Clonal plants combine sexual and clonal reproduction, which contribute differently to plant fitness. We investigated the consequence of natural selection on the two reproductive modes and the ecological factors that affect the reproductive modes of Eremosparton songoricum (Litv.) Vass. in order to understand the reproductive strategies of a clonal plant and the relationship between sexual and clonal reproduction. Morphological characteristics and biomass allocation patterns were m easured and compared at the clonal fragment level in two natural populations (riverside population A and hinterland population B) in the Gurbantunggut Desert, China. The flowering plant ratio, inflorescence number per plant, flower number per raceme, fruit number, mass of 100 seeds, root biomass, fruit biomass and ramet height were significantly higher, whereas fruit set, ramet density, rhizome biomass and length, and root number were significantly lower, in population A compared with those in population B. We estimated that the importance of clonal reproduction varies in two populations of E. songoricum, and the investment adjustment in the two reproductive modes may be based on cost required for each new plant to generate the more survival progeny in the plant life time.

A systematic knowledge of clonal integration is an important step in understanding the ecological implication of clonality. This study focuses on the performance of rhizomatous clonal plants under different situations and we proposed a hypothesis that clonal integration will significantly improve the disturbance and drought resistance ability and the competitive ability of Eremosparton songoricum. In 2009, the experiments were carried out in two natural populations. Rhizome was either severed (S) or not (I) in four treatments that include control (C), drought (D), disturbance (E), and competition (F). The biomass and the root-shoot ratio were compared in different experimental treatments. Under drought and disturbance treatments, the biomass of ramet with severed rhizome was significantly less than that of intact ramets, and both were lower than the samples under the control treatment. The differences in root-shoot ratio were opposite to the biomass in drought and disturbance treatments. The ramet biomass under the competition treatment had the same result as that under the drought and disturbance treatments. However, th e root-shoot ratio was highest in FS (competition treatment with severed rhizome) and lowest in FI (competition treatment with intact rhizome) under competition and control treatments. Our results suggest that clonal integration enhances the disturbance and drought resistance ability rather than the competitive ability of Eremosparton songoricum. This may be one of the various reasons why E. songoricum is distributed in sand dunes of droughty conditions with more disturbances but less competition. Integration proved to be important for the species occupying adverse patches. For E. songoricum, the existence of rhizome reduces the impact of environmental stress and improves the fitness in association with its location at the dune.

Compensatory effect is observed during the process of gradual adaptation of plants to abnormal environmental conditions; nitrogen fertilizer compensation has been extensively studied in rice production in recent years. However, metabolite production of the phenomenon has not been studied clearly. In this study, we used super hybrid early rice as the material and planted it in a barrel. Experiments were performed under two conditions of treatment, namely, CK (normal quantities of nitrogen fertilizer distribution at different growth stages) and T1 (nitrogen deficiency at tillering stage and compensatory application at young panicle differentiation stage). Liquid chromatography–mass spectrometry (LC–MS) was used to analyze metabolomics of rice leaves under conditions of nitrogen deficiency and compensation after the same period of CK treatment. Results showed that there was a significant difference between T1 and CK metabolites. The levels of stress-resistant substances and amino acid substitution product nitrogen deficiency increased under T1 treatment compared to CK, and the metabolites were consumed as the energy source. However, after compensation, the levels of the stress response products returned to normal, lipids were synthesized in large quantities, and fatty acid accumulation had increased.

The miR396 and growth-regulating factor (GRF) regulatory network is evolutionarily conserved among plant species. The orthologous GRF genes in rice were involved in regulating grain development, and targeted by miR396. However, there are still no more information about the involvement of miR396 and GRF genes in maize grain. In this article, RNA sequencing was performed on the developing maize kernels to analyze the dynamic profiles of miR396 and GRF genes and explore their possible regulatory roles during maize effective grain filling. Our results showed that GRF genes were also the conserved targets of miR396 in maize, according to computational prediction and validated by degradome sequencing. MiR396 expressed high and gradually declined with advancing maize grain filling, significant negatively correlated with its target GRF genes, which mostly increased continuously. Our test also provided a testimony of miR396-GRF network in different regulations between the development of maize embryo and endosperm by real-time quantitative PCR. And further analysis of expression pattern suggested that miR319, miR166, and RDR might interact with miR396-GRF network during grain development in maize. This study mainly provided a valuable foundation for future comprehensive analysis of miR396-GRF network, and further research work is needed to confirm the regulatory roles of miR396 and GRF genes during grain filling in maize.

Recent studies have demonstrated the higher likelihood of regeneration in forest gaps compared with the understory for the dominant species in pine-oak mixed forest. Here, we tested whether rodent seed predation or dispersal was beneficial for gap regeneration. We tracked the seed predation and dispersal of Quercus aliena var. acuteserrata and Pinus armandii using coded plastic tags in the forest understory close to gaps. Our results demonstrated that the proportions of initial buried seeds of both species were significantly more abundant in the forest understory compared with gaps. After seed caching, however, significantly lower proportions of the seeds of both species survived in the forest understory compared with gaps during the 30-day observation period. The final survival proportions of the seeds cached in the forest understory were lower than those cached in the gaps the next spring, which indicated that small rodents rarely retrieved scatter-hoarded seeds from forest gaps. Our findings suggest that rodent seed predation patterns contribute to the regeneration of the dominant species in gaps compared with the understory in a pine-oak mixed forest. In the study area, reforestation usually involves planting seedlings but direct sowing in forest gaps may be an alternative means of accelerating forest recovery and successional processes.
