An abietane diterpenoid is a potent activator of systemic acquired resistance.

Abstract: Abietane diterpenoids are major constituents of conifer resins that have important industrial and medicinal applications. However, their function in plants is poorly understood. Here we show that dehydroabietinal (DA), an abietane diterpenoid, is an activator of systemic acquired resistance (SAR), which is an inducible defense mechanism that is activated in the distal, non-colonized, organs of a plant that has experienced a local foliar infection. DA was purified as a SAR-activating factor from vascular sap of Arabidopsis thaliana leaves treated with a SAR-inducing microbe. Locally applied DA is translocated through the plant and systemically induces the accumulation of salicylic acid (SA), an important activator of defense, thus leading to enhanced resistance against subsequent infections. The NPR1 (NON-EXPRESSOR OF PR GENES1), FMO1 (FLAVIN-DEPENDENT MONOOXYGENASE1) and DIR1 (DEFECTIVE IN INDUCED RESISTANCE1) genes, which are critical for biologically induced SAR, are also required for the DA-induced SAR, which is further enhanced by azelaic acid, a defense priming molecule. In response to the biological induction of SAR, DA in vascular sap is redistributed into a SAR-inducing 'signaling DA' pool that is associated with a trypsin-sensitive high molecular weight fraction, a finding that suggests that DA-orchestrated SAR involves a vascular sap protein(s).

Reformulation of DFT + U as a pseudohybrid hubbard density functional for accelerated materials discovery

Abstract: Insulators and semiconductors are used extensively in industry and a data-driven approach is necessary to investigate the properties of these materials. A new theory of electronic properties is consistent with findings from experiments of transition-metal oxides.

Everything You Wanted to Know about Smart Health Care: Evaluating the Different Technologies and Components of the Internet of Things for Better Health

Abstract: The Internet-of-Things (IoT) has taken over the business spectrum, and its applications vary widely from agriculture and health care to transportation. A hospital environment can be very stressful, especially for senior citizens and children. With the ever-increasing world population, the conventional patient-doctor appointment has lost its effectiveness. Hence, smart health care becomes very important. Smart health care can be implemented at all levels, starting from temperature monitoring for babies to tracking vital signs in the elderly.
