Rab small GTPases regulate vesicle transport in eukaryotes by interacting with various effectors. Guanine nucleotide-exchange factor (GEF) catalyzes the transition from inactive GDP-bound Rab to active GTP-bound Rab. The existence of several GDP-bound intermediates containing the Arabidopsis

Many GTPases regulate intracellular transport and signaling in eukaryotes. Guanine nucleotide exchange factors (GEFs) activate GTPases by catalyzing the exchange of their GDP for GTP. Here we present crystallographic and biochemical studies of a GEF reaction with four crystal structures of
GNOM-LIKE 2, encoding an adenosine diphosphate-ribosylation factor-guanine nucleotide exchange factor protein homologous to GNOM and GNL1, is essential for pollen germination in Arabidopsis.

In flowering plants, male gametes are delivered to female gametophytes by pollen tubes. Although it is important for sexual plant reproduction, little is known about the genetic mechanism that controls pollen germination and pollen tube growth. Here we report the identification and characterization

Rho family small GTPases are signaling switches controlling many eukaryotic cellular processes. Conversion from the GDP- to GTP-bound form is catalyzed by guanine nucleotide exchange factors (GEFs). Rho GEFs in animals fall into two structurally distinct classes containing DH and DOCKER catalytic
Multifaceted Roles of the Ras Guanine-Nucleotide Exchange Factor ChRgf in Development, Pathogenesis, and Stress Responses of Colletotrichum higginsianum.

The infection process of Colletotrichum higginsianum, which causes a disease of crucifers, involves several key steps: conidial germination, appressorial formation, appressorial penetration, and invasive growth in host tissues. In this study, the ChRgf gene encoding a Ras guanine-nucleotide exchange
A guanine nucleotide exchange factor for Rab5 proteins is essential for intracellular transport of the proglutelin from the Golgi apparatus to the protein storage vacuole in rice endosperm.

Rice (Oryza sativa) glutelins are synthesized on the endoplasmic reticulum as a precursor, which are then transported via the Golgi to protein storage vacuoles (PSVs), where they are proteolytically processed into acidic and basic subunits. The glutelin precursor mutant6 (glup6) accumulates

Arabidopsis RabE1d subclass plays important plant-specific functions in plant growth and development, response to ethylene and defence to plant pathogen, besides their basic cellular role in membrane trafficking. In this study, we present the expression, purification, and characterization of the
Molecular basis of the ribulose-1,5-bisphosphate carboxylase/oxygenase activase mutation in Arabidopsis thaliana is a guanine-to-adenine transition at the 5'-splice junction of intron 3.

Analysis of the ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activase gene and gene products from Arabidopsis thaliana wild-type plants and the Rubisco activase-deficient mutant strain showed that the rca mutation caused GT to be changed to AT at the 5'-splice junction of intron 3 in
Isolation of cDNAs encoding guanine nucleotide-binding protein beta-subunit homologues from maize (ZGB1) and Arabidopsis (AGB1).

We have isolated cDNAs from maize (ZGB1) and Arabidopsis (AGB1) encoding proteins homologous to beta subunits of guanine nucleotide-binding protein (G protein). The predicted ZGB1 and AGB1 gene products are 76% identical to each other and 41% or more identical to animal G protein beta subunits. Both

Rop/Rac small GTPases are central to diverse developmental and cellular activities in plants, playing an especially important role in polar growth of pollen tubes. Although it is established that a class of plant-specific RopGEFs promotes the activity of Rop/Rac through the catalytic PRONE

Modified nucleosides in tRNAs are critical for protein translation. N1-methylguanosine-37 and N1-methylinosine-37 in tRNAs, both located at the 3'-adjacent to the anticodon, are formed by Trm5. Here we describe Arabidopsis thaliana AtTRM5 (At3g56120) as a Trm5 ortholog. Attrm5 mutant plants have

Phosphatidic acid (PA) forms part of plant lipid metabolism and is a signalling molecule used in response to various external stresses. Guanine nucleotide exchange factors (GEFs) activate small GTPase ROPs, serving as molecular switches in a wide range of signalling pathways. However, the

Abscisic acid (ABA) plays essential roles in plant development and responses to environmental stress. ABA induces subcellular translocation and degradation of the guanine nucleotide exchange factor RopGEF1, thus facilitating ABA core signal transduction. However, the underlying mechanisms for

The small GTPases of the Rho family play a key role in actin cytoskeletal organization. In plants, a novel Rho subfamily, called ROP (Rho of plants), has been found. In Arabidopsis, 12 ROP GTPases have been identified which differ mainly at their C-termini. To test the localization of two members of
