Tetraploidy in Enhances Drought Tolerance Synergistic Regulation of Photosynthesis, Phosphorylation, and Hormonal Changes.

Polyploidy varieties have been reported to exhibit higher stress tolerance relative to their diploid relatives, however, the underlying molecular and physiological mechanisms remain poorly understood. In this study, a batch of autotetraploid were identified from a natural seedling population, and these tetraploid seedlings exhibited greater tolerance to drought stress than their diploids siblings. A global transcriptome analysis revealed that a large number of genes involved in photosynthesis response were enriched in tetraploids under drought stress, which was consistent with the changes in photosynthetic indices including P, gs, T, C, and chlorophyll contents.

The Whole Genome Sequence of Strain YP04, a Pathogen that Causes Root Rot of American Ginseng.

was previously reported as a plant pathogen or an endophyte that is closely related to , a notoriously significant soilborne phytopathogen. Subsequent studies demonstrated the unique nature of , which was considered a distinct species that causes multiple symptoms on multiple hosts. It was recently identified as a pathogen that causes root rot of American ginseng.

Physiological and TMT-labeled proteomic analyses reveal important roles of sugar and secondary metabolism in Citrus junos under cold stress.

Citrus junos is a widely used citrus grafting rootstock in china because of its excellent tolerance to cold stress. However, the physiological and molecular mechanisms underlying this process remain unknown. In this study, physiological and tandem mass tag-based proteomic analyses were performed to elucidate the mechanism of the Citrus junos response to cold stress.

β-Cyanoalanine Synthase Regulates the Accumulation of β-ODAP via Interaction with Serine Acetyltransferase in .

β--Oxalyl-l-α,β-diaminopropionic acid (β-ODAP), found in at first, causes a neurological disease, lathyrism, when over ingested in an unbalanced diet. Our previous research suggested that β-ODAP biosynthesis is related to sulfur metabolism. In this study, β-cyanoalanine synthase (β-CAS) was confirmed to be responsible for β-ODAP biosynthesis via enzymatic analysis.

HS Regulation of Metabolism in Cucumber in Response to Salt-Stress Through Transcriptome and Proteome Analysis.

In a previous study, we found that HS alleviates salinity stress in cucumber by maintaining the Na/K balance and by regulating HS metabolism and the oxidative stress response. However, little is known about the molecular mechanisms behind HS-regulated salt-stress tolerance in cucumber. Here, an integrated transcriptomic and proteomic analysis based on RNA-seq and 2-DE was used to investigate the global mechanism underlying HS-regulated salt-stress tolerance.

HS Alleviates Salinity Stress in Cucumber by Maintaining the Na/K Balance and Regulating HS Metabolism and Oxidative Stress Response.

Salinity stress from soil or irrigation water can significantly limit the growth and development of plants. Emerging evidence suggests that hydrogen sulfide (HS), as a versatile signal molecule, can ameliorate salt stress-induced adverse effects. However, the possible physiological mechanism underlying HS-alleviated salt stress in cucumber remains unclear.

[Research on relationship between occurrence of root rot and changes of fungal communities in rhizosphere of Panax quinquefolius].

The root rot disease is a common disease during the cultivation of Panax quinquefolius. In order to provide some clues for solving the root rot disease of P. quinquefolius, the relationship between rhizosphere soil fungal communities and root rot of P.

Exogenous hydrogen peroxide reversibly inhibits root gravitropism and induces horizontal curvature of primary root during grass pea germination.

During germination in distilled water (dH(2)O) on a horizontally positioned Petri dish, emerging primary roots of grass pea (Lathyrus sativus L.) grew perpendicular to the bottom of the Petri dish, due to gravitropism. However, when germinated in exogenous hydrogen peroxide (H(2)O(2)), the primary roots grew parallel to the bottom of the Petri dish and asymmetrically, forming a horizontal curvature.
