Abstract
AbstractZinnia peruviana (Asteraceae) is an annual flowering plant cultivated in various gardens of Mysore, the south of Karnataka state, India. During 2021, phytoplasma‐like symptoms such as virescence and phyllody were observed on Zinnia in Mysore local gardens. A total of 10 symptomatic and five asymptomatic samples were collected, and the DNA was amplified by PCR using primers specific to 16S RNA and secA genes. The nucleotide sequence analysis showed that the 16S RNA and SecA gene sequences

Influence of ‘Candidatus Liberibacter solanacearum’ infection on carrot root weight in Germany

Abstract
AbstractInfection with the bacterium ‘Candidatus Liberibacter solanacearum’ (Lso) is suspected to cause severe damage in carrot leading to high carrot weight loss. This study investigates three main aspects: (i) whether there is a reduction of carrot root weight under field conditions due to Lso infection; (ii) the correlation between Lso infection rate in carrot plants and occurrence of the psyllid Trioza apicalis as the known vector for Lso in carrot, and (iii) the comparison between symptoms

Abstract
Citrus Huanglongbing, one of the most devastating citrus diseases, is caused by Candidatus Liberibacter asiaticus (CLas). Polyamines are aliphatic nitrogen-containing compounds that play important roles in disease resistance. However, the role of polyamine metabolism in the tolerance of citrus to infection with CLas have not been extensively studied. We used HPLC and UPLC-Q/TOF-MS to detect the contents of nine polyamine metabolism-related compounds (PMRCs) in six citrus cultivars with varying
