Integrative transcriptomic analysis reveals the molecular responses of tobacco to magnesium deficiency.

Introduction: Magnesium (Mg) is a crucial macronutrient for plants. Understanding the molecular responses of plants to different levels of Mg supply is important for improving cultivation practices and breeding new varieties with efficient Mg utilization.

Methods: In this study, we conducted a comprehensive transcriptome analysis on tobacco ( L.

Integrative analysis of the transcriptome and proteome reveals the molecular responses of tobacco to boron deficiency.

Background: Boron (B) is an essential micronutrient for plants. Inappropriate B supply detrimentally affects the productivity of numerous crops. Understanding of the molecular responses of plants to different B supply levels would be of significance in crop improvement and cultivation practices to deal with the problem.

Combined transcriptome and proteome analysis revealed the molecular regulation mechanisms of zinc homeostasis and antioxidant machinery in tobacco in response to different zinc supplies.

Zinc (Zn) is an essential micronutrient for plants. Adequate regulation of Zn uptake, transport and distribution, and adaptation to Zn-deficiency stress or Zn-excess toxicity are crucial for plant growth and development. However, little has been done to understand the molecular responses of plants toward different Zn supply levels.

Corrigendum: Magnesium application improves the morphology, nutrients uptake, photosynthetic traits, and quality of tobacco ( L.) under cold stress.

Magnesium application improves the morphology, nutrients uptake, photosynthetic traits, and quality of tobacco ( L.) under cold stress.

Cold stress is one of the major constraints limiting the productivity of many important crops, including tobacco ( L.) production and quality worldwide. However, the role of magnesium (Mg) nutrition in plants has been frequently overlooked, especially under cold stress, and Mg deficiency adversely affects plant growth and development.

Identification of stably expressed QTL for heading date using reciprocal introgression line and recombinant inbred line populations in rice.

Two sets of reciprocal introgression lines (ILs) and a population of recombinant inbred lines (RILs) derived from the cross between japonica cultivar Xiushui09 and indica breeding line IR2061-520-6-9 (abbreviated as IR2061) were used to identify QTL for heading date (HD). Phenotyping was conducted in Hainan Island for two winter seasons (2007 and 2009). Nine QTLs were detected in the ILs with Xiushui09 background (XS-ILs), and four of which were repeatedly mapped across 2 years.

Structural and functional characterization of a pollen-specific promoter NTPp13 in tobacco.

A novel 407 bp nucleotide sequence NTPp13 was isolated from tobacco (Nicotiana tabacum L.) by PCR, its structure and function were characterized. The NTPp13 sequence was highly homologous with the pollen-specific expression promoter Zm13 from maize (Zea mays L.
