  • Patent number: 12285013
    Abstract: The present invention relates to a processing method for increasing seed production rate of seed fruits of Cucumis sativus L., comprising the following steps: (1) preparing a plant growth regulator according to a formula proportion; (2) selecting seed fruits of Cucumis sativus L. growing naturally in a greenhouse and reaching a pollination stage, and dipping female flowers thereof with the plant growth regulator prepared in step (1) before pollination; (3) picking male flowers for pollination after the female flowers are completely dry; (4) dipping the pollinated female flowers again; (5) conducting field routine cultivation management. The present invention uses a DNA methyltransferase inhibitor “5-azacytidine” (C8H12N4O5) to treat the seed fruits of Cucumis sativus L. by soaking and dipping, wherein 5-azacytidine increases seed production efficiency by reducing fruit length of the seed fruits, reducing fruit weight and reducing nutrient loss for fruit growth.

  • Publication number: 20250104810
    Abstract: The present invention discloses a gene mining method and system based on transcriptome and DNA methylome. The gene mining method comprises: acquiring samples; performing transcriptome sequencing on the samples and analyzing data obtained by the sequencing to obtain differentially expressed genes; performing DNA methylation sequencing on the samples and analyzing data obtained by the sequencing to obtain differentially methylated genes; performing gene function enrichment on the obtained differentially expressed genes and differentially methylated genes to obtain a molecular protein-protein interaction (PPI) network; and performing gene clustering with the molecular PPI network to identify target genes. The present invention solves the problems that it takes time and effort to mine core genes of existing transcriptome and methylome and the result is not accurate enough. The present invention mines target genes by organically integrating originally isolated transcriptome data and DNA methylome data.

    Abstract: Disclosed is a circuit for converting a temperature change amount into a voltage change amount in a motor drive system, including a positive temperature change rate voltage generation module, a circuit bias module, and a temperature detection module that are integrated on a same substrate. An external power supply voltage is processed by the positive temperature change rate voltage generation module and the circuit bias module, and then inputted to the temperature detection module. The temperature detection module detects in real time the temperature change amount in the motor drive system, convert the temperature change amount into the voltage change amount, and transfer the voltage change amount to the circuit bias module, to allow the circuit bias module to output the voltage change amount. In this way, the conversion from the temperature change amount into the voltage change amount is realized.
