The cabbage looper, Trichoplusia ni, is a serious pest of cruciferous crops such as cabbage, cauliflower, collard/spring greens, and horseradish, with a major financial impact. Despite its significant financial importance, there has been little study on the characterization of Cytochrome P450 (CYP450) genes, which are critical components in the control of metabolic activities. This study discovers and investigates 19 CYP450 genes in T.

The Cholistan Desert of Pakistan harbors unique reptile diversity, including ecologically significant agamid lizards of the genera Calotes and Uromastyx, yet their genetic structure remains poorly understood. This study presents the first mitochondrial DNA barcode assessment of these taxa in the region, analyzing 658 bp of the cytochrome c oxidase I (COI) gene from 19 specimens collected across seven desert sites. We employed a combination of distance-based (p-distance, K2P) and phylogenetic methods (Maximum Likelihood, Bayesian Inference) to evaluate genetic diversity and evolutionary relationships.

Nonexpressor of pathogenesis-related 1 (NPR1) is crucial for activating the plant immune system through the signaling molecule salicylic acid (SA), which triggers systemic acquired resistance (SAR) in Arabidopsis. In this study, three putative genes associated with NPR1 from Arabidopsis have been identified in the genome of Theobroma cacao, namely, TcNPR1, TcNPR2, and TcNPR3, suggesting a functional diversification among the three gene entities. Phylogenetic analysis revealed that TcNPR1 and TcNPR2 branched alongside their Arabidopsis orthologs, NPR1 and NPR2, indicating that these genes maintain a conserved role in SA signaling pathways across different species.

The (citrus) plant produces various phytohormones due to the significant involvement of the carotenoid cleavage oxygenase () gene family in its growth and development. genes can be divided into two main categories: (9-cis-epoxy carotenoid dioxygenase), responsible for abscisic acid (ABA) production, and (carotenoid cleavage dioxygenase), involved in pigment and strigolactone formation. To better understand the roles and positions of gene members in relation to these hormones, researchers analyzed the clementine genome.

Article Synopsis
  • The BAX inhibitor-1 (BI-1) gene family in plants regulates cell death under stress, which is important for plant development and maintaining tissue health.
  • A study on cucumber identified five BI-1 genes, revealing their evolutionary relationships, molecular characteristics, and protein interactions, highlighting their potential roles in stress response.
  • Elevated expression of certain BI-1 genes during cold stress and in response to viral infection suggests they could be key to developing cold-tolerant and virus-resistant cucumber varieties through breeding or genetic engineering.

Phenylalanine ammonia lyase (PAL) is a widely studied enzyme in plant biology due to its role in connecting primary metabolism to secondary phenylpropanoid metabolism, significantly influencing plant growth, development, and stress response. Although PAL genes have been extensively studied in various plant species but their exploration in cucumber has been limited. This study successfully identified 11 CsPAL genes in Cucumis sativus (cucumber).

Article Synopsis
  • Chili pepper cultivation in the Indian subcontinent faces challenges from viral diseases, highlighting the need for eco-friendly control methods and a better understanding of viral resistance mechanisms.
  • The NONEXPRESSOR OF PATHOGENESIS-RELATED GENES 1 (NPR1) genes play a key role in providing resistance to various pathogens by activating systemic acquired resistance (SAR), but limited knowledge about these genes in chili restricts breeding for disease resistance.
  • Analysis using bioinformatics identified five crucial genes in chili that are linked to biotic stress responses, with findings showing that the resistant variety (V1) has enhanced defense mechanisms against begomovirus infection compared to the susceptible variety (V2).

Carotenoid cleavage oxygenases (CCOs) enzymes play a vital role in plant growth and development through the synthesis of apocarotenoids and their derivative. These chemicals are necessary for flower and fruit coloration, as well as the manufacture of plant hormones such as abscisic acid (ABA) and strigolactones, which control a variety of physiological processes. The CCOs gene family has not been characterized in Arachis hypogaea.

The growth and productivity of maize are severely affected by soil salinity. The crucial determinants for the future performance of plants are productive for seed germination and seedling establishment; however, both stages are liable to soil salinity. For grain, maize is an economically significant crop sensitive to abiotic stresses.
