Abstract

The invention discloses a soybean photoreceptor GmPLP1 and a coding gene and application thereof. The protein provided by the invention is named as GmPLP1 and is a protein as described in the following (1) or (2): (1) protein with an amino acid sequence as shown in the sequence 2 in a sequence table; and (2) protein which is derived from (1) by substituting and / or deleting and / or adding one or more amino acid residues of the amino acid sequence of the sequence 2, and is associated with plant traits. The plant traits comprise at least one of the following (1)-(10): (1) branch number; (2) time of flowering; (3) plant height; (4) blade area; (5) distance between nodes; (6) root length; (7) photosynthetic rate; (8) stress tolerance; (9) stem diameter; and (10) node number. The photoreceptor gene GmPLP1 disclosed by the invention can be used for changing the plant morphology, increasing the plant branches and changing the time of flowering and ripening of the plant, and has great importance for plant breeding and research on the function and action mechanism of the photoreceptor gene.

Description

technical field

[0001] The invention relates to a soybean photoreceptor GmPLP1 and its coding gene and application. Background technique

[0002] Light is the most extensive, most obvious and most important environmental factor affecting plant growth and development. The regulation of light on plants is manifested in: photosynthesis efficiency, respiration intensity, differentiation of apical meristem to floral primordia (photoperiodic response), tropism and so on. The photoperiod response directly determines the yield, quality and adaptability of crops. So far, only the molecular mechanism of the light response of the model plant Arabidopsis thaliana has been studied extensively and in detail.

[0003] In the light response, plants perceive external light signals through photoreceptors and transmit the light signals to the circadian rhythm clock system, thereby activating or inhibiting the expression of photoperiod flowering time genes to control the flowering time of pla...
