Article Abstract
In the present work, we report the discovery and complete genome sequence of a novel partitivirus identified from Brassica campestris L. ssp. chinensis, which we have named "Brassica campestris chinensis cryptic virus 1" (BCCV1). Next-generation sequencing (NGS) combined with adapter-ligation-mediated amplification allowed assembly of the full-length genome sequence of BCCV1. The genome of BCCV1 contains two dsRNA segments, dsRNA1 (1595 bp) and dsRNA2 (1591 bp), which encode a conserved RNA-dependent RNA polymerase (RdRp) and a putative capsid protein (CP), respectively. Homology searches and phylogenetic analysis of the 479-aa RdRp and 438-aa CP showed that BCCV1 is a new member of the genus Deltapartitivirus, family Partitiviridae. This is the first report of the identification of a member of the family Partitiviridae in Brassica campestris L. ssp. chinensis.

Global climate change is the reason behind extreme dry weather, which is the primary factor behind reduced crop growth and yield. To mitigate the detrimental effect of drought, biostimulants like Ascophyllum nodosum extract (ANE) and alginic acid (AA) are increasingly used, as they have demonstrated growth-promoting effects on plant. This study was designed to delve into the role of ANE and AA on drought affected rapeseed (Brassica campestris cv.

Unlabelled: Insect frass, a by-product of insect cultivation, represents an emergent category of agricultural waste. How to develop and make full use of this waste is a major issue to be addressed. In this study, the locust () frass was used as an organic fertilizer in a peach orchard, and its effects on soil were investigated, including physicochemical properties and microbial community over three consecutive years.
