CO2 regulator SLAC1 and its homologues are essential for anion homeostasis in plant cells
Guard-cell-specific expression of SLAC1 or its family members resulted in restoration of the wild-type stomatal responses, including CO2 sensitivity, and also in the dissipation of the over-accumulated anions, which suggest thatSLAC1-family proteins have an evolutionarily conserved function that is required for the maintenance of organic/inorganic anion homeostasis on the cellular level.
Ara6, a plant‐unique novel type Rab GTPase, functions in the endocytic pathway of Arabidopsis thaliana
Examination of green fluorescent protein (GFP)‐tagged proteins indicates that both Ara6 and Ara7 are distributed on a subpopulation of endosomes and suggests their roles in endosomal fusion.

The plant-specific Dof1 transcription factor is applied to improve nitrogen assimilation, the essential metabolism including the primary assimilation of ammonia to carbon skeletons to biosynthesize amino acids and other organic compounds involving nitrogen in plants, and improves growth under low-nitrogen conditions.
Dissection of Arabidopsis Bax Inhibitor-1 Suppressing Bax–, Hydrogen Peroxide–, and Salicylic Acid–Induced Cell Death Article, publication date, and citation information can be found at…
It is demonstrated that reactive oxygen species production induced by the ectopic expression of Bax was insensitive to the coexpression of AtBI-1, and the C-terminal hydrophilic region was interchangeable between animal and plant Bax inhibitors.

Direct genetic evidence is presented that the plant antiapoptotic protein AtBI-1 is biologically active in suppressing the mammalian Bax action in planta.
The ANGUSTIFOLIA gene of Arabidopsis, a plant CtBP gene, regulates leaf‐cell expansion, the arrangement of cortical microtubules in leaf cells and expression of a gene involved in cell‐wall formation
It is found that the abnormal arrangement of cortical microtubules in an leaf cells appeared to account entirely for the abnormal shape of the cells, and it was suggested that the AN gene might regulate the polarity of cell growth by controlling the arrangement of cortex MTs.
The role of NAD biosynthesis in plant development and stress responses.
Progress in the developmental and stress-related roles of genes associated with NAD biosynthesis in plants are covered and assessments of physiological impacts through the modulation of NAD and NADP biosynthesis are given.

It is suggested that CAK1At is a novel CAK-activating kinase that modulates the activity of CAK2At and CAK4At, thereby controlling CDK activities and basal transcription in Arabidopsis.

The plant Bax inhibitor plays a functional role in regulating cell death in the rice cell culture system through downregulated genes in suspension-cultured cells treated with the elicitor.
p-Chlorophenoxyisobutyric Acid Impairs Auxin Response in Arabidopsis Root1
The results suggest that PCIB impairs auxin-signaling pathway by regulating Aux/IAA protein stability and thereby affects the Auxin-regulated Arabidopsis root physiology.
