TAAAAT and a novel motif, GCTTCA found in the oil palm stearoyl-ACP desaturase (SAD1) promoter are involved in regulating mesocarp-specific expression. Two key fatty acid biosynthetic genes, stearoyl-ACP desaturase (SAD1), and acyl-carrier protein (ACP3) in Elaeis guineensis (oil palm) showed high level of expression during the period of oil synthesis in the mesocarp [12-19 weeks after anthesis (w.a.a.)] and kernel (12-15 w.a.a.). Both genes are expressed in spear leaves at much lower levels and the expression increased by 1...

The development of oat endosperm is modified by chromatin and nuclei elimination, intrusive growth of cell walls, and polyploidisation of cell clones. The last event is correlated with somatic crossing-over. Grass endosperm is a variable tissue in terms of its cytogenetics and development. Free-nuclear syncytium and starchy and aleurone endosperm were the main focus of the research. These were studied in oat amphiploids (4x, 6x, and 8x) and parental species (2x, 4x, and 6x). What the levels of cytogenetic disorders and developmental anomalies in species versus hybrids are, and, what the factors are determining phenotypes of both tissue components, are open questions for oats...

REVIEW
James Reed, Anne Osbourn
Terpenoids are the most structurally diverse class of plant natural products with a huge range of commercial and medical applications. Exploiting this enormous potential has historically been hindered due to low levels of these compounds in their natural sources, making isolation difficult, while their structural complexity frequently makes synthetic chemistry approaches uneconomical. Engineering terpenoid biosynthesis in heterologous host production platforms provides a means to overcome these obstacles. In particular, plant-based production systems are attractive as they provide the compartmentalisation and cofactors necessary for the transfer of functional pathways from other plants...

This approach is quite promising to control plant viral diseases and create synthetic networks to better understand the structure/function relationship in RNA and proteins. Plant viruses are obligate intracellular parasites which causes enormous losses in crop yield worldwide. These viruses replicate into infected cells by highjacking host cellular machinery. Over the last two decades, diverse approaches such as conventional breeding, transgenic approach and gene silencing strategies have been used to control RNA viruses, but escaped due to high rate of mutation...

A new method based on mixing and wounding of callus tissue was used to transfer plastid or nuclear DNA between cells. Methods alternative to sexual hybridization can be powerful tools for crop improvement. We have developed a new hybridization technology based on wounding a mixed population of cells of two parents growing in vitro as callus ("cell grafting"), and have demonstrated the utility of this system for plastid or nuclear genome transfer. In our proof-of concept experiments, non-organized growing tissue (callus) from tobacco var...

PcWRKY33 is a transcription factor which can reduce salt tolerance by decreasing the expression of stress-related genes and increasing the cellular levels of reactive oxygen species (ROS). WRKY transcription factors play important roles in the regulation of biotic and abiotic stresses. Here, we report a group I WRKY gene from Polygonum cuspidatum, PcWRKY33, that encodes a nucleoprotein, which specifically binds to the W-box in the promoter of target genes to regulate their expression. The results from qPCR and promoter analysis show that expression of PcWRKY33 can be induced by various abiotic stresses, including NaCl and plant hormones...

We find that the DREB subfamily transcription factor, CmERF053, has a novel function to regulate the development of shoot branching and lateral root in addition to affecting abiotic stress. Dehydration-responsive element binding proteins (DREBs) are important plant transcription factors that regulate various abiotic stresses. Here, we isolated an APETALA2/ethylene-responsive factor (AP2/ERF) transcription factor from chrysanthemum (Chrysanthemum morifolium 'Jinba'), CmERF053, the expression of which was rapidly up-regulated by main stem decapitation...

Terbinafine induced a significant increase of squalene production. Terbinafine increased the expression levels of squalene synthase. Cyclodextrins did not work as elicitors due to the gene expression levels obtained. Plant sterols are essential components of membrane lipids, which contributing to their fluidity and permeability. Besides their cholesterol-lowering properties, they also have anti-inflammatory, antidiabetic and anticancer activities. Squalene, which is phytosterol precursor, is widely used in medicine, foods and cosmetics due to its anti-tumor, antioxidant and anti-aging activities...

Hypoxia enhances lignification of carrot root. Hypoxia stress was thought to be one of the major abiotic stresses that inhibiting the growth and development of higher plants. The genes encoding the plant alcohol dehydrogenase (ADH-P) were induced when suffering hypoxia. To investigate the impact of hypoxia on the carrot root growth, carrot plants were cultivated in the hydroponics with or without aeration. Morphological characteristics, anatomical structure, lignin content, and the expression profiles of DcADH-P genes and lignin biosynthesis-related genes were measured...

