LncRNA cis- and trans-regulation provides new insight into drought stress responses in wild barley.

Drought is one of the most common abiotic stresses that affect barley productivity. Long noncoding RNA (lncRNA) has been reported to be widely involved in abiotic stress, however, its function in the drought stress response in wild barley remains unclear. In this study, RNA sequencing was performed to identify differentially expressed lncRNAs (DElncRNA) among two wild barley and two cultivated barley genotypes.

Transcriptomic Analysis Reveals the Flavonoid Biosynthesis Pathway Involved in Rhizome Development in Hua.

Hua () rhizomes are rich in flavonoids and other secondary metabolites, exhibiting remarkable antioxidant, anti-tumor, and immunomodulatory effects. flavonoid-biosynthesis-related genes have been characterized already. However, a comprehensive overview of flavonoid biosynthesis pathways is still absent.

Analysis of chitinase gene family in barley and function study of HvChi22 involved in drought tolerance.

Background: Chitinase (Chi) is a pathogenesis-related protein, also reported to play an important role in plant responses to abiotic stress. However, its role in response to abiotic stress in barley is still unclear.

Results: In this study, a total of 61 Chi gene family members were identified from the whole genome of wild barley EC_S1.

Genome-wide identification of cold-tolerance genes and functional analysis of IbbHLH116 gene in sweet potato.

Sweet potato (Ipomoea batatas L.) originated from South America; therefore, it is vulnerable to low temperature. Here, the evolutionary analysis of 22 cold-responsive genes in 35 plant species revealed that the identified MYC-type basic helix-loop-helix (bHLH) transcription factors exhibit diverse structures.
