Effects of microbial agent application on the bacterial community in ginger rhizosphere soil under different planting years.

Ginger is one of the important spice crops in the world. Due to the prevalence of ginger wilt disease and the lack of effective prevention and control methods, the planting area, total production and value have declined sharply, which have become a key factor restricting ginger industry development in China. Understanding the influence of microbial agents on the rhizosphere microbiota of ginger will facilitate developing novel technologies for the prevention and control of ginger wilt disease.

Phylogenomics and plastome evolution of (Fabaceae).

Introduction: L. is the third largest genus in Fabaceae and includes economically important species that are used for indigo dye-producing, medicinal, ornamental, and soil and water conservation. The genus is taxonomically difficult due to the high level of overlap in morphological characters of interspecies, fewer reliability states for classification, and extensive adaptive evolution.

CLAVATA1-type receptor-like kinase CsCLAVATA1 is a putative candidate gene for dwarf mutation in cucumber.

Dwarf mutations have played vital roles in elucidating the regulatory molecular mechanisms of plant height. In this study, we identified a mutant named Csdw, whose mutagenesis was induced by ethyl methyl sulfonate in cucumber, and this mutant exhibited a dwarf phenotype with a reduced internode length because of the reduction of cell division in the main stem. The dwarf phenotype of Csdw could be partially rescued through GA application, and endogenous GA levels from the stem of Csdw decreased distinctly.

CsMYB36 is involved in the formation of yellow green peel in cucumber (Cucumis sativus L.).

A yellow green peel mutant (ygp) in cucumber was caused by a mutation in Csa2G352940 encoding MYB36 transcription factor. Peel color is one of the important agronomic traits of cucumber (Cucumis sativus L.).

[Cloning and Evolutionary Analysis of Homologous Sequences of CYP86MF Gene in Cruciferae.].

In order to direct the construction of plant germplasms by elucidating the relatives among plants at the level of gene, CYP86MF gene analogues from 11 species of 6 genera in Cuciferae were respectively obtained by PCR strategy using gene specific primers designed from conserved regions of CYP86MF gene reported. Sequence comparisonindicated that the similarities among the genes at nucleotide level were over 80%, and the similarities at amino acid level remained above 70%. The differences between the genes at nucleotide and amino acid level between species were 1.
