Summary: The study found that spraying CaCl2, MgCl2, KCl, and K2SO4 can reduce the occurrence of cucumber powdery mildew. There is a significant negative correlation between salt concentrations and disease severity. Chloride salts are more effective than sulfate salts. Cucumbers at different growth stages have different nutrient requirements, and spraying treatments are more effective than fertigation treatments.

Summary: This review summarizes the efforts made in the past 50 plus years to identify resistant sources against powdery mildew and downy mildew in melon germplasm. A total of 239 melon accessions resistant to powdery mildew and 452 accessions resistant to downy mildew have been identified. Among these resistant sources, C. melo var. cantalupensis accessions PMR 45, PMR 5, PMR 6, and WMR 29, as well as C. melo var. momordica accessions PI 124111, PI 124112, and PI 414723, are considered as the most valuable germplasm. Genetic mapping has identified several dominant genes, recessive genes, and QTLs conferring resistance to both powdery mildew and downy mildew.

Summary: Under field conditions, plants often face multiple stresses and need to adapt accordingly. This study investigated the interaction between drought stress and powdery mildew (PM) infection in tomatoes. The results showed that drought stress reduced fungal infection in susceptible genotypes and had varying effects on resistant genotypes. At the molecular level, genes involved in ABA, SA, and ethylene pathways were highly induced under combined stress.

Summary: Powdery mildew (PM) of wheat is a major disease that affects yield and quality worldwide. Over 240 genes and quantitative trait loci (QTLs) related to PM resistance have been discovered on all 21 wheat chromosomes. Wheat landraces have emerged as important sources of genetic diversity for developing new resistant cultivars, but many of them have not been characterized for PM resistance. The challenge lies in the polygenic nature of PM resistance and the lack of consistent disease pressure in trials.

Summary: By experimenting with two grafting techniques, the study found that flute grafting had higher initial survival rates, but patch grafting showed similar survival rates in the later stages with a higher scion survival rate in a certain welding class. Different welding classes exhibited visual differences, but anatomically, all classes displayed vascular connections. Visual evaluation of welding quality underestimated scion survival rates, while vascular connections and parenchymatous tissue development showed promise for diagnosing grafting success.

Summary: Canga is a harsh environment with high biodiversity and endemism, but it is threatened by human activities. The Serra do Cabral mountain in Minas Gerais, Brazil, is the habitat of a micro-endemic species called canga-Syagrus graminifolia subsp. cabraliensis. This species has unique features and is affected by fires and road traffic. The absence of other populations in nearby areas is explained by predation of its seeds by beetle larvae. Due to geographical isolation and morpho-anatomical novelties, this taxon is proposed as a new species called Syagrus cabraliensis. Given the risk of extinction, it is urgent to include the population area of S. cabraliensis in Serra do Cabral State Park and divert the road.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
