Genesis Theme custom template

Would appreciate help in creating my custom template so that CustomPress works with Genesis theme. This is what I created, however, I really do not know php

<?php

/**

* Single CPT Template: plant-template.php

*

*/



remove_action('genesis_loop', 'genesis_do_loop');



add_action('genesis_loop', 'gt_custom_loop');

function gt_custom_loop() {



<?php echo do_shortcode('[tax id="plant_type" before="your text before " separator=", " after=" your text after"]');  ?>



}



genesis();
