Eukaryotes are often subjected to different kinds of stress. In order to adjust to such circumstances, eukaryotes activate stress–response pathways and regulate gene expression. Eukaryotic gene expression consists of many different steps, including transcription, RNA processing, RNA transport, and translation. In this review article, we focus on both transcriptional and post-transcriptional Author: Koh Nakayama, Naoyuki Kataoka. Abstract. Tuberization in potato is controlled by hormonal and environmental signals. Ca 2+, an important intracellular messenger, and calmodulin (CaM), one of the primary Ca 2+ sensors, have been implicated in controlling diverse cellular processes in plants including tuberization. The regulation of cellular processes by CaM involves its interaction with other proteins.
Arabidopsis calmodulin isoforms CaM2/3/5 and CaM7 negatively regulate Ca 2+ conductivity during heat shock by binding to an atypical IQ motif in cyclic nucleotide-gated ion channel 6.

Brassinosteroids (BRs) are a group of polyhydroxylated plant steroid hormones that are crucial for many aspects of a plant’s life. BRs were originally characterized for their function in cell elongation, but it is becoming clear that they play major roles in plant growth, development, and responses to several stresses such as extreme temperatures and by: 3.
Abstract. Potato Homeobox 15 (POTH15) is a KNOX-I (Knotted1-like homeobox) family gene in potato that is orthologous to Shoot Meristemless (STM) in e numerous reports on KNOX genes from different species, studies in potato are limited. Here, we describe photoperiodic regulation of POTH15, its overexpression phenotype, and identification of its potential targets in potato Cited by: 2. Nature and Cell.

Ing the expression of PCM 1 alters growth and development in potato plants. Key words: Solanum tuberosum L., calmodulin, tuberization and transgenic plants. Introduction Calmodulin, a Ca2+-binding regulatory protein is known to play a pivotal role in Ca 2 + signaling in eukaryotes.
Calmo-dulin is considered to be multifunctional because of its ability. The expression of different calmodulin isoforms (PCM1, 5, 6, and 8) was studied in transgenic plants.
Among the four potato calmodulin isoforms, only the expression of PCM1 mRNA was altered in transgenic plants, while the expression of other isoforms was not significantly by: Get this from a library.
Regulated expression of a calmodulin isoform alters growth and development in potato. [B W Poovaiah; United States. National Aeronautics and Space Administration.;]. The expression of different calmodulin isoforms (PCM1, 5, 6, and 8) was studied in transgenic plants.

Among the four potato calmodulin isoforms, only the expression of PCM 1 MRNA was altered in transgenic plants, while the expression of other isoforms was not significantly altered.
Western analysis revealed increased PCM 1 protein in transgenic plants, indicating that the expression of both MRNA and protein are altered in transgenic plants. In an earlier report we found that upregulated expression of one CaM isoform (PCM1) resulted in increased growth and apical dominance in pot similar to the results of brassinosteroid Cited by: The induced expression of at least some of these calmodulin-related genes is mediated by a rise in cytosolic Ca 2+ in response to the external stimulus .

The importance of calcium and calcium-binding proteins such as calmodulin in plant growth and development as well as plant response to environmental stimuli has been recognised for some time.
However, it is only recently that the underlying mechanisms have begun to be unravelled. A variety of intracellular calcium signatures have been observed in response to various stimuli.
However, how Cited by: that its expression is developmentally regulated . Potato calmodulin mRNA is highly expressed in the stolon tip, and its expression decreases during tuber development.
To study the genomic organization and expression of calmodulin genes, we have characterized different calmodulin clones from potato.
