Plant Breeder's Envelope

Targeting proteins to the plant nuclear envelope.

The nuclear envelope and the nuclear pore are important structures that both separate and selectively connect the nucleoplasm and the cytoplasm. The requirements for specific targeting of proteins to the plant nuclear envelope and nuclear pore are poorly understood. How are transmembrane-domain proteins sorted to the nuclear envelope and nuclear pore membranes? What protein-protein interactions...

The plant nuclear envelope in focus.

Recent progress in understanding the plant NE (nuclear envelope) has resulted from significant advances in identifying and characterizing the protein constituents of the membranes and nuclear pores. Here, we review recent findings on the membrane integral and membrane-associated proteins of the key domains of the NE, the pore domain and inner and outer NEs, together with information on protein ...

Advantages and Disadvantages of Participatory Plant Breeding (PPB) in Iran: A Study Based on Breeders' Perceptions

The purpose of this study was to investigate the advantages and disadvantages of Participatory Plant Breeding (PPB). Seventy-six breeders were randomly selected from among 95 breeders who were working at the Seed and Plant Improvement Institute, Karaj, Iran. Data were collected by a questionnaire as the main data collection instrument. The face and content validity of the questionnaire was appr...

Update on the Plant Nuclear Envelope and Nuclear Pore Dynamics of the Plant Nuclear Envelope and Nuclear Pore

The nucleus is the most prominent compartment of any eukaryotic cell and home to its genetic information. The nucleoplasm is surrounded by a double membrane system, the nuclear envelope (NE). The outer nuclear membrane (ONM) and the inner nuclear membrane (INM) are separated by the perinuclear space (or periplasmic space; Hetzer et al., 2005). The lipid bilayer of the ONM is continuous with the...
