Article Abstract
With the looming challenges of climate change and population pressure, understudied cereals hold notably untapped potential for future global food security and sustainable agriculture due to their unique nutritional profiles and notable stress resilience. Multiomics holds great promise in realizing the value of understudied cereals by understanding the genetic basis and molecular mechanisms regulating their unique traits; however, multiomic studies of understudied cereals still lag behind those of major cereals, hindering their genetic improvement and wide adoption in modern agriculture. Here, we discuss the limitations and challenges in multiomic studies of understudied cereals and how they can be overcome to enhance utilization of the traits unique to understudied cereals in improving both themselves and major cereals. We also offer a database specific to understudied cereals, including multiomics data from 12 understudied cereals and wild relatives for some of these, to serve the community.

Eukaryotic microorganisms are an important, but understudied, component of freshwater aquatic ecosystems, and are significant sources of mortality in early life stages of fishes in natural and aquaculture systems. The eukaryotic microbiome colonizing egg surfaces of the lake sturgeon (Acipenser fulvescens) was characterized from eggs collected in natural stream habitats and a streamside hatchery in the Cheboygan River watershed in MI, USA. The taxonomic diversity of members of the Kingdoms Fungi and Stramenopile associated with infections of lake sturgeon eggs during spawning is contributing to lake sturgeon mortality in the hatchery.

Tef (Eragrostis tef) is an indigenous African cereal that is gaining global attention as a gluten-free "superfood" with high protein, mineral, and fibre contents. However, tef yields are limited by lodging and by losses during harvest owing to its small grain size (150× lighter than wheat). Breeders must also consider a strong cultural preference for white-grained over brown-grained varieties.

Many endophytic fungi are approved as plant growth stimulants, and several commercial biostimulants have already been introduced in agricultural practice. However, there are still many species of fungi whose plant growth-promoting properties have been understudied or not studied at all. We examined the growth-promoting effect in spring barley () and Italian ryegrass () induced by three endophytic fungi previously obtained from the roots of / grasses.

With global climate change leading to increasing intensity and frequency of droughts, as well as the growing problem of soil salinization, these factors significantly affect crop growth, yield, and resilience to adversity. Oats are a cereal widely grown in temperate regions and are rich in nutritive value; however, the scientific literature on the response of oat to drought and salt stress has not yet been analyzed in detail. This study comprehensively analyzed the response of oat to drought stress and salt stress using data from the Web of Science core database and bibliometric methods with R (version4.
