The invention discloses an application of a broccoli BoCyt f gene in regulating and controlling plant senescence, and is characterized in that the nucleotide sequence of the BoCyt f gene is shown as SEQ ID NO.1. The function of BoCyt f is verified in a transgenic overexpression mode, and overexpression of the BoCyt f gene in arabidopsis thaliana can significantly promote leaf yellowing and senescence and accelerate chlorophyll degradation, so that the Broccoli BoCyt f gene can be used for regulating and controlling plant senescence. Active oxygen accumulation is induced, and PCD related gene expression is up-regulated; the invention has the advantages that the forward regulation effect of the BoCyt f gene in plant PCD and aging is defined for the first time, and a new target gene is provided for plant anti-aging breeding and postharvest preservation technology.

A new and distinct cultivar of Sansevieria plant named ‘HANSOTI59’ is disclosed, characterized by foliage variegation in the form of linear bands and streaks of different grey-greens and creams along the length of the leaf, a dark green leaf border and a golden yellow suffusion towards the base of the leaf. Unusually upright, relatively narrow leaves give a particularly vertically oriented narrow rosette of greyish-green to cream-streaked leaves. Unique slow changing of the variegation pattern and color of new leaves as more leaves emerge from an older plant to give a creamier look as the plant ages. The new cultivar can be classified in the Compact Sansevieria Group. The new variety is a Sansevieria, typically produced as an ornamental plant.

This invention discloses a highly efficient irrigation method for promoting grain filling by regulating the chlorosis trait in rice. This method involves shallow-water-drying quantitative irrigation, where water is naturally allowed to dry from a shallow water layer to a specified soil water potential before being re-irrigated to a shallow water layer, and this cycle is repeated. First, the presence of chlorosis in rice plants is determined based on a leaf color threshold. Then, for varieties exhibiting chlorosis, the degree of soil drying at each growth stage is quantitatively determined based on the panicle type of different rice subspecies and leaf age patterns. This method, by controlling field water potential, creates mild water stress on the plants, thereby regulating plant senescence (i.e., chlorosis trait). It also enhances the activity of key enzymes in sucrose-starch metabolism in the stem sheath and grains, thus promoting the translocation of assimilates from the stem sheath to the grains, increasing grain filling rate, and achieving yield increase.

The invention provides a BrRAV8 gene for delaying flowering cabbage leaf senescence and application of the BrRAV8 gene. A nucleotide sequence of the BrRAV8 gene is shown as SEQ ID NO.1, or has a nucleotide sequence complementary with the sequence shown as SEQ ID NO.1, or has 75% or more homology with the nucleotide sequence shown as SEQ ID NO.1, and the BrRAV8 gene can also be coded to participate in plant senescence regulation and control, and can be applied to plant senescence regulation and control. The invention particularly relates to a DNA molecule for inhibiting leaf senescence protein. The gene BrRAV8 can participate in the senescence regulation and control process, the senescence of leaves of the flowering cabbage is inhibited, and the shelf life of the harvested flowering cabbage is prolonged.
