Review. From stressed to success: Unveiling the secret memory of gymnosperms

Epigenetic stress memory in gymnosperms is the topic of a new review by Fossdal et al. Gymnosperms are long-lived, cone-bearing, tough trees, known to tolerate episodic stress. Their adaptive traits to stress are not passed on in a straightforward way, conforming to classical Mendelian inheritance. Instead, adaptive responses in gymnosperms are a result of epigenetic […]

Branched chain amino acids accumulation contributes to drought tolerance in rice

The accumulation of metabolites such as proline as compatible osmolytes is a protective mechanism against drought stress in plants. Similarly, under drought conditions, there is an observable increase in the accumulation of branched-chain amino acids (BCAAs), including the essential amino acids isoleucine, leucine, and valine. Shim et al. investigated rice OsDIAT (DROUGHT-INDUCED BRANCHED-CHAIN AMINO ACID […]

Loneliness Among Sexual Minorities

Humans are social creatures with a strong desire for companionship, intimacy, and belonging. Loneliness occurs when the relationships a person has do not match their desired relationships. Social loneliness is the absence of satisfactory social connections with friends, family, colleagues, and neighbors who provide support, belonging, companionship, and community. Emotional loneliness is the absence of […]

Overcoming arsenic stress using iron-oxide doped rice biochar

Arsenic (As) contamination in soil influences the physio-chemical properties of plants. Majumdar et al. propose the use of rice biochar (RBC) doped with iron oxide (IO) nanoparticles, an eco-friendly composite, to minimize As toxicity in plants. Rice plants grown on As-contaminated soil with the composite showed reduced stress markers, whereas the control plants grown in […]
