Agrobacterium tumefaciens-mediated transformation of Arabidopsis thaliana root explants by using kanamycin selection.
TLDR
A transformation procedure for Arabidopsis root explants based on kanamycin selection was established and an Agrobacterium tumor-inducing Ti plasmid carrying a chimeric neomycin phosphotransferase II gene (neo) was introduced, resulting in transformed seed-producing plants obtained with an efficiency between 20% and 80% within 3 months after gene transfer.

Control of Arabidopsis flower and seed development by the homeotic gene APETALA2.
TLDR
It is shown that in addition to its functions during flower development, AP2 activity is also required during seed development, and this suggests that AP2 represents a new class of plant regulatory proteins that may play a general role in the control of Arabidopsis development. Expand
Dual action of the active oxygen species during plant stress responses
TLDR
This review discusses the dual action of AOS during plant stress responses, which was first described in pathogenesis but has also recently been demonstrated during several abiotic stress responses. Expand
Modeling gene and genome duplications in eukaryotes.
TLDR
An evolutionary model that simulates the duplication dynamics of genes, considering genome-wide duplication events and a continuous mode of gene duplication is presented and it is shown that gene loss is strikingly different for large-scale and small-scale duplication Events and highly biased toward certain functional classes. Expand
Catalase is a sink for H2O2 and is indispensable for stress defence in C3 plants
TLDR
Leaf necrosis correlated with accumulation of oxidized glutathione and a 4‐fold decrease in ascorbate, indicating that catalase is critical for maintaining the redox balance during oxidative stress and may not be limited to peroxisomal H2O2 production. Expand
Small heat shock proteins and stress tolerance in plants.
TLDR
This review summarizes recent knowledge about plant sHsp gene expression, protein structure and functions and supports the hypothesis that these proteins play an important role in stress tolerance. Expand
The AP2 domain of APETALA2 defines a large new family of DNA binding proteins in Arabidopsis.
TLDR
It is shown that the AP2 domain containing or RAP2 (related to AP2) family of proteins is encoded by a minimum of 12 genes in Arabidopsis, and unlike other floral homeotic genes, AP2 is active during both reproductive and vegetative development. Expand
The ROOT MERISTEMLESS1/CADMIUM SENSITIVE2 Gene Defines a Glutathione-Dependent Pathway Involved in Initiation and Maintenance of Cell Division during Postembryonic Root Development
TLDR
It is shown that the G1-to-S phase transition requires an adequate level of GSH, which suggests the existence of a GSH-dependent developmental pathway essential for initiation and maintenance of cell division during postembryonic root development. Expand
The hidden duplication past of Arabidopsis thaliana
TLDR
It is shown that heavily degenerated block duplications that can no longer be recognized by directly comparing two segments because of differential gene loss, can still be detected through indirect comparison with other segments and strongly implies that Arabidopsis has undergone three, but probably no more, rounds of genome duplications. Expand
Dense genetic linkage maps of three Populus species (Populus deltoides, P. nigra and P. trichocarpa) based on AFLP and microsatellite markers.
TLDR
Linkage maps were constructed for Populus deltoides, P. nigra, and P. trichocarpa by analyzing progeny of two controlled crosses sharing the same female parent, using Amplified fragment length polymorphism (AFLP) markers to form four parental maps. Expand
