown in brackish water of tropical and subtropical regions. Due to its unique environment, it has evolved various mechanisms for modulating salt and metal levels. In order to find the genes connected with bioaccumulation of metals, the root transcriptome annotation of Sonneratia alba was analyzed and a new metallothionein (MT) gene was cloned. Sequence analysis found that the new MT gene belongs to type 3 MT, which is mostly expressed in roots. A simple and efficient method was used to express the type 3 MT of S. alba (SaMT3) by transforming the recombinant expression vector pET15b-SaMT3 into Escherichia coli (E. coli) Rosetta-gami and induction with the optimal conditions of 500 μM Isopropyl β-D-1-thiogalactopyranoside (IPTG) at 24ºC for 12 h. OD₆₀₀ of E. coli cells expressing His fused SaMT3 protein after treated with 500 μM Cu²⁺ or 500 μM Pb²⁺ for 12 h can reach 1.01 or 0.98, while OD₆₀₀ of control cells expressing His-tag can reach only 0.81 or 0.75. Both control cells and the cells expressing SaMT3 accumulated metals. Cells expressing SaMT3, however, accumulated more Pb²⁺ and Cu²⁺ (more than two times) than control cells. In vivo, real-time PCR showed that the SaMT3 transcript was induced significantly when stimulated with 250 μM, 500 μM, or 1,000 μM Cu²⁺ or Pb²⁺ for 24 h and 48 h. Taken together, the expression of SaMT3 can increase Cu²⁺ and Pb²⁺ resistance and binding capacity of E. coli.
