Transgenic Arabidopsis Thaliana

Owing to their sessile nature, plants are easily affected by various extenal factors. Among those, drought and salinity are considered as the most common stresses, which often pose a threat to plant growth and development. Major effects of the drought and salinity are interconnected and drive similar series of molecular changes in plants.

It is well known that WRKY transcription factors play important roles in plant growth and development, defense regulation and stress responses. This suggested that the overexpression of CkWRKY33 led to an enhanced drought-stress tolerance in transgenic A. thaliana. Thus, CkWRKY33 may act as a positive regulator involved in the droughtstress responses in Caragana korshinskii.

Hypoxia induced by flooding causes significant losses to crop production almost every year. However, the molecular network of submergence signaling pathway is still poorly understood. According to previous studies, transgenic plants overexpressing the WRKY33 gene showed enhanced resistance to submergence stress.

Auxins play key roles in the phytohormone network. Early auxin response genes in the AUX/ IAA, SAUR, and GH3 families show functional redundancy, which makes it very difficult to study the functions of individual genes based on gene knockout analysis or transgenic technology.

As global warming becomes increasingly severe, it is urgent that we enhance the heat tolerance of crops. We previously reported that Arabidopsis thaliana PHOSPHOINOSITIDE-SPECIFIC PHOSPHOLIPASE C9 (AtPLC9) promotes heat tolerance.

The NAC (NAM, ATAF1/ATAF2, and CUC2) transcription factors belong to a large family of plantspecific transcription factors in monocot and dicot species. These transcription factors regulate the expression of stress tolerance-related genes that protect plants from various abiotic stresses, including drought, salinity, and low temperatures.

Drought stress can severely affect plant growth and crop yield. The cloning and identification of drought-inducible promoters would be of value for genetically-based strategies to improve resistance of crops to drought.

The main objective in this study was to analyze the salinity and drought tolerance of Arabidopsis thaliana overexpressing GmNAC019 using several physiological parameters. The obtained results are expected to provide more information on the role of GmNAC019 and its potential for improving transgenic crops’ performance under drought and salinity conditions.

Drought is by far the most important environmental factor contributing to yield losses in crops, including soybeans [Glycine max (L.) Merr.]. To address this problem, a gene that encodes an osmotin-like protein isolated from Solanum nigrum var. americanum (SnOLP) driven by the UBQ3 promoter from Arabidopsis thaliana was transferred into the soybean genome by particle bombardment.

Promoters play important roles in gene expression and function. There are three basic types of promoters: Constitutive, specific, and inducible. Constitutive promoters are widely used in genetic engineering, but these promoters have limitations. Inducible promoters are activated by specific inducers.

Extensive studies using the model system Arabidopsis thaliana to elucidate plant defense signaling and pathway networks indicate that salicylic acid (SA) is the key hormone triggering the plant defense response against biotrophic and hemi-biotrophic pathogens, while jasmonic acid (JA) and derivatives are critical to the defense response against necrotrophic pathogens.

Plants have evolved light sensing mechanisms to optimally adapt their growth and development to the ambient light environment. The COP1/SPA complex is a key negative regulator of light signaling in the well-studied dicot Arabidopsis thaliana.

Vacuolar invertases (VINs) have been reported to regulate plant growth and development and respond to abiotic stresses such as drought and cold. With our best knowledge, the functions of VIN genes little have been reported in tea plant (Camellia sinensis L.). Therefore, it is necessary to develop research in this field.

Abiotic stresses are serious threats to plant growth, productivity and result in crop loss worldwide, reducing average yields of most major crops. Although abiotic stresses might elicit different plant responses, most induce the accumulation of reactive oxygen species (ROS) in plant cells leads to oxidative damage.

Galactinol synthase (GolS) has been known to play a key role in raffinose biosynthesis by catalysing the formation of galactinol. The GolS gene family has been recently identified in various plant species. Among them, many individual GolS genes have been reported to function in plant stress tolerance. In this study, we reported the construction of transgenic Arabidopsis overexpressing a soybean GolS gene, GolS2. There were no significant differences in the phenotypes of the transgenic and control plants during normal physiological conditions.

Polyphenol oxidase (PPO) enzymes are ubiquitous in plant kingdom and catalyze the oxidation of phenols to highly reactive quinones. The PPO gene plays an important role in plant defense mechanisms against biotic and abiotic stresses but the regulation of PPO promoter in stresses remains unclear.

Among grain legumes, peas (Pisum sativum L.) are highly sensitive to salt stress. Acclimatization of plants to such conditions is mandatory. We provide improved salt stress tolerance response of transgenic pea plants overexpressing the Na+/H+ gene from Arabidopsis thaliana and a positive association with salt-tolerant plant growth-promoting rhizobacteria (PGPR).

Employing transgenic plants as alternative systems to the conventional Escherichia coli, Pichia pastorisor baculovirus hosts to produce recombin-ant allergens may offer the possibility of having available edible vaccines in the near future. In this study, two EF-hand-type Ca 2+ -binding allergens from olive pollen, Ole e 3 and Ole e 8, were produced in transgenic Arabid-opsis thaliana plants.
