Expression patterns of class I KNOX and YABBY genes in Ruscus aculeatus (Asparagaceae) with implications for phylloclade homology

In Vivo and in Vitro Comparative Ultrastructural Studies of Ruscus Aculeatus L. Phylloclade Cells

A comparative study of the Ruscus aculeatus phylloclade cells structure and ultrastructure of plants belonging to the native habitat and in vitro culture are presented in the paper in order to establish an adequate protocol for ex situ conservation. In our experimental conditions no anomaly of the phylloclade cells ultrastructure has been observed. Some interesting modifications appeared at the...

YABBY polarity genes mediate the repression of KNOX homeobox genes in Arabidopsis.

The YABBY (YAB) genes specify abaxial cell fate in lateral organs in Arabidopsis. Loss-of-function mutants in two early-expressing YAB genes, FILAMENTOUS FLOWER (FIL) and YAB3, do not exhibit vegetative phenotypes as a result of redundancy. Mutations in these genes result in the derepression of the KNOX homeobox genes SHOOTMERISTEMLESS (STM), BREVIPEDICELLUS, and KNAT2 in the leaves and in the ...

Genome-Wide Study of YABBY Genes in Upland Cotton and Their Expression Patterns under Different Stresses

Members of the YABBY gene family, a small plant-specific family of genes, have been proposed to function in specifying abaxial cell fate. Although to date little has been learned about cotton YABBY genes, completion of the cotton genome enables a comprehensive genome-wide analysis of YABBY genes in cotton. Here, a total of 12, 12, and 23 YABBY genes were identified in Gossypium arboreum (2n = 2...

HLA Class I and Class II Genes Distribution of the Sistanis in Iran

Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...
