(Nees) Kuntze is an important plant used to process the traditional Chinese herbal medicines "Qingdai" and "Nanbanlangen". The key active ingredients are indole alkaloids (IAs) that exert antibacterial, antiviral, and antitumor pharmacological activities and serve as natural dyes. We assembled the genome at the chromosome level through combined PacBio circular consensus sequencing (CCS) and Hi-C sequencing data.

Evidence suggests that the biosynthesis of indigo alkaloids in plants occurs via the shikimate pathway. The enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) is involved in plant metabolism; however, its underlying putative mechanism of regulating the production of indigo alkaloids is currently unknown.

Taking super-rice Liangyoupeijiu as test material, and by the method of two-dimensional gel electrophoresis (2-DE), this paper studied the changes in the leaf and grain proteomics of the variety at its late growth stage under different levels of nitrogen fertilization (1/2 times of normal nitrogen level, 20 mg x L(-1); normal nitrogen level, 40 mg x L(-1); 2 times of normal nitrogen level, 80 mg x L(-1)), with the biological functions of 16 leaf proteins, 9 inferior grain proteins, and 4 superior grain proteins identified and analyzed. Nitrogen fertilization could affect and regulate the plant photosynthesis via affecting the activation of photosynthesis-related enzymes and of CO2, the light system unit, and the constitution of electron transfer chain at the late growth stage of the variety. It could also promote the expression of the enzymes related to the energy synthesis and growth in inferior grains.

A total of significantly different 20 protein spots were obtained, among which, eight protein spots were indentified, being of ATP synthase, alpha tubulin, cell division protein, glyceraldehydephosphate dehydrogenase, and ACC oxidase, respectively. The expression abundance of all identified proteins was up-regulated, except for ACC oxidase which was down-regulated.

By the method of ELASA, this paper measured the ABA/ZRs ratio in wheat flag leaf at the relative steady phase (RSP), end steady phase (ESP) and sharply descending phase (SFP) of chlorophylls. The ABA, ZRs and their mixture were led to the transpiration current of plant to measure the changes of photosynthesis rate at these three phases. The results showed that the ABA/ZRs ratio in flag leaf was 4.

A field trial on the wheat root activity, chlorophyll content and photosynthetic rate showed that the decline of root activity was earlier and faster than that of flag leaf chlorophyll content and photosynthetic rate, and there was a positive correlation between root activity and leaf photosynthetic rate (r = 0.8006). Topdressing nitrogen fertilizer at elongation stage could obviously improve root activity and photosynthetic rate, decrease leaf ABA content, increase ZRs content and SOD activity, and delay the peak value of MDA for 8-10 days, which suggested that the variation of root activity was closely related to the senescence of flag leaf.

Objective: To identify and analyse the different species, same species in different regions and confusion species.
Method: Near-infrared diffuse reflectance spectrometry was used.
Result: Clustering analysis showed that clustering relations were far among different Gryllotalpa species and close among the same species from different regions, and there were close relations among the same species from near regions and between Teleogryllus emmus and G.
