Recently, nitric oxide (NO), a redox-related signaling molecule, is considered to be a key regulator in plant growth and development as well as response to abiotic stresses. Heavy metal (HM) stress is one of the most serious threats to affect crop growth and production. HM stress attributes to the production of reactive oxygen species (ROS), leading to oxidative stress in plants. Thus, to minimize the toxic effects of HM stress, plants directly or indirectly activate different ROS-scavenging mechanisms comprised antioxidative enzymes and non-enzymatic antioxidants. Understanding the roles of NO is essential to elucidate how NO activates the appropriate set of responses to HM stress. Moreover, the regulation of key genes or proteins is very important in response to stress stimuli. Therefore, here we focus on the recent knowledge concerning the alleviating effect of NO on HM stress, covering from HM iron accumulation to antioxidant system to related gene and protein expression.

Background: The Sec14 domain is an ancient lipid-binding domain that evolved from yeast Sec14p and performs complex lipid-mediated regulatory functions in subcellular organelles and intracellular traffic. The Sec14 family is characterized by a highly conserved Sec14 domain, and is ubiquitously expressed in all eukaryotic cells and has diverse functions. However, the number and characteristics of Sec14 homologous genes in soybean, as well as their potential roles, remain understudied.

In vertebrates and plants, dsRNA plays crucial roles as PAMP and as a mediator of RNAi. How higher fungi respond to dsRNA is not known. We demonstrate that Magnaporthe oryzae (Mo), a globally significant crop pathogen, internalizes dsRNA across a broad size range of 21 to about 3000 bp.

Nano-biochar considers a versatile and valuable sorbent to enhance plant productivity by improving soil environment and emerged as a novel solution for environmental remediation and sustainable agriculture in modern era. In this study, roles of foliar applied nanobiochar colloidal solution (NBS) on salt stressed tomato plants were investigated. For this purpose, NBS was applied (0%, 1% 3% and 5%) on two groups of plants (control 0 mM and salt stress 60 mM).