Arabidopsis thaliana (thale cress) has a past, current, and future role in the era of synthetic biology. Arabidopsis is one of the most well-studied plants with a wealth of genomics, genetics, and biochemical resources available for the metabolic engineer and synthetic biologist. Here we discuss the tools and resources that enable the identification of target genes and pathways in Arabidopsis and heterologous expression in this model plant. While there are numerous examples of engineering Arabidopsis for decreased lignin, increased seed oil, increased vitamins, and environmental remediation, this plant has provided biochemical tools for introducing Arabidopsis genes, pathways, and/or regulatory elements into other plants and microorganisms...

BcMF23a contributes to pollen wall development via influencing intine construction, which, in turn, influences pollen tube growth. Pollen wall, the morphological out face of pollen, surrounds male gametophyte and plays an important role in plant reproduction. Pectin methylesterases (PMEs) are involved in pollen wall construction by de-esterifying pectin of the intine. In this study, the function of a putative pectin methylesterase gene, Brassica campestris Male Fertility 23a (BcMF23a), was investigated. Knockdown of BcMF23a by artificial microRNA (amiRNA) technology resulted in abnormal pollen intine formation outside of the germinal furrows at the binucleate stage...

OsEXPA10 gene coordinates the balance between rice development and biotic resistance. Expansins are proteins that can loosen the cell wall. Previous studies have indicated that expansin-encoding genes were involved in defense against abiotic stress, but little is known about the involvement of expansins in biotic stress. Brown planthopper (BPH) is one of the worst insect pests of rice in the Asia-Pacific planting area, and many efforts have been made to identify and clone BPH-resistance genes for use in breeding resistant cultivars...

REVIEW
Yan Li, Hsihua Wang, Yang Zhang, Cathie Martin
Tomato has a relatively short growth cycle (fruit ready to pick within 65-85 days from planting) and a relatively high yield (the average for globe tomatoes is 3-9 kg fruit per plant rising to as much as 40 kg fruit per plant). Tomatoes also produce large amounts of important primary and secondary metabolites which can serve as intermediates or substrates for producing valuable new compounds. As a model crop, tomato already has a broad range of tools and resources available for biotechnological applications, either increased nutrients for health-promoting biofortified foods or as a production system for high-value compounds...

Yongqiang Zhang, Zhongjuan Liu, Xiaoyun Wang, Jianfeng Wang, Kai Fan, Zhaowei Li, Wenxiong Lin
DELLA proteins' negative regulation of dark-induced senescence and chlorophyll degradation in Arabidopsis is through interaction with WRKY6 and thus repression of its transcriptional activities on senescence-related genes. Senescence is an intricate and highly orchestrated process regulated by numerous endogenous and environmental signals. Gibberellins (GAs) and their signaling components DELLA proteins have been known to participate in the regulation of senescence. However, the mechanism of the GA-DELLA system involved in the senescence process remains largely unclear...

A rice receptor-like kinase gene OSBBS1/OsRLCK109 was identified; this gene played vital roles in leaf senescence and the salt stress response. Early leaf senescence can cause negative effects on rice yield, but the underlying molecular regulation is not fully understood. bilateral blade senescence 1 (bbs1), an early leaf senescence mutant with a premature senescence phenotype that occurs mainly performing at the leaf margins, was isolated from a rice mutant population generated by ethylmethane sulfonate (EMS) treatment...

Global gene expression analysis indicates host stress responses, mainly those mediated by SA, associated to the tolerance to sticky disease symptoms at pre-flowering stage in Carica papaya. Carica papaya plants develop the papaya sticky disease (PSD) as a result of the combined infection of papaya meleira virus (PMeV) and papaya meleira virus 2 (PMeV2), or PMeV complex. PSD symptoms appear only after C. papaya flowers. To understand the mechanisms involved in this phenomenon, the global gene expression patterns of PMeV complex-infected C...

Rice cytoplasmic APX2 is a pleiotropic protein, densely distributed around chloroplasts. It plays key roles in H2 O2 homeostasis and chloroplast protection, and is related to plant architecture and fertility regulation. Ascorbate peroxidases (APXs) catalyze the conversion of H2 O2 into H2 O. In this report, we systematically investigated the function of cytosolic APX2 using a T-DNA knockout mutant. Loss of OsAPX2 altered rice architecture including shoot height and leaf inclination, resulting in shoot dwarfing, leaf dispersion and fertility decline...

Inclusion of carbon nanoparticles in growth medium accelerates timing to flower by down-regulating phytochrome B in a CONSTANS-independent but photoperiod-dependent manner in Arabidopsis thaliana. Despite the recognized importance of nanoparticles in plant development over the last decade, the effect of carbon nanoparticles (CNPs) on plant processes such as photomorphogenesis and flowering time control is poorly understood. We explored the uptake, accumulation and effect of CNPs on seedling development and flowering time control in Arabidopsis thaliana (At)...
