Disclosed herein are methods for controlling invertebrate pest infestations, particularly in plants; compositions and insecticidal polynucleotides useful in such methods; and plants having improved resistance to the invertebrate pests. More specifically, insecticidal polynucleotides and methods of use thereof for modifying the expression of genes in an insect pest, particularly through RNA interference are disclosed.

The present disclosure provides a rice planthopper-sensitivity gene BGIOSGA015651 and the use thereof. The applicant found a gene BGIOSGA015651 for regulating rice planthopper-resistance by studying on rice varieties BG1222 and TN1. The gene expression level of BGIOSGA015651 in the insect-resistant variety is hundreds of times or more different from that of the insect-susceptible variety. The expression of this gene can be reduced or knocked out by molecular breeding methods or genetic engineering methods, resulting in that the insect-susceptible plant can obtain high insect-resistance. The resistance level of the insect-susceptible rice variety TN1 is of level 9 before knock-out, and the resistance level thereof is significantly increased to level 0-1 after the rice planthopper-sensitivity gene BGIOSGA015651 is knocked out. The gene and the encoded protein thereof can be used for plant genetic improvement, and the obtained rice for breeding can be widely promoted in a wide range of rice growing areas, and has high economic values and outstanding ecological benefits.

The present invention concerns insecticidal peptides and their uses, in particular as plant protection agents. It also concerns transgenic organisms, in particular transgenic plants, expressing said peptides.

The disclosure provides nucleic acids, and variants and fragments thereof, obtained from strains of Bacillus thuringiensis encoding polypeptides having pesticidal activity against insect pests, including Lepidoptera. Particular embodiments of the disclosure provide isolated nucleic acids encoding pesticidal proteins, pesticidal compositions, DNA constructs, and transformed microorganisms and plants comprising a nucleic acid of the embodiments. These compositions find use in methods for controlling pests, especially plant pests.

The invention provides seed and plants of tomato hybrid SVTC0630. The invention thus relates to the plants, seeds, and tissue cultures of tomato hybrid SVTC0630 and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

Provided are a RNAi target gene that is lethal to aphids and the use thereof. Specifically, provided are six gene fragments resulting in the death of aphid nymphs and/or death thereof in the adult stage based on RNA interference technology. The death of the aphids can be caused by spraying a dsRNA-containing composition onto plants to feed aphids or directly spraying same onto the skin of the aphids.

The compositions and methods disclosed relate to DNA compositions, plant cells, seeds, plant parts that relate to maize plants with increased grain yield trait. Also provided are assays for detecting the presence of the maize DP-202216-6 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.

Lettuce (Lactuca sativa) plants exhibiting resistance to Nasonovia ribisnigri biotype Nr:1 are provided, together with methods of producing, identifying, or selecting plants or germplasm with a Nasonovia ribisnigri biotype Nr:1 resistance phenotype. Such plants include lettuce plants comprising introgressed genomic regions conferring pest resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed loci, are further provided.

Described herein are modified plants, plant cells, and plant seeds that have at least one mutant loss-of-function JAZ gene and at least one loss-of-function cdk8 gene. Such plants are highly resistant to pests and environmental stress and have restored growth and increased seed yield compared to plant lines with a jazD genetic background.

The disclosure relates to a cotton variety, designated PX2A31W3FE, the plants and seeds of the cotton variety PX2A31W3FE, methods for producing a cotton plant, either varietal or hybrid, produced by crossing the cotton variety PX2A31W3FE with itself or with another cotton plant, hybrid cotton seeds and plants produced by crossing the variety PX2A31W3FE with another cotton variety or plan, methods for producing a cotton plant containing in its genetic material one or more transgenes, and the transgenic cotton plants produced by that method. This disclosure also relates to cotton varieties derived from cotton variety PX2A31W3FE, to methods for producing other cotton varieties derived from cotton variety PX2A31W3FE, and to the varieties derived by the use of those methods.
