AbstractMay-June (MJ) and April-July (AJ) precipitation at Huashan in north-central China has been reconstructed for the period A.D. 1600 to 1988 using tree-ring density and width fromPinus armandii. MJ precipitation (based on ring width and maximum latewood density) calibrated and cross-validated against local instrumental data more strongly than AJ precipitation (based only on ring width). A major drought was reconstructed for the mid- and late 1920s, confirmed by local documentary sources. This drought (culminating in 1929) was the most severe of the 389-yr period for MJ and second most severe for AJ, after an event ending in 1683. Neither reconstruction shows much spectral power at frequencies lower than 1 in 10 yr, but both show concentrations of power between 2.1 and 2.7 yr and 3.5 to 9 yr. There are significant correlations between the two reconstructions and a regional dryness/wetness index (DW) based on documentary sources, particularly at high frequencies. These correlations are focused in the 7.6- to 7.3-, 3.8- to 3.6-, and 2.5-yr periods. Using singular spectrum analysis, quasiperiodic behavior with a period close to 7.2 yr was identified in the MJ precipitation reconstruction and in the DW index based on documents.

Potato is an important crop in Shanxi province located in north-central China. During 2019-2020, 319 potato leaf samples were collected from eight locations distributed in three major potato production areas in Shanxi. Bio-chip detection kit revealed the presence of several potato viruses, and among them potato virus Y (PVY) was the most common one, reaching the incidence of 87.8% of all symptomatic samples. The immuno-captured multiplex reverse transcription (RT)-PCR was used to identify strains for all 280 PVY-positive samples, unveiling 242 samples infected with a single strain of PVY (86.4%) and 38 (13.6%) with a mixed infection. Of samples with a single-strain infection, PVY -SYR-II accounted for 102 (42.1%), followed by PVYN-Wi (33, 13.6%) , PVY -SYR-I (28, 11.6%), 261-4 (22, 9.1%), PVYNTNa (20, 8.3%), PVYNTNb (19, 7.9%), and PVY -SYR-III (18, 7.4%). Seven isolates representing different recombinants were selected for whole genome sequencing. Phylogenetic and recombination analyses confirmed the RT-PCR based strain typing for all seven strains of PVY found in Shanxi. SXKL-12 is the first SYR-III strain from potato reported from China. However, unlike that in other known SYR-III isolates, the region positioned from 1,764 to1,902 nt in SXKL-12 shared the highest sequence identity of 82.2% with an uncharacterized PVY isolate, JL-23, from China. Interestingly, the PVYN-Wi isolate SXZY-40 also possessed a more divergent sequence for the region positioned from 6,156 to 6,276 nt than other N-Wi isolates known to date, sharing the highest identity of 86.6% with an uncharacterized Chinese PVY isolate, JL-11. Pathogenicity analysis of dominant strains PVY -SYR-II and PVYN-Wi in six local popular potato cultivars revealed that Kexin 13, Helan 15 and Jizhangshu 12 were susceptible to these two strains with mild mottling or mosaic symptoms expression, while three cultivars, Jinshu 16, Qingshu 9, Xisen 6 were found fully resistant.
