A point mutation in the promoter enhances callus formation and regeneration.

Unlabelled: Callus formation induced by auxin accumulation is considered the first step of in vitro plant regeneration. In , degradation of the Aux/IAA protein, IAA14, in response to auxin signaling, which activates the AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 along with a series of downstream transcription factors, also plays a critical role in this process. However, the specific mechanism by which auxin regulates callus formation remains unclear.

Effects of Graphene-Based Nanomaterials on Microorganisms and Soil Microbial Communities.

The past decades have witnessed intensive research on the biological effects of graphene-based nanomaterials (GBNs) and the application of GBNs in different fields. The published literature shows that GBNs exhibit inhibitory effects on almost all microorganisms under pure culture conditions, and that this inhibitory effect is influenced by the microbial species, the GBN's physicochemical properties, the GBN's concentration, treatment time, and experimental surroundings. In addition, microorganisms exist in the soil in the form of microbial communities.

Comparative genomics and bioinformatics approaches revealed the role of CC-NBS-LRR genes under multiple stresses in passion fruit.

Passion fruit is widely cultivated in tropical, subtropical regions of the world. The attack of bacterial and fungal diseases, and environmental factors heavily affect the yield and productivity of the passion fruit. The (CNL) gene family being a subclass of R-genes protects the plant against the attack of pathogens and plays a major role in effector-triggered immunity (ETI).

Screening and isolation of cold-adapted cellulose degrading bacterium: A candidate for straw degradation and genome sequencing analysis.

Degradation of crop straw in natural environment has been a bottleneck. There has been a recent increase in the exploration of cold-adapted microorganisms as they can solve the problem of corn straw degradation under low temperatures and offer new alternatives for the sustainable development of agriculture. The study was conducted in low-temperature (10°C) and high-efficiency cellulose-degrading bacteria were screened using carboxymethyl cellulose (CMC) selection medium and subjected to genome sequencing by the third-generation Pacbio Sequl and the second-generation Illumina Novaseq platform, and their cellulase activity was detected by 3,5-dinitrosalicylic acid (DNS) method.

Construction of a high-density genetic linkage map and QTL analysis of morphological traits in an F1 × hybrid.

Unlabelled: Apple is considered the most commonly grown fruit crop in temperate regions that brings great economic profits to fruit growers. Dwarfing rootstocks have been extensively used in apple breeding as well as commercial orchards, but the molecular and genetic basis of scion dwarfing and other morphological traits induced by them is still unclear. At present, we report a genetic map of  ×  with high density.

Comparative analysis of transcriptomic profiling to identify genes involved in the bulged surface of pear fruit ( Rehd. cv. Yuluxiangli).

Unlabelled: Pear ( spp.) belongs to the genus , in the family Rosaceae. Some varieties of pear fruit exhibit bulged surface, which seriously affects the quality and commodity value of the pear fruit.

Systematic analysis of the genes in six Rosaceae genomes and their roles in stress response in Chinese pear ().

OVATE family proteins (OFPs) are the plant-specific transcription factors, and have significant functions in regulating plant growth, development and resistance. The genes have been investigated in several plants, but they still lack a systematic analysis of genes in Chinese pear and some other five Rosaceae genomes. Here, 28 were identified within Chinese pear and compared them with those of other five Rosaceae genomes.
